## Overview
Implemented complete database schema and repositories for Anvil-branded cloud products, including regions, instances, pricing, and transfer pricing.
Anvil-branded cloud products with automated pricing sync from source providers (Linode, Vultr).
## Implementation Summary
**Key Features:**
- USD retail pricing only (simplified schema)
- Automatic pricing sync: wholesale × 1.21 = retail
- Source mapping via `source_instance_id` and `source_region_id`
### 1. Database Migration (004_anvil_tables.sql)
## Database Schema
Created 4 new tables with proper indexes, triggers, and foreign key constraints:
#### anvil_regions
- Maps Anvil-branded regions to source provider regions
- Contains 6 initial regions (Tokyo 1-3, Osaka 1-2, Seoul 1)
- Links to existing `regions` table via `source_region_id`
### anvil_regions
Maps Anvil regions to source provider regions.
**Columns:**
- `id`, `name` (unique), `display_name`, `country_code`
- `source_provider`, `source_region_code`, `source_region_id` (FK)
- `source_provider` (linode, vultr)
- `source_region_code`, `source_region_id` (FK to `regions.id`)
- `active`, `created_at`, `updated_at`
**Initial Data:**
```
anvil-tyo1 → Linode ap-northeast (region_id: 26)
anvil-tyo2 → Linode jp-tyo-3 (region_id: 3)
anvil-tyo3 → Vultr nrt (region_id: 323)
anvil-osa1 → Linode jp-osa (region_id: 13)
anvil-osa2 → Vultr itm (region_id: 314)
anvil-sel1 → Vultr icn (region_id: 313)
```
**Region Mappings:**
| Anvil Region | Source Provider | Source Region |
|-------------|-----------------|---------------|
| anvil-tyo1 | Linode | ap-northeast |
| anvil-tyo2 | Linode | jp-tyo-3 |
| anvil-tyo3 | Vultr | nrt |
| anvil-osa1 | Linode | jp-osa |
| anvil-osa2 | Vultr | itm |
| anvil-sel1 | Vultr | icn |
#### anvil_instances
- Defines Anvil product specifications
- Supports categories: vm, gpu, g8, vpu
- GPU-specific fields: `gpu_model`, `gpu_vram_gb`
### anvil_instances
Anvil product specifications.
**Columns:**
- `id`, `name` (unique), `display_name`, `category`
- `id`, `name` (unique), `display_name`, `category` (vm, gpu, g8, vpu)
- `vcpus`, `memory_gb`, `disk_gb`
- `transfer_tb`, `network_gbps`
- `gpu_model`, `gpu_vram_gb` (nullable)
- `gpu_model`, `gpu_vram_gb` (nullable, for GPU instances)
- `active`, `created_at`, `updated_at`
#### anvil_pricing
- Retail pricing with cost tracking
- Auto-calculates KRW prices using exchange rates
- Links to both Anvil instances/regions and source instances
### anvil_pricing
Retail pricing in USD. Auto-synced from source provider pricing.
**Columns:**
- `id`, `anvil_instance_id` (FK), `anvil_region_id` (FK)
- `hourly_price`, `monthly_price` (retail USD)
- `hourly_price_krw`, `monthly_price_krw` (retail KRW)
- `cost_hourly`, `cost_monthly` (wholesale USD)
- `source_instance_id` (optional FK to source tables)
- `source_instance_id` (FK to `instance_types.id`)
- `active`, `created_at`, `updated_at`
- UNIQUE constraint on (anvil_instance_id, anvil_region_id)
#### anvil_transfer_pricing
- Data transfer pricing per region
- KRW conversion support
### anvil_transfer_pricing
Data transfer pricing per region.
**Columns:**
- `id`, `anvil_region_id` (FK)
- `price_per_gb` (USD), `price_per_gb_krw` (KRW)
- `price_per_gb` (USD)
- `included_tb` (reference only)
- `active`, `created_at`, `updated_at`
- UNIQUE constraint on anvil_region_id
### 2. TypeScript Types (src/types.ts)
## Pricing Sync Flow
Added 8 new type definitions:
Provider sync automatically updates Anvil pricing via `syncAnvilPricing()`.
### Flow Diagram
```
Provider API → pricing table (wholesale USD) → anvil_pricing (retail USD)
↓
syncProvider()
↓
syncAnvilPricing()
↓
retail = wholesale × 1.21
```
### Retail Markup Calculation
```typescript
AnvilRegion
AnvilInstance
AnvilPricing
AnvilTransferPricing
AnvilRegionInput
AnvilInstanceInput
AnvilPricingInput
AnvilTransferPricingInput
// src/constants.ts
export const USD_RETAIL_DEFAULTS = {
MARGIN_MULTIPLIER: 1.1, // 10% margin
VAT_MULTIPLIER: 1.1, // 10% VAT
TOTAL_MULTIPLIER: 1.21, // Combined
};
// Hourly: rounded to 4 decimal places
calculateRetailHourly(0.0075) // → 0.0091
// Monthly: rounded to nearest $1
calculateRetailMonthly(5) // → 6
```
All Input types auto-derive from their base types, excluding `id`, `created_at`, and `updated_at`.
### Source Mapping
`anvil_pricing` links to source data via:
- `source_instance_id` → `instance_types.id`
- `anvil_region_id` → `anvil_regions.source_region_id` → `regions.id`
### 3. Repositories
When sync runs, it:
1. Finds anvil_pricing records with `source_instance_id` set
2. Looks up wholesale price from `pricing` table using source_instance_id + source_region_id
3. Calculates retail price (×1.21)
4. Updates anvil_pricing with new retail prices
Created 4 repository classes following existing BaseRepository pattern:
## API Authentication
#### AnvilRegionsRepository
- `findByName(name: string)` - Find by Anvil region name
- `findByCountry(countryCode: string)` - Get all regions in a country
- `findBySourceRegion(sourceRegionId: number)` - Reverse lookup
- `findActive()` - Get all active regions
- `updateActive(id: number, active: boolean)` - Toggle active status
- `upsertMany(regions: AnvilRegionInput[])` - Bulk insert/update
API key stored in Vault:
```
Path: secret/data/cloud-instances-api
Key: api_key
```
#### AnvilInstancesRepository
- `findByName(name: string)` - Find by instance name
- `findByCategory(category)` - Filter by vm/gpu/g8/vpu
- `findActive(category?)` - Get active instances with optional category filter
- `searchByResources(minVcpus?, minMemoryGb?, minDiskGb?, category?)` - Resource-based search
- `updateActive(id: number, active: boolean)` - Toggle active status
- `upsertMany(instances: AnvilInstanceInput[])` - Bulk insert/update
Set wrangler secret:
```bash
wrangler secret put API_KEY
```
#### AnvilPricingRepository

### 4. Repository Factory Updates
Updated `RepositoryFactory` class to include:
- `anvilRegions: AnvilRegionsRepository`
- `anvilInstances: AnvilInstancesRepository`
- `anvilPricing: AnvilPricingRepository`
- `anvilTransferPricing: AnvilTransferPricingRepository`
All repositories use lazy singleton pattern for efficient caching.
### 5. KRW Pricing Support
Pricing repositories automatically calculate KRW prices using environment variables:
- `KRW_EXCHANGE_RATE` - Base USD to KRW conversion rate (default: 1450)
- `KRW_VAT_RATE` - VAT multiplier (default: 1.1 for 10% VAT)
- `KRW_MARKUP_RATE` - Markup multiplier (default: 1.1 for 10% markup)
KRW prices are auto-calculated during `upsertMany()` operations.

// Returns: anvil-tyo1, anvil-tyo2, anvil-tyo3, anvil-osa1, anvil-osa2
// Get pricing for a region
const pricing = await repos.anvilPricing.findByRegion(regionId);
// Find specific region
const tyo1 = await repos.anvilRegions.findByName('anvil-tyo1');
// Get pricing for an instance
const instancePricing = await repos.anvilPricing.findByInstance(instanceId);
```
### Create Anvil Instance
```typescript
await repos.anvilInstances.create({
name: 'anvil-1g-1c',
display_name: 'Basic 1GB',

# KV-Based Cache Index Implementation
## Overview
Implemented KV-based cache index for `CacheService` to enable pattern-based cache invalidation and enumeration. This resolves the TODO at line 274 in `src/services/cache.ts`.
## Changes Summary
### 1. Core Implementation (`src/services/cache.ts`)
**Constructor Update:**
- Added optional `kvNamespace: KVNamespace | null` parameter
- Defaults to `null` for backward compatibility
- Logs KV index availability on initialization
**New Features:**
- `invalidatePattern(pattern: string): Promise<number>` - Pattern-based cache invalidation with wildcard support
- `clearAll(prefix?: string): Promise<number>` - Actually clears and counts entries when KV is available
- `getStats(): Promise<{ supported: boolean; indexed_keys?: number }>` - Returns actual key count when KV is available
**Private Helper Methods:**
- `_registerCacheKey(key: string, ttlSeconds: number): Promise<void>` - Registers cache keys in KV index
- `_unregisterCacheKey(key: string): Promise<void>` - Unregisters cache keys from KV index
- `_listCacheKeys(prefix?: string): Promise<string[]>` - Lists all cache keys from KV index
**Key Design Decisions:**
- **KV Index Prefix**: `cache_index:` to separate from rate limiting data
- **Auto-Expiration**: KV entries use same TTL as cache entries (automatic cleanup)
- **Graceful Degradation**: All KV operations are non-blocking, failures are logged but don't break cache operations
- **Backward Compatibility**: Works with or without KV namespace, existing code unchanged
### 2. Route Updates
**`src/routes/instances.ts`:**
- Updated `getCacheService()` to accept `env: Env` parameter
- Passes `env.RATE_LIMIT_KV` to CacheService constructor
- Enables KV index for all instance cache operations
**`src/routes/recommend.ts`:**
- Updated `getCacheService()` to accept `env: Env` parameter
- Passes `env.RATE_LIMIT_KV` to CacheService constructor
- Enables KV index for all recommendation cache operations
### 3. Test Coverage (`src/services/cache-kv.test.ts`)
**24 comprehensive tests:**
- Cache key registration/unregistration
- Pattern invalidation with wildcards
- clearAll() with and without KV
- Error handling and graceful degradation
- Backward compatibility (no KV)
- Large-scale operations (150 keys)
**Test Results:**
```
✓ 24 tests passed (24)
Duration: 26ms
```
## API Changes
### Pattern Invalidation
**Before:**
```typescript
async invalidatePattern(pattern: string): Promise<void> {
logger.warn(`Pattern invalidation not supported: ${pattern}`);
// TODO: Implement with KV-based cache index if needed
}
```
**After:**
```typescript
async invalidatePattern(pattern: string): Promise<number> {
// Returns count of invalidated entries
// Supports wildcards: *, case-insensitive
// Examples:
// '*instances*' - All instance caches
// '*provider=linode*' - All linode caches
// '*pricing*' - All pricing caches
}
```
### clearAll() Enhancement
**Before:**
```typescript
async clearAll(prefix?: string): Promise<number> {
logger.info('Cache clearAll requested', { prefix });
return 0; // Always returns 0
}
```
**After:**
```typescript
async clearAll(prefix?: string): Promise<number> {
// Returns actual count of cleared entries when KV is available
// Returns 0 when KV is not available (backward compatible)
}
```
### getStats() Enhancement
**Before:**
```typescript
async getStats(): Promise<{ supported: boolean }> {
return { supported: false };
}
```
**After:**
```typescript
async getStats(): Promise<{ supported: boolean; indexed_keys?: number }> {
// Returns indexed_keys count when KV is available
// Returns { supported: false } when KV is not available
}
```
## Usage Examples
### With KV Index (Production)
```typescript
import { Env } from './types';
import { CacheService } from './services/cache';
import { CACHE_TTL } from './constants';
// Initialize with KV namespace for full functionality
const cache = new CacheService(CACHE_TTL.INSTANCES, env.RATE_LIMIT_KV);
// Set cache entries
await cache.set('https://cache.internal/instances?provider=linode', instancesData);
await cache.set('https://cache.internal/instances?provider=vultr', vultrData);
await cache.set('https://cache.internal/pricing?provider=linode', pricingData);
// Pattern invalidation (wildcard support)
const count = await cache.invalidatePattern('*instances*');
console.log(`Invalidated ${count} instance cache entries`);
// Clear all caches
const cleared = await cache.clearAll();
console.log(`Cleared ${cleared} total cache entries`);
// Clear with prefix filter
const clearedInstances = await cache.clearAll('https://cache.internal/instances');
console.log(`Cleared ${clearedInstances} instance cache entries`);
// Get statistics
const stats = await cache.getStats();
console.log(`Cache has ${stats.indexed_keys} indexed keys`);
```
### Without KV Index (Development/Backward Compatible)
```typescript
// Initialize without KV namespace (backward compatible)
const cache = new CacheService(CACHE_TTL.INSTANCES);
// Basic cache operations work normally
await cache.set('key', data);
const result = await cache.get<MyType>('key');
// Pattern invalidation returns 0 (logs warning)
const invalidated = await cache.invalidatePattern('*pattern*');
// → Returns 0, logs warning
// clearAll returns 0 (logs info)
const cleared = await cache.clearAll();
// → Returns 0, logs info
// Stats indicate not supported
const stats = await cache.getStats();
// → { supported: false }
```
## KV Index Structure
**Index Key Format:**
```
cache_index:{original_cache_key}
```
**Example:**
```
cache_index:https://cache.internal/instances?provider=linode
```
**KV Entry Metadata:**
```typescript
{
cached_at: "2026-01-25T15:00:00.000Z",
ttl: 300
}
```
**Auto-Cleanup:**
- KV entries use same TTL as cache entries
- KV automatically deletes expired entries
- No manual cleanup required
## Pattern Matching
**Wildcard Support:**
- `*` matches any characters
- Case-insensitive matching
- Regex special characters are properly escaped
**Examples:**
```typescript
// Match all instance caches
invalidatePattern('*instances*');
// Match specific provider
invalidatePattern('*provider=linode*');
// Match specific endpoint
invalidatePattern('https://cache.internal/pricing*');
// Match exact pattern
invalidatePattern('*instances?provider=vultr*');
```
## Performance Characteristics
**With KV Index:**
- `set()`: +1 KV write (async, non-blocking)
- `delete()`: +1 KV delete (async, non-blocking)
- `clearAll()`: 1 KV list + N cache deletes + N KV deletes
- `invalidatePattern()`: 1 KV list + N cache deletes + N KV deletes
- `getStats()`: 1 KV list operation
**Without KV Index:**
- All operations identical to original implementation
- No performance overhead
**Graceful Degradation:**
- KV failures don't break cache operations
- Errors are logged but not thrown
- Cache operations continue normally
## Migration Guide
### For Existing Code (No Changes Required)
Existing code continues to work without changes:
```typescript
// This still works (no KV index)
const cache = new CacheService(CACHE_TTL.INSTANCES);
```
### For New Features (Enable KV Index)
To enable pattern invalidation and enumeration:
```typescript
// Pass KV namespace as second parameter
const cache = new CacheService(CACHE_TTL.INSTANCES, env.RATE_LIMIT_KV);
```
### Production Deployment
**Option 1: Reuse RATE_LIMIT_KV (Current Implementation)**
- No configuration changes required
- Cache index data stored in same KV as rate limiting
- Prefix separation prevents conflicts (`cache_index:` vs `ratelimit:`)
**Option 2: Dedicated CACHE_INDEX_KV (Future Enhancement)**
- Add new KV namespace in wrangler.toml:
```toml
[[kv_namespaces]]
binding = "CACHE_INDEX_KV"
id = "your-kv-id-here"
```
- Update routes to use `env.CACHE_INDEX_KV` instead of `env.RATE_LIMIT_KV`
## Testing
**Run all cache tests:**
```bash
npm run test -- cache-kv.test.ts
```
**Coverage:**
- 24 unit tests
- All edge cases covered
- Error handling validated
- Backward compatibility verified
## Security Considerations
- KV index only stores cache keys (not data)
- Same security as rate limiting KV
- No sensitive data exposure
- Automatic cleanup via TTL expiration
## Benefits
1. **Pattern Invalidation**: Invalidate multiple cache entries at once
2. **Accurate Counts**: `clearAll()` now returns actual count
3. **Cache Statistics**: Monitor cache usage and size
4. **Backward Compatible**: Works with or without KV
5. **Automatic Cleanup**: KV TTL keeps index clean
6. **Graceful Degradation**: KV failures don't break cache operations
## Known Limitations
- KV eventual consistency: Recent writes may not appear immediately in list operations
- Pattern matching is done in-memory after KV list (not server-side)
- Large cache sizes (>1000 keys) may require pagination handling
- KV list operations have ~100ms latency

# Cache Service - KV Index Usage Guide
## Quick Start
### Initialization
**With KV Index (Recommended):**
```typescript
import { CacheService } from './services/cache';
import { CACHE_TTL } from './constants';
const cache = new CacheService(CACHE_TTL.INSTANCES, env.RATE_LIMIT_KV);
```
**Without KV Index (Backward Compatible):**
```typescript
const cache = new CacheService(CACHE_TTL.INSTANCES);
```
## Common Operations
### Pattern-Based Invalidation
```typescript
// Invalidate all instance caches
const count = await cache.invalidatePattern('*instances*');
console.log(`Invalidated ${count} entries`);
// Invalidate specific provider caches
await cache.invalidatePattern('*provider=linode*');
// Invalidate pricing caches
await cache.invalidatePattern('*pricing*');
// Invalidate with exact pattern
await cache.invalidatePattern('https://cache.internal/instances?provider=vultr*');
```
### Clear All Caches
```typescript
// Clear all cache entries
const totalCleared = await cache.clearAll();
// Clear with prefix filter
const instancesCleared = await cache.clearAll('https://cache.internal/instances');
```
### Cache Statistics
```typescript
const stats = await cache.getStats();
if (stats.supported) {
console.log(`Cache has ${stats.indexed_keys} entries`);
} else {
console.log('KV index not available');
}
```
## Use Cases
### After Data Sync
```typescript
// Clear all cached instance data after sync
const invalidated = await cache.invalidatePattern('*instances*');
logger.info(`Invalidated ${invalidated} instance cache entries after sync`);
```
### Provider-Specific Updates
```typescript
// Update only Linode data, invalidate Linode caches
await syncLinodeData();
await cache.invalidatePattern('*provider=linode*');
```
### Cache Cleanup
```typescript
// Daily cache cleanup (optional, caches auto-expire)
const cleared = await cache.clearAll();
logger.info(`Cache cleanup: ${cleared} entries cleared`);
```
## Pattern Syntax
**Wildcards:**
- `*` - Matches any characters
- Case-insensitive by default
**Examples:**
```typescript
// Match all
'*'
// Match endpoint
'*instances*'
'*pricing*'
// Match specific parameter
'*provider=linode*'
'*region_code=us-east*'
// Match exact URL
'https://cache.internal/instances?provider=linode'
// Match with prefix
'https://cache.internal/instances*'
```
## Performance
**Operation Costs:**
- `invalidatePattern()`: 1 KV list + N cache deletes + N KV deletes
- `clearAll()`: 1 KV list + N cache deletes + N KV deletes
- `getStats()`: 1 KV list
**KV List Performance:**
- ~100ms for <1000 keys
- Pagination handled automatically
- Results cached during operation
## Error Handling
All KV operations use graceful degradation:
```typescript
// KV failures don't break cache operations
await cache.set(key, data); // Succeeds even if KV registration fails
await cache.delete(key); // Succeeds even if KV unregistration fails
// Pattern operations return 0 on KV failures
const count = await cache.invalidatePattern('*pattern*');
// Returns 0 if KV list fails, logs error
```
## Monitoring
**Log Levels:**
- `DEBUG`: Cache hits/misses, KV operations
- `INFO`: Pattern invalidation results, clear operations
- `WARN`: KV not available, unsupported operations
- `ERROR`: KV failures (non-blocking)
**Key Metrics:**
```typescript
const stats = await cache.getStats();
// { supported: true, indexed_keys: 42 }
```
## Best Practices
1. **Enable KV Index in Production**: Pass `env.RATE_LIMIT_KV` for full functionality
2. **Use Pattern Invalidation**: Prefer `invalidatePattern()` over individual `delete()` calls
3. **Monitor Stats**: Use `getStats()` to track cache size
4. **Prefix Organization**: Use consistent URL prefixes for easy filtering
5. **Handle Failures**: Always check return values from invalidation operations
## Limitations
- **KV Eventual Consistency**: Recent writes may not appear immediately in list operations
- **Pattern Matching**: Done in-memory after KV list (not server-side)
- **Large Caches**: >1000 keys may have higher latency for pattern operations
- **No Dedicated Namespace**: Currently reuses RATE_LIMIT_KV (future: add CACHE_INDEX_KV)
## Future Enhancements
- Dedicated `CACHE_INDEX_KV` namespace
- Server-side pattern filtering
- Batch invalidation optimization
- Cache warming strategies
- Advanced statistics (hit rate, size, etc.)

## Migration Files
## Automated Migration System
The project uses an **automated migration tracking system** that:
- ✅ Automatically detects and runs unapplied migrations
- ✅ Tracks migration history in the database
- ✅ Executes migrations in numerical order
- ✅ Safe to run multiple times (idempotent)
- ✅ Records execution time and errors
### Quick Start
```bash
# Check migration status
npm run db:migrate:status
# Run all pending migrations (local)
npm run db:migrate
# Run all pending migrations (remote)
npm run db:migrate:remote
```
### Migration Files
All migration files are named with a numeric prefix for ordering:
- `000_migration_history.sql` - Creates migration tracking table (always runs first)
- `002_add_composite_indexes.sql` - Query performance optimization
- `003_add_retail_pricing.sql` - Add retail pricing columns
- `004_anvil_tables.sql` - Anvil-branded product tables
## Migration Details
### 000_migration_history.sql
**Date**: 2026-01-25
**Purpose**: Create migration tracking system
- Creates `migration_history` table to track applied migrations
- Records execution time, success/failure status, and error messages

### 003_add_retail_pricing.sql
**Date**: 2026-01-23
**Purpose**: Add retail pricing fields to all pricing tables
- Adds `hourly_price_retail` and `monthly_price_retail` columns
- Backfills existing data with 1.21x markup
### 004_anvil_tables.sql
**Date**: 2026-01-25
**Purpose**: Create Anvil-branded product tables
- `anvil_regions` - Anvil regional datacenters
- `anvil_instances` - Anvil instance specifications
- `anvil_pricing` - Anvil retail pricing with cost tracking
- `anvil_transfer_pricing` - Data transfer pricing
## Running Migrations
### Local Development
### Automated (Recommended)
```bash
npm run db:migrate
# Check current status
npm run db:migrate:status # Local database
npm run db:migrate:status:remote # Remote database
# Run all pending migrations
npm run db:migrate # Local database
npm run db:migrate:remote # Remote database
```
### Production
### Manual (Backward Compatibility)
Individual migration scripts are still available:
```bash
npm run db:migrate:remote
npm run db:migrate:002 # Local
npm run db:migrate:002:remote # Remote
npm run db:migrate:003 # Local
npm run db:migrate:003:remote # Remote
npm run db:migrate:004 # Local
npm run db:migrate:004:remote # Remote

# Vault Connector
TypeScript client for HashiCorp Vault integration in Cloudflare Workers.
## Features
- **Secure Credential Retrieval**: Fetch provider API credentials from Vault
- **Automatic Caching**: 1-hour TTL in-memory cache to reduce API calls
- **Comprehensive Error Handling**: Type-safe error handling with specific error codes
- **Timeout Protection**: 10-second request timeout with abort controller
- **Type Safety**: Full TypeScript support with strict typing
- **Logging**: Structured logging for debugging and monitoring
## Installation
The VaultClient is part of this project. Import it directly:
```typescript
import { VaultClient, VaultError } from './connectors/vault';
```
## Quick Start
### Basic Usage
```typescript
import { VaultClient } from './connectors/vault';
const vault = new VaultClient(
'https://vault.anvil.it.com',
'hvs.your-token-here'
);
// Retrieve credentials
const credentials = await vault.getCredentials('linode');
// Use credentials for API calls (DO NOT log sensitive data)
```
### Cloudflare Workers Integration
```typescript
export default {
async fetch(request: Request, env: Env) {
const vault = new VaultClient(env.VAULT_URL, env.VAULT_TOKEN);
try {
const creds = await vault.getCredentials('linode');
// Use credentials for API calls
} catch (error) {
if (error instanceof VaultError) {
return new Response(error.message, {
status: error.statusCode || 500
});
}
}
}
};
```
## API Reference
### VaultClient
#### Constructor
```typescript
new VaultClient(baseUrl: string, token: string)
```
**Parameters:**
- `baseUrl`: Vault server URL (e.g., `https://vault.anvil.it.com`)
- `token`: Vault authentication token (e.g., `hvs.gvtS2U0TCnGkVXlfBP7MGddi`)
#### Methods
##### `getCredentials(provider: string): Promise<VaultCredentials>`
Retrieve credentials for a provider from Vault.
**Parameters:**
- `provider`: Provider name (`linode`, `vultr`, `aws`)
**Returns:**
```typescript
{
provider: string;
api_token: string;
}
```
**Throws:**
- `VaultError` on authentication, authorization, or network failures
**Example:**
```typescript
const creds = await vault.getCredentials('linode');
```
##### `clearCache(provider?: string): void`
Clear cached credentials.
**Parameters:**
- `provider` (optional): Specific provider to clear, or omit to clear all
**Example:**
```typescript
// Clear specific provider
vault.clearCache('linode');
// Clear all cache
vault.clearCache();
```
##### `getCacheStats(): { size: number; providers: string[] }`
Get current cache statistics.
**Returns:**
```typescript
{
size: number; // Number of cached providers
providers: string[]; // List of cached provider names
}
```
**Example:**
```typescript
const stats = vault.getCacheStats();
console.log(`Cached: ${stats.size} providers`);
```
### VaultError
Custom error class for Vault operations.
**Properties:**
```typescript
{
name: 'VaultError';
message: string;
statusCode?: number; // HTTP status code
provider?: string; // Provider name that caused error
}
```
## Error Handling
### HTTP Status Codes
| Code | Meaning | Action |
|------|---------|--------|
| 401 | Invalid/expired token | Check authentication token |
| 403 | Insufficient permissions | Verify token has access to provider path |
| 404 | Provider not found | Check provider name spelling |
| 500-503 | Server error | Retry request after delay |
| 504 | Timeout | Check network connectivity |
### Error Handling Pattern
```typescript
try {
const creds = await vault.getCredentials('linode');
} catch (error) {
if (error instanceof VaultError) {
switch (error.statusCode) {
case 401:
console.error('Auth failed:', error.message);
break;
case 403:
console.error('Permission denied:', error.message);
break;
case 404:
console.error('Provider not found:', error.provider);
break;
default:
console.error('Vault error:', error.message);
}
} else {
console.error('Unexpected error:', error);
}
}
```
## Caching
### Cache Behavior
- **TTL**: 1 hour (3600 seconds)
- **Storage**: In-memory (Map)
- **Automatic**: Transparent caching on first request
- **Cache Hit**: Subsequent requests within TTL use cached data
- **Cache Miss**: Expired or cleared entries fetch from Vault
### Cache Example
```typescript
const vault = new VaultClient(url, token);
// First call - fetches from Vault
const creds1 = await vault.getCredentials('linode');
console.log('[VaultClient] Cache miss, fetching from Vault');
// Second call - uses cache (no API call)
const creds2 = await vault.getCredentials('linode');
console.log('[VaultClient] Cache hit');
// Check cache
const stats = vault.getCacheStats();
console.log(`Cached: ${stats.providers.join(', ')}`);
// Manual cache clear
vault.clearCache('linode');
```
## Configuration
### Environment Variables
Store Vault configuration in environment variables for security:
```toml
# wrangler.toml
[vars]
VAULT_URL = "https://vault.anvil.it.com"
[[env.production.vars]]
VAULT_TOKEN = "hvs.production-token"
[[env.development.vars]]
VAULT_TOKEN = "hvs.development-token"
```
### Usage with Environment Variables
```typescript
export default {
async fetch(request: Request, env: Env) {
const vault = new VaultClient(env.VAULT_URL, env.VAULT_TOKEN);
// ...
}
};
```
## Vault Server Configuration
### Secret Path Structure
Credentials are stored at:
```
secret/data/{provider}
```
Example paths:
- `secret/data/linode`
- `secret/data/vultr`
- `secret/data/aws`
### Expected Secret Format
```json
{
"data": {
"data": {
"provider": "linode",
"api_token": "your-api-token-here"
},
"metadata": {
"created_time": "2024-01-21T10:00:00Z",
"version": 1
}
}
}
```
### Required Vault Permissions
Your token must have read access to the secret paths:
```hcl
path "secret/data/linode" {
capabilities = ["read"]
}
path "secret/data/vultr" {
capabilities = ["read"]
}
path "secret/data/aws" {
capabilities = ["read"]
}
```
## Performance
### Request Timeout
- Default: 10 seconds
- Implemented via `AbortController`
- Throws `VaultError` with status code 504 on timeout
### Cache Performance
- **Cache Hit**: <1ms (memory lookup)
- **Cache Miss**: ~100-500ms (network request + parsing)
- **Memory Usage**: ~1KB per cached provider
### Optimization Tips
1. **Parallel Requests**: Fetch multiple providers in parallel
```typescript
const [linode, vultr] = await Promise.all([
vault.getCredentials('linode'),
vault.getCredentials('vultr'),
]);
```
2. **Warm Cache**: Preload frequently used providers
```typescript
// Warm cache at worker startup
await Promise.all([
vault.getCredentials('linode'),
vault.getCredentials('vultr'),
]);
```
3. **Monitor Cache**: Track cache hit rate
```typescript
const stats = vault.getCacheStats();
console.log(`Cache efficiency: ${stats.size} providers cached`);
```
## Testing
Comprehensive test suite included:
```bash
npm test vault.test.ts
```
**Test Coverage:**
- ✅ Constructor initialization
- ✅ Successful credential retrieval
- ✅ Caching behavior
- ✅ HTTP error handling (401, 403, 404, 500)
- ✅ Timeout handling
- ✅ Invalid response structure
- ✅ Missing required fields
- ✅ Network errors
- ✅ Cache management
- ✅ VaultError creation
## Logging
Structured logging for debugging:
```
[VaultClient] Initialized { baseUrl: 'https://vault.anvil.it.com' }
[VaultClient] Retrieving credentials { provider: 'linode' }
[VaultClient] Cache miss, fetching from Vault { provider: 'linode' }
[VaultClient] Credentials cached { provider: 'linode', expiresIn: '3600s' }
[VaultClient] Credentials retrieved successfully { provider: 'linode' }
```
Error logging:
```
[VaultClient] HTTP error { provider: 'linode', statusCode: 401, errorMessage: 'permission denied' }
[VaultClient] Unexpected error { provider: 'linode', error: Error(...) }
```
## Examples
See [vault.example.ts](/Users/kaffa/cloud-server/src/connectors/vault.example.ts) for comprehensive usage examples:
- Basic usage
- Environment variables
- Caching demonstration
- Cache management
- Error handling patterns
- Cloudflare Workers integration
- Parallel provider fetching
- Retry logic
## Security Best Practices
1. **Never commit tokens**: Use environment variables
2. **Rotate tokens regularly**: Update tokens periodically
3. **Use least privilege**: Grant only required Vault permissions
4. **Monitor access**: Track Vault access logs
5. **Secure transmission**: Always use HTTPS
6. **Cache clearing**: Clear cache on token rotation
## Troubleshooting
### Common Issues
#### Authentication Failed (401)
**Problem**: Invalid or expired Vault token
**Solution**:
```typescript
// Verify token format
console.log('Token:', env.VAULT_TOKEN);
// Should start with 'hvs.'
```
#### Permission Denied (403)
**Problem**: Token lacks read access to provider path
**Solution**: Update Vault policy to grant read access
#### Provider Not Found (404)
**Problem**: Provider doesn't exist in Vault
**Solution**: Verify provider name and path in Vault
#### Request Timeout (504)
**Problem**: Network connectivity or slow Vault response
**Solution**:
- Check network connectivity
- Verify Vault server is responsive
- Consider increasing timeout (requires code modification)
#### Invalid Response Structure
**Problem**: Vault response format doesn't match expected structure
**Solution**: Verify Vault secret format matches documentation

# Linode Connector
TypeScript client for Linode API integration in Cloudflare Workers.
## Features
- **Complete API Coverage**: Fetch regions and instance types
- **Rate Limiting**: Automatic compliance with Linode's 1600 requests/hour limit
- **Data Normalization**: Transform Linode data to standardized database format
- **Comprehensive Error Handling**: Type-safe error handling with specific codes
- **Vault Integration**: Secure credential management via VaultClient
- **Timeout Protection**: 10-second request timeout with abort controller
- **Type Safety**: Full TypeScript support with strict typing
- **Logging**: Structured logging for debugging and monitoring
## Installation
The LinodeConnector is part of this project. Import it directly:
```typescript
import { LinodeConnector, LinodeError } from './connectors/linode';
import { VaultClient } from './connectors/vault';
```
## Quick Start
### Basic Usage
```typescript
import { VaultClient } from './connectors/vault';
import { LinodeConnector } from './connectors/linode';
const vault = new VaultClient(
'https://vault.anvil.it.com',
'hvs.your-token-here'
);
const connector = new LinodeConnector(vault);
// Initialize (fetches credentials from Vault)
await connector.initialize();
// Fetch regions
const regions = await connector.fetchRegions();
// Fetch instance types
const instances = await connector.fetchInstanceTypes();
```
### Data Normalization
```typescript
const providerId = 1; // Database provider ID
// Normalize regions for database storage
const normalizedRegions = regions.map(region =>
connector.normalizeRegion(region, providerId)
);
// Normalize instance types for database storage
const normalizedInstances = instances.map(instance =>
connector.normalizeInstance(instance, providerId)
);
```
## API Reference
### LinodeConnector
#### Constructor
```typescript
new LinodeConnector(vaultClient: VaultClient)
```
**Parameters:**
- `vaultClient`: Initialized VaultClient instance for credential retrieval
#### Properties
```typescript
readonly provider = 'linode';
```
#### Methods
##### `initialize(): Promise<void>`
Initialize connector by fetching credentials from Vault. **Must be called before making API requests.**
**Throws:**
- `LinodeError` on Vault or credential loading failures
**Example:**
```typescript
await connector.initialize();
```
##### `fetchRegions(): Promise<LinodeRegion[]>`
Fetch all regions from Linode API.
**Returns:**
- Array of raw Linode region data
**Throws:**
- `LinodeError` on API failures
**Example:**
```typescript
const regions = await connector.fetchRegions();
console.log(`Fetched ${regions.length} regions`);
```
##### `fetchInstanceTypes(): Promise<LinodeInstanceType[]>`
Fetch all instance types from Linode API.
**Returns:**
- Array of raw Linode instance type data
**Throws:**
- `LinodeError` on API failures
**Example:**
```typescript
const instances = await connector.fetchInstanceTypes();
console.log(`Fetched ${instances.length} instance types`);
```
##### `normalizeRegion(raw: LinodeRegion, providerId: number): RegionInput`
Normalize Linode region data for database storage.
**Parameters:**
- `raw`: Raw Linode region data
- `providerId`: Database provider ID
**Returns:**
- Normalized region data ready for insertion
**Example:**
```typescript
const normalized = connector.normalizeRegion(rawRegion, 1);
```
**Normalization Details:**
- `region_code`: Linode region ID (e.g., "us-east")
- `region_name`: Human-readable name (e.g., "Newark, NJ")
- `country_code`: ISO 3166-1 alpha-2 lowercase
- `latitude/longitude`: Not provided by Linode (set to null)
- `available`: 1 if status is "ok", 0 otherwise
##### `normalizeInstance(raw: LinodeInstanceType, providerId: number): InstanceTypeInput`
Normalize Linode instance type data for database storage.
**Parameters:**
- `raw`: Raw Linode instance type data
- `providerId`: Database provider ID
**Returns:**
- Normalized instance type data ready for insertion
**Example:**
```typescript
const normalized = connector.normalizeInstance(rawInstance, 1);
```
**Normalization Details:**
- `memory_mb`: Already in MB (no conversion)
- `storage_gb`: Converted from MB to GB (divide by 1024)
- `transfer_tb`: Converted from GB to TB (divide by 1000)
- `network_speed_gbps`: Converted from Mbps to Gbps (divide by 1000)
- `gpu_type`: Set to "nvidia" if GPUs > 0
- `instance_family`: Mapped from Linode class (see mapping below)
### LinodeError
Custom error class for Linode operations.
**Properties:**
```typescript
{
name: 'LinodeError';
message: string;
statusCode?: number; // HTTP status code
details?: unknown; // Additional error details from API
}
```
## Instance Family Mapping
Linode instance classes are mapped to standardized families:
| Linode Class | Instance Family | Description |
|--------------|----------------|-------------|
| `nanode` | `general` | Entry-level shared instances |
| `standard` | `general` | Standard shared instances |
| `highmem` | `memory` | High-memory optimized instances |
| `dedicated` | `compute` | Dedicated CPU instances |
| `gpu` | `gpu` | GPU-accelerated instances |
| Unknown | `general` | Default fallback |
## Rate Limiting
### Linode API Limits
- **Rate Limit**: 1600 requests per hour
- **Requests Per Second**: ~0.44 (calculated from hourly limit)
- **Implementation**: Conservative 0.4 requests/second
### How It Works
The connector automatically throttles requests to comply with Linode's rate limits:
```typescript
// These requests are automatically rate-limited
await connector.fetchRegions(); // Request 1 at 0ms
await connector.fetchInstanceTypes(); // Request 2 at 2500ms
await connector.fetchRegions(); // Request 3 at 5000ms
```
**Benefits:**
- No manual rate limiting required
- Prevents 429 "Too Many Requests" errors
- Ensures API access remains available
- Transparent to the caller
## Error Handling
### HTTP Status Codes
| Code | Meaning | Action |
|------|---------|--------|
| 401 | Invalid/expired token | Check API token in Vault |
| 403 | Insufficient permissions | Verify token scope |
| 429 | Rate limit exceeded | Wait and retry (should not occur with rate limiter) |
| 500-599 | Server error | Retry request after delay |
| 504 | Timeout | Check network connectivity |
### Error Handling Pattern
```typescript
try {
await connector.initialize();
const regions = await connector.fetchRegions();
} catch (error) {
if (error instanceof LinodeError) {
switch (error.statusCode) {
case 401:
console.error('Auth failed:', error.message);
// Check Vault credentials
break;
case 403:
console.error('Permission denied:', error.message);
// Verify token permissions
break;
case 429:
console.error('Rate limit exceeded:', error.message);
// Should not occur with rate limiter, but handle gracefully
break;
case 504:
console.error('Timeout:', error.message);
// Check network or retry
break;
default:
console.error('Linode error:', error.message);
console.error('Details:', error.details);
}
} else {
console.error('Unexpected error:', error);
}
}
```
## Cloudflare Workers Integration
### Complete Example
```typescript
import { VaultClient } from './connectors/vault';
import { LinodeConnector, LinodeError } from './connectors/linode';
import type { Env } from './types';
export default {
async fetch(request: Request, env: Env) {
const vault = new VaultClient(env.VAULT_URL, env.VAULT_TOKEN);
const connector = new LinodeConnector(vault);
try {
// Initialize
await connector.initialize();
// Fetch data in parallel
const [regions, instances] = await Promise.all([
connector.fetchRegions(),
connector.fetchInstanceTypes(),
]);
// Normalize data
const providerId = 1;
const normalizedData = {
regions: regions.map(r => connector.normalizeRegion(r, providerId)),
instances: instances.map(i => connector.normalizeInstance(i, providerId)),
};
return new Response(JSON.stringify({
success: true,
data: normalizedData,
}), {
status: 200,
headers: { 'Content-Type': 'application/json' },
});
} catch (error) {
if (error instanceof LinodeError) {
return new Response(JSON.stringify({
success: false,
error: error.message,
}), {
status: error.statusCode || 500,
headers: { 'Content-Type': 'application/json' },
});
}
return new Response('Internal server error', { status: 500 });
}
}
};
```
## Vault Configuration
### Secret Path
Linode credentials are stored at:
```
secret/data/linode
```
### Expected Secret Format
```json
{
"data": {
"data": {
"provider": "linode",
"api_token": "your-linode-api-token-here"
},
"metadata": {
"created_time": "2024-01-21T10:00:00Z",
"version": 1
}
}
}
```
### Required Vault Permissions
```hcl
path "secret/data/linode" {
capabilities = ["read"]
}
```
## API Response Examples
### Region Response
```json
{
"data": [
{
"id": "us-east",
"label": "Newark, NJ",
"country": "us",
"capabilities": ["Linodes", "Block Storage"],
"status": "ok"
}
]
}
```
### Instance Type Response
```json
{
"data": [
{
"id": "g6-nanode-1",
"label": "Nanode 1GB",
"price": {
"hourly": 0.0075,
"monthly": 5.0
},
"memory": 1024,
"vcpus": 1,
"disk": 25600,
"transfer": 1000,
"network_out": 1000,
"gpus": 0,
"class": "nanode"
}
]
}
```
## Performance
### Request Timing
- **Rate Limiter**: ~2.5 seconds between requests (0.4 req/s)
- **API Response**: ~100-500ms per request
- **Timeout**: 10 seconds maximum per request
### Optimization Tips
1. **Parallel Initialization**: Warm Vault cache during startup
```typescript
// Pre-load credentials during worker startup
await connector.initialize();
```
2. **Batch Processing**: Process normalized data in batches
```typescript
const normalizedRegions = regions.map(r =>
connector.normalizeRegion(r, providerId)
);
```
3. **Error Recovery**: Implement retry logic for transient failures
```typescript
async function fetchWithRetry(fn: () => Promise<any>, retries = 3) {
for (let i = 0; i < retries; i++) {
try {
return await fn();
} catch (error) {
if (i === retries - 1) throw error;
await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)));
}
}
}
```
## Logging
Structured logging for debugging:
```
[LinodeConnector] Initialized
[LinodeConnector] Fetching credentials from Vault
[LinodeConnector] Credentials loaded successfully
[LinodeConnector] Fetching regions
[LinodeConnector] Making request { endpoint: '/regions' }
[LinodeConnector] Regions fetched { count: 25 }
[LinodeConnector] Fetching instance types
[LinodeConnector] Making request { endpoint: '/linode/types' }
[LinodeConnector] Instance types fetched { count: 50 }
```
Error logging:
```
[LinodeConnector] HTTP error { statusCode: 401, errorMessage: 'Invalid token' }
[LinodeConnector] Request timeout { endpoint: '/regions', timeout: 10000 }
[LinodeConnector] Unexpected error { endpoint: '/regions', error: Error(...) }
```
## Examples
See [linode.example.ts](/Users/kaffa/cloud-server/src/connectors/linode.example.ts) for comprehensive usage examples:
- Basic usage
- Data normalization
- Error handling patterns
- Cloudflare Workers integration
- Rate limiting demonstration
- Instance family mapping
## Security Best Practices
1. **Never commit tokens**: Store API tokens in Vault
2. **Rotate tokens regularly**: Update tokens periodically
3. **Use least privilege**: Grant only required API permissions
4. **Monitor access**: Track API usage and rate limits
5. **Secure transmission**: Always use HTTPS
6. **Cache credentials**: VaultClient handles credential caching
## Troubleshooting
### Connector Not Initialized
**Problem**: "Connector not initialized" error
**Solution**: Call `initialize()` before making API requests
```typescript
await connector.initialize();
```
### Rate Limit Exceeded (429)
**Problem**: Too many requests error
**Solution**: Should not occur with rate limiter, but if it does:
- Check if multiple connector instances are being used
- Verify rate limiter is functioning correctly
- Add additional delay between requests if needed
### Request Timeout (504)
**Problem**: Requests timing out after 10 seconds
**Solution**:
- Check network connectivity
- Verify Linode API status
- Consider increasing timeout (requires code modification)
### Invalid Instance Family
**Problem**: Warning about unknown instance class
**Solution**: Update `mapInstanceFamily()` method with new class mapping

*
* KNOWN LIMITATIONS:
*
* 1. EVENTUAL CONSISTENCY: KV writes are eventually consistent, which may

* This is acceptable for abuse prevention.
*
* 2. RACE CONDITIONS: Multiple concurrent requests may all succeed if they
* read before any writes complete. This is acceptable - rate limiting
* provides statistical protection, not strict guarantees.
*
* For strict rate limiting requirements (billing, quotas), consider:
* - Cloudflare Durable Objects for atomic counters with strong consistency
* - Cloudflare's built-in Rate Limiting rules for global enforcement
*
* This implementation is suitable for abuse prevention with single KV read
* per request (30-50ms overhead).

* Post-sync invalidation:
* - After sync operation, call cache.delete(key) for all relevant keys
* - Verify next request fetches fresh data from database
*
* Test 9: clearAll Method
* -----------------------
* 1. Set multiple cache entries:
* - await cache.set('key1', { data: 'test1' }, 300)
* - await cache.set('key2', { data: 'test2' }, 300)
* - await cache.set('key3', { data: 'test3' }, 300)
* 2. Call clearAll: const count = await cache.clearAll()
* 3. Expected: count === 0 (enumeration not supported)
* 4. Expected: Log message about TTL-based expiration
* 5. Note: Individual entries will expire based on TTL
*
* Test 10: clearAll with Prefix
* ------------------------------
* 1. Set entries with different prefixes:
* - await cache.set('https://cache.internal/instances?foo=bar', data1)
* - await cache.set('https://cache.internal/pricing?foo=bar', data2)
* 2. Call with prefix: await cache.clearAll('https://cache.internal/instances')
* 3. Expected: count === 0, log shows prefix parameter
* 4. Note: Prefix is logged but enumeration not supported by Cache API
*
* Test 11: clearByEndpoint Method
* --------------------------------
* 1. Set endpoint cache: await cache.set('https://cache.internal/instances', data, 300)
* 2. Clear by endpoint: const deleted = await cache.clearByEndpoint('instances')
* 3. Expected: deleted === true if cache entry existed
* 4. Get data: const result = await cache.get('https://cache.internal/instances')
* 5. Expected: result === null (entry deleted)
* 6. Note: Only exact matches deleted, parameterized queries remain cached
*
* Test 12: clearByEndpoint with Non-existent Endpoint
* ----------------------------------------------------
* 1. Clear non-existent: const deleted = await cache.clearByEndpoint('non-existent')
* 2. Expected: deleted === false
* 3. Expected: Log message about non-existent endpoint
*
* Test 13: Cache Invalidation Strategy
* -------------------------------------
* 1. Set parameterized cache entries:
* - cache.generateKey({ provider: 'linode', region: 'us-east' })
* - cache.generateKey({ provider: 'linode', region: 'eu-west' })
* - cache.generateKey({ provider: 'vultr', region: 'us-east' })
* 2. After schema change or full sync, call clearAll()
* 3. Verify entries expire based on TTL
* 4. For production: Consider using KV-backed cache index for enumeration
*
* Test 14: Error Handling in clearAll
* ------------------------------------
* 1. Mock cache.delete to throw error
* 2. Call clearAll: await cache.clearAll()
* 3. Expected: Error is logged and re-thrown
* 4. Verify error message includes context
*
* Test 15: Error Handling in clearByEndpoint
* -------------------------------------------
* 1. Mock cache.delete to throw error
