# 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');
console.log(credentials.api_token);
```
### 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

# D1 Repository Layer
TypeScript repository layer for Cloudflare D1 database operations with type safety, error handling, and transaction support.
## Files Structure
```
src/repositories/
├── base.ts - Abstract base repository with CRUD operations
├── providers.ts - Provider management
├── regions.ts - Region management with bulk upsert
├── instances.ts - Instance type management with search
├── pricing.ts - Pricing management with price history
└── index.ts - Export all repositories & factory
```
## Features
- **Type Safety**: Full TypeScript support with proper types from `src/types.ts`
- **Error Handling**: Custom `RepositoryError` with error codes
- **SQL Injection Prevention**: All queries use prepared statements
- **Transaction Support**: Batch operations via D1 batch API
- **Specialized Methods**: Domain-specific queries for each entity
## Usage
### Basic Repository Operations
```typescript
import { RepositoryFactory } from './repositories';
// Initialize factory
const repos = new RepositoryFactory(env.DB);
// Providers
const provider = await repos.providers.findByName('linode');
await repos.providers.updateSyncStatus('linode', 'success');
// Regions
const regions = await repos.regions.findByProvider(1);
await repos.regions.upsertMany(1, regionDataArray);
// Instances
const instances = await repos.instances.findByProvider(1);
const gpuInstances = await repos.instances.findGpuInstances();
await repos.instances.upsertMany(1, instanceDataArray);
// Pricing
const pricing = await repos.pricing.findByInstance(1);
await repos.pricing.upsertMany(pricingDataArray);
const history = await repos.pricing.getPriceHistory(1);
```
### Advanced Search Examples
```typescript
// Search instances by specifications
const results = await repos.instances.search({
providerId: 1,
minVcpu: 4,
maxVcpu: 16,
minMemoryMb: 8192,
family: 'compute',
hasGpu: false
});
// Search pricing by price range
const affordable = await repos.pricing.searchByPriceRange(
0, // minHourly
0.05, // maxHourly
0, // minMonthly
50 // maxMonthly
);
// Find available regions only
const available = await repos.regions.findAvailable(1); // provider 1
```
### Bulk Operations (Upsert)
All repositories support efficient bulk upsert operations using D1 batch API:
```typescript
// Upsert many regions (atomic operation)
const regionCount = await repos.regions.upsertMany(providerId, [
{
provider_id: 1,
region_code: 'us-east',
region_name: 'US East (Newark)',
country_code: 'US',
latitude: 40.7357,
longitude: -74.1724,
available: 1
},
// ... more regions
]);
// Upsert many instance types
const instanceCount = await repos.instances.upsertMany(providerId, [
{
provider_id: 1,
instance_id: 'g6-nanode-1',
instance_name: 'Nanode 1GB',
vcpu: 1,
memory_mb: 1024,
storage_gb: 25,
transfer_tb: 1,
network_speed_gbps: 0.04,
gpu_count: 0,
gpu_type: null,
instance_family: 'general',
metadata: null
},
// ... more instances
]);
// Upsert many pricing records
const pricingCount = await repos.pricing.upsertMany([
{
instance_type_id: 1,
region_id: 1,
hourly_price: 0.0075,
monthly_price: 5.0,
currency: 'USD',
available: 1
},
// ... more pricing
]);
```
## Error Handling
All repository methods throw `RepositoryError` with specific error codes:
```typescript
import { RepositoryError, ErrorCodes } from '../types';
try {
const provider = await repos.providers.findByName('linode');
} catch (error) {
if (error instanceof RepositoryError) {
switch (error.code) {
case ErrorCodes.NOT_FOUND:
console.error('Provider not found');
break;
case ErrorCodes.DUPLICATE:
console.error('Duplicate entry');
break;
case ErrorCodes.DATABASE_ERROR:
console.error('Database error:', error.cause);
break;
case ErrorCodes.TRANSACTION_FAILED:
console.error('Transaction failed:', error.message);
break;
}
}
}
```
## Error Codes
- `NOT_FOUND`: Record not found
- `DUPLICATE`: Unique constraint violation
- `CONSTRAINT_VIOLATION`: Database constraint violation
- `DATABASE_ERROR`: General database error
- `TRANSACTION_FAILED`: Batch operation failed
- `INVALID_INPUT`: Invalid input data
## Base Repository Methods
All repositories inherit these methods from `BaseRepository<T>`:
- `findById(id: number): Promise<T | null>`
- `findAll(options?: PaginationOptions): Promise<T[]>`
- `create(data: Partial<T>): Promise<T>`
- `update(id: number, data: Partial<T>): Promise<T>`
- `delete(id: number): Promise<boolean>`
- `count(): Promise<number>`
- `executeBatch(statements: D1PreparedStatement[]): Promise<D1Result[]>`
## Specialized Repository Methods
### ProvidersRepository
- `findByName(name: string): Promise<Provider | null>`
- `updateSyncStatus(name: string, status, error?): Promise<Provider>`
- `findByStatus(status): Promise<Provider[]>`
- `upsert(data): Promise<Provider>`
### RegionsRepository
- `findByProvider(providerId: number): Promise<Region[]>`
- `findByCode(providerId, code): Promise<Region | null>`
- `upsertMany(providerId, regions[]): Promise<number>`
- `findAvailable(providerId?): Promise<Region[]>`
- `updateAvailability(id, available): Promise<Region>`
### InstancesRepository
- `findByProvider(providerId: number): Promise<InstanceType[]>`
- `findByFamily(family): Promise<InstanceType[]>`
- `findByInstanceId(providerId, instanceId): Promise<InstanceType | null>`
- `upsertMany(providerId, instances[]): Promise<number>`
- `findGpuInstances(providerId?): Promise<InstanceType[]>`
- `search(criteria): Promise<InstanceType[]>`
### PricingRepository
- `findByInstance(instanceTypeId): Promise<Pricing[]>`
- `findByRegion(regionId): Promise<Pricing[]>`
- `findByInstanceAndRegion(instanceTypeId, regionId): Promise<Pricing | null>`
- `upsertMany(pricing[]): Promise<number>`
- `recordPriceHistory(pricingId, hourly, monthly): Promise<void>`
- `getPriceHistory(pricingId, limit?): Promise<PriceHistory[]>`
- `findAvailable(instanceTypeId?, regionId?): Promise<Pricing[]>`
- `searchByPriceRange(minHourly?, maxHourly?, minMonthly?, maxMonthly?): Promise<Pricing[]>`
- `updateAvailability(id, available): Promise<Pricing>`
## Transaction Support
All `upsertMany` operations use D1 batch API for atomic transactions:
```typescript
// All records are inserted/updated atomically
// If any operation fails, the entire batch is rolled back
const count = await repos.regions.upsertMany(providerId, regions);
```
## Price History Tracking
Price history is automatically tracked via database triggers:
```typescript
// Automatic: Triggers record price changes automatically
await repos.pricing.update(1, { hourly_price: 0.01, monthly_price: 7.50 });
// Manual: Explicitly record price history
await repos.pricing.recordPriceHistory(1, 0.01, 7.50);
// Query: Get price history
const history = await repos.pricing.getPriceHistory(1, 10); // last 10 records
```
## Performance Considerations
- All queries use prepared statements for security and performance
- Bulk operations use batch API to minimize round trips
- Indexes are defined in schema.sql for optimal query performance
- Pagination support via `PaginationOptions` for large datasets
## Testing
Run TypeScript compilation check:
```bash
npx tsc --noEmit
```
## Database Schema
See `/Users/kaffa/cloud-server/schema.sql` for complete database schema including:
- Table definitions
- Indexes
- Triggers for automatic timestamps
- Triggers for price history tracking

/**
* Manual Test Instructions for CacheService
*
* Since Cloudflare Workers Cache API is only available in the Workers runtime,
* these tests must be run in a Cloudflare Workers environment or using Miniflare.
*
* Test 1: Basic Cache Operations
* -------------------------------
* 1. Deploy to Cloudflare Workers development environment
* 2. Initialize cache: const cache = new CacheService(300);
* 3. Set data: await cache.set('test-key', { foo: 'bar' }, 60);
* 4. Get data: const result = await cache.get('test-key');
* 5. Expected: result.data.foo === 'bar', cache_age_seconds ≈ 0
*
* Test 2: Cache Key Generation
* -----------------------------
* 1. Generate key: const key = cache.generateKey({ provider: 'linode', region: 'us-east' });
* 2. Expected: key === 'https://cache.internal/instances?provider=linode&region=us-east'
* 3. Verify sorting: cache.generateKey({ z: 1, a: 2 }) should have 'a' before 'z'
*
* Test 3: Cache Miss
* ------------------
* 1. Request non-existent key: const result = await cache.get('non-existent');
* 2. Expected: result === null
*
* Test 4: Cache Expiration
* ------------------------
* 1. Set with short TTL: await cache.set('expire-test', { data: 'test' }, 2);
* 2. Immediate get: await cache.get('expire-test') → should return data
* 3. Wait 3 seconds
* 4. Get again: await cache.get('expire-test') → should return null (expired)
*
* Test 5: Cache Age Tracking
* --------------------------
* 1. Set data: await cache.set('age-test', { data: 'test' }, 300);
* 2. Wait 5 seconds
* 3. Get data: const result = await cache.get('age-test');
* 4. Expected: result.cache_age_seconds ≈ 5
*
* Test 6: Cache Deletion
* ----------------------
* 1. Set data: await cache.set('delete-test', { data: 'test' }, 300);
* 2. Delete: const deleted = await cache.delete('delete-test');
* 3. Expected: deleted === true
* 4. Get data: const result = await cache.get('delete-test');
* 5. Expected: result === null
*
* Test 7: Error Handling (Graceful Degradation)
* ----------------------------------------------
* 1. Test with invalid cache response (manual mock required)
* 2. Expected: No errors thrown, graceful null return
* 3. Verify logs show error message
*
* Test 8: Integration with Instance API
* --------------------------------------
* 1. Create cache instance in instance endpoint handler
* 2. Generate key from query params: cache.generateKey(query)
* 3. Check cache: const cached = await cache.get<InstanceData[]>(key);
* 4. If cache hit: return cached.data with cache metadata
* 5. If cache miss: fetch from database, cache result, return data
* 6. Verify cache hit on second request
*
* Performance Validation:
* -----------------------
* 1. Measure database query time (first request)
* 2. Measure cache hit time (second request)
* 3. Expected: Cache hit 10-50x faster than database query
* 4. Verify cache age increases on subsequent requests
*
* TTL Strategy Validation:
* ------------------------
* Filtered queries (5 min TTL):
* - cache.set(key, data, 300)
* - Verify expires after 5 minutes
*
* Full dataset (1 hour TTL):
* - cache.set(key, data, 3600)
* - Verify expires after 1 hour
*
* Post-sync invalidation:
* - After sync operation, call cache.delete(key) for all relevant keys
* - Verify next request fetches fresh data from database
