## 2025-07-29 - 4.2.1 - fix(client)
|
||||||
|
Fix socket hanging issues and add auto-drain feature
|
||||||
|
|
||||||
|
**Fixes:**
|
||||||
|
- Fixed socket hanging issues caused by unconsumed response bodies

||||||
|
- Resolved test timeout problems where sockets remained open after tests completed
|
||||||
|
|
||||||
|
**Features:**
|
||||||
|
- Added automatic response body draining to prevent socket pool exhaustion
|
||||||
|
- Made auto-drain configurable via `autoDrain()` method (enabled by default)
|
||||||
|
- Added logging when auto-drain activates for debugging purposes
|
||||||
|
|
||||||
|
**Improvements:**
|
||||||
|
- Updated all tests to properly consume response bodies
|
||||||
|
- Enhanced documentation about the importance of consuming response bodies
|
||||||
|
|
||||||
|
## 2025-07-29 - 4.2.0 - feat(client)
|
||||||
|

|
||||||
|
|
||||||
|
**Features:**
|
||||||
|
- Added `handle429Backoff()` method to SmartRequest class for automatic HTTP 429 handling
|
||||||
|
- Respects `Retry-After` headers with support for both seconds and HTTP date formats
|
||||||

|
||||||
|
- Optional callback for monitoring rate limit events
|
||||||
|
- Maximum wait time capping to prevent excessive delays
|
||||||
|
|
||||||
|
**Improvements:**
|
||||||
|
- Updated test endpoints to use more reliable services (jsonplaceholder, echo.zuplo.io)
|
||||||
|
- Added timeout parameter to test script for better CI/CD compatibility
|
||||||
|
|
||||||
|
**Documentation:**
|
||||||
|
- Added comprehensive rate limiting section to README with examples
|
||||||
|
- Documented all configuration options for handle429Backoff
|
||||||
|
|
||||||
|
## 2025-07-29 - 4.1.0 - feat(client)
|
||||||
|

|
||||||
|
|
||||||
|
**Features:**
|
||||||
|
- Added `options()` method to SmartRequest class for setting arbitrary request options
|
||||||
|
- Enables setting keepAlive and other platform-specific options via fluent API
|
||||||
|
- Added test coverage for keepAlive functionality
|
||||||
|
|
||||||
|
**Documentation:**

### Setting Request Options
|
||||||
|
|
||||||
|
Use the `options()` method to set any request options supported by the underlying implementation:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import { SmartRequest } from '@push.rocks/smartrequest';
|
||||||
|
|
||||||
|
// Set various options
|
||||||
|
const response = await SmartRequest.create()
|
||||||
|
.url('https://api.example.com/data')
|
||||||
|
.options({
|
||||||
|
keepAlive: true, // Enable connection reuse (Node.js)
|
||||||
|
timeout: 10000, // 10 second timeout
|
||||||
|
hardDataCuttingTimeout: 15000, // 15 second hard timeout
|
||||||
|
// Platform-specific options are also supported
|
||||||
|
})
|
||||||
|
.get();
|
||||||
|
```

|
### Important: Always Consume Response Bodies
|
||||||
|
|
||||||
|
**You should always consume response bodies, even if you don't need the data.** Unconsumed response bodies can cause:
|
||||||
|
- Memory leaks as data accumulates in buffers
|
||||||
|
- Socket hanging with keep-alive connections
|
||||||
|
- Connection pool exhaustion
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// ❌ BAD - Response body is not consumed
|
||||||
|
const response = await SmartRequest.create()
|
||||||
|
.url('https://api.example.com/status')
|
||||||
|
.get();
|
||||||
|
|
||||||
|
if (response.ok) {
|
||||||
|
console.log('Success!');
|
||||||
|
}
|
||||||
|
// Socket may hang here!
|
||||||
|
|
||||||
|
// ✅ GOOD - Response body is consumed
|
||||||
|
const response = await SmartRequest.create()
|
||||||
|
.url('https://api.example.com/status')
|
||||||
|
.get();
|
||||||
|
|
||||||
|
if (response.ok) {
|
||||||
|
console.log('Success!');
|
||||||
|
}
|
||||||
|
await response.text(); // Consume the body even if not needed
|
||||||
|
```
|
||||||
|
|
||||||
|
In Node.js, SmartRequest automatically drains unconsumed responses to prevent socket hanging, but it's still best practice to explicitly consume response bodies. When auto-drain occurs, you'll see a console log: `Auto-draining unconsumed response body for [URL] (status: [STATUS])`.
|
||||||
|
|
||||||
|
You can disable auto-drain if needed:
|
||||||
|
```typescript
|
||||||
|
// Disable auto-drain (not recommended unless you have specific requirements)
|
||||||
|
const response = await SmartRequest.create()
|
||||||
|
.url('https://api.example.com/data')
|
||||||
|
.autoDrain(false) // Disable auto-drain
|
||||||
|
.get();
|
||||||
|
|
||||||
|
// Now you MUST consume the body or the socket will hang
|
||||||
|
await response.text();
|
||||||
|
```

### Rate Limiting (429 Too Many Requests) Handling
|
||||||
|
|
||||||
|
The library includes built-in support for handling HTTP 429 (Too Many Requests) responses with intelligent backoff:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import { SmartRequest } from '@push.rocks/smartrequest';
|
||||||
|
|
||||||
|
// Simple usage - handle 429 with defaults
|
||||||
|
async function fetchWithRateLimitHandling() {
|
||||||
|
const response = await SmartRequest.create()
|
||||||
|
.url('https://api.example.com/data')
|
||||||
|
.handle429Backoff() // Automatically retry on 429
|
||||||
|
.get();
|
||||||
|
|
||||||
|
return await response.json();
|
||||||
|
}
|
||||||
|
|
||||||
|
// Advanced usage with custom configuration
|
||||||
|
async function fetchWithCustomRateLimiting() {
|
||||||
|
const response = await SmartRequest.create()
|
||||||
|
.url('https://api.example.com/data')
|
||||||
|
.handle429Backoff({
|
||||||
|
maxRetries: 5, // Try up to 5 times (default: 3)
|
||||||
|
respectRetryAfter: true, // Honor Retry-After header (default: true)
|
||||||
|
maxWaitTime: 30000, // Max 30 seconds wait (default: 60000)
|
||||||
|
fallbackDelay: 2000, // 2s initial delay if no Retry-After (default: 1000)
|
||||||
|
backoffFactor: 2, // Exponential backoff multiplier (default: 2)
|
||||||
|
onRateLimit: (attempt, waitTime) => {
|
||||||
|
console.log(`Rate limited. Attempt ${attempt}, waiting ${waitTime}ms`);
|
||||||
|
}
|
||||||
|
})
|
||||||
|
.get();
|
||||||
|
|
||||||
|
return await response.json();
|
||||||
|
}
|
||||||
|
|
||||||
|
// Example: API client with rate limit handling
|
||||||
|
class RateLimitedApiClient {
|
||||||
|
private async request(path: string) {
|
||||||
|
return SmartRequest.create()
|
||||||
|
.url(`https://api.example.com${path}`)
|
||||||
|
.handle429Backoff({
|
||||||
|
maxRetries: 3,
|
||||||
|
onRateLimit: (attempt, waitTime) => {
|
||||||
|
console.log(`API rate limit hit. Waiting ${waitTime}ms before retry ${attempt}`);
|
||||||
|
}
|
||||||
|
});
|
||||||
|
}
|
||||||
|
|
||||||
|
async fetchData(id: string) {
|
||||||
|
const response = await this.request(`/data/${id}`).get();
|
||||||
|
return response.json();
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
The rate limiting feature:
|
||||||
|
- Automatically detects 429 responses and retries with backoff
|
||||||
|
- Respects the `Retry-After` header when present (supports both seconds and HTTP date formats)
|
||||||
|
- Uses exponential backoff when no `Retry-After` header is provided
|
||||||
|
- Allows custom callbacks for monitoring rate limit events
|
||||||
|
- Caps maximum wait time to prevent excessive delays
