Each body method can only be called once per response, similar to the fetch API.
### 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();
```
