agent-base
==========
### Turn a function into an [`http.Agent`][http.Agent] instance
This module is a thin wrapper around the base `http.Agent` class.
It provides an abstract class that must define a `connect()` function,
which is responsible for creating the underlying socket that the HTTP
client requests will use.
The `connect()` function may return an arbitrary `Duplex` stream, or
another `http.Agent` instance to delegate the request to, and may be
asynchronous (by defining an `async` function).
Instances of this agent can be used with the `http` and `https`
modules. To differentiate, the options parameter in the `connect()`
function includes a `secureEndpoint` property, which can be checked
to determine what type of socket should be returned.
#### Some subclasses:
Here are some more interesting uses of `agent-base`.
Send a pull request to list yours!
* [`http-proxy-agent`][http-proxy-agent]: An HTTP(s) proxy `http.Agent` implementation for HTTP endpoints
* [`https-proxy-agent`][https-proxy-agent]: An HTTP(s) proxy `http.Agent` implementation for HTTPS endpoints
* [`pac-proxy-agent`][pac-proxy-agent]: A PAC file proxy `http.Agent` implementation for HTTP and HTTPS
* [`socks-proxy-agent`][socks-proxy-agent]: A SOCKS proxy `http.Agent` implementation for HTTP and HTTPS
Example
-------
Here's a minimal example that creates a new `net.Socket` or `tls.Socket`
based on the `secureEndpoint` property. This agent can be used with both
the `http` and `https` modules.
```ts
import * as net from 'net';
import * as tls from 'tls';
import * as http from 'http';
import { Agent } from 'agent-base';
class MyAgent extends Agent {
connect(req, opts) {
// `secureEndpoint` is true when using the "https" module
if (opts.secureEndpoint) {
return tls.connect(opts);
} else {
return net.connect(opts);
}
}
});
// Keep alive enabled means that `connect()` will only be
// invoked when a new connection needs to be created
const agent = new MyAgent({ keepAlive: true });
// Pass the `agent` option when creating the HTTP request
http.get('http://nodejs.org/api/', { agent }, (res) => {
console.log('"response" event!', res.headers);
res.pipe(process.stdout);
});
```
