Deno 2.2 Improves Dependency Management and Expands Node.js Compatibility
Deno 2.2 enhances Node.js compatibility, improves dependency management, adds OpenTelemetry support, and expands linting and task automation for developers.
http.Agent
instanceThis 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.
Here are some more interesting uses of agent-base

based on the secureEndpoint
property. This agent can be used with both
the http
and https
modules.
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);
});
