Class: ProxyAgent

Extends: undici.Dispatcher

A Proxy Agent class that implements the Agent API. It allows the connection through proxy in a simple way.

new ProxyAgent([options])

Arguments:

• options ProxyAgentOptions (required) - It extends the Agent options.

Returns: ProxyAgent

Parameter: ProxyAgentOptions

Extends: AgentOptions

• uri string (required) - It can be passed either by a string or a object containing uri as string.
• token string (optional) - It can be passed by a string of token for authentication.
• auth string (deprecated) - Use token.
• clientFactory (origin: URL, opts: Object) => Dispatcher (optional) - Default: (origin, opts) => new Pool(origin, opts)
• requestTls BuildOptions (optional) - Options object passed when creating the underlying socket via the connector builder for the request. See TLS.
• proxyTls BuildOptions (optional) - Options object passed when creating the underlying socket via the connector builder for the proxy server. See TLS.

Examples:

import { ProxyAgent } from 'undici'

const proxyAgent = new ProxyAgent('my.proxy.server')
// or
const proxyAgent = new ProxyAgent({ uri: 'my.proxy.server' })

Example - Basic ProxyAgent instantiation

This will instantiate the ProxyAgent. It will not do anything until registered as the agent to use with requests.

import { ProxyAgent } from 'undici'

const proxyAgent = new ProxyAgent('my.proxy.server')

Example - Basic Proxy Request with global agent dispatcher

import { setGlobalDispatcher, request, ProxyAgent } from 'undici'

const proxyAgent = new ProxyAgent('my.proxy.server')
setGlobalDispatcher(proxyAgent)

const { statusCode, body } = await request('http://localhost:3000/foo')

console.log('response received', statusCode) // response received 200

for await (const data of body) {
  console.log('data', data.toString('utf8')) // data foo
}

Example - Basic Proxy Request with local agent dispatcher

import { ProxyAgent, request } from 'undici'

const proxyAgent = new ProxyAgent('my.proxy.server')

const {
  statusCode,
  body
} = await request('http://localhost:3000/foo', { dispatcher: proxyAgent })

console.log('response received', statusCode) // response received 200

for await (const data of body) {
  console.log('data', data.toString('utf8')) // data foo
}

Example - Basic Proxy Request with authentication

import { setGlobalDispatcher, request, ProxyAgent } from 'undici';

const proxyAgent = new ProxyAgent({
  uri: 'my.proxy.server',
  // token: 'Bearer xxxx'
  token: `Basic ${Buffer.from('username:password').toString('base64')}`
});
setGlobalDispatcher(proxyAgent);

const { statusCode, body } = await request('http://localhost:3000/foo');

console.log('response received', statusCode); // response received 200

for await (const data of body) {
  console.log('data', data.toString('utf8')); // data foo
}

ProxyAgent.close()

Closes the proxy agent and waits for registered pools and clients to also close before resolving.

Returns: Promise<void>

Example - clean up after tests are complete

import { ProxyAgent, setGlobalDispatcher } from 'undici'

const proxyAgent = new ProxyAgent('my.proxy.server')
setGlobalDispatcher(proxyAgent)

await proxyAgent.close()

ProxyAgent.dispatch(options, handlers)

Implements Agent.dispatch(options, handlers).

ProxyAgent.request(options[, callback])

See Dispatcher.request(options [, callback]).
