# 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`](Agent.md#parameter-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](https://nodejs.org/api/tls.html#tlsconnectoptions-callback).
* **proxyTls** `BuildOptions` (optional) - Options object passed when creating the underlying socket via the connector builder for the proxy server. See [TLS](https://nodejs.org/api/tls.html#tlsconnectoptions-callback).
Examples:
```js
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.
```js
import { ProxyAgent } from 'undici'
const proxyAgent = new ProxyAgent('my.proxy.server')
```
#### Example - Basic Proxy Request with global agent dispatcher
```js
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
```js
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
```js
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
```js
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)`](Agent.md#parameter-agentdispatchoptions).
### `ProxyAgent.request(options[, callback])`
See [`Dispatcher.request(options [, callback])`](Dispatcher.md#dispatcherrequestoptions-callback).
