# 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.

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
}
```

### `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).
