### Browser `<script>` tag

Loading this module through a script tag will make it's exports available as `Libp2pMplex` in the global namespace.

## API

### `const factory = mplex([options])`

Creates a factory that can be used to create new muxers.

`options` is an optional `Object` that may have the following properties:

- `maxMsgSize` - a number that defines how large mplex data messages can be in bytes, if messages are larger than this they will be sent as multiple messages (default: 1048576 - e.g. 1MB)
- `maxUnprocessedMessageQueueSize` - a number that limits the size of the unprocessed input buffer (default: 4194304 - e.g. 4MB)
- `minSendBytes` - if set, message bytes from the current tick will be batched up to this amount before being yielded by the muxer source, unless the next tick begins in which case all available bytes will be yielded
- `maxInboundStreams` - a number that defines how many incoming streams are allowed per connection (default: 1024)
- `maxOutboundStreams` - a number that defines how many outgoing streams are allowed per connection (default: 1024)
- `maxStreamBufferSize` - a number that defines how large the message buffer is allowed to grow (default: 1024 \* 1024 \* 4 - e.g. 4MB)
- `disconnectThreshold` - if `maxInboundStreams` is reached, close the connection if the remote continues trying to open more than this many streams per second (default: 5)

### `const muxer = factory.createStreamMuxer(components, [options])`

Create a new *duplex* stream that can be piped together with a connection in order to allow multiplexed communications.

e.g.

```js
import { mplex } from '@libp2p/mplex'
import { pipe } from 'it-pipe'

// Create a duplex muxer
const muxer = mplex()

// Use the muxer in a pipeline
pipe(conn, muxer, conn) // conn is duplex connection to another peer
```

`options` is an optional `Object` that may have the following properties:

- `onStream` - A function called when receiving a new stream from the remote. e.g.
```js
// Receive a new stream on the muxed connection
const onStream = stream => {
// Read from this stream and write back to it (echo server)
pipe(
stream,
source => (async function * () {
for await (const data of source) yield data
})(),
stream
)
}
const muxer = mplex({ onStream })
// ...
```
**Note:** The `onStream` function can be passed in place of the `options` object. i.e.
```js
mplex(stream => { /* ... */ })
```
- `onStreamEnd` - A function called when a stream ends
```js
// Receive a notification when a stream ends
const onStreamEnd = stream => {
// Manage any tracking changes, etc
}
const muxer = new Mplex({ onStreamEnd })
// ...
```
- `signal` - An [`AbortSignal`](https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal) which can be used to abort the muxer, *including* all of it's multiplexed connections. e.g.
```js
const controller = new AbortController()
const muxer = mplex({ signal: controller.signal })
pipe(conn, muxer, conn)
controller.abort()
```
- `maxMsgSize` - The maximum size in bytes the data field of multiplexed messages may contain (default 1MB)

### `muxer.onStream`

Use this property as an alternative to passing `onStream` as an option to the `Mplex` constructor.

### `muxer.onStreamEnd`

Use this property as an alternative to passing `onStreamEnd` as an option to the `Mplex` constructor.

### `muxer.streams`

Returns an `Array` of streams that are currently open. Closed streams will not be returned.

### `const stream = muxer.newStream([options])`

Initiate a new stream with the remote. Returns a [duplex stream](https://gist.github.com/alanshaw/591dc7dd54e4f99338a347ef568d6ee9#duplex-it).

e.g.

```js
// Create a new stream on the muxed connection
const stream = muxer.newStream()

// Use this new stream like any other duplex stream:
pipe([1, 2, 3], stream, consume)
```

In addition to `sink` and `source` properties, this stream also has the following API, that will **normally *not* be used by stream consumers**.

#### `stream.close()`

Closes the stream for **reading**. If iterating over the source of this stream in a `for await of` loop, it will return (exit the loop) after any buffered data has been consumed.

This function is called automatically by the muxer when it receives a `CLOSE` message from the remote.

The source will return normally, the sink will continue to consume.

#### `stream.abort([err])`

Closes the stream for **reading** *and* **writing**. This should be called when a *local error* has occurred.

Note, if called without an error any buffered data in the source can still be consumed and the stream will end normally.

This will cause a `RESET` message to be sent to the remote, *unless* the sink has already ended.

The sink will return and the source will throw if an error is passed or return normally if not.

#### `stream.reset()`

Closes the stream *immediately* for **reading** *and* **writing**. This should be called when a *remote error* has occurred.

This function is called automatically by the muxer when it receives a `RESET` message from the remote.

The sink will return and the source will throw.

#### `stream.timeline`

Returns an `object` with `close` and `open` times of the stream.

#### `stream.id`

Returns a `string` with an identifier unique to **this** muxer. Identifiers are not unique across muxers.

## Contribute

The libp2p implementation in JavaScript is a work in progress. As such, there are a few things you can do right now to help out:
## API Docs

- Go through the modules and **check out existing issues**. This is especially useful for modules in active development. Some knowledge of IPFS/libp2p may be required, as well as the infrastructure behind it - for instance, you may need to read up on p2p and more complex operations like muxing to be able to help technically.
- **Perform code reviews**. More eyes will help a) speed the project along b) ensure quality and c) reduce possible future bugs.
