## Install
```console
$ npm i @libp2p/webrtc
```
### Browser `<script>` tag
Loading this module through a script tag will make it's exports available as `Libp2pWebrtc` in the global namespace.
```html
<script src="https://unpkg.com/@libp2p/webrtc/dist/index.min.js">
```
## Usage
```js
import { createLibp2p } from 'libp2p'
import { noise } from '@chainsafe/libp2p-noise'
import { multiaddr } from '@multiformats/multiaddr'
import first from 'it-first'
import { pipe } from 'it-pipe'
import { fromString, toString } from 'uint8arrays'
import { webRTC } from '@libp2p/webrtc'
const node = await createLibp2p({
transports: [webRTC()],
connectionEncryption: [noise()],
});
await node.start()
const ma = multiaddr('/ip4/0.0.0.0/udp/56093/webrtc/certhash/uEiByaEfNSLBexWBNFZy_QB1vAKEj7JAXDizRs4_SnTflsQ')
const stream = await node.dialProtocol(ma, ['/my-protocol/1.0.0'])
const message = `Hello js-libp2p-webrtc\n`
const response = await pipe([fromString(message)], stream, async (source) => await first(source))
const responseDecoded = toString(response.slice(0, response.length))
```
## Examples
Examples can be found in the [examples folder](examples/README.md).
## Interfaces
### Transport
Browsers can usually only `dial`, but `listen` is supported in the WebRTC
transport when paired with another listener like CircuitV2, where you listen on
a relayed connection. Take a look at [index.js](examples/browser-to-browser/index.js) for
an example.
### Connection
```js
interface MultiaddrConnection extends Duplex {
close: (err?: Error) => Promise
remoteAddr: Multiaddr
timeline: MultiaddrConnectionTimeline
}
class WebRTCMultiaddrConnection implements MultiaddrConnection { }
```
## Development
Contributions are welcome! The libp2p implementation in JavaScript is a work in progress. As such, there's a few things you can do right now to help out:
- [Check out the existing issues](//github.com/little-bear-labs/js-libp2p-webrtc/issues).
- **Perform code reviews**.
- **Add tests**. There can never be enough tests.
- 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.
Please be aware that all interactions related to libp2p are subject to the IPFS [Code of Conduct](https://github.com/ipfs/community/blob/master/code-of-conduct.md).
Small note: If editing the README, please conform to the [standard-readme](https://github.com/RichardLitt/standard-readme) specification.
This module leans heavily on (Aegir)\[] for most of the `package.json` scripts.
### Build
The build script is a wrapper to `aegir build`. To build this package:
```shell
npm run build
```
The build will be located in the `/dist` folder.
### Protocol Buffers
There is also `npm run generate:proto` script that uses protoc to populate the generated code directory `proto_ts` based on `*.proto` files in src. Don't forget to run this step before `build` any time you make a change to any of the `*.proto` files.
### Test
To run all tests:
```shell
npm test
```
To run tests for Chrome only:
```shell
npm run test:chrome
```
To run tests for Firefox only:
```shell
npm run test:firefox
```
### Lint
Aegir is also used to lint the code, which follows the [Standard](https://github.com/standard/standard) JS linter.
The VS Code plugin for this standard is located at .
To lint this repo:
```shell
npm run lint
```
You can also auto-fix when applicable:
```shell
npm run lint:fix
```
### Clean
```shell
npm run clean
```
### Check Dependencies
```shell
npm run deps-check
```
