A WebRTC module for React Native.
- Support iOS / macOS / Android.
- Support Video / Audio / Data Channels.
> 🚨 Expo: This package is not available in the Expo Go app. Learn how you can use this package in Custom Dev Clients via the out-of-tree Expo Config Plugin.
Everyone is welcome to our Discourse community to discuss any React Native and WebRTC related topics.
* Currently used revision: M94
* Supported architectures
* Android: armeabi-v7a, arm64-v8a, x86, x86_64
* iOS: arm64, x86_64 (for bitcode support, run this script)
* macOS: x86_64
index.ios.js/index.android.js, you can require WebRTC to import RTCPeerConnection, RTCSessionDescription, etc.``javascript`
import {
RTCPeerConnection,
RTCIceCandidate,
RTCSessionDescription,
RTCView,
MediaStream,
MediaStreamTrack,
mediaDevices,
registerGlobals
} from 'react-native-webrtc';
Anything about using RTCPeerConnection, RTCSessionDescription and RTCIceCandidate is like browser.
Support most WebRTC APIs, please see the Document.
`javascript
const configuration = {"iceServers": [{"url": "stun:stun.l.google.com:19302"}]};
const pc = new RTCPeerConnection(configuration);
let isFront = true;
mediaDevices.enumerateDevices().then(sourceInfos => {
console.log(sourceInfos);
let videoSourceId;
for (let i = 0; i < sourceInfos.length; i++) {
const sourceInfo = sourceInfos[i];
if(sourceInfo.kind == "videoinput" && sourceInfo.facing == (isFront ? "front" : "environment")) {
videoSourceId = sourceInfo.deviceId;
}
}
mediaDevices.getUserMedia({
audio: true,
video: {
width: 640,
height: 480,
frameRate: 30,
facingMode: (isFront ? "user" : "environment"),
deviceId: videoSourceId
}
})
.then(stream => {
// Got stream!
})
.catch(error => {
// Log error
});
});
pc.createOffer().then(desc => {
pc.setLocalDescription(desc).then(() => {
// Send pc.localDescription to peer
});
});
pc.onicecandidate = function (event) {
// send event.candidate to peer
};
// also support setRemoteDescription, createAnswer, addIceCandidate, onnegotiationneeded, oniceconnectionstatechange, onsignalingstatechange, onaddstream
`
However, render video stream should be used by React way.
Rendering RTCView.
`javascript`
| Name | Type | Default | Description |
| ------------------------------ | ---------------- | ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ |
| mirror | boolean | false | Indicates whether the video specified by "streamURL" should be mirrored during rendering. Commonly, applications choose to mirror theuser-facing camera. |
| objectFit | string | 'contain' | Can be contain or cover |
| streamURL | string | '' | This is mandatory |
| zOrder | number | 0 | Similarly to zIndex |
#### registerGlobals()
By calling this method the JavaScript global namespace gets "polluted" with the following additions:
* navigator.mediaDevices.getUserMedia()
*
*
*
*
*
*
*
This is useful to make existing WebRTC JavaScript libraries (that expect those globals to exist) work with react-native-webrtc.
#### MediaStreamTrack.prototype._switchCamera()
This function allows to switch the front / back cameras in a video track
on the fly, without the need for adding / removing tracks or renegotiating.
#### VideoTrack.enabled
Starting with version 1.67, when setting a local video track's enabled state to
false, the camera will be closed, but the track will remain alive. Settingtrue` will re-enable the camera.
it back to
The react-native-webrtc organization provides a number of packages which are useful when developing Real Time Communications applications.
The react-native-webrtc-web-shim project provides a shim for react-native-web support, allowing you to use (almost) the same code in react-native-web as in react-native.
Thanks to all contributors for helping with the project!
Special thanks to Wan Huang Yang for creating the first version of this package.
