React-Native-WebRTC

A WebRTC module for React Native.

Feature Overview

macOS - We don't currently actively support macOS at this time.
Support might return in the future.

Windows - We don't currently support the react-native-windows platform at this time.
Anyone interested in getting the ball rolling? We're open to contributions.

Web - The react-native-webrtc-web-shim project provides a shim for react-native-web support.
Which will allow you to use (almost) the exact same code in your react-native-web project as you would with react-native directly.

Expo - As this module includes native code it is not available in the Expo Go app by default.
However you can get things working via the expo-dev-client library and out-of-tree config-plugins/react-native-webrtc package.

Unified Plan - As of version 106.0.0 Unified Plan is the only supported mode.
Those still in need of Plan B will need to use an older release.

Simulcast - As of version 111.0.0 Simulcast is now possible with ease.
Software encode/decode factories have been enabled by default.

WebRTC Revision

• Currently used revision: M124 (Fishjam fork)
• iOS dependency: FishjamWebRTC — Fishjam's custom WebRTC build with the defer mic permission patch (replaces JitsiWebRTC).
• Supported architectures
  • Android: armeabi-v7a, arm64-v8a, x86, x86_64
  • iOS: arm64, x86_64
  • tvOS: arm64
  • macOS: arm64, x86_64

Maintaining the iOS WebRTC build (FishjamWebRTC)

The iOS side ships against FishjamWebRTC — a CocoaPods pod published from fishjam-cloud/webrtc that wraps a prebuilt WebRTC.xcframework. Source patches live on the fishjam-m124 branch; the podspec and release tooling live on master.

When to cut a new release

Cut a new FishjamWebRTC version when any of the following happens:

• A new patch lands on fishjam-m124 that we need on the client (e.g. another audio_device_ios.mm change, a fix to the network interfaces path, a privacy-manifest update).
• We rebase fishjam-m124 onto a newer jitsi/webrtc tag (e.g. moving from v124.0.2 to v124.0.3).
• A security advisory in upstream WebRTC requires picking up a fix.

You do not need to cut a new FishjamWebRTC for changes that only touch this RN wrapper (ios/**.{h,m,swift}, JS sources). Those ship as a normal @fishjam-cloud/react-native-webrtc npm bump.

Versioning

<upstream-version>.<fishjam-patch-N>, e.g. 124.0.2.1.

• First three parts = the jitsi upstream version the build is patched on top of.
• Fourth part = Fishjam patch counter against that base, starts at 1, increments per release.
• On upstream rebase (e.g. jitsi ships 124.0.3), reset counter: next release is 124.0.3.1.
• Pin with ~> 124.0.2.0 to accept any Fishjam patch on top of jitsi 124.0.2, or pin exact.

How to cut a release

Full runbook (build, tag, GH release, trunk publish, smoke test) lives in fishjam-cloud/webrtc's RELEASING.md on the master branch. TL;DR:

1. On a macOS build host with depot_tools + a fetch webrtc_ios checkout, switch the gclient src/ to fishjam-m124, run gclient sync, then tools_webrtc/ios/build_ios_libs.py --build_config release --arch device:arm64 simulator:arm64 simulator:x64.
2. Validate the patch is in the built binary: strings WebRTC.xcframework/*/WebRTC.framework/WebRTC | grep -c "<unique-string-from-patch>" — every slice must have a non-zero count. (Release builds strip C++ symbols, so use strings, not nm.)
3. Zip the xcframework as FishjamWebRTC.xcframework.zip, tag vX.Y.Z.N on fishjam-m124, push, and gh release create with the zip attached.
4. On master: bump s.version in ios/FishjamWebRTC.podspec to match, commit, push.
5. pod trunk push ios/FishjamWebRTC.podspec --allow-warnings (one-time pod trunk register per identity).

After a new FishjamWebRTC release

Inside this repo:

1. Bump the dependency in FishjamReactNativeWebrtc.podspec: s.dependency 'FishjamWebRTC', '~> X.Y.Z.0' (or pin exact if needed).
2. Bump version in package.json — minor bump if the underlying WebRTC change is user-observable, patch otherwise.
3. Test with cd ios && pod install in a consuming app and exercise the affected behavior end-to-end.
