Example app demonstrating libsignal_protocol_dart and how to boost web performance

signal_protocol_example_app

This is an example project demonstrating how to use MixinNetwork/libsignal_protocol_dart both on mobile devices and on the web without much performance losses.

Fore more information on the issue with web performance, see MixinNetwork/libsignal_protocol_dart#42

How it works

This project uses the following fork & branch:

https://github.com/lemoony/libsignal_protocol_dart/tree/feature/web-support-with-overwrites

The main performance boost comes from using a custom Javascript library (curve25519-js) instead of the Dart implementation shipping with libsignal_protocol_dart. The JS lib will only be used on the web, whereas the dart implementation on all other devices.

The js library resides at web/js. Directory npm holds a minimal webpack compilation setup. If you want to add additional functions that should be callable, perform the following steps:

• Switch to directory npm and run npm install
• Add the function you want to call to npm/src/index.ts
• Run npm run build. This will automatically updated web/js/app.js.
• Add a facade method to lib/signal/javascript_bundler.dart
