OpenAsar

Open-source alternative of Discord desktop's app.asar OpenAsar is currently made of ~80% own code, with the rest being from Discord as it hasn't been rewritten yet or because of compatibility reasons.

Goals

• Hotpluggable - just swap the asar file, nothing else needed
• Lightweight - currently improving startup times ~2x (up to ~4x with experimental config)
• No Tracking - no crash reporting or error tracking (in normal Discord)
• Minimal - generally only doing what is needed
• Patch Platform - provide a platform for future patching

Implementation

Below is a list in order of priority, marked as complete when finished:

• Bootstrapping
• Splash screen
• Error handling
• A bunch of specific minor fixes / features
  • Handle hardware acceleration
  • Add Discord-specific Electron flags?
• Auto start
• First run
• Self-write some small parts of internals
• Patch updater to survive host updates
• Self-write updater code (currently mostly copied)
• Compatibility / replication of original Discord splash?

Custom Patches

Custom patches are another main goal of OpenAsar, patching enhancements where otherwise impossible to do so with traditional mods. Our current ideas for patches to do:

• Skipping checking for updates on startup
• Linux host app updating

Install Guide

OpenAsar is heavily disrecommened due to it being in early development.

1. Download latest release
2. Backup your original app.asar (rename to app.asar.backup / etc)
3. Install OpenAsar app.asar into the original path

Config

You can configure OpenAsar via settings.json (found in your Discord app data / user data), under a openasar object. Keep in mind most options are defaults for good reason, they may temporarily brick your client until you revert your changes. The avaliable options are:

• quickstart (bool) - enables Quickstart (experimental)
• skipStartupUpdateChecks (bool) - skips startup update checking (Linux-only)

An example of a settings.json with OpenAsar config:

{
  "BACKGROUND_COLOR": "#202225",
  "IS_MAXIMIZED": false,
  "IS_MINIMIZED": false,
  "WINDOW_BOUNDS": {
    "x": 801,
    "y": 22,
    "width": 797,
    "height": 876
  },
  "MINIMIZE_TO_TRAY": false,
  "OPEN_ON_STARTUP": false,
  "openasar": {
    "quickstart": true
  }
}
