Koala eca259281a feat: expand emoji/name system with comprehensive animal mapping
- Create shared/names.js as single source of truth for emoji maps, noun
  lists, adjectives, and username generation (215 animal emoji entries)
- Remove duplicated inline lists from popup.js and background.js; both
  now import getAvatarForName / generateUsername from shared/names.js
- Add names.js to the build script sync list so it stays DRY across
  extension builds
- Fix missing cat emoji: CoolCat now correctly resolves to 🐱
- Sort emoji map keys by length at lookup time to prevent substring
  false-matches (e.g. 'caterpillar' before 'cat')

KoalaSync Shared Constants

This directory contains constants and protocol definitions used by both the extension and the server.

Syncing with the Extension

Important

Every time this directory is modified, you must run node scripts/build-extension.js to keep the extension's copy up to date.

Because Browser Extensions (Manifest V3) cannot load files outside their root directory, all files in this directory must be copied to extension/shared/ whenever they are modified. The build script handles this automatically.

Security & Versioning Constants

  • OFFICIAL_SERVER_TOKEN: A 32-byte hex token required to connect to the official relay server.
  • APP_VERSION: The current version of the extension. Automatically injected from the git tag during CI release builds.
  • OFFICIAL_SERVER_URL: The default endpoint for the official KoalaSync relay.
