Extension.js 2.0.0-beta bannerExtension.js is now officially in beta.This beta stabilizes the features introduced in the alpha release and fixes all known issues with browser compatibility.Version 2.0.0-beta
  • Fix Sass Modules not working in the content script.
  • Add support for Svelte templates.
  • Add preview command.
  • Add universal support for content_scripts (via hard-reload and hot-reload).
  • Fix all known browser issues for Firefox, Edge, and Chrome.
  • Update documentation (this one!)
The beta release focuses on making all existing features stable enough to document and test. We have locked new features until the next stable release. The documentation is now up to date. This is the last beta release before the release candidate.For the next release, we plan to make Extension.js a faster and smaller bundle. It will work both locally and remotely (via pnpm dlx, yarn dlx, and npx).Thanks for reading. Talk soon.Cezar Augusto
