Publishing extensions

Ship your extension to users through a repository.

Package

Run the build script to produce a signed .rextx package. The package embeds your manifest and a checksum that repositories and clients verify on install.

Publish to a repository

Host the package anywhere reachable by URL and add an entry to your repository manifest. To submit to the official repository, open a pull request against the repository index on GitHub — submissions are reviewed for safety and manifest correctness.

Shipping updates

Bump the version in your manifest, rebuild, and update the repository entry. Users see the update in their Extensions tab within the next repository refresh.
