# ci

This directory contains scripts used for code-server's continuous integration infrastructure.

Some of these scripts contain more detailed documentation and options
in header comments.

Any file or directory in this subdirectory should be documented here.

- [./ci/lib.sh](./lib.sh)
  - Contains code duplicated across these scripts.

## Publishing a release

Make sure you have `$GITHUB_TOKEN` set and [hub](https://github.com/github/hub) installed.

1. Update the version of code-server and make a PR.
   1. Update in `package.json`
   2. Update in [./doc/install.md](../doc/install.md)
2. GitHub actions will generate the `npm-package`, `release-packages` and `release-images` artifacts.
   1. You do not have to wait for these.
3. Run `yarn release:github-draft` to create a GitHub draft release from the template with
   the updated version.
   1. Summarize the major changes in the release notes and link to the relevant issues.
4. Wait for the artifacts in step 2 to build.
5. Run `yarn release:github-assets` to download the `release-packages` artifact.
   - It will upload them to the draft release.
6. Run some basic sanity tests on one of the released packages.
   - Especially make sure the terminal works fine.
7. Make sure the github release tag is the commit with the artifacts. This is a bug in
   `hub` where uploading assets in step 5 will break the tag.
8. Publish the release and merge the PR.
   1. CI will automatically grab the artifacts and then:
      1. Publish the NPM package from `npm-package`.
      2. Publish the Docker Hub image from `release-images`.
9. Update the AUR package.
   - Instructions on updating the AUR package are at [cdr/code-server-aur](https://github.com/cdr/code-server-aur).
10. Wait for the npm package to be published.
11. Update the homebrew package.
    - Send a pull request to [homebrew-core](https://github.com/Homebrew/homebrew-core) with the URL in the [formula](https://github.com/Homebrew/homebrew-core/blob/master/Formula/code-server.rb) updated.

## build

This directory contains the scripts used to build and release code-server.
You can disable minification by setting `MINIFY=`.

- [./ci/build/build-code-server.sh](./build/build-code-server.sh) (`yarn build`)
