The action currently pins every recent CLI to GHCR, which disables the
CLI's registry fallback and leaves image pulls exposed to GHCR
throttling.
Use the installed CLI version to keep the GHCR default for versions
before v2.108.0 and allow fallback for newer versions. Preserve a
caller's explicit registry choice.
## Summary
This PR prepares `supabase/setup-cli` for `v2.0.0`.
The main goal of this release is to simplify the action and modernize
the repo/tooling around a Bun-based implementation, while tightening
workflows, tests, and documentation.
## What Changed
### Action runtime
- switched the action from a Node/compiled `dist` runtime to a Bun-based
composite action
- removed the checked-in `dist/` output entirely
- simplified the action source down to a single runtime file in
`src/main.ts`
- kept the public action interface the same:
- `with.version`
- `outputs.version`
### Tooling
- switched package management and local tooling from npm to Bun
- removed Rollup and the build step
- replaced Jest with Bun’s native test runner
- replaced Prettier with `oxfmt`
- replaced ESLint with `oxlint`
- enabled type-aware/type-check linting with `oxlint-tsgolint`
- simplified TypeScript config to a single `tsconfig.json` extending
`@tsconfig/bun`
### Tests
- moved tests next to the runtime source
- rewrote tests to focus on meaningful user-facing action behavior
- added coverage for:
- default entrypoint execution
- latest version installs
- legacy version installs
- modern pinned version installs
- failure when the installed CLI cannot report a version
- action code coverage is now `100%`
### Workflows
- renamed workflow files for clarity:
- `test.yml` -> `ci.yml`
- `start.yml` -> `e2e.yml`
- updated workflow/job naming so required checks are clean and stable:
- `CI`
- `E2E`
- `CodeQL`
- `Licensed`
- added aggregate PR-facing checks so branch protection does not need
matrix legs
- made CI and E2E skip heavy jobs on draft PRs
- made E2E run automatically on ready PRs and new commits
- simplified CodeQL config by removing the separate config file
- updated action pins to current releases using commit SHAs
- refined Dependabot for Bun-era updates and non-major auto-merge
### Docs
- refreshed `README.md` and `docs/index.md` for the new v2 behavior
- updated examples to use `@v2`
- added a practical example for exporting local Supabase env vars after
`supabase start`
- removed stale references to old local/dev flows
## Breaking / Notable Changes
- the action now runs as a Bun-based composite action instead of a
prebuilt JavaScript action
- no checked-in `dist/` artifacts anymore
- self-hosted runners now need the prerequisites expected by the
composite action path:
- `bash`
- network access to install Bun/dependencies and download the Supabase
CLI
## Validation
Verified locally with:
- `bun run format:check`
- `bun run lint`
- `bun test`
- `bun run ci`
Also updated workflows and branch-protection-friendly check names so PR
validation is cleaner going forward.
## Follow-up
After merge, branch protection should require only:
- `CI`
- `E2E`
- `CodeQL`
- `Licensed`
