CI workflow (evanw/esbuild)
The CI workflow from evanw/esbuild, explained and optimized by Latchkey.
- F
- CI health grade
- 40/100
- Health score
- 5
- Jobs per trigger
- 4
- Fixes in the optimized version
In short
- CI health: F (at risk)
- The optimized version below points runs-on at Latchkey managed runners and adds run de-duplication, caching, and job timeouts.
What it does
This is the CI workflow from the evanw/esbuild repository, a real project running GitHub Actions. It is shown here with attribution under its MIT license.
Below, Latchkey shows a faster, safer version produced by its optimization engine.

What changed
- Run on Latchkey managed runners with one line (
runs-on), which apply the fixes below automatically and self-heal transient failures. Each Linux x64 job moves to the Latchkey size matching its vCPU count,latchkey-smallfor a standard 2 vCPU runner; macOS, Windows and arm64 jobs stay as written. - Cancel superseded runs when a branch or PR gets a newer push.
- Cache dependency installs on the setup step so they are served from cache.
- Add a job timeout so a hung step cannot burn hours of runner time.
Left runs-on as written on the esbuild job: matrix.os mixes Linux with macOS and Windows, which Latchkey does not run. Point only the Linux legs at Latchkey, for example with a matrix include entry that sets the runner.
Left runs-on as written on the esbuild-old-deno-version job: matrix.os mixes Linux with Windows, which Latchkey does not run. Point only the Linux legs at Latchkey, for example with a matrix include entry that sets the runner.
1 third-party action is referenced by a movable tag. Pin it to the commit SHA (Latchkey resolves and applies this automatically) so a repointed tag cannot change what runs.
What Latchkey heals here
This workflow has steps that commonly fail on transient issues (network, registries, flaky browsers). On Latchkey managed runners they are detected, retried, and self-healed instead of failing your build:
- Dependency installs
- End-to-end and browser tests
This workflow runs 5 jobs (8 with the matrix expanded) per trigger. 5 of the 8 run on a standard GitHub-hosted Linux x64 runner, which in a private repository bills $0.006 a minute against $0.0025 on latchkey-small, 58% lower; in a public repository like this one they are free. 3 of the 8 run on macOS and Windows, which Latchkey does not offer, so those stay where they are. Estimate the monthly difference with your own run counts.
