Changeset Status workflow (lit/lit)

The Changeset Status workflow from lit/lit, explained and optimized by Latchkey.

What it does

This is the Changeset Status workflow from the lit/lit repository, a real project running GitHub Actions. It is shown here with attribution under its BSD-3-Clause license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

The workflow

name: Changeset Status

on: [pull_request]

permissions:
  contents: read

jobs:
  # Enforce that all PRs that change packages need changesets. Changes
  # without changesets result in this job failing.
  changeset:
    runs-on: ubuntu-latest
    # Skip if author is lit-robot which means it's a release PR that doesn't
    # need this check.
    if: ${{ github.event.pull_request.user.login != 'lit-robot' }}

What changed

• Run on Latchkey managed runners with one line (runs-on), which apply the fixes below automatically and self-heal transient failures. This example uses latchkey-small; pick the runner size that fits the job.
• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

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

This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
