Angular Monorepo / Fast CI / Create a CI Workflow

Create a CI Workflow

Use the following command to generate a CI workflow file.

nx generate ci-workflow --ci=github

This generator creates a .github/workflows/ci.yml file that contains a CI pipeline that will run the lint, test, build and e2e tasks for projects that are affected by any given PR. If you would like to also distribute tasks across multiple machines to ensure fast and reliable CI runs, uncomment the nx-cloud start-ci-run line and have the nx affected line run the e2e-ci task instead of e2e.

The key lines in the CI pipeline are:

name: CI
# ...
jobs:
  main:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      # This enables task distribution via Nx Cloud
      # Run this command as early as possible, before dependencies are installed
      # Learn more at https://nx.dev/ci/reference/nx-cloud-cli#npx-nxcloud-startcirun
      # Uncomment this line to enable task distribution
      # - run: npx nx-cloud start-ci-run --distribute-on="3 linux-medium-js" --stop-agents-after="e2e-ci"
      - uses: actions/setup-node@v3
        with:
          node-version: 20
          cache: 'npm'
      - run: npm ci --legacy-peer-deps
      - uses: nrwl/nx-set-shas@v4
      # Nx Affected runs only tasks affected by the changes in this PR/commit. Learn more: https://nx.dev/ci/features/affected
      # When you enable task distribution, run the e2e-ci task instead of e2e
      - run: npx nx affected -t lint test build e2e
