GitHub Action for install npm dependencies with caching without any configuration

Examples

Basic

This example should cover 95% of use cases.

If you use npm ci or yarn --frozen-lockfile on CI to install NPM dependencies - this Action is for you. Simply use it, and your NPM modules will be installed and the folder ~/.npm or ~/.cache/yarn will be cached. Typical use:

name: main
on: [push]
jobs:
  build-and-test:
    runs-on: ubuntu-latest
    name: Build and test
    steps:
      - uses: actions/checkout@v1
      - uses: bahmutov/npm-install@v1
      - run: npm t

See bahmutov/npm-install-action-example npm-install-action-example.

Subfolders

If your repository contains packages in separate folders, install each one separately

repo/
  app1/
    package-lock.json
  app2/
    yarn.json
name: main
on: [push]

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    name: Build and test
    steps:
      - uses: actions/checkout@v1

      - uses: bahmutov/npm-install@v1
        with:
          working-directory: app1
      - uses: bahmutov/npm-install@v1
        with:
          working-directory: app2

      - name: App1 tests
        run: npm t
        working-directory: app1
      - name: Run app2
        run: node .
        working-directory: app2

See npm-install-monorepo-example npm-install-monorepo-example.

You can also specify multiple subfolders in a single action; one subfolder per line.

name: main
on: [push]

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    name: Build and test
    steps:
      - uses: actions/checkout@v1
      - uses: bahmutov/npm-install@v1
        with:
          working-directory: |
            app1
            app2

Use lock file

By default, this action will use a lock file like package-lock.json or yarn.lock. You can set useLockFile: false to use just package.json which might be better for building libraries.

- uses: bahmutov/npm-install@v1
  with:
    useLockFile: false

NPM

If you are writing your own GitHub Action and would like to use this action as a utility function, import it and run it.

const { npmInstallAction } = require('npm-install')
await npmInstallAction()

Debugging

You can see verbose messages from GitHub Actions by setting the following secrets (from Debugging Actions Guide)

ACTIONS_RUNNER_DEBUG: true
ACTIONS_STEP_DEBUG: true

Tip: environment variable ACTIONS_STEP_DEBUG enables debug messages from this action itself, try it first.

Testing

Using Mocha and Sinon.js following the guide How to set up Mocha with Sinon.js. You can find the tests in test folder. In general:

  • all environment inputs are done inside the action, so they can be stubbed and controlled during tests
  • there are separate workflows in .github/workflows that match examples. Each workflow uses this action to install dependencies
