GitHub Actions: Setting up CI for a Node project

CI/CD (Continuous Integration/Continuous Delivery/Development) is now an essential part of all kind of software projects. Today I am going to work you through setting up CI/CD with GitHub Actions.

Setting up CI
To use a GitHub action for building your repository at each push (on all branches), all you have to do is to place a YAML file under .github/workflows and commit it with your repo.

mkdir .github
cd .github
mkdir workflows
cd workflows
Enter fullscreen mode Exit fullscreen mode

Inside the created .yml file, Add the following.

# This workflow will do a clean install of node dependencies, build the source code and run tests
# For more information see:

name: CI Pipeline

# trigger build when pushing, or when creating a pull request
on: [push, pull_request]


    # run build on latest ubuntu
    runs-on: ubuntu-latest

    # this will check out the current branch (
    - uses: actions/checkout@v3
    # installing Node
    - name: Use Node.js 16.16.0
      uses: actions/setup-node@v3
        # this will use the latest Node 16 version
        node-version: 16.16.0
    # install dependencies using clean install to avoid package lock updates
    - run: npm ci
    # build the project if necessary
    - run: npm run build --if-present
    # finally run the test
    - run: npm test
Enter fullscreen mode Exit fullscreen mode

What this workflow basically does is,

  • checkout the branch
  • install node (on ubuntu)
  • install the dependencies of your project and build it if necessary
  • finally, run the tests

Comments are added on every line explaining the setup.

After! Commit & push your work and head over to the Actions section of your repo where you can see all executed workflows…

And Voila, you have a working GitHub Action workflow now.
