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
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: https://help.github.com/actions/language-and-framework-guides/using-nodejs-with-github-actions
name: CI Pipeline
# trigger build when pushing, or when creating a pull request
on: [push, pull_request]
jobs:
build:
# run build on latest ubuntu
runs-on: ubuntu-latest
steps:
# this will check out the current branch (https://github.com/actions/checkout#Push-a-commit-using-the-built-in-token)
- uses: actions/checkout@v3
# installing Node
- name: Use Node.js 16.16.0
uses: actions/setup-node@v3
with:
# 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
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 Click on the workflow to view detailed results
And Voila, you have a working GitHub Action workflow now.
