CI pipeline setup in Remix - Mini Project: Build & Apply

CI pipeline setup

📖 Scenario: You are working on a Remix web application. To keep your code quality high and avoid errors, you want to set up a Continuous Integration (CI) pipeline. This pipeline will automatically check your code whenever you push changes to your repository.

🎯 Goal: Build a simple CI pipeline configuration file that installs dependencies, runs tests, and reports the results automatically on every code push.

📋 What You'll Learn

Create a YAML file named ci.yml in the .github/workflows directory

Define a job named build that runs on ubuntu-latest

Add steps to check out the code, install Node.js version 20, install dependencies with npm install, and run tests with npm test

Print the test results as the final output

💡 Why This Matters

🌍 Real World

CI pipelines help developers catch errors early by automatically testing code changes before merging them.

💼 Career

Setting up CI pipelines is a key skill for DevOps engineers and developers to ensure code quality and smooth collaboration.

1

Create the initial CI workflow file

Create a file named ci.yml inside the .github/workflows folder. Add the workflow name CI Pipeline and set it to trigger on push events.

Remix

# Create the YAML file with name and trigger
# Your code here

Hint

Start with the workflow name and on keys in YAML format.

2

Add the build job and runner

Add a job named build that runs on the ubuntu-latest runner.

Remix

name: CI Pipeline
on: [push]
jobs:
  # Add the build job here
  # Your code here

Hint

Use jobs: then define build: with runs-on: ubuntu-latest.

3

Add steps to checkout code and install Node.js

Inside the build job, add steps to: 1) check out the repository code using actions/checkout@v3, and 2) set up Node.js version 20 using actions/setup-node@v3.

Remix

name: CI Pipeline
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      # Add checkout step
      # Add Node.js setup step
      # Your code here

Hint

Use - uses: actions/checkout@v3 and - uses: actions/setup-node@v3 with node-version: '20'.

4

Install dependencies and run tests

Add steps to run npm install to install dependencies and npm test to run tests. These should be run commands inside the build job steps. The final step should print the test results.

Remix

name: CI Pipeline
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: '20'
      # Add npm install step
      # Add npm test step
      # Your code here

Hint

Use - run: npm install and - run: npm test as steps.
