CI/CD for Front End

1. Introduction

Continuous Integration (CI) and Continuous Deployment (CD) are essential practices in modern software development, especially for front-end applications. This lesson explores how to implement CI/CD pipelines effectively, focusing on tools and workflows that enhance development speed and quality.

2. Key Concepts

• Continuous Integration (CI): The practice of automatically building and testing code changes to ensure they integrate well into the existing codebase.
• Continuous Deployment (CD): The process of automatically deploying code changes to production after passing CI tests.
• Pipeline: A series of automated processes that code changes go through from commit to deployment.
• Version Control: A system to manage changes to code, commonly using Git.

3. Step-by-Step Process

3.1 Setting Up a CI/CD Pipeline

Follow these steps to set up a CI/CD pipeline for your front-end application:

1. Choose a CI/CD Tool (e.g., GitHub Actions, CircleCI, Jenkins).
2. Set up a Version Control Repository (e.g., GitHub, GitLab).
3. Define Your Build Configuration:

   name: CI/CD Pipeline
   on:
     push:
       branches:
         - main
   jobs:
     build:
       runs-on: ubuntu-latest
       steps:
         - name: Checkout
           uses: actions/checkout@v2
         - name: Install Dependencies
           run: npm install
         - name: Run Tests
           run: npm test
         - name: Build
           run: npm run build
         - name: Deploy
           run: npm run deploy

4. Configure Deployment Settings in Your CI/CD Tool.
5. Test Your Pipeline by Committing Code Changes.

4. Best Practices

• Keep Your Pipeline Fast: Optimize build times by caching dependencies.
• Run Tests Early: Ensure that tests are run before deployment to catch issues early.
• Use Environments: Set up different environments (development, staging, production) to test changes safely.
• Monitor and Log: Implement logging and monitoring to track your deployments and application health.
