          command: npm test
      - run:
          name: Build application
          command: npm run build

workflows:
  version: 2
  build-test-deploy:
    jobs:
      - build-and-test

5. Azure DevOps - Enterprise Integration 🏢

Azure DevOps provides comprehensive tools for enterprise-scale development.

  displayName: 'Install Node.js'

- script: |
    npm install
    npm run build
  displayName: 'npm install and build'

- task: PublishBuildArtifacts@1
  inputs:
    pathtoPublish: 'dist'
    artifactName: 'drop'

6. Travis CI - Simplicity First 🎯

Travis CI remains popular for open-source projects due to its simplicity.

# Example .travis.yml
language: node_js
node_js:
  - 16
  - 18
  - 20

cache:
  directories:
    - node_modules

install:
  - npm ci

script:
  - npm run test
  - npm run build

deploy:
  provider: pages
  skip_cleanup: true
  github_token: $GITHUB_TOKEN
  on:
    branch: main

7. TeamCity - Performance at Scale 🚄

TeamCity by JetBrains offers powerful features for large-scale projects.

// Example TeamCity Kotlin DSL
version = "2024.1"

project {
    buildType {
        id("Build")
        name = "Build"

        steps {
            script {
                name = "Install dependencies"
                scriptContent = "npm install"
            }
            script {
                name = "Run tests"
                scriptContent = "npm test"
            }
            script {
                name = "Build"
                scriptContent = "npm run build"
            }
        }

        triggers {
            vcs {
                branchFilter = "+:*"
            }
        }
    }
}

Choosing the Right Tool 🤔

Consider these factors when selecting a CI/CD tool:

1. Team Size and Expertise

# Small Team Example (GitHub Actions)
name: Simple CI/CD
on: [push]
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: npm ci && npm test

2. Project Scale

// Large Project Example (Jenkins)
pipeline {
    agent any
    stages {
        stage('Build') {
            parallel {
                stage('Frontend') { steps { /* ... */ } }
                stage('Backend') { steps { /* ... */ } }
                stage('Mobile') { steps { /* ... */ } }
            }
        }
    }
}

3. Budget Considerations

# Cost-Effective Setup (Self-hosted Runner)
runs-on: self-hosted
steps:
  - uses: actions/checkout@v3
  - name: Build
    run: |
      docker build -t myapp .
      docker push myapp

Best Practices for CI/CD Implementation 📚

1. Pipeline as Code

# Version controlled pipeline
version: 2.1
workflows:
  version: 2
  build-test-deploy:
    jobs:
      - build
      - test:
          requires:
            - build
      - deploy:
          requires:
            - test

2. Environment Management

# Separate configurations per environment
├── environments/
│   ├── development.env
│   ├── staging.env
│   └── production.env

3. Security Best Practices

# Secure secret management
secrets:
  - name: API_KEY
    valueFrom:
      secretKeyRef:
        name: app-secrets
        key: api-key

Conclusion

Choosing the right CI/CD tool can significantly impact your development workflow. Consider:

• Team size and expertise
• Project requirements
• Integration needs
• Scaling requirements
• Budget constraints

Remember, the best tool is the one that fits your specific needs and helps your team deliver better software faster! 🚀
