How was CI/CD configured? What exactly did you do, who did you communicate with?

Setting up CI/CD typically involves several stages and collaboration with different teams:

• Tool selection: for example, GitLab CI, Jenkins, GitHub Actions, CircleCI.
• Pipeline configuration: creating scripts for automatic building, testing, and deploying the frontend application.
• Test automation: integrating unit tests, linters, static code analysis.
• Deployment: configuring automatic deployment to staging or production environments.

During the process, I interacted with:

• Backend developers to coordinate API and environment settings.
• DevOps engineers for infrastructure setup and access rights.
• Testers for integrating automated tests.

An example of GitHub Actions configuration for a React application:

name: CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
    - name: Install dependencies
      run: npm install
    - name: Run tests
      run: npm test -- --watchAll=false
    - name: Build
      run: npm run build
    - name: Deploy
      if: github.ref == 'refs/heads/main'
      run: |
        echo "Deploying to production..."
        # deployment commands

Thus, my role was in configuring the pipeline, writing scripts, and coordinating with teams for successful automatic product release.
