How can I set up continuous integration for my Express.js application?

To set up continuous integration for your Express.js app, you can use tools like GitHub Actions or Travis CI. Would you like a step-by-step guide?

Yes, please provide a step-by-step guide using GitHub Actions.

First, create a .github/workflows directory in your repository. Then, add a YAML file for your workflow. Here's a basic example:

name: CI

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Install dependencies
        run: npm install
      - name: Run tests
        run: npm test

This will run your tests every time you push to the main branch.

What if I want to deploy my app after the tests pass?

You can add a deployment step in your workflow. For example, after the test step, you can add:

      - name: Deploy
        run: npm run deploy

Make sure you have a deploy script defined in your package.json.
