GitHub Actions

Базовый workflow

name: CI

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

    steps:
      - uses: actions/checkout@v4

Практика

Задание: CI pipeline

Задача: Настрой CI для проекта с тестами.

Решение:

name: CI

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm run lint
      - run: npm test
