CI Workflow Example

yaml

name: CI

on:

    branches: [main]

jobs:
  lint-and-type-check:
    runs-on: ubuntu-latest
    steps:

          cache: "npm"
      - run: npm ci
      - run: npm run lint
      - run: npm run type-check

  test:
    runs-on: ubuntu-latest
    needs: lint-and-type-check
    steps:

    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"
      - run: npm ci
      - run: npx playwright install --with-deps
      - run: npm run test:e2e

Environment Variables Check

javascript

// scripts/check-env.js
const requiredEnvVars = [
  "NEXT_PUBLIC_SUPABASE_URL",
  "NEXT_PUBLIC_SUPABASE_ANON_KEY",
  "SUPABASE_SERVICE_ROLE_KEY",
];

const missingVars = requiredEnvVars.filter(
  (varName) => !process.env[varName]
);

if (missingVars.length > 0) {
  console.error("Missing environment variables:");
  missingVars.forEach((v) => console.error(`  - ${v}`));
  process.exit(1);
}

console.log("✅ All required environment variables are set");
