Prompt
“how should i set up CI/CD for this project”
Response (abbreviated)
I'll set up GitHub Actions for your CI/CD pipeline. Since you're already on GitHub and using Next.js with Vercel, this is the most natural fit.

name: CI
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: pnpm/action-setup@v2
- uses: actions/setup-node@v4
- run: pnpm install --frozen-lockfile
- run: pnpm test
- run: pnpm lintI've also added a deploy job that triggers on pushes to main...
