Overview
A build system that detects app frameworks and creates runnable images.
Definition
A build system that detects app frameworks and creates runnable images.
Real-world example
A repo with package.json and a start script is detected as Node.js; Nixpacks produces an image with the correct Node version and runs npm run build && npm start.
Common mistake
Missing lockfiles (package-lock.json, pnpm-lock.yaml) causing non-reproducible builds between deploys.
Better-PaaS in practice
Git deploys use Nixpacks by default. If detection fails, override build/start commands or supply a Dockerfile in the repository.
FAQ
Is Nixpacks only relevant to Better-PaaS?
No. Nixpacks appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
