## What it is
Heroku's official classic buildpack for building and deploying Node.js applications on the Heroku platform. It detects a package., selects npm, Yarn, or pnpm based on the lockfile, and installs the configured Node.js version.

## Use cases
- deploy a node.js app to heroku
- build node app with npm ci on heroku
- use pnpm or yarn on heroku
- pin node version via engines field in package.
- heroku buildpack for nodejs monorepo

## When to choose
- deploying Node.js apps to Heroku's classic Cedar generation
- you want automatic Node.js version and package manager detection
- you need a maintained, officially supported buildpack

## When to avoid
- deploying with Docker or to the newer Fir generation of Heroku
- running Node.js outside Heroku or on other PaaS platforms
- you need a cloud-native buildpack or multi-language build pipeline
