Buildpack for Node.js, io.js And Meteor

This is the official Scalingo buildpack for Node.js apps.

Getting Started

See the Getting Started with Node.js on Scalingo tutorial.

Application Requirements

A package.json file must be present in the root (top-level) directory of your app's source code.

The buildpack supports the npm, Yarn, and pnpm package managers, selected by the lockfile present in your app:

• package-lock.json (npm)
• yarn.lock (Yarn)
• pnpm-lock.yaml (pnpm)

If no lockfile is found, npm is used. A lockfile is strongly recommended for reproducible builds.

Configuration

Node.js Version

Specify the Node.js version for your app with the engines.node field in package.json:

{
  "engines": {
    "node": "24.x"
  }
}

We recommend using a major version range (like 24.x) rather than pinning an exact version, so your app automatically receives Node.js security and bug-fix updates.

If you don't specify a version, the buildpack uses the current recommended LTS release.

For the list of supported Node.js versions, see our documentation.
