This is a Heroku buildpack for Node.js apps. It uses NPM and SCons.

Example usage:

$ ls
Procfile  package.json  web.js

$ heroku create --stack cedar --buildpack http://github.com/heroku/heroku-buildpack-nodejs.git

$ git push heroku master

The buildpack will detect your app as Node.js if it has the file package.json in the root. It will use NPM to install your dependencies, and vendors a version of the Node.js runtime into your slug. The node_modules directory will be cached between builds to allow for faster NPM install time.

You can specify the versions of Node.js and npm your application requires using package.json

{
  "name": "myapp",
  "engines": {
    "node": ">=0.4.7 <0.7.0",
    "npm": ">=1.0.0"
  }
}

To list the available versions of Node.js and npm, see these manifests:

http://heroku-buildpack-nodejs.s3.amazonaws.com/manifest.nodejs http://heroku-buildpack-nodejs.s3.amazonaws.com/manifest.npm

To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with --buildpack <your-github-url> and push to it.

To change the vendored binaries for Node.js, NPM, and SCons, use the helper scripts in the support/ subdirectory. You'll need an S3-enabled AWS account and a bucket to store your binaries in.

For example, you can change the default version of Node.js to v0.6.7.

First you'll need to build a Heroku-compatible version of Node.js:

$ export AWS_ID=xxx AWS_SECRET=yyy S3_BUCKET=zzz
$ s3 create $S3_BUCKET
$ support/package_nodejs 0.6.7

Open bin/compile in your editor, and change the following lines:

DEFAULT_NODE_VERSION="0.6.7"
S3_BUCKET=zzz

Commit and push the changes to your buildpack to your Github fork, then push your sample app to Heroku to test. You should see:
