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.
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 vendored version of Node.js to v0.5.8.
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_node 0.5.8
bin/compile in your editor, and change the following lines:
Commit and push the changes to your buildpack to your Github fork, then push your sample app to Heroku to test. You should see:
