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 create your own buildpack in order to use different versions of Node.js and/or NPM. To change the vendored binaries for Node.js, NPM, and SCons, use the helper scripts in the
You are going to need the following:
- An S3 enabled AWS account to store your binaries in.
- Your application must use NPM to manage dependencies. (See
package.jsonon the Heroku Dev Center).
- Obviously a Heroku user account. Signup is free and instant.
- Fork this buildpack on Github and clone it to somewhere in order to make changes to it
Set the nexessary environment variables in your shell:
$ export AWS_ID="YOUR-AWS-ID" AWS_SECRET="YOUR-AWS-SECRET" S3_BUCKET="YOUR-S3BUCKET-NAME"
Create your S3 bucket (in case it doesn't exist yet):
$ s3 create $S3_BUCKET
Customise your version of Node that you want to use by running
./support/package_nodewith the desired version of Node. The script will compile Node and push the binaries ready onto your S3 bucket:
$ ./support/package_node 0.6.13
bin/compilein your editor, and change the following lines:
- Commit and push the changes to your buildpack to your Github fork
Create a test application that makes use of your custom buildpack and push to it:
$ heroku create --buildpack <your-github-url>
You should see:
