Locking to a buildpack version

In production, you frequently want to lock all of your dependencies - including buildpacks - to a specific version. That way, you can regularly update and test them, upgrading with confidence.

First, find the version you want from the list of buildpack versions. Then, specify that version with buildpacks:set:

heroku buildpacks:set https://github.com/heroku/heroku-buildpack-nodejs#v83 -a my-app

If you have trouble upgrading to the latest version of the buildpack, please open a support ticket at help.heroku.com so we can assist.

Chain Node with multiple buildpacks

This buildpack automatically exports node, npm, and any node_modules binaries into the $PATH for easy use in subsequent buildpacks.

Hacking

To make changes to this buildpack, fork it on GitHub. Push up changes to your fork, then create a new Heroku app to test it, or configure an existing app to use your buildpack:

# Create a new Heroku app that uses your buildpack
heroku create --buildpack <your-github-url>

# Configure an existing Heroku app to use your buildpack
heroku buildpacks:set <your-github-url>

# You can also use a git branch!
heroku buildpacks:set <your-github-url>#your-branch

Tests

The buildpack tests use Docker to simulate Heroku's Cedar and Cedar-14 containers.

To run the test suite:

make test

Or to just test in cedar or cedar-14:

make test-cedar-10
make test-cedar-14

The tests are run via the vendored shunit2 test framework.
