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
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
$PATH for easy use in subsequent buildpacks.

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
The buildpack tests use Docker to simulate Heroku's Cedar-14 and Heroku-16 containers.
To run the test suite:
Or to just test in cedar or cedar-14:
make test-cedar-14 make test-heroku-16
The tests are run via the vendored shunit2 test framework.
