heroku-buildpack-npmrc-yarn

A Heroku buildpack for overriding the .npmrc file in the build directory with the contents of a config var. Useful for authorizing with npm when installing private packages.

Configure Multiple Buildpacks

Option 1: Heroku CLI or Dashboard

Add the buildpack to your Heroku app either using the CLI or the Heroku dashboard. The heroku-buildpack-npmrc-yarn needs to run before any buildpack using npm. In the following example, it runs before the heroku/nodejs buildpack.

$ heroku buildpacks:set --index 1 https://github.com/anandtripathi5/heroku-buildpack-npmrc-yarn.git
$ heroku buildpacks:add heroku/nodejs

The same example given for the CLI use would have the following .buildpacks file.

$ cat .buildpacks
https://github.com/anandtripathi5/heroku-buildpack-npmrc-yarn.git
https://github.com/heroku/heroku-buildpack-nodejs.git

Configure Config Var

Add the NPMRC config var in Heroku with the contents of your .npmrc file.

 $ heroku config:set GITHUB_TOKEN=<token>
 $ heroku config:set REPO_USER=<token>
