How to use private npm packages on DO App Platform

I’m trying to run a Node.js app with private packages. These packages are hosted on GitHub packages. I created a personal access token and added a .npmrc file to my repository.


The token is provided my an environment variable.

When building the app on App Platform, I get this error:

backend | 12:18:10 Installing node_modules using yarn
backend | 12:18:11 yarn install v1.22.10
backend | 12:18:11 [1/4] Resolving packages...
backend | 12:18:11 error Couldn't find package "@my-org/my-package" on the "npm" registry.
backend | 12:18:11 info Visit for documentation about this command.

backend | 12:18:11 ERROR: failed to build: exit status 1
backend | 12:18:11  ! Build failed (exit code 7)

Does App Platform not read the .npmrc file? Also why is it using yarn for installing the dependencies? I specifically avoided yarn because of problems with private GitHub packages.

Hey @Salzian I ran into the same issue and what I ended up doing (since the offending package was a Dockerized server) was ensure that I copied all shared packages to the Docker file. That worked for me.

Hi @Salzian!

If a yarn.lock file exists, App Platform will use Yarn. Otherwise, if a package-lock.json file exists, it will use NPM. It seems like Yarn doesn’t read .npmrc files, so that’s why it’s failing trying to pull your private package.
