NPM private git module on Heroku

Question

I am trying to deploy my app to Heroku however I rely on using some private git repos as modules. I do this for code reuse between projects, e.g. I have a custom logger I us

Answer 1

I was able to setup resolving of Github private repositories in Heroku build via Personal access tokens.

• Generate Github access token here: https://github.com/settings/tokens
• Set access token as Heroku config var: heroku config:set GITHUB_TOKEN= --app your-app-name or via Heroku Dashboard

• Add heroku-prebuild.sh script:

  #!/bin/bash
  if [ "$GITHUB_TOKEN" != "" ]; then
      echo "Detected GITHUB_TOKEN. Setting git config to use the security token" >&1
      git config --global url."https://${GITHUB_TOKEN}@github.com/".insteadOf git@github.com:
  fi
  

• add the prebuild script to package.json:

  "scripts": {
      "heroku-prebuild": "bash heroku-prebuild.sh"
  }
  

For local environment we can also use git config ... or we can add the access token to ~/.netrc file:

machine github.com
  login PASTE_GITHUB_USERNAME_HERE
  password PASTE_GITHUB_TOKEN_HERE

and installing private github repos should work.

npm install OWNER/REPO --save will appear in package.json as: "REPO": "github:OWNER/REPO"

and resolving private repos in Heroku build should also work. optionally you can setup a postbuild script to unset the GITHUB_TOKEN.
