Tobius Buildpack: Monorepo

This buildpack converts a subfolder application within a monorepo into the main (Heroku) application.

1. Add .monorepo file
2. Add Buildpack
3. Add $APP_PATH
4. Push to Heroku

This buildpack's detect script expects a .monorepo file to be found in the project's root folder.

[~/yourproject] touch .monorepo
[~/yourproject] git add .monorepo
[~/yourproject] git commit -m 'Support Monorepo Buildpack'
[~/yourproject] git push

Note: The file contents do not matter.

This Monorepo buildpack works by moving the application subfolder up to the root folder level. Since this needs to happen before the application buildpacks are engaged (e.g. Node, Ruby, etc) this buildpack needs to run first.

1. Visit https://dashboard.heroku.com/apps/{YOURAPPNAME}/settings
2. Configure the first buildpack as https://github.com/tobiusventures/tobius-buildpack-monorepo.git

Note: Once you add a custom buildpack Heroku stops guessing which "other" buildpacks to run after so you will have to add them to this screen manually now (after this buildpack).

Since a Monorepo will presumably have more than one subfolder application you need to tell it which one to use.

1. Visit https://dashboard.heroku.com/apps/{YOURAPPNAME}/settings
2. Set the config var APP_PATH to the subfolder application that you want to deploy to this application container.

Example:

├── .monorepo
├── README.md
├── backend
│   ├── Procfile
│   ├── index.js
│   └── package.json
├── nested
|   └── api1
|       ├── Procfile
|       ├── index.js
|       └── package.json
└── frontend
│   ├── Procfile
│   ├── index.js
│   └── package.json

In the above example APP_PATH could be set to backend, nested/api1 or frontend.

Your Monorepo subfolder application is now configured to run inside your Heroku application. Push it as you would any other.
