I wasn’t able to find anything in the documentation describing this behavior. Is this expected?

@jmcantrell I don't maintain this package, but for anyone else out there that wants to use this package and follow the pattern that Heroku is using, here you go.

Looking at https://devcenter.heroku.com/articles/release-phase#specifying-release-phase-tasks, it looks like Heroku altered the Procfile format to include a specific process that runs only during the release phase on their platform. This breaks the idea behind the Procfile, which includes only long-running processes. If any of those processes exists, all processes exit. Why? So you can fix the reason why the service quit :)

To mimic the Heroku experience, you need to include each process in the Procfile in your command line. Given the following Procfile (which builds off of your example):

release: node release.js
server: node server.js
redis: /usr/bin/env redis-server
mongo: /usr/bin/env mongod

For your example, above, it would look like ./node_modules/.bin/nf start server redis mongo. This command will start your server, redis, and mongo processes and display colorful output in your terminal.

When you want to invoke the release process/command, you would run ./node_modules/.bin/nf run release.

Throw those in your yarn scripts or somewhere convenient.
