Heroku

Example

An example project can be found at https://github.com/grouparoo/app-example. You can deploy this app with the following button:

Getting Started

1. Create a new git repository
   • Do not include an environment file, .env. Your environment variables will be managed by Heroku
   • Include a package.json file which contains your dependencies and commands per the Deployment Guide
   • Include a Procfile which is similar the to the below. Heroku uses Procfiles to define the multiple processes which run for the same application. In the Procfile we use Environment variables to differentiate between our web and worker processes. we also skip using npm as our process runner, and call the grouparoo start command directly.

# in Procfile
web:    WEB_SERVER=true  WORKERS=0  cd node_modules/@grouparoo/core && ./bin/start
worker: WEB_SERVER=false WORKERS=10 cd node_modules/@grouparoo/core && ./bin/start

2. Add the Heroku add-on heroku-postgres via heroku addons:create heroku-postgresql:<PLAN_NAME>. Learn more about the plan options here: https://devcenter.heroku.com/articles/heroku-postgresql. This add-on will set the Environment Variable DATABASE_URL which Grouparoo will automatically use.
3. Add the Heroku add-on heroku-redis via heroku addons:create heroku-redis:<PLAN_NAME>. Learn more about the plan options here: https://devcenter.heroku.com/articles/heroku-redis. This add-on will set the Environment Variable REDIS_URL which Grouparoo will automatically use.
4. Push your git project to Heroku, or configure Heroku to monitor your Github repo for changes automatically

Notes

Grouparoo will source Heroku's PORT variable automatically to bind to the proper variable port.

Grouparoo will automatically build your project (compiling typescript and including your plugins) after any npm install, which Heroku will automatically run, as there is a package.json checked into your git repository.

You can scale the number of web and worker processes with the heroku ps command. Depending on your workload, you may need more of one type of process than another.

You can start with Heroku's free tier and increase your plan sizes as needed.

Heroku will regularly restart/rebuild your dynos. You may at times see "stuck" background task in the resque dashboard. Grouparoo will automatically rescue these jobs and retry them after an hour.
