PostgREST on Heroku

The best way to build an API, now for Heroku.

Make a git repo with anything in it. The repo is just a pretext to push to Heroku.

Note that the free tier Heroku PostgreSQL addon will not work because it does not support having multiple database roles. Heroku Postgres paid tiers do support multiple database roles though you'll have to create them through Heroku Postgres Credentials.

We recommend spinning up a Postgres database with Amazon RDS. Make sure you create it in the Virginia region because that's where Heroku's dynos are and it will decrease latency between the server and db.

Next install the Heroku Toolbelt and run these commands.

# first set up a new app
heroku apps:create --buildpack

# now fill in the values specific to your database
heroku config:set POSTGREST_VER=
heroku config:set DB_URI=postgres://
heroku config:set DB_SCHEMA=public
heroku config:set DB_ANON_ROLE=postgrest_test
heroku config:set DB_POOL=60

git push heroku master

To determine the best value for DB_POOL ask the database by running this SQL:

show max_connections;
