## Configuration files
## Configuration
Configuration files can either be in YAML or JSON their names are derived from the `GO_ENV` variable, for example `GO_ENV=prod` will cause the `prod.yaml` config file to be used. or `GO_ENV=dev` will use the `dev.yaml`. A path to look for the config files in can be specified using the `-path <folder>` command line argument.

## YugabyteDB
Yugabyte is an open-source, geo-distrubuted cloud-native relational DB that scales horizontally. Super Graph works with Yugabyte right out of the box. If you think you're data needs will outgrow Postgres and you don't really want to deal with sharding then Yugabyte is the way to go. Just point Super Graph to your Yugabyte DB and everything will just work including running migrations, seeding, querying, mutations, etc.
To use Yugabyte in your local development flow just uncomment the following lines in the `docker-compose.yml` file that is part of your Super Graph app. Also remember to comment out the originl postgres `db` config.
```yaml
# Postgres DB
# db:
# image: postgres:latest
# ports:
# - "5432:5432"
#Standard config to run a single node of Yugabyte

## Developing Super Graph
If you want to build and run Super Graph from code then the below commands will build the web ui and launch Super Graph in developer mode with a watcher to rebuild on code changes. And the demo rails app is also launched to make it essier to test changes.
