# Using Dialyzer for type checking
- [Setup with Phoenix](https://github.com/jeremyjh/dialyxir/wiki/Phoenix-Dialyxir-Quickstart)
- Uses [ExGuard](https://github.com/slashmili/ex_guard) to run every time a file is changed.
- Run `mix guard` to start watching files.
- Check out `.exguard.exs` for configuration.

# Postgres setup

# Issues encountered

- Building the client files fails with not enough ram
- It runs out of ram on a Centos vps so I needed to add more swap space

# Battlenet API
Battlenet required https for a redirect for authentication. I use caddy for https proxy during development.

Caddyfile
```
https://localhost {
        tls self_signed
        proxy / http://localhost:8080 {
                transparent
                websocket
        }
}
```
