Configuration File

[0xcaff]

Problem

There are variables which are used to configure the behavior of the program. They should be stored in a centralized location and documented. Here are some of the variables:

• ffmpeg path
• serve bind host

fixture_setup

Currently, dotenv is used for some configuration in fixture setup.

Solutions

• config-rs
• environment variables

toml is easy to use for configs.

There are many different ways to configure an application. I'm against the idea of configuration files because they are state as a file. It is annoying to set settings of a docker container with configuration files. Environment variables are nicer for this. That said, environment variables give up structure. They don't allow for type checking (except at time used). Discoverability is worse.

I think because we have a few, using environment variables (potentially with dotenv) with sane defaults is the way to go.
