This library provides an Elixir library for twitch API. It makes use of an Elixir scrapper for [Twitch API](https://github.com/kamiyuzu/twitch_api_scraper).

## Library configuration

For making use of this library you will need to create a `.env` with the env vars from the `.env_example`. The env vars needed have to be fetched from [twitch developer documentation](https://dev.twitch.tv/docs/api).

In the [.env](.env) file environment vars needs to be defined for usage. Those need to be loaded when working with this project. To do so, one can manually execute:

```bash
source .env
```

or automate this process using [direnv](https://direnv.net/).

```bash
# Install direnv using brew
$ brew install direnv

# From the project folder
$ direnv allow
```

Continue with the instructions [here](https://github.com/direnv/direnv#setup)

## Library usage

The library provides dynamically modules for fetching all Twitch API endpoints. The convention is: `TwitchApi.<TwitchCategory>.<Action><Endpoint>`. The convention might not be a rule since Twitch reference do not follow this rule always.

This is an example running iex:

```elixir
iex(1)> h TwitchApi.Users.GetUsers

                            TwitchApi.Users.GetUsers                            

⛔ This module is autogenerated please do not modify manually.

## Example request from twitch api docs:

### descriptions:

This gets information about user 141981764.

### requests:

curl -X GET 'https://api.twitch.tv/helix/users?id=141981764' -H'Authorization:
Bearer cfabdegwdoklmawdzdo98xt2fo512y' -H'Client-Id:
uo6dggojyb8d6soh92zknwmi5ej1q2'
