## Development

To develop `go-twitch-ext` or interact with its source code in any meaningful way, be
sure you have the following installed:

### Prerequisites

- [Git][git]
- [Go 1.12][golang]+

You will need to activate [Modules][modules] for your version of Go, generally
by invoking `go` with the support `GO111MODULE=on` environment variable set.

### Twitch Extension Configuration
From your [Twitch Extension Dashboard](https://dev.twitch.tv/dashboard/extensions) you can get the following:
- Client ID
- Base64 Secret
- Extension Version
- Extension (**Broadcaster**/**Developer**) Config Version - *OPTIONAL*

### Owner ID
To get the owner ID, you will need to first create a temporary access token via [https://twitchtokengenerator.com/](https://twitchtokengenerator.com/)

Next fetch your ownerID from a simple CURL command against the Twitch `/users` endpoint.
You'll also need the client ID from [https://twitchtokengenerator.com/](https://twitchtokengenerator.com/) as part of the query.

```bash
curl -H "Client-ID: " -H "Authorization: Bearer " -X GET "https://api.twitch.tv/helix/users?login="
```

your ownerID is the value of 'id'

```bash
{
"data": [{
"id": "35851594",
"login": "crazyjack12",
"display_name": "crazyjack12",
"type": "",
"broadcaster_type": "",
"description": "Do What Thou Wilt",
"profile_image_url": "https://static-cdn.jtvnw.net/jtv_user_pictures/ea0bf955-255a-4eca-ad80-460b88162910-profile_image-300x300.png",

}
```
