169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason

Extensions-Hello-World
9 |
The Simplest Extension in the (Hello) World.
10 |
Motivation
11 |
The Hello World sample is designed to get you started building a Twitch Extension quickly. It contains all the key parts of a functioning Extension and can be immediately run in the Developer Rig. For a fast guide to get started, visit the Developer Rig documentation.
12 |
What's in the Sample
13 |
The Hello World Extension provides a simple scenario that demonstrates the end-to-end flow of an Extension. On the frontend, a user clicks a button that can change the color of a circle. Instead of changing the CSS locally, it calls its Extension Backend Service (EBS) to update the color of the circle. That message is then sent via Twitch PubSub to update all clients listening to the PubSub topic.
14 |
The sample is broken into two main components:
15 |
16 |
The Frontend of the Extension, comprised of HTML files for the different extension views and corresponding Javascript files and CSS. The frontend has the following functionality:
17 |
18 |
A button and script that makes a POST call to the EBS to request a color change for the circle
19 |
A GET call when the Extension is initialized to change the circle to the current color stored on the EBS
20 |
A listener to Twitch PubSub, that receives color change updates and then updates the circle color
21 |
22 |
23 |
A lightweight EBS that performs the following functionality:
24 |
25 |
Spins up a simple HTTPS server with a POST handler for changing color
26 |
Validates an Extension JWT
27 |
Sends a new color message via Twitch PubSub for a specific channel
28 |
29 |
30 |
31 |
Using the Sample
32 |
The recommended path to using this sample is with the Developer Rig. Use the Developer Rig's extension-init command to clone this repository.
33 |
The Developer Rig is able to host the frontend Hello World files, but the EBS must be run and hosted separately.
34 |
Setting Up Your Backend Certificates
35 |
Twitch Extensions require SSL (TLS).
36 |
If you're using the Developer Rig and used it to create this extension, it will have already configured the certificates. Otherwise, you'll need to set up a certificate for local development. This will generate a new certificate (server.crt and server.key) for you and place it in the conf/ directory. This certificate is different from the one used for the Developer Rig.
37 |
On MacOS
38 |
Navigate to the root of the Hello World extension folder and run npm install and then npm run cert
39 |
On Windows
40 |
Run the following commands to generate the necessary certificates for your Hello World backend
If you're using the Developer Rig, it has buttons in its UI to perform the following actions.
49 |
To run the EBS, run node services/backend, with the following command line arguments: -c <client id>, -s <secret>, -o <owner id>.
50 |
This provides the EBS with your Extension client ID, Extension secret and the user ID of the Extension owner (likely you). These are necessary to validate calls to your EBS and make calls to Twitch services such as PubSub.
51 |
If you do not want to pass in command line arguments, you can also directly set the following environment variables: EXT_SECRET, EXT_CLIENT_ID, EXT_OWNER_ID in your code.
To get the owner ID, you will need to execute a simple CURL command against the Twitch /users endpoint. You'll need your extension client ID as part of the query (this will be made consistent with the Developer Rig shortly, by using owner name).
Note - If you haven't yet created an extension, you can start that process here.

2 | An Twitch Extension that shows who're the TOP 10 visitors in a specific Twitch Channel.

4 | ## Motivation
5 | It's started during a streaming at [Lucas Montano Twitch Channel](https://www.twitch.tv/lucas_montano). The "Chat" has challenged Lucas Montano to work with a Stack he never worked with. The challange thread is called #umaStackQueNaoDomino

7 | **Note -** If you haven't yet created an extension, you can start that process [here](https://dev.twitch.tv/extensions).
