GitHub Copilot Extension Backend Template

This is a template for creating a backend for the GitHub Copilot Extension. It is a simple Node.js server that listens for requests from the extension and responds with the appropriate data.

Stack

The template uses node.js as a base and express.js as the web server. It comes also with octokit.js to interact with the GitHub API. The template also includes the @copilot-extensions/preview-sdk package that helps simplifying the process of building an extension as agent.

• node.js
• express.js
• octokit.js
• @copilot-extensions/preview-sdk

Getting Started

After cloning the repository, you need to install the dependencies by running:

npm install

Then, you can start the server by running:

npm start

Start creating your extension by adding code to src/index.js on line 13:

app.post('/agent', (req, res) => {
    // Your agent code starts here
});

From there on it is up to you to implement the logic for your extension.

Devcontainer

This template comes with a devcontainer.json file that allows you to use Visual Studio Code's Remote - Containers extension to develop the extension in a containerized environment.

The container definition contains some settings for your convenience:

• GitHub Copilot is installed
• The port 3000 is exposed when the container is started. This way you can used the codespace as server to run your backend. Read more on how to do it in this article.
