Created using Jan extension example

Create a Jan Extension using Typescript

Use this template to bootstrap the creation of a TypeScript Jan extension. 🚀

Create Your Own Extension

To create your own extension, you can use this repository as a template! Just follow the below instructions:

1. Click the Use this template button at the top of the repository
2. Select Create a new repository
3. Select an owner and name for your new repository
4. Click Create repository
5. Clone your new repository

Initial Setup

After you've cloned the repository to your local machine or codespace, you'll need to perform some initial setup steps before you can develop your extension.

Note

You'll need to have a reasonably modern version of Node.js handy. If you are using a version manager like nodenv or nvm, you can run nodenv install in the root of your repository to install the version specified in package.json. Otherwise, 20.x or later should work!

1. 🛠️ Install the dependencies

   npm install

2. 🏗️ Package the TypeScript for distribution

   npm run bundle

3. ✅ Check your artifact

   There will be a tgz file in your extension directory now

Update the Extension Metadata

The package.json file defines metadata about your extension, such as extension name, main entry, description and version.

When you copy this repository, update package.json with the name, description for your extension.

Update the Extension Code

The src/ directory is the heart of your extension! This contains the source code that will be run when your extension functions are invoked. You can replace the contents of this directory with your own code.

There are a few things to keep in mind when writing your extension code:

• Most Jan Extension functions are processed asynchronously. In index.ts, you will see that the extension function will return a Promise<any>.

  import { events, MessageEvent, MessageRequest } from '@janhq/core'
  
  function onStart(): Promise<any> {
    return events.on(MessageEvent.OnMessageSent, (data: MessageRequest) =>
      this.inference(data)
    )
  }
