This is an example of the simplest way of creating an addon. It has front end code and it does not use any back end code. The example contains a html file, manifest.json and the icon. We have used python to serve files and ngrok to forward our inner port to a public domain.

Pull the code from git and open the HTML file or serve it with any web server.

1. Install python on your local machine
2. Go to the root folder of the project
3. Use one liners python-http

1. Create free account at ngrok
2. Follow their guideline for installing & running app docs
3. After generating the url get the new url domain and add it to our manifest.json file

This app uses data from open-meteo, a free open-source Weather API.
You can read their API open-meteo
