Yesterday evening I decided to create a Chrome Extension for my screen recorder website ( https://www.screenrecorder.online/ ).
All I needed to create was a manifest.json and background.js file to embed my HTML page as Popup after a click on the toolbar button.
The manifest.json if quite simple:
"name": "Online Screen Recorder",
"description": "This extension provides you with a free, fast, and straightforward way to record your screen.",
The background.js contains only the click event listener and opens the same HTML I use on the website (I stored it as popup.html).
The remaining thing to do after that was to create a ZIP file of the extensions folder and upload it to the chrome web and MS Edge Addon store.
The code of the website itself is available on GitHub:
