Electron

Electron: A very handy framework that helps develop desktop apps with the aid of HTML, CSS and JavaScript

Electron offers the developers the possibility to build cross-platform apps using HTML, CSS, and JavaScript codes, while being an open-source GUI framework, and is well known for projects created with Electron (e.g. Arom, Nylas N1, GitKraken, GitHub, etc.)

It comes with three components: package.json (metadata, contains the app name and version), main.js (the main process, which creates windows and handles system-related events), and index.html (GUI, the webpage to display).

All the documentation and development details of Electron are complete and can be found on GitHub, which includes a quick start guide and application distribution details.

All in all, Electron is a very handy open-source GUI framework that comes with a clean interface for developing desktop apps with the aid of HTML, CSS and JavaScript.
