Hiroki Tagato f88751e60a devel/electron28: add port: Build cross-platform desktop apps with JavaScript, HTML, and CSS
Build cross platform desktop apps with JavaScript, HTML, and CSS.

It's easier than you think.

If you can build a website, you can build a desktop app. Electron is a
framework for creating native applications with web technologies like
JavaScript, HTML, and CSS. It takes care of the hard parts so you can
focus on the core of your application.
