Imagine if we could generate a web application compatible with all the browsers, apps for all the notable mobile platforms and desktop applications for the major operating systems – all of this from a single code base. The powerful new JavaScript framework, Electron, is a bold step in this direction. This revolutionary tool enables development of cross-platform desktop applications using the already well-known web technologies - HTML, CSS and JavaScript, which can dramatically increase code reuse between your web and desktop applications. The talk is a presentation of the features, underlying concepts and possibilities of this GitHub-sponsored open-source framework.
