Mithril - A Javascript Framework for Building Brilliant Applications

Mithril is a modern client-side Javascript framework for building Single Page Applications. It's small (8.18 KB gzipped), fast and provides routing and XHR utilities out of the box. It supports virtual dom, which is a Javascript data structure that describes a DOM tree. It consists of nested virtual DOM nodes, also known as vnodes.

It is comparable to Facebook react. Its overall size is 8 GB (gzipped) and its performance is better than its competitors. Mithril is used by many well-known companies (e.g. Vimeo, Nike, Fitbit), and it powers large open-sourced platforms too (e.g. Lichess, Flarum).
