Create custom elements, bind data, route switching, and quickly develop WebApps based on custom elements. Stripped from [mt-music-player](https://github.com/mantou132/mt-music-player).

## Features

- **Lightweight:**

  The whole librarie is divided into three modules (custom elements, global data management, routing), you can choose whether to use the built-in custom elements, all the content is packaged together and only 15kb(br compression).

- **Simple:**

  There is no new syntax, everything is HTML, CSS, JavaScript. There is no superfluous concept, only "Observe" is needed to create reactive custom elements;

- **High performance:**

  The template engine uses [lit-html](https://github.com/Polymer/lit-html), bundle size, performance of addition, deletion, modification, and memory usage are better than React and Vue, [here](https://rawgit.com/krausest/js-framework-benchmark/master/webdriver-ts-results/table.html) is the performance comparison between lit-html and React and Vue;

- **Asynchronous rendering:**

  which will avoid blocking the main thread for a long time when continuously rendering (such as creating a list) of element, providing a smooth user experience;
