-Weex dedicates to enable developers to use modern web development
experience to build both Android, iOS and web apps with a single codebase. In
practice, you can use javascript and modern front-end frameworks to develop
mobile apps after integrating the WeexSDK.

-The structure of Weex is decoupled, the render engines are separated from
the syntax layer. Weex doesn't rely on any specific front-end framework, it
mainly supports [Vue.js](https://vuejs.org/) and
[Rax](https://alibaba.github.io/rax/).

-Another primary goal of Weex is to keep up with modern development
technologies and platform capabilities both for web and native. Productivity
and performance can coexist in Weex. Writing Weex pages feels the same like
writing web pages. Rendering Weex pages is just the same as rendering native
pages.

## Overview
-If you just want to try Weex, You don't need to install anything. There is
an [online playground](http://dotwe.org/vue/) of Weex, you can write single
page examples on it without any configurations. The source code should be
written in Vue.js [single file
component](https://vuejs.org/v2/guide/single-file-components.html) syntax (also
known as the `*.vue` files), and the render result of the web platform will be
displayed in a mocked phone shell.

Here is an
[example](http://dotwe.org/vue/8da01827631b21150a12dd54d7114380) written in
Weex and Vue.js:

-This example renders a word "Yo" in the center of the screen. If you want
to preview the rendered result on mobile devices, you need to install the [Weex
playground app](/tools/playground.html) or integrate Weex SDK into your own
app. Then scan your page's QR code with your playground app or your own app
(with the QR scan feature to load scanned URL with Weex SDK), and you will see
the rendered result on your device.
