uni-app is a framework for developing all front-end applications using Vue.js, developers write a set of codes, which can be published to iOS, Android, Web ( Responsive), as well as various small programs (WeChat/Alipay/Baidu/Toutiao/Feishu/QQ/Kuishou/DingTalk/Taobao), Quick Apps and other platforms.
The DCloud company has 9 million developers, millions of applications, 1.2 billion mobile monthly active users, thousands of uni-app plug-ins, and 70+ WeChat/QQ groups. The official Alipay tool has built-in uni-app (see), and Tencent Classroom officially recorded training courses for uni-app (see), developers can choose with confidence.
With uni-app in hand, you don't have to worry about doing anything. Even if it is not cross-end, uni-app is a better applet development framework (see details), a better App Cross-platform framework, more convenient H5 development framework. No matter what kind of project the leader arranges, you can deliver it quickly, without changing the development thinking or changing the development habits.
# Quick experience
It is not a dream to compile a set of code to 14 platforms. Seeing is believing, scan 14 QR codes and experience the most comprehensive cross-platform effect for yourself!
Note:
- Some platforms cannot submit simple demos, so some other functions have been added; the hello uni-app sample code can be obtained from [github](https://github.com/dcloudio/hello-uniapp)
-Quick QuickApp only supports vivo, oppo, Huawei
- The 360 MiniApp is only supported by the windows platform and needs to be opened in the 360 browser
# Watch the video and learn about uni-app in 10 minutes
We carefully prepared a simple ten-minute introduction video, so that you can quickly understand the main features of uni-app:
# Why choose uni-app?
uni-app在开发者数量、案例、跨端抹平度、扩展灵活性、性能体验、周边生态、学习成本、开发成本等8大关键指标上拥有更强的优势。
开发者/案例数量更多
数百万应用、uni统计月活12亿、70+微信/qq群、更高的百度指数
跨端完善度更高，真正落地的提高生产力
平台能力不受限
在跨端的同时，通过条件编译+平台特有API调用，可以优雅的为某平台写个性化代码，调用专有能力而不影响其他平台。
支持原生代码混写和原生sdk集成。
学习成本低
基于通用的前端技术栈，采用vue语法+微信小程序api，无额外学习成本。
开发成本低
不止开发成本，招聘、管理、测试各方面成本都大幅下降。
HBuilderX是高效开发神器，熟练掌握后研发效率至少翻倍（即便只开发一个平台）。
# Functional frame diagram
As can be seen from the functional frame diagram of uni-app below, uni-app does not sacrifice the platform features in the process of cross-platform, but can gracefully call the platform's proprietary capabilities, and truly embrace all rivers and learn from each other's strengths.
# One set of code, running on multiple platforms
uni-app implements a set of codes that run on multiple platforms at the same time; as shown in the figure below, a set of codes runs on iOS emulators, Android emulators, web, WeChat developer tools, Alipay MiniApp Studio, Baidu Developer Tools, ByteDance Developer Tools, QQ Developer Tools (each terminal tab at the bottom represents 1 terminal emulator):
The actual running effect is as follows (click on the picture to enlarge):
