uni app is not an app, but a set of open source frameworks that can be applied to multiple terminals. It is a framework that uses Vue.js to develop all front-end applications; uni-app implements a set of codes and publishes them to iOS and Android at the same time , WeChat applet and other 11 platforms.
The operating environment of this tutorial: windows7 system, uni-app version 2.5.1, DELL G3 computer.
uni-app is a set of open source frameworks that can be applied to multiple terminals. It is a framework that uses Vue.js to develop all front-end applications. Developers write a set of codes that can be published to iOS, Android, and Web (responsive ), as well as various small programs (WeChat/Alipay/Baidu/Toutiao/QQ/DingTalk/Taobao), quick applications and other platforms.
uni-app is more friendly to front-end developers and has lower learning costs because uni-app is based on vue.js. And its encapsulated components are the same as those of WeChat applet, so the learning cost for current mainstream front-end personnel is almost 0.
uni-app uses HbuildX for development. Development using HBuilderX can be said to be extremely fast. The development speed is relatively fast, ps: I am a webstom party (very familiar with Vue), but for developing pure static pages, I use HBuilderX. I personally think it is very good, both in terms of environment and prompt effects.

uni-app inherits from Vue.js and provides a complete Vue.js development experience.
uni-app component specification and extension API are basically the same as WeChat applet.
Developers with some experience in Vue.js and WeChat applet development can quickly get started with uni-app and develop applications that are compatible with multiple terminals.
uni-app provides conditional compilation optimization, which can elegantly write personalized code for a certain platform and call proprietary capabilities without affecting other platforms.
uni-app still uses the 5 engine when packaged into App, and all capabilities of 5 can be used in uni-app. The running performance on the App side is basically the same as that of the WeChat applet.
For technicians: There is no need to learn so many platform development technologies and research so many front-end frameworks. It is enough to learn uni-app based on vue.
For companies: lower cost, covering more users, uni-app is an efficient tool.
uni-app multi-terminal demonstration
In order to facilitate developers to experience the components, interfaces and templates of uni-app, DCloud has released the Hello uni-app demonstration program (the code has been open source, see Github for details), uni- The app implements a set of codes and publishes it to 11 platforms including iOS, Android, and WeChat applets at the same time. Seeing is believing, scan the 11 QR codes and experience the most comprehensive cross-platform effect for yourself!
#Why choose uni-app?
uni-app has stronger performance in 8 key indicators such as number of developers, cases, cross-end smoothness, expansion flexibility, performance experience, surrounding ecology, learning cost, and development cost. Advantage.

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
