Is uniapp a Web App or a native App?

As the mobile application market continues to develop, more and more companies and developers are looking for new technologies and solutions to help them create mobile applications in a short time. Among these solutions, React Native and Flutter have become the stars of the spotlight, but there is another framework that some people ignore, which is uni-app. So, is uni-app a Web App or a native App?

uni-app is a multi-terminal development tool. It is based on the Vue.js framework. By writing a set of codes, you can quickly develop products that support multiple platforms at the same time (mini programs, H5 pages, Apps, WeChat mini games). etc.) applications. This means that with only one code base, you can create different mobile applications at the same time, greatly simplifying the development process.

The core of uni-app consists of two parts: the code you write and the platform you run on. Among them, the code written is based on the single file component (.vue) of Vue.js. Developers can write uni-app applications just like developing Vue.js applications. In terms of running platforms, uni-app generates different code on different platforms. For WeChat mini programs and H5 pages, some JavaScript code runs in the browser environment; while for native applications and WeChat mini games, it runs outside the JavaScript engine.

uni-app is a "progressive framework" that provides a very powerful way to develop multi-platform applications. It uses many new technologies, such as Shadow DOM, Web Components, and Web Assembly, and combines these technologies to improve application performance and stability.

It should be noted that although uni-app can be developed across platforms, it is not a completely native application. uni-app only encapsulates native applications based on small programs on their respective platforms, so some restrictions and limitations cannot be avoided. Application developers need to have a clear understanding of these limitations so that design and planning can be put in place.

To sum up, uni-app is a tool that supports development across different platforms. It is mainly implemented through encapsulation steps rather than complete code conversion. Therefore, it can be said that it supports both Web App and native App development, and developers can develop applications for different platforms at the same time. However, uni-app cannot fully meet some of the strict requirements for native applications. Developers need to choose suitable solutions based on the various needs of applications on different platforms.
