The difference between uniapp and webview

With the rapid development of mobile Internet, our applications have transformed from simple web applications to multi-functional applications based on various platforms. Two particularly popular of these platforms are uniapp and webview. Although they may seem similar, there are actually some important differences between them. This article will explore the differences and features between uniapp and webview.

1. Application type:

uniapp is a cross-platform application framework that can build iOS, Android, H5 and various small programs at the same time. It can develop ordinary mobile applications just like ordinary web applications, but can be built using web technologies such as HTML, CSS and JavaScript.

Webview is an application type that is based on WebKit or Chromium kernel and has a small browser window built into the operating system. The application will be displayed in this window, and the pages within the application are built based on web technology.

2. Runtime environment:

uniapp provides a JavaScript-based framework and runtime environment that can execute JavaScript code on multiple platforms.

Webview is an application type provided by the operating system, and its running environment is the same as the operating system. On iOS, webview uses the WebKit engine, and on Android, it uses the Chromium engine.

3. Rendering:

In uniapp, the application is rendered with the assistance of system components, while in webview, the rendering is handled by the web engine provided by the system.

Uniapp's page layout is similar to HTML, with powerful style and layout control capabilities. Webview uses the same technologies as HTML, CSS, and JavaScript as web pages to render pages within the application.

4. Performance:

Because uniapp is also built based on web technology, the performance is not as good as native mobile applications. However, uniapp does a good job of autonomous optimization to improve the performance of the application as much as possible so that it performs well on the client.

In contrast, the rendering speed and performance of webview have been greatly optimized, and the overall performance is faster and smoother than uniapp.

5. Development process:

The development process of uniapp relies on front-end technology and frameworks. Developers do not need to study Android or iOS development documents in depth because uniapp provides a unified set of API for developers to use. Developers can take full advantage of existing HTML, CSS and JavaScript technologies to create mobile applications.

For webview, developers need to conduct in-depth study of Android or iOS development documents to write platform-specific code. This means that development times may be longer because more platform-specific knowledge needs to be acquired.

6. Summary:

Although the main function of uniapp and webview is to allow applications to be built using web technologies, they are very different. Although uniapp leverages existing technologies to develop cross-platform applications in a more unified way, it has never been able to reach the performance level of native applications. However, webview is much faster than uniapp because its rendering speed and performance optimization are much better, but most webview applications need to rely on platform-specific technology and documentation, which makes development costs higher and requires professional technical knowledge.

Therefore, developers should understand the pros and cons of both approaches when formulating an application development plan. Depending on the needs of the application and the required performance level, developers can choose the most suitable approach to build high-quality applications.
