Vue browser is not compatible

With the development of mobile Internet, people are increasingly using mobile phones and tablets to browse the web in their daily lives. At the same time, various browsers are emerging in endlessly, such as Chrome, Safari, Firefox, etc. In this diversified environment, the issues that web developers need to pay attention to have become more complicated, one of which is browser compatibility.

Vue is a very popular JavaScript framework. Its emergence has greatly improved the efficiency of front-end development. However, when developing Vue applications, we often encounter browser compatibility issues, especially in older browsers. This article will introduce some situations that may cause Vue incompatibility and provide some solutions.

1. ES6 is not compatible

Vue is written using ES6, which is an evolved version of JavaScript. Since ES6 was first released in 2015, older browsers may not support it. If you try to run a Vue application on a browser that does not support ES6, you may encounter errors.

Solution: Use Babel to convert code to ES5

Babel is a converter that converts ES6 code to ES5 code so it can run in older browsers. Using Babel in a Vue application is very simple, just install the relevant plugin according to the documentation.

2. CSS incompatible

The Vue framework uses a componentized architecture, so each Vue component should contain its own style sheet (CSS). However, CSS behaves differently in different browsers. For example, the CSS parsing behavior in IE is different from other browsers.

Solution: Refactor the style sheet

First of all, you should try to avoid using IE-specific CSS properties, or use alternatives that are compatible with mainstream browsers. Second, you can dynamically load different CSS files based on browser type. Finally, you can use a CSS preprocessor to generate CSS code that is compatible with different browsers.

3. Does not support WebSocket

Vue.js needs to use WebSocket to achieve real-time communication functionality. WebSocket is a communication protocol based on the TCP protocol used to transmit data between the browser and the server.

Solution: Use polyfill or downgrade WebSocket

If your application needs to run on older versions of browsers, you can use WebSocket's polyfill, which can simulate WebSocket behavior, In order to implement real-time communication function on browsers that do not support WebSocket. Another solution is to downgrade WebSocket. You can use technologies such as Long Polling or Server-Sent Events to implement real-time communication capabilities.

4. Inconsistent prefixes

Different browsers have inconsistent prefix requirements for different CSS attributes. For example, some browsers require CSS properties to be prefixed with webkit, while some browsers require the -moz- prefix.

Solution: Use autoprefixer to automatically add prefixes

autoprefixer is a CSS prefix automatic adder. It detects the browser type and automatically adds the correct prefix to CSS properties. In a Vue application, you can use autoprefixer as a Webpack plugin to automatically add prefixes.

5. Incompatible JSX syntax

JSX syntax is an innovation in the React framework that makes working with components easier. However, the Vue framework does not support JSX syntax by default, so JSX syntax may cause compatibility issues when using the Vue framework.

Solution: Use Vue’s official JSX plug-in

The Vue team has developed a plug-in called Vue JSX, which can implement JSX syntax in the Vue framework. Use this plugin to easily migrate Vue applications to JSX syntax while supporting all major browsers.

Summary

Vue is a very powerful JavaScript framework, but developers need to face many challenges in terms of browser compatibility. In this article, we discussed issues such as ES6 incompatibility, CSS incompatibility, non-WebSocket support, inconsistent prefixes, and incompatible JSX syntax and provided some solutions. As long as you understand these solutions, you can run Vue applications beautifully on various browsers.
