How is vue compatibility? How to solve?

Vue.js is a popular JavaScript library that makes it easier for developers to build interactive web applications. Although Vue.js has a wide user base and support, Vue compatibility has always been a concern for many developers. In this article, we will discuss Vue compatibility, including its browser compatibility, mobile device compatibility, IE compatibility and other related issues.

Vue’s browser compatibility

The basic code of Vue.js is just some native JavaScript syntax, so it can run normally in all browsers that support JavaScript. This means Vue.js performs well in modern browsers such as Chrome, Firefox, Safari, and Edge.

However, Vue.js may not be fully compatible on some older versions of browsers. Especially on browsers of IE11 and below, some problems may occur with Vue.js. These problems include:

• Compiler error.
• CSS binding does not work.
• Vue components will not render.

In browsers of IE11 and below, the main reason for compatibility issues is the lack of support for ES6, so Vue.js cannot run correctly. Although the official Vue.js documentation does not mandate the use of IE11, if you need to be compatible with these older versions of browsers, you need to take some special measures, such as using babel to translate the Vue.js code, or using polyfill to provide some Objects and methods missing from the browser.

Vue’s Mobile Device Compatibility

Similar to browser compatibility, Vue.js also performs well on mobile devices, especially on iOS and Android devices. Many mobile applications use Vue.js to build their front ends. These applications include: NetEase Cloud Music, Xiaomi Mall, etc.

Despite this, Vue.js may also have some compatibility issues on mobile devices. Especially on older versions of mobile devices, Vue.js may have performance issues, causing the application to run slower. Therefore, when using Vue.js to develop mobile applications, try to use newer mobile devices or use newer mobile device browsers.

Vue’s IE compatibility

As mentioned before, Vue.js is not fully compatible with IE browsers of IE11 and below. Especially on browsers of IE9 and below, Vue.js can hardly run properly.

Although IE browsers are not as popular as they used to be, many users still use them, especially within some enterprises. Therefore, if your application needs to be compatible with older versions of IE, then you need to pay special attention to Vue.js compatibility.

How to solve Vue compatibility issues

In order to solve Vue compatibility issues, we can use the following methods:

1. Manually check browser compatibility

Before developing a Vue.js application, we can first check the compatibility of the target browser. This way problems can be discovered as early as possible and targeted measures can be taken.

2. Using polyfill

Polyfill is a code library of Javascript properties or functions used to add missing or incorrect properties or functions to older browsers. We can use polyfills to provide support for ES6 syntax so that Vue.js can run properly on older versions of browsers.

3. Using babel

Babel is a tool for converting new ECMAScript 6 code into ES5 code. This enables modern JS libraries and frameworks such as Vue.js to be supported in older browsers and IE.

Conclusion

Vue.js is a powerful front-end framework that has good compatibility in modern browsers and mobile devices. However, Vue.js compatibility problems may occur in IE browsers IE11 and below, and on some older mobile devices. Therefore, as a developer, we need to take appropriate measures against these issues to ensure that our applications work properly on all target devices.
