The vue2.0 project cannot be opened by ie

With the development of front-end technology, more and more websites use Vue.js as the front-end development framework. However, when using Vue.js to develop projects, you may encounter the problem that IE browser cannot be opened. This article will introduce how to solve the problem that the Vue2.0 project cannot be opened in IE browser.

1. Problem background

When using Vue2.0 to develop projects, if there is a problem that the page cannot be opened in the IE browser, most of the reasons are because Vue2.0 does not support IE8 and below versions of browsers.

2. Solution

1. Import IE polyfill

Vue.js 2.0 uses ES6 syntax specifications for development, but ES6 syntax specifications are not Supported by IE8 and below. Therefore, we need to convert ES6 code to ES5, that is, use babel to escape. In addition, we also need to use IE polyfill to solve some features that ES5 cannot simulate.

First, we need to install babel and babel-polyfill. Run the following command in the terminal:

npm install babel-core@6.x babel-preset-env babel-polyfill --save-dev

Then, we introduce the above dependencies into the entry file of the project and convert the code to ES5 syntax. The specific code is as follows:

import "babel-polyfill";
import Vue from 'vue';

new Vue({
   el: '#app',
   render: h => h(App)
})

2. Install the IE compatible plug-in of Vue2.x

In addition to importing IE polyfill, we can also install the IE compatible plug-in of vue2.x. Implement support for ES6 in IE browser.

Run the following command in the terminal:

npm install es6-promise --save
npm install es6-object-assign --save

Then introduce the following code into the entry file of the project:

import 'es6-promise/auto'
import 'es6-object-assign/auto'

3. Summary

Through the above two In this way, we can solve the problem that the Vue2.0 project cannot be opened in the IE browser. Using IE polyfill can run on browsers that support ES5 syntax, and installing Vue2.x's IE-compatible plug-in can support ES6 specifications in IE browsers. No matter which method is used, corresponding configuration needs to be made in the project's entry file. At the same time, it is recommended that browser compatibility issues be fully considered during the development process to ensure the usability and stability of the project.
