WeChat Vue is a WeChat public account development framework built on Vue.js, which can help developers develop WeChat public accounts more quickly and efficiently. However, sometimes we need to close this Vue framework. This article will introduce in detail how to close WeChat Vue.

1. What is WeChat Vue

WeChat Vue is a framework that helps developers better develop WeChat official accounts. It is built based on Vue.js, so it has a lot of Vue.js Features, such as componentization, data binding, etc. WeChat Vue also provides encapsulation of some commonly used WeChat functions, such as obtaining user information, obtaining geographical location, etc. Using WeChat Vue allows developers to develop WeChat official accounts more quickly and efficiently.

2. How to close WeChat Vue

Sometimes we need to close the WeChat Vue framework. For example, in some specific cases, we want to use the native WeChat API instead of the encapsulation provided by WeChat Vue. So, how to close WeChat Vue?

1. Close WeChat Vue in the component

If we just want to close WeChat Vue in a certain component, we can call Vue in the life cycle function of the component. The prototype.$off method removes the event listener to prevent WeChat Vue from capturing WeChat events.

For example, we have a component called MyComponent, remove the WeChat event listener in the component's life cycle function beforeDestroy, the code is as follows:

export default {
  beforeDestroy() {
    this.$off('WechatJSBridgeReady')
    this.$off('WechatShareComplete')
  }
}

2. Close WeChat Vue in the entire application

If we want to close the WeChat Vue framework in the entire application, we can change Vue.prototype.$ in the main.js entry file The wechat attribute is an empty object. In this way, we are equivalent to invalidating all WeChat Vue components in the entire application.

The code is as follows:

import Vue from 'vue'
import App from './App.vue'

Vue.prototype.$wechat = {}

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

3. Close WeChat Vue in the production environment

If we want to close the WeChat Vue framework in the production environment, we can use Webpack's DefinePlugin sets the Vue.prototype.$wechat property to an empty object during compilation. In this way, we can turn off WeChat Vue in the production environment.

Specifically, we can add the following code snippet to the webpack.config.js file:

const webpack = require('webpack')

module.exports = {
  //...省略其他配置
  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      },
      'Vue.prototype.$wechat': '{}'
    })
  ]
}

It should be noted that this method can only be used in a production environment.
