Plug-ins to be used in the project optimization process


erp PC front-end project

Dependent installation

npm install element-ui --save

With the help of babel-plugin-component, we can only introduce the required components in order to reduce the size of the project.

npm install babel-plugin-component -dev

  1. Component description and description
<!-- erp Components and descriptions in the project are placed in portal Under the project In file -->
  1. Component demo address:
  erp All encapsulated components in the project demo All put in frame Under the project demo Folder
  demoComponent.vue File Representation Component demo Instances to see if there are components you need
  demoForm.vue Express form Form component
  invoiceAdd.vue form Form Components, Generated by Code Generator
  invoiceList.vue table List Components, Generated by Code Generator
frame -> demo -> demoComponent.vue
              -> demoForm.vue
              -> invoiceAdd.vue
              -> invoiceList.vue 
  1. Global Common Style View
  The global public demonstration in erp system is placed in SRC - > CSS file - > public - > commonBase. SCSS under portal project 
  commonBase.scss Global Common Style, no need to introduce, take it over and use it directly
  commonBase.css is a static resource file used in commonBase.html

  How about the specific style, you can open commonBase.html directly in the browser

   * Type: Object
   * All webpack-dev-server options are supported
   * Some values, such as host, port, and https, may be overwritten by command-line parameters
   * Some, such as publicPath and historyApiFallback, should not be modified because they need to synchronize with the development server's baseUrl to ensure normal operation.
  devServer: {
    port: 18080, //Project port
    proxy: PROXY, //This tells the server to proxy any unknown requests (requests that do not match static files) to the url configured in PROXY
    disableHostCheck: true, //Turn off host detection (configure this to be accessible via domain name)
    compress: true, // Code compression

   *  Configure other options for Webpack
   *  warning
      Some webpack options are based on values in vue. config. js, so they cannot be modified directly. For example, you should modify the output Dir option in vue. config. JS rather than the output.path; you should modify the baseUrl option in vue. config. JS rather than the output.publicPath option. This is because the values in vue.config.js are used in multiple places in the configuration to ensure that all parts work together.
