Installation

Use npm to install this plugin, and you also need to install html-webpack-plugin.

npm install --save-dev page-skeleton-webpack-plugin

npm install --save-dev html-webpack-plugin

Basic Use

Step 1：configration

After installing the plug-in according to the above tutorial, you need to configure the plugin so that the plugin can run normally. The plugin will perform different operations depending on the environment of the node. When NODE_ENV === 'development', the plug-in can perform operations for generating and writing skeleton pages.

const HtmlWebpackPlugin = require('html-webpack-plugin')
const { SkeletonPlugin } = require('page-skeleton-webpack-plugin')
const path = require('path')
const webpackConfig = {
  entry: 'index.js',
  output: {
    path: __dirname + '/dist',
    filename: 'index.bundle.js'
  },
  plugin: [
    new HtmlWebpackPlugin({
       // Your HtmlWebpackPlugin config
    }),
    new SkeletonPlugin({
        pathname: path.resolve(__dirname, `${customPath}`), // the path to store shell file
        staticDir: path.resolve(__dirname, './dist'), // the same as the `output.path`
        routes: ['/', '/search'], // Which routes you want to generate skeleton screen
    })
  ]
}

Since the plugin selects different operations based on the process.env.NODE_ENV environment variable, so you need to configurate environment variables in the scripts option in the package.json file as follows:

"scripts": {
  "dev": "cross-env NODE_ENV=development node server.js",
  "build": "rm -rf dist && cross-env NODE_ENV=production webpack --progress --hide-modules"
}

That is, setting NODE_ENV to development in the development environment and NODE_ENV to production in the production environment.

Step 2：Modify template `index.html` of html-webpack-plugin

Add comment  in the root element of you application.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Document</title>
</head>
<body>
  <div id="app">
    <!-- shell -->
  </div>
</body>
</html>

Step 3：Operations and write shell

In the development page, use CtrlOrCmd + enter to call out the plugin interactive interface, or enter the toggleBar callout interface in the browser's JavaScript console.

Click the button in the interactive interface to preview the skeleton page. This process may take about 20s. After the plugin is ready for the skeleton page, it will automatically open the preview page through the browser, as shown below.

Scan the QR code in the preview page to preview the skeleton page on the mobile phone. You can directly edit the source code on the preview page. Write the skeleton page into the shell.html file by clicking the Write button in the upper right corner.

Re-package the application with webpack. When the page is restarted, you can see the application's skeleton structure before getting the data.
