AngularJS + Webpack如何哈希模板HTML

在使用gulp之前,我已经迁移了AngularJS应用程序以使用webpack。在gulp版本中,我曾使用rev插件来修订所有文件(css,js和html),但是在webpack模式下,我找不到将哈希添加到html模板的方法-当浏览器提供旧的html文件时,这会导致问题。如何解决?下面是通过webpack conf文件

const webpack = require('webpack');
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const OpenBrowserPlugin = require('open-browser-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

const RemoteServer = process.env.REMOTE_SERVER;
const appEnv = process.env.NODE_ENV || 'development';
const isProduction = appEnv === 'production';

const patterns = require('../server/src/main/resources/regex.json');

const appPath = path.join(__dirname, 'app');
const buildPath = path.join(__dirname, 'artifacts');

const config = {
    entry: [path.join(appPath, 'index.js')],

    output: {
        path: buildPath,

使用Webpack的主要好处之一是减少了浏览器为呈现应用程序而必须执行的请求数量,并使应用程序启动更快。 为了实现这一目标,它将“资源块”中的相关资源分组在一起,这些资源在一个请求中一起加载。单独加载所需的单个文件(如HTML模板)(没有特定原因)在此处可以视为反模式。

最佳实践是将所有相关的JS,HTML和CSS代码分组到一个大包中,然后一次加载,有时(对于较大的应用程序)从node_modules获得第二个“供应商”包,以加快开发速度,因为这块不会经常更改。

替代解决方案:

因此,在您的情况下,如果没有特定的理由将内容分开(您没有写过),我宁愿建议将HTML代码与控制代码一起放在一个块中,而不是分别加载HTML文件。

一个好的简单的起点是只构建两个块。用以下代码替换整个优化块:

GetCacheKey

这将构建两个块:一个主要块用于您的所有JS和HTML文件,另一个主要显式地用于node_modules文件夹中的所有内容。

这样,您就不必担心HTML文件的浏览器缓存,因为它们是在您的主要块中构建的,而且,这样做的好处是,您的应用程序启动速度更快。

我做了两年的类似迁移,所以我不需要那种解决方案。我的目标是将每个组件封装为一个模块,然后尽可能多地延迟加载。

// webpack config
{
  test: /\.html$/,
  use: ['html-loader'],
},

然后在每个组件中,我只需要样式和模板,如:

require('./_proposal-page.scss');

(function() {
  'use strict';
  angular.module('component.myComponent', []).component('myComponent', {
    template: require('./proposal-page.html'),
    controller: MyController,
  });

  /** @ngInject */
  function MyController($log) {
    const $ctrl = this;
    $ctrl.$onInit = function() {
      $log.log('$onInit myComponent');
    }
  }
})();
if (typeof module !== 'undefined' && typeof exports !== 'undefined' && module.exports === exports) {
  module.exports = 'component.myComponent';
}

Webpack检测到需求并将每个.html文件导出为一个模块,它运行平稳。
