Syntax error in IE11 with Webpack, Babel and React

由 ↘锁芯ラ 提交于 2019-12-20 10:27:49
问题 I'm getting a Syntax Error in my React + Redux project in Internet Explorer 11, but I have no idea why it's caused. I'm using Webpack and Babel to compile it. I tried using babel-polyfill and babel-es6-polyfill, but that didn't help. This is the error I'm getting: SCRIPT1002: Syntax error File: app.js, Line: 70, Column: 1 Line 70 Column 1 is where the eval starts of Webpack: /***/ }), /* 21 */, /* 22 */ /***/ (function(module, exports, __webpack_require__) { "use strict"; eval("\n\nObject

VUE2组件懒加载浅析

VUE2组件懒加载浅析 vue2组件懒加载浅析 一、 什么是懒加载 懒加载也叫延迟加载，即在需要的时候进行加载，随用随载。 二、为什么需要懒加载 在单页应用中，如果没有应用懒加载，运用webpack打包后的文件将会异常的大，造成进入首页时，需要加载的内容过多，延时过长，不利于用户体验，而运用懒加载则可以将页面进行划分，需要的时候加载页面，可以有效的分担首页所承担的加载压力，减少首页加载用时 三、如何与webpack配合实现组件懒加载 　　1、在webpack配置文件中的output路径配置chunkFilename属性 1 2 3 4 5 6 output: { path: resolve(__dirname, 'dist' ), filename: options.dev ? '[name].js' : '[name].js?[chunkhash]' , chunkFilename: 'chunk[id].js?[chunkhash]' , publicPath: options.dev ? '/assets/' : publicPath }, 　　chunkFilename路径将会作为组件懒加载的路径 　　2、配合webpack支持的异步加载方法 resolve => require([URL], resolve), 支持性好 () => system.import(URL)

webpack构建vue项目（配置篇）

由 社会主义新天地 提交于 2019-12-20 07:18:09
最近公司要求用vue重构项目，还涉及到模块化开发，于是乎，我专门花了几天的时间研究了一下webpack这个目前来看比较热门的模块加载兼打包工具，发现上手并不是很容易，现将总结的一些有关配置的心得分享出来，欢迎大神来拍砖。。。 一、新建一个项目目录，cd /d 定位进去，然后输入npm init，会提示你填写一些项目的信息，一直回车默认就好了，或者直接执行npm init -y 直接跳过，这样就在项目目录下生成了一个package.json文件。 二、接下来就是通过npm安装项目依赖项，命令行输入：npm install babel-loader babel-core babel-plugin-transform-runtime babel-preset-es2015 babel-preset-stage-0 babel-runtime vue-loader vue-html-loader vue-hot-reload-api css-loader style-loader webpack webpack-dev-server --save-dev ，继续输入npm install vue@^1.0.26 --save 。 这里注意的几个点如下： 1.需要安装的依赖项视具体的项目需求来定，我只是安了几个必需的，后期会再加； 2.输入之后如果一直报错或者光标一直在转动
