Attempting to debug this issue shows that removing "async" word makes the error disappear but I'm trying to use async. I have all the babel async plugins installed, defined in package.json and included in the plugins of webpack.config.js and .babelrc. Please help. my api.js let config = require('config'), $ = require('jquery') module.exports = { loggedIn: false, api: async (endpoint, params={}, method="GET") => { console.log

前端的工程化和自动化 grunt gulp browserify webpack 当今主流 webpack vue react angular 当前市面 2 个版本 webpack 3.0 webpack 4.0 webpack 4 一、webpack 基础认识 官网地址 官网: https://webpack.js.org/ 中文: https://www.webpackjs.com/ 前身: browserify 缺点，只能转化js webpack作用? 干嘛的: 项目管理、打包、模块管理(依赖问题)、加载资源(js/css/html/png…/woff/data/vue…),转换器(loader) 前身：grunt/gulp/browserify->webpack->pratcle webpack的历史 webpack1支持CMD和AMD，同时拥有丰富的plugin和loader，webpack逐渐得到广泛应用。 webpack2 支持ES Module，分析ESModule之间的依赖关系，webpack1必须将ES，Module转换成CommonJS模块，2支持tree sharking webpack3 新的特性大都围绕ES Module提出，如Scope Hoisting和Magic Comment； 前端的模块化 AMD : require.js CMD : sea

一、简介 webpack:JavaScript应用的静态 模块打包 工具 grunt/gulp（其它打包工具） grunt/gulp的核心是配置一系列的task，定义task要处理的事务（es6、ts转换，图片压缩，scss转css） 让grunt/gulp执行这些task，让整个流程自动化 grunt/gulp也被称为前端自动化任务管理工具。 当工程模块依赖非常简单是可以通过grunt/gulp进行简单的合并、压缩。 gurnt/gulp重点在于前端流程的自动化，webpack强调的是模块化开发管理，文件压缩合并只是附加功能。 二、简单使用 安装webpack 首先安装好node环境， npm install webpack@3.6.0 -g 安装低版本方便学习webpack 1.CommonJS的打包方式 // mathUtils.js function add(num1, num2) { return num1 + num2; } function mul(num1, num2) { return num1 * num2; } module.exports = { add, mul, } //main.js const {add,mul} require('mathUtils.js') console.log(add(1, 2)) console.log(mul(1, 2))

项目构建分析和 webpack 优化实践 最近接手在做一个chrom浏览器插件的项目，开发过程中发现项目打包的时间很长，足足有30多秒，这是让人很难接受的，而且构建的显示了几条包体积过大的提示信息： [image:073CB50B-06EB-4779-84FE-D11087B12BD7-47140-0000087E666F3C39/1967FDC4-F9FA-44F3-922E-5406A46415FB.png] 可以看到，打包后有三个包超过了建议的体积，是什么导致了打包时间长和包的体积过大呢？下面通过一些具体方法来分析原因和解决这个问题。 什么原因导致构建包变得这么大？ 为了分析是什么导致构建包为什么会变得这么大，可以安装 webpack-bundle-analyzer 插件，通过它可以直观地查看构建包中所有项目的大小。 npm install —save-dev webpack-bundle-analyzer 对应的需要在webpack 中做如下配置： webpack.config.js const { BundleAnalyzerPlugin } = require(‘webpack-bundle-analyzer’) plugins: [ ..., new BundleAnalyzerPlugin({ analyzerPort: 8081, }), ]
