1、使用 高版本 的 Webpack 和 Node.js 2、 多进程/多实例构建 :HappyPack(不维护了)、thread-loader 3、压缩代码 webpack-paralle-uglify-plugin uglifyjs-webpack-plugin 开启 parallel 参数 (不支持ES6) terser-webpack-plugin 开启 parallel 参数 多进程并行压缩 通过 mini-css-extract-plugin 提取 Chunk 中的 CSS 代码到单独文件,通过 css-loader 的 minimize 选项开启 cssnano 压缩 CSS。 4、 图片压缩 使用基于 Node 库的 imagemin (很多定制选项、可以处理多种图片格式) 配置 image-webpack-loader 5、缩小打包作用域 exclude/include (确定 loader 规则范围) resolve.modules 指明第三方模块的绝对路径 (减少不必要的查找) resolve.mainFields 只采用 main 字段作为入口文件描述字段 (减少搜索步骤,需要考虑到所有运行时依赖的第三方模块的入口文件描述字段) resolve.extensions 尽可能减少后缀尝试的可能性 noParse 对完全不需要解析的库进行忽略

一两个星期之前,你如果在我跟前说起私服的事情,我大概会绕着你走,因为我对这个东西真的一窍不通。事实上也正如此,开发同学曾不止一次的跟我说公司的私服版本太旧了,许多新的依赖编译之后不会从远程仓库自动缓存下来,然后每次就需要手动的上传,不方便极了。我听了之后,一方面确实因为各种忙碌没有抽开时间,但另一方面,则是每当打开私服面对着满屏的英文时,我都觉得眼前私服毕竟还能用,就不折腾了。 直到偶然一个契机,在网上看到一篇介绍nexus3.x的文章,文章写得也比较清晰,我也有兴致细读下去,就这样,开启了我的nexus3私服之旅。 开始我以为这个只是针对maven私服而存在的工具,后来才发现它所支持的,竟然将运维日常所面临的各种私服都包括了,这就极大的引发了我的钻研兴致,从maven私服的研究开始,一发不可收拾的,就又写出了一个nexus3系列教程,涵盖了安装,配置,maven私服,maven私服从2.x到3.x的迁移,docker私服,npm私服,yum私服,纵观全网络,大概也找不到一个人如此这般的,倾尽所有的,知无不言的,言无不尽的将nexus3作为一个系列写成文章的了。而现在,如果再有人与我说起私服的事情,至少我不会跑了,或许更想停下来了,,,哈哈。这就是付出学习所给人带来的心境上的转化! 前言啰嗦几句,愿您在这个小系列中,学习愉快! 想要查看本系列其他文章: 请点此处跳转 。

安稳与你 提交于 2020-02-21 13:00:08
问题 Anyway to run UglifyJS2 without node.js? Say I would like to run it in a JVM process using JavaScript script engine.

How to install node modules globally?

假装没事ソ 提交于 2020-01-17 05:23:12
问题 I have zero experience with npm other than knowing it exists. I believe I have managed to install uglify, but I have no idea how to use it. I had until recently been using Yuicompressor which had a java cli. How can I do something similar with uglify on a Windows 7 environment? Unless there is a step I skipped, the command line tools details the arguements, but my attempts to try such fail. https://github.com/mishoo/UglifyJS C:\Data\Websites\local\htdocs\b>npm install uglify-js uglify-js@2.7

Play 2.3.6 Java - OutOfMemory errors w/ sbt-uglify

有些话、适合烂在心里 提交于 2020-01-15 10:20:17
问题 I'm having an issue when trying to use the sbt-uglify plugin. I've configured the project per: https://github.com/sbt/sbt-uglify in plugins.sbt: addSbtPlugin("com.typesafe.sbt" % "sbt-uglify" % "1.0.3") in build.sbt: pipelineStages := Seq(uglify, digest, gzip) I have a non-trivial number of JS files (60+). What I've been getting is an OutOfMemory exception which prevents me from being able to complete a dist command. Has anyone else encountered this problem? Any ideas/solutions are

What's the difference between uglify-js and uglify-es?

你。 提交于 2020-01-14 13:33:11
问题 The descriptions of uglify-js and uglify-es are the same except that uglify-es tacks "for ES6+" on the end. Based on that one would think uglify-es is the best option for ES6 code. On the other hand, uglify-es is older - version 3.3.9 published 5 months ago, versus uglify-js at version 3.4.2 published 2 days ago. Anyone want to clear up my confusion? 回答1: uglify-js only supports ES5 code as input. uglify-es also supports ES6, but is buggy and has been abandoned. terser is a maintained

问题 I'm trying to build my project that uses webpack.

Can I tell UglifyJS to only compress and mangle all files except some which I only want concatenated?

自古美人都是妖i 提交于 2020-01-03 11:30:18
问题 Is it possible to specify and array of files that I want compressed and mangled (default Uglify behavior), but also a list of files that should not be touched, just concatenated? Thanks. 回答1: You can solve this in different ways. I'm posting an extended example to illustrate what one can do: uglify: { doAll: { options: { banner: '// <%= pkg.name %> - v<%= pkg.version %> - ' + '<%= grunt.template.today("yyyy-mm-dd HH:mm:ss") %>\n\n', mangle: { except: [ // mangle is true for all else besides

Webpack not minifying my bundle js

旧巷老猫 提交于 2020-01-03 02:59:16
问题 I'm now bundling my first project with webpack, everything works as expected except webpack is not minifying my bundle.min.js code. I'm pretty sure I'm doing something wrong, but can't spot the mistake. Any help would be appreciated. Thanks in advance. Here I go w/ my webpack.config.js var webpack = require("webpack"); var ExtractTextPlugin = require("extract-text-webpack-plugin"); var OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin'); module.exports = { context: _
