使用Grunt.js走进前端构建 新时代 TooBug 2013.3
那一年,世界还很美好 写HTML 写HTML+CSS 写HTML+CSS+JS 发布
直到“性能”遇到了前端 写HTML 写CSS 写JS 压缩CSS 合并CSS 雪碧图 压缩JS 合并JS Base64
图片压缩 时间戳 …… 发 布
前端开始有了预处理工具 ◦ YUI Compressor (Java) ◦ Google Closure Compiler (Java)
◦ CSS Tidy/Clean CSS (online) ◦ uglify (JavaScript) ◦ CSS Gaga (Windows) ◦ ……
问题随之而来 ◦ 学习门槛 * 每个工具 * 每个人 ◦ 流程约定 &
规范 * 每个人 ◦ 初始化需要安装各种平台 ◦ 复杂的配置或者约定 ◦ 跨平台? ◦ 配置漫游?
除了性能,还要质量 ◦ HTML validate ◦ CSS validate ◦ CSS Lint
◦ JSLint/Hint ◦ 测试(单元测试 、黑盒测试) ◦ ……
除了它俩,还有可维护性以及“爽” ◦ LESS & BootStrap 动态样式语言,“最像CSS” ◦ SASS & Compass
动态样式语言,“最强大” ◦ Stylus 动态样式语言,“最优雅” ◦ Coffee & Coco 类python语法,填补了一些坑 ◦ Type Script 来自Microsoft ◦ Dart 来自Google
自己动手,丰衣足食 手工 ◦ …… ◦ …… ◦ …… ◦ ……
◦ 杀了我吧!!! 批处理 ◦ 学习成本高昂 ◦ 编写成本尤其高昂 ◦ 维护? ◦ 跨平台?
瑞士军刀——Grunt.js Grunt.js 压缩/合并 CSS 压缩/合并 JS 雪碧图 BASE64 图片优化 时间戳
LESS/SASS/Stylus/ Coffee/Coco 单元测试 黑盒测试 Lint/Hint Validate 想象力
何方神圣? ◦ 开源项目(gruntjs.com) ◦ 基于Node.js ◦ 命令行 ◦ 跨平台(Win/OS X/Linux)
◦ 使用时以任务(Task)为构建颗粒 ◦ 任务描述使用配置文件 ◦ 插件式(仅自带极少构建功能)
一堵芳容 $ grunt Running "jshint:gruntfile" (jshint) task >> 1 file
lint free. Running "jshint:src" (jshint) task >> 1 file lint free. Running "jshint:test" (jshint) task >> 1 file lint free. Running "qunit:files" (qunit) task Testing test/tiny-pubsub.html....OK >> 4 assertions passed (23ms) Running "clean:files" (clean) task Cleaning "dist"...OK Running "concat:dist" (concat) task File "dist/ba-tiny-pubsub.js" created. Running "uglify:dist" (uglify) task File "dist/ba-tiny-pubsub.min.js" created. Uncompressed size: 389 bytes. Compressed size: 119 bytes gzipped (185 bytes minified). Done, without errors.
得到ing开始(getting started) 1. 本机环境 a. 安装Node.js(http://nodejs.org) b. 设置代理(npm set proxy=http://....com:8080)
c. 安装Grunt-CLI(npm install -g grunt-cli) 2. 项目配置 a. 准备package.json(npm init) b. 安装依赖(npm install grunt-contrib-xx --save-dev) c. 准备Gruntfile.js(即构建任务) 3. 构建 a. grunt b. 木有了……
常用插件 ◦ grunt-contrib-jshint ◦ grunt-contrib-csslint* ◦ grunt-contrib-uglify ◦ grunt-contrib-cssmin ◦
grunt-contrib-concat ◦ grunt-contrib-copy ◦ grunt-usemin** ◦ grunt-htmlhint***
