. 安装Node.js
http://nodejs.org/download/
2. 加速NPM安装
npm install -g cnpm --registry=http://r.cnpmjs.org
安装cnpm国内镜像, 以后所有npm命令换成用cnpm执行即可
3. 安装grunt
npm install -g grunt-cli
4. 在工程目录下建立配置文件Gruntfile.js
本例中, 所做的事情包括:
a. 组合一些less到一个文件
b. 用less编译不同版本的css
c. 填充html模版并部署
d. 实时侦听以上变化并自动做相应编译
<!-- code begin -->
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
concat: {
options: {
banner: '/*! APP.common.css@<%= pkg.name %> - v<%= pkg.version %> - ' +
'<%= grunt.template.today("yyyy-mm-dd") %> */'
},
mobileLess: {
src: ['src/mobile/less/APP_common/*.less'],
dest: 'src/mobile/less/APP.common_grunt.less',
}
},
less: {
development: {
options: {
compress: false,
yuicompress: false
},
files: {
"css/APP.common.css": "src/mobile/less/APP.common_grunt.less",
"css/APP.web.index.css": "src/web/less/APP.web.index.less"
}
},
production: {
options: {
modifyVars: {
imagepath_page: '"/misc/images/"',
imagepath: '"/misc/images/"'
},
compress: true,
yuicompress: true,
optimization: 2
},
files: {
"css/pub/APP.common.css": "src/mobile/less/APP.common_grunt.less",
"css/pub/APP.web.index.css": "src/web/less/APP.web.index.less"
}
}
},
htmlbuild: {
mobile: {
src: 'src/mobile/html/*.html',
desc: './',
options: {
beautify: true,
relative: true,
sections: {
layout: {
footbar: 'src/mobile/html/inc/footbar.html'
}
}
}
},
web: {
src: 'src/web/html/*.html',
desc: './'
}
},
watch: {
options: {
livereload: true
},
grunt: {
files: ['Gruntfile.js']
},
styles: {
files: [
'src/**/less/*.less',
'src/**/less/**/*.less'
],
tasks: [
'concat:mobileLess',
'less'
],
options: {
nospawn: true
}
},
htmls: {
files: [
'src/**/html/*.html',
'src/**/html/**/*.html'
],
tasks: [
'htmlbuild'
],
options: {
nospawn: true
}
}
}
});
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-contrib-less');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-html-build');
grunt.registerTask('default', ['watch']);
};
<!-- code end -->
5. 建立并配置 package.json
在项目目录下运行 npm init , 填写出现的各种选项, 或者直接回车到完成
打开生成的 package.json, 并添加 devDependencies 节点 --如果后续的编译出错, 往往是这里的版本号不够新
<!-- code begin -->
{
"name": "html",
"version": "0.0.0",
"description": "",
"main": "Gruntfile.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"devDependencies": {
"grunt": "~0.4.1",
"grunt-contrib-concat": "~0.4.0",
"grunt-contrib-less": "~0.11.0",
"grunt-contrib-watch": "~0.6.1",
"grunt-html-build": "~0.3.2"
}
}
<!-- code end -->
6. 安装项目依赖包
在项目目录下运行 cnpm install , 将把 package.json->devDependencies下注明的依赖包下载到 node_modules
7. 运行grunt
在项目目录下执行 grunt 即可
