以下是压缩js,css和css合并,html,img,js语法检查
要想实现这些，需要在命令行里下载：
js: npm install grunt-contrib-uglify --save-dev
css: npm install grunt-contrib-cssmin --save-dev
npm install grunt-contrib-concat --save-dev
html: npm install grunt-contrib-htmlmin --save-dev
js语法检查： npm install grunt-contrib-jshint --save-dev
module.exports = function(grunt) {
//任务配置，所有插件的配置信息
grunt.initConfig({
// 压缩js
uglify:{
yasuo:{
options:{
mangle:false //压缩代码，参数不改变
},
expand:true,
src:"src/*.js",
dest:"dest",
rename:function (dest,src) {
return dest+"/"+src.replace(".js",".min.js")
}
}
},
// 压缩图片
imagemin: {
dist: {
options: {
optimizationLevel: 3 //定义 PNG 图片优化水平
},
files: [{
expand: true,
cwd: 'img/',
src: ['*.{png,jpg,jpeg}'], // 优化 img 目录下所有 png/jpg/jpeg 图片
dest: 'image/' // 优化后的图片保存位置，覆盖旧图片,
}]
}
},
// 合并压缩css
concat : {
css : {
src: ['src/*.css'],
dest:'dest/index.css'
}
},
cssmin: {
css: {
src:'dest/index.css',
dest:'dest/index-min.css'
}
},
// 压缩html
htmlmin: {
dist: {
options: {
removeComments: true,
collapseWhitespace: true
},
files: {
'dest/index.min.html': 'src/index.html'
}
},
dev: {
files: {
'dest/index.min.html': 'src/index.html'
}
}
},
// 检查js语法
jshint: {
all: [
'app/*.js'
],
options: {
browser: true,
devel: true
}
}
});
//告诉grunt我们将使用插件
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-imagemin');
grunt.loadNpmTasks('grunt-contrib-htmlmin');
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-contrib-cssmin');
grunt.loadNpmTasks('grunt-contrib-jshint');
//告诉grunt当我们在终端中输入grunt时需要做什么（注意先后顺序）
grunt.registerTask('default', ['concat','cssmin','imagemin','uglify','htmlmin','jshint']);
};
