gulpfile.js:

var gulp = require('gulp');

// gulp.com/plugins/

var rev = require('gulp-rev'); // 添加版本号hash码把文件名修改掉

var revReplace = require('gulp-rev-replace'); // 把index里的引用改成新的

var useref = require('gulp-useref'); //在html里通过注释的方法写一些设置:

//

// <link href="css/one.css" rel="stylesheet">

// <link href="css/two.css" rel="stylesheet">

//

//

// <script type="text/javascript" src="script/one.js" ></script>

// <script type="text/javascript" src="script/two.js" ></script>

//

var filter = require('gulp-filter');// 过滤器

var uglify = require('gulp-uglify');// 压缩js

var csso = require('gulp-csso'); // 压缩css

gulp.task('default', function(){

var jsFilter = filter('**/*.js', {restore:true});

var cssFilter = filter('**/*.css', {restore:true});

var indexHtmlFilter = filter(['**/*','!**/index.html'] ,{restore:true});

return gulp.src('index.html').pipe(useref()).pipe(jsFilter).pipe(uglify()).pipe(jsFilter.restore).pipe(cssFilter).pipe(csso()).pipe(cssFilter.restore).pipe(indexHtmlFilter).pipe(rev()).pipe(indexHtmlFilter.restore).pipe(revReplace()).pipe(gulp.dest('dist'));

})
