gulp之自动化压缩合并加版本号

这个方案主要是为了实现js/css/image的压缩合并、自动添加版本号、自动加浏览器前缀和压缩html。

• gulp-sequence //顺序执行任务
• gulp-csso //css压缩
• gulp-jshint //js检查
• gulp-uglify’), //js压缩
• gulp-imagemin //压缩图片
• gulp-htmlmin //压缩html
• gulp-clean //清空文件夹
• gulp-rev //更改版本名 md5后缀
• gulp-autoprefixer //加浏览器前缀
• gulp-rev-collector //gulp-rev 的插件，用于html模板更改引用路径

目录结构

|- root
|    |-dist  //此目录为下面生成的
|         |-css
|         |-js
|         |-images
|         |-rev
|         |-index.html
|    |-node_modules
|    |-src   //资源目录
|         |-css
|         |-js
|         |-images
|         index.html
|     gulpfile.js
|     package.json

gulpfile.js文件

//清空文件夹gulp.task('clean', function(){    return gulp.src('dist', {read:false})               .pipe(clean());});

//压缩css/加浏览器前缀gulp.task('css', function(){    return gulp.src('src/css/*.css')        .pipe(autoFx({            browsers: ['last 2 versions', 'Android >= 4.0']        }))        .pipe(csso())        .pipe(rev())        .pipe(gulp.dest('dist/css'))        .pipe(rev.manifest())        .pipe(gulp.dest('dist/rev/css'));});

//压缩jsgulp.task('js', function(){    return gulp.src('src/js/*.js')        .pipe(uglify())        .pipe(rev())         .pipe(gulp.dest('dist/js'))        .pipe(rev.manifest())        .pipe(gulp.dest('dist/rev/js'));});

//压缩imagegulp.task('image', function(){    return gulp.src('src/images/*.{png,jpg,gif,ico}')               .pipe(imageMin({                    optimizationLevel: 5,                    progressive: true,                    interlaced: true,                    multipass: true               }))               .pipe(rev())               .pipe(gulp.dest('dist/images'))               .pipe(rev.manifest())               .pipe(gulp.dest('dist/rev/images'));});

//改变css引用路径gulp.task('revCss',function(){    return gulp.src(['dist/rev/**/*.json','dist/css/*.css'])               .pipe(revCollector({                    replaceReved: true           }))               .pipe(gulp.dest('dist/css'));});

//改变html引用路径gulp.task('rev', function(){    return gulp.src(['dist/rev/**/*.json','src/*.html'])               .pipe(revCollector({                    replaceReved: true               }))               .pipe(htmlMin())               .pipe(gulp.dest('dist/'));});

gulp.task('default', gulpSequence('clean', 'css', 'js', 'image', 'revCss', 'rev'));    //按顺序执行任务
