gulp的插件使用

// 引入插件

        var gulp = require('gulp'),
        	less = require('gulp-less'), //编译less
        	cssmin = require('gulp-cssmin')  //压缩css
        	autoprefixer = require('gulp-autoprefixer'), //兼容css
        	rev = require('gulp-rev'),  //重命名（加密） 解决浏览器端缓存
        	imagemin = require('gulp-imagemin'),  //压缩图片 
        	rename = require('gulp-rename'),  //重命名
        	useref = require('gulp-useref'),  //根据注释     合并或删除html文件中的内容
        	uglify = require('gulp-uglify'),  //压缩js
        	gulpif = require('gulp-if'),  //条件判断
        	revCollector = require('gulp-rev-collector'),  //加密
        	htmlmin = require('gulp-htmlmin');  //压缩html

// 处理css

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

return gulp.src('./public/less/main.less')
	.pipe(less())
	.pipe(cssmin())
	.pipe(autoprefixer())
	.pipe(rev())
	.pipe(gulp.dest('./release/public/css'))
	.pipe(rev.manifest())
	.pipe(rename('css-mainfest.json'))
	.pipe(gulp.dest('./release/rev'));

});

// 图片处理

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

return gulp.src(['./public/images/**/*', './uploads/**/*'], {base: './'})
	.pipe(imagemin())
	.pipe(rev())
	.pipe(gulp.dest('./release/'))
	.pipe(rev.manifest())
	.pipe(rename('image-manifest.json'))
	.pipe(gulp.dest('./release/rev'));

});

// md5名

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

return gulp.src('./index.html')
	.pipe(useref())
	.pipe(gulpif('*.js', uglify()))
	.pipe(gulpif('*.js', rev()))
	.pipe(gulp.dest('./release'))
	.pipe(rev.manifest())
	.pipe(rename('js-manifest.json'))
	.pipe(gulp.dest('./release/rev'));

});

// 压缩html

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

return gulp.src('./views/*.html')
	.pipe(htmlmin())
	.pipe(gulp.dest('./release/views'));

});

// 其它内容

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

	gulp.src(['./api/*', './public/fonts/*'], {base: './'})
		.pipe(gulp.dest('./release'));

});

// 路径替换

gulp.task('rev', ['css', 'image', 'useref', 'html'], function () {
	gulp.src(['./release/rev/*.json', './release/?(views)/*.html'], {base: './release'})
		.pipe(revCollector())
		.pipe(gulp.dest('./release'));
});

 //终极调用
gulp.task('default', ['rev', 'other', 'html']);
