功能描述

使用方法

例1：基本使用

var gulp     = require('gulp'),
    uglify   = require('gulp-uglify'),
    pump     = require('pump');

gulp.task('jsmin', function(cb) {
    pump([
        gulp.src('src/js/index.js'),
        uglify(),
        gulp.dest('dist/js')
    ], cb)
});

例2：压缩多个JS文件，输出至指定目录

var gulp     = require('gulp'),
    uglify   = require('gulp-uglify'),
    pump     = require('pump');

gulp.task('jsmin', function(cb) {
    pump([
        gulp.src(['src/js/demo1.js', 'src/js/demo2.js']),
        uglify(),
        gulp.dest('dist/js')
    ], cb)
});

例3：使用通配符“!”，“”，“*”，“{}”进行模式匹配

var gulp     = require('gulp'),
    uglify   = require('gulp-uglify'),
    pump     = require('pump');

gulp.task('jsmin', function(cb) {
    pump([
        gulp.src(['src/js/*.js']),
        uglify(),
        gulp.dest('dist/js')
    ], cb)
});
