gulp使用指南

2.gulp安装 http://www.ydcss.com/archives/18

3.目录结构

4.index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script>
</head>
<body>
    <input type="button" id="button1" value="Click">
    <script src="js/index.js" ></script>
</body>
</html>

5.index.js

$(function () {
    $('#button1').click(function () {
        alert('button1');
    });
});

6.config.js

var src = '../src';
var dest = '../dist';
var config = {
    js: {
        src: src + "/js/**/*",
        dest: dest + "/js",
        rev: dest + "/rev/js"
    },
    rev:{
        revJson: dest + "/rev/**/*.json",
        src: src + "/*.html",
        dest: dest
    }
}
module.exports = config;

7.gulpfile.js

var gulp = require('gulp');

//使用gulp-uglify压缩javascript文件，减小文件大小。http://www.ydcss.com/archives/54
var uglify = require('gulp-uglify');

//根据静态资源内容，生成md5签名，打包出来的文件名会加上md5签名，同时生成一个json用来保存文件名路径对应关系。http://www.cnblogs.com/1wen/p/5421212.html
var rev = require('gulp-rev');

//这个插件就是从manifests中获取静态资源版本数据, 该数据由不同的流产生, 并且替换html中的链接。 http://blog.csdn.net/hayleyxia/article/details/46969711
var revCollector = require('gulp-rev-collector');

//优雅的异步处理任务。https://www.npmjs.com/package/gulp-sync
var gulpsync = require('gulp-sync')(gulp);

var config = require('./config').js;
var configRev = require('./config').rev;


gulp.task('js', function() {
    return gulp.src(config.src)
        .pipe(uglify({mangle: false, compress: {properties: false}, output: {quote_keys: true}}))
        .pipe(rev())
        .pipe(gulp.dest(config.dest))
        .pipe(rev.manifest())
        .pipe(gulp.dest(config.rev));
});

gulp.task('rev', function () {
    return gulp.src([configRev.revJson, configRev.src])
        .pipe(revCollector({replaceReved: true,}))
        .pipe(gulp.dest(configRev.dest) );
});

gulp.task('default',gulpsync.sync(['js', 'rev']),function () {

});

9.压缩后的index.js

$(function(){$("#button1").click(function(){alert("button1")})});

10.遍历所有html，替换文件命名后的效果
