gulp

npm install --global gulp-cli
npm init
npm install --save-dev gulp
npm install --save-dev gulp-inject
npm install --save-dev gulp-angular-filesort
gulp早就听说，一直没用，然而随着js越写越多，不用也得用了
这段代码 可以把全部的引入到index里面 妈妈再也不用担心忘记引入js了，打包现在在开发阶段暂时不用，不然会导致查不出错

var gulp = require('gulp');var inject = require('gulp-inject');var angularFilesort = require('gulp-angular-filesort');gulp.task('index', function () {  var target = gulp.src('./index.html');  // It's not necessary to read the files (will speed up things), we're only after their paths:   var sources = gulp.src(['./app/**/*.js']).pipe(angularFilesort());  return target.pipe(inject(sources, {relative: true}))    .pipe(gulp.dest('./'));});
