如何解析angular.js中生成的代码？

Question

我正在尝试用gulp中的代码缩小我的代码我可以创建一个名为_build的文件夹，我在其中优化我的代码，缩小它并返回它uglify  并且显然它已缩小但它不再是angular.js的有效代码，例如：

angularRoutingApp.controller('homeController', function($scope,$state,$http,$timeout,$window,alerta,preload){

到

angularRoutingApp.controller("homeController",function(e,o,i,a,n,r,t)

在这行代码中我将控制器转换为uglify

controllers:[$.uglify()],

这是我的代码：

    gulp.task('minify-js', function() {
      gulp.src('js/*.js')
        .pipe($.uglify())
        .pipe(gulp.dest('./_build/'));
    });

    gulp.task('minify-css', function() {
      gulp.src(['./css/**/*.css'])
        .pipe($.rename({suffix: '.min'}))
        .pipe($.minifyCss({keepBreaks:true}))
        .pipe(gulp.dest('./css/'))
        .pipe(gulp.dest('./_build/css/'));
    });

    gulp.task('minify-html', function() {
      var opts = {
        comments: true,
        spare: true,
        conditionals: true
      };

      gulp.src('./*.html')
        .pipe($.minifyHtml(opts))
        .pipe(gulp.dest('./_build/'));
    });

    gulp.task('fonts', function() {
      gulp.src('./fonts/**/*.{ttf,woff,eof,eot,svg}')
        .pipe($.changed('./_build/fonts'))
        .pipe(gulp.dest('./_build/fonts'));
    });

    gulp.task('server', function(done) {
      return browserSync({
        server: {
          baseDir: './'
        }
      }, done);
    });

    gulp.task('server-build', function(done) {
      return browserSync({
        server: {
          baseDir: './_build/'
        }
      }, done);
    });

    gulp.task('clean:build', function (cb) {
      del([
        './_build/'
        // if we don't want to clean any file we can use negate pattern
        //'!dist/mobile/deploy.json'
      ], cb);
    });

    require('events').EventEmitter.prototype._maxListeners = 100;


    gulp.task('usemin', function() {
      return gulp.src('./index.html')
        // add templates path
        .pipe($.htmlReplace({
          'templates': '<script type="text/javascript" src="js/templates.js"></script>'
        }))
        .pipe($.usemin({
          css: [$.minifyCss(), 'concat'],
          libs: [$.uglify()],
          nonangularlibs: [$.uglify()],
          angularlibs: [$.uglify()],
          controllers:[$.uglify()],
          contservicesapp:[$.uglify()],
          services:[$.uglify()],
          appcomponents: [$.uglify()],
          mainapp: [$.uglify()],
          templates:[$.uglify()],
          directives:[$.uglify()]
        }))
        .pipe(gulp.dest('./_build/'));
    });

我该如何解决？
