如何在 gulp 中使用带有 uglify 的 coffescript?

How to use coffescript with uglify in gulp?

我有以下项目结构

assets
--javascripts
----controllers
------somefile.js
------somefile.js.coffee

我想编译 coffescripts 文件 (*.js.coffee),然后合并所有文件,然后缩小它们。

var gulp = require('gulp')

var concat = require('gulp-concat')
var coffee = require('gulp-coffee');
var uglify = require('gulp-uglify')
var gulpFilter = require('gulp-filter');

gulp.task('scripts', function() {
    var coffeeScriptFilesFilter = gulpFilter(['*.js.coffee']);

    return gulp.src(['assets/javascripts/**/*'])
        .pipe(coffeeScriptFilesFilter)
        .pipe(coffee())
        .pipe(coffeeScriptFilesFilter.restore())
        .pipe(concat('application.js'))

        .pipe(gulp.dest('public'))
        .pipe(uglify().on('error', errorHandler));

   function errorHandler (error) {
     console.log(error.toString());
     this.emit('end');
   }
});

不幸的是我遇到了这个错误

Error in plugin 'gulp-uglify'
Message:
    /var/www/gulp/public/application.js: Unexpected token: operator (>)
Details:
    fileName: /var/www/gulp/public/application.js
    lineNumber: 3

没有 uglify 插件一切正常。结果是

console.log('hello!');
var lol = 'asd!';
(function() {
  var test;

  test = function() {
    return "lol";
  };

}).call(this);

uglify 插件可能正在尝试压缩 .js.coffee 文件,但我不知道具体原因。我该如何解决?

Uglify 失败,因为它遇到了 coffeescript。这表明 coffeeScriptFilesFilter 没有捕获所有 *.coffee.js 文件。

给定文件 foo.js.coffee 和 subdir/foo。js.coffee:

// this matches only foo.js.coffee
gulpFilter('*.js.coffee');

// this matches both
gulpFilter('**/*.js.coffee');
