Question

我正在尝试创建一个gulp任务，它将从ES6模块生成的代码转换为（使用CJS），并使用browserify将其转换为单个文件。我有以下代码： -

var gulp = require('gulp');

var browserify = require('gulp-browserify');
var es6transpiler = require('gulp-es6-module-transpiler');
var rjs = require('gulp-requirejs');


gulp.task('jscompile', function () {
    gulp.src('./app/scripts/**/*.js')
        .pipe(es6transpiler({
               type : "cjs"
            }))
        .pipe(gulp.dest('./dist'))
        .pipe(browserify(
            './dist/app.js'
        ))
        .pipe('dist');
});

但是，我一直收到以下错误： -

C:\dev\temp\angulargulp>gulp jscompile
[gulp] Using gulpfile C:\dev\temp\angulargulp\gulpfile.js
[gulp] Starting 'jscompile'...
[gulp] 'jscompile' errored after 5.48 ms Object dist has no method 'on'

我是CommonJS，Node和Gulp的新手，如果这是一个愚蠢的问题，请道歉。

感谢。

修改我有以下文件： - 应用程序/脚本/ MyController.js

var MyController = function($scope, MyService, $http) {
    $scope.doSomething = function() {
        console.log("Yo");
    }
}

export default MyControllerDef = [ "$scope", "MyService", "$http", MyController ];

应用程序/脚本/ app.js

/*jshint unused: vars */

import MyControllerDef from 'MyController';
import GetBookingServiceDef from 'bookingsummary/services/GetBookingService';

angular.module("test")
      .controller("MyController", MyControllerDef);

angular.module("test")
      .services("GetBookingService", GetBookingServiceDef);

应用程序/脚本/服务/ GetBookingService.js

"use strict";

var GetBookingService = function($rootScope, $http) {
    return {
        retrieveBooking : function() {
            return $http.get("/scripts/dummyValues/booking.js").then(function(inResponse) {
                if (inResponse.data instanceof String)
                    return JSON.toJSON(inResponse.data);
                 return inResponse.data;
            });
        },
        notifyBookingUpdates : function(data) {
            $rootScope.$emit("bookingsummary.update", data);
        },
        listenToBookingUpdates : function(bookingUpdateFn) {
            $rootScope.$on("bookingsummary.update", function(e, data) {
                bookingUpdateFn(data);
            });
        }
    };
};

export default GetBookingServiceDef = [ "$rootScope", "$http", GetBookingService ];

根据以下反馈，我修改了我的gulp脚本： -

var gulp = require('gulp');

var browserify = require('gulp-browserify');
var es6transpiler = require('gulp-es6-module-transpiler');

gulp.task('jscompile', function () {
    return gulp.src('./app/scripts/**/*.js')
        .pipe(es6transpiler({
               type : "cjs"
            }))
        .pipe(gulp.dest('./dist'))
        .pipe(browserify())
        .pipe('./dist/finalapp.js');
});

这已将错误修改为： -

C:\dev\temp\angulargulp>gulp jscompile
[gulp] Using gulpfile C:\dev\temp\angulargulp\gulpfile.js
[gulp] Starting 'jscompile'...
[gulp] 'jscompile' errored after 5.24 ms Object ./dist/finalapp.js has no method 'on'

        throw er; // Unhandled 'error' event

像这样使用：

    .pipe(browserify())
    .pipe(gulp.dest('./dist/app.js'));

请注意，browserify插件会将对象{}作为选项。不是作为目的地的字符串。查看gulp-browserify plugin了解如何使用它。

ES6 transpiler + browserify + gulp
