javascript - 我如何使用 broccoli.js 获得一个简单的文件树来连接

Question

我正在努力思考 broccoli.js但我遇到了一个错误。如果你看我的GitHub repo ，你会看到我有一个 brocfile.js 看起来像这样:

brocfile.js

var compileES6 = require('broccoli-es6-concatenator')
var pickFiles = require('broccoli-static-compiler');
var mergeTrees = require('broccoli-merge-trees')


var app = 'app'
app = pickFiles(app,{
    srcDir: '/',
    destDir: 'app-kit'
})

var appJS = compileES6(app, {
    inputFiles: ['/app-kit/**/*.js'],
    outputFile: '/dist/app.js'
})

module.exports = mergeTrees([appJS]);

我收到这个错误:

Built with error:

    at process._tickCallback (node.js:415:13)
    at Function.Module.runMain (module.js:499:11)
    at startup (node.js:119:16)

从长远来看，我想用它作为构建 ember.js 应用程序的起点，所以我创建了一个 github repo .如果你去那里你可以看到我的文件结构。关于我为什么会收到此错误的任何想法？

Answer 1

过去几天我一直在和西兰花搏斗。这对我来说也是新的，但我克隆了您的存储库并通过执行以下操作让 broccoli serve 工作:

1) 我在 loader/loader.js 中创建了一个“loader.js”文件。 loader.js 文件包含 ES6 模块加载器 polyfill 代码，以允许 ES6 模块在非 ES6 浏览器中加载。我从 Broccoli 示例应用程序中获取了文件:https://github.com/joliss/broccoli-sample-app/blob/master/vendor/loader.js

2) 我将加载程序注入(inject)到应用程序树中，并在 compileES6 配置中引用它。 (此选项是错误中的 undefined 值。)

这是为我成功构建的更新后的 brocfile.js。

//brocfile.js

var compileES6 = require('broccoli-es6-concatenator');
var pickFiles = require('broccoli-static-compiler');
var mergeTrees = require('broccoli-merge-trees');


var app = 'app';
app = pickFiles(app,{
  srcDir: '/',
  destDir: 'app-kit'
});

// Reference to ES6 loader
var loader = "loader";

// Squash the loader and app trees into one
var sourceTrees = [app, loader];
sourceTrees = new mergeTrees(sourceTrees);

var appJS = compileES6(sourceTrees, {
  loaderFile: 'loader.js', // This required option was undefined before
  inputFiles: ['app-kit/**/*.js'],
  outputFile: '/dist/app.js'
});

module.exports = mergeTrees([appJS]);

我希望这能帮助您进入西兰花冒险的下一步。
