我正在开发一个 SBT/Scala Web 项目，我想利用 ES6 功能和前端 JavaScript 层的新模块语法。SBT 有自己的构建系统，我设法调整现有的 sbt 插件来运行 webpack 以使用 babel 构建我的 JS 文件。当前的解决方案有点混乱，但它可以在 sbt 构建系统中工作并存在。

问题是它很慢。每次更改都会创建一个新的 webpack 实例，它会从头开始编译所有内容。

我知道我可以跳出 sbt 构建系统，只在开发阶段单独使用 webpack 来观察和重建我的文件。但在我这样做之前，我想知道是否有一些方法可以加快 webpack 构建过程。

我检查了文档，在我看来，任何可用的缓存都只在内存中处理，这不适用于我的情况。或者是否有某种文件缓存可以在 webpack 构建的单独运行之间存在？例如，我所有的 npm 依赖项大部分时间都不会更改，因此它们可以编译一次，缓存然后简单地包含...

我使用https://highlightjs.org/作为浏览器内（以及静态网站生成器）来突出显示博客和网站的代码片段。我几乎可以肯定它不处理 ES6、ES7、JSX 和 Flow。

我怎样才能更好地突出显示这些新添加的 javascript？

请指教。谢谢 ：）

我有一个简单的 JavaScript 项目，它使用 Babel 将 ECMAScript 6 转换为 ES5，然后需要 Browserify 来利用 ES6 的模块。

因此，我想出了这个Gruntfile.js来编译它：

grunt运行良好，没有任何错误。但是，我收到以下错误：

Uncaught SyntaxError: Unexpected reserved word开export Uncaught SyntaxError: Unexpected reserved word开import

基本上我在主文件中所做的如下：

然后像这样导入它：

我正在根据 ECMAScript 6 编写所有代码。但是，导出/导入似乎不起作用，而是与 JavaScript 保留字冲突（尽管我有browserify.js工作）。

我试图从 ES6 生成器函数的主体中抛出异常，但它没有通过。这是 ES6 规范的一部分还是 Babel 的怪癖？

这是我尝试过的代码（在 babeljs.io 上）：

如果这确实是指定的 ES6 行为，那么发出异常信号的另一种方法是什么？

我正在尝试编写一个可以在运行时使用 webpack 动态加载的模块化组件系统。例如，当用户切换选项卡时，显示新选项卡内容的代码应该仅在用户单击该选项卡时加载。

这是完成此操作的一些代码（非常好，我可能会添加）：

我已经完成了这项工作，但有一个警告。我正在使用 ES6 和 babel-loader 来加载它。包含选项卡的功能、模板、样式等的模块都必须直接包含在应用程序的目录结构中，如下所示（参见：page_components 目录）：

我希望每个页面组件都是它自己的包，带有 package.json，并通过例如： 包含在内require("individial_activity")，用于代码组织。

问题是，webpack 似乎没有node_modules通过任何加载器运行外部模块（例如通过 包含的模块），因此我在尝试加载 ES6 代码时收到有关意外符号的错误。

我尝试了and之类的东西require("babel-loader!individual_activity")，require("babel-loader!individual_activity/path/to/main.js")但无济于事。

我正在尝试做的事情不是正常的做事方式吗？我应该将所有模块的所有代码保存在同一目录结构中吗？我在做一些公然错误的事情吗？

webpack.config.js：

谢谢！

我正在尝试使用 React 0.13 和 ES6 语法编写一个小型 webapp。我正在使用 webpack 和 babel-loader 进行编译：

我在方法中使用 this 变量时遇到问题，在我的代码中的多个地方都出现“这是未定义的”。例如：

在这种情况下，永远不应未定义this变量。但是，我发现问题可能出在 Babel 重写代码的方式上：

这样，在我看来，this变量是指对象文字而不是class。我怎样才能解决这个问题？

我正在尝试扩展 Promise：

然后在派生类上调用static resolve，直接创建resolved promise：

在 traceur 中，这会产生：

在 Babel (run as babel-node --experimental promise.js) 中，它会导致：

我依赖于这个：

Promise 的所有静态方法都支持子类化：它们通过接收器创建新实例（想想：new this(...)）并通过它访问其他静态方法（this.resolve(...) 与 Promise.resolve(.. .))。

来自http://www.2ality.com/2014/10/es6-promises-api.html。

似乎节点检查thison 调用，例如Promise.resolve.call(this, val)是 a Promise，而不是（正确？）Promise 或其派生类（v0.12.0）。

以上是否不再有效，或者没有纳入规范，或者只是没有由 traceur 和/或节点实现？

我从babel.js开始使用 JavaScript ES6 功能，但是我遇到了问题

我目前正在使用 browserify 构建我的应用程序，并使用以下命令进行反应。

现在我想在 babel 中使用一个等效的命令来捆绑我需要的模块，用 ES6 编写到bundle.js中。这不起作用，只是给我一个 ES5 版本的 main.js 文件。

但是我可以使用 babel 将我的 bundle.js 文件编译为 ES6 版本，有 2 个命令

这是将 babel 与 browserify 一起使用的正确方法吗？将您的模块与 browserify 捆绑，然后将捆绑包转换为 ES6？

我有一个 ES6 类，我试图将其导出为模块，但是我收到错误SyntaxError: Unexpected reserved word

汽车.js

我正在尝试像这样使用 Car 模块

main.js

我正在使用带有 babelify 的 browserify 转换为 ES6

我是否正确导出了 Car 模块，还是我做错了什么？
