Question

我正在将应用程序从angular.js（版本1）迁移到Vue.js版本2.4。

我正在从在开发模式下提供原始Javascript文件转向使用Webpack，babel和.vue，它们提供已处理的Javascript文件。 Webpack和Vue.js对我来说都是新手。

当代码中发生异常时，Vue.js或Webpack会拦截错误并打印出无用的堆栈跟踪。以下是一个例子。

我猜测如果Vue.js / Webpack没有拦截异常，我可以在浏览器中看到堆栈跟踪以及发生异常的代码。

是否有使用Vue.js有效使用浏览器调试器的指南？

我正在使用Firefox并拥有vuedevtools 2.5.9。

Answer 1

问题似乎是Firefox不提供与Vue.js的交互式堆栈跟踪，或者我的构建有问题。

我切换到Chrome并获得了一个非常实用的工具。堆栈跟踪显示原始文件中的信息。我可以点击进入该文件。我可以设置断点，虽然线条似乎是关闭的（由于我确定源数据映射）。

一旦我有功能配置，我对文档的迫切需求就消失了。

更好的堆栈跟踪
