Webpack crashed after finding an error in my code

[mpourismaiel]

Using the webpack dashboard plugin, I tried making an error (using a non-existent variable) and I got this log after webpack showed the said error through awesome-typescript-loader:

Complete process:

First green line is from the last successful build.

Can you create a minimal repository that hits the issue and then provide install + error reproduction steps? That would be a great help for us to investigate this more quickly. Thanks!

Looks related to https://github.com/FormidableLabs/electron-webpack-dashboard/issues/52 (at least a comment there).

I posted the comment in #52, thought it might clear that issue somehow. It works after the first build but as I mentioned, on error it crashed.

I created a new webpack config file, really minimum (using webpack-cli) and no crashes were visible. Although new errors did not appear in webpack dashboard.

This is my webpack config file:

const webpack = require('webpack');
const path = require('path');
const DashboardPlugin = require('webpack-dashboard/plugin');

const UglifyJSPlugin = require('uglifyjs-webpack-plugin');

module.exports = {
	entry: './index.js',

	output: {
		filename: '[name].bundle.js',
		path: path.resolve(__dirname, 'dist')
	},

	module: {
		rules: [
			{
				test: /\.js$/,
				exclude: /node_modules/,
				loader: 'babel-loader',

				options: {
					presets: ['es2015']
				}
			}
		]
	},

	plugins: [new UglifyJSPlugin(), new DashboardPlugin()]
};

and my index.js file containing the error:

cost hello = "Hello World!";
