Purpose

NB: Only use this plugin when serving a NodeJS app from Webpack HMR

When using webpack HMR, if you want source maps, you have two options:
- devtool: 'source-map' or equivalent => takes a long time to recompile (when watching changes)
- devtool: 'eval-source-maps' or equivalent => broken stacktraces, wrong files in maps.

Usage

DO NOT REGISTER source-map-support when using this plugin.

``
const webpack = require('webpack');
const HmrEvalSourceMapDevToolPlugin = require('webpack-hmr-sourcemaps');

module.exports = {
// [...]
devtool: prod ? 'source-map' : false,
plugins: [
...prod ? [] : [
new webpack.HotModuleReplacementPlugin(),
new HmrEvalSourceMapDevToolPlugin({
columns: true,
module: true,
})
],
]
}
