Webpack build fail when adding a specific external lib - node.js

Question

It happens on a build for server side, i am already using a lot of external modules and everything worked great until now.
I am trying to add the module auth0-js and the error happens when i add the import on this lib var crypto = require('crypto'); TypeError: require is not a function.
Here is my webpack config (for server side):
const path = require('path');
const webpack = require('webpack');
const StatsPlugin = require('stats-webpack-plugin');
module.exports = {
entry: './handler.js',
target: 'node',
profile: false,
output: {
path: path.resolve(__dirname, '../dist-server'),
publicPath: '/',
filename: 'handler.js',
libraryTarget: 'commonjs'
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
include: path.resolve(__dirname, '..'),
use: 'babel-loader'
},
{
test: /\.pug$/,
use: 'pug-loader'
}
]
},
plugins: [
new webpack.DefinePlugin({
__CLIENT__: false,
__SERVER__: true
}),
new StatsPlugin('stats.json', {
chunkModules: true,
exclude: [/node_modules[\\\/]react/]
})
],
resolve: {
modules: [
path.resolve('./src'),
path.resolve('./node_modules')
]
},
devtool: 'source-map'
};
My .babelrc file is:
{
"presets": [
"react",
"latest"
],
"plugins": [
"transform-object-rest-spread",
"transform-runtime"
]
}
I tried to remove the exclude node_modules but i get other errors.
I am curious to know how a single library can break everything, what should i do?
