Webpack - bundle all node modules except one in angular universal - node.js

Question

I made a webapp with angular. I want server side rendering with Angular Universal.
The best way to build such a server is by using webpack, this is the standard configuration which works for most of the cases:
const path = require('path');
const webpack = require('webpack');
module.exports = {
entry: { server: './server.ts' },
resolve: { extensions: ['.js', '.ts'] },
target: 'node',
externals: [/node_modules/],
mode: 'none',
// this makes sure we include node_modules and other 3rd party libraries
output: {
path: path.join(__dirname, 'dist'),
filename: '[name].js'
},
module: {
rules: [{ test: /\.ts$/, loader: 'ts-loader', exclude: /server-local/ }]
},
plugins: [
// Temporary Fix for issue: https://github.com/angular/angular/issues/11580
// for 'WARNING Critical dependency: the request of a dependency is an expression'
new webpack.ContextReplacementPlugin(
/(.+)?angular(\\|\/)core(.+)?/,
path.join(__dirname, 'src'), // location of your src
{} // a map of your routes
),
new webpack.ContextReplacementPlugin(
/(.+)?express(\\|\/)(.+)?/,
path.join(__dirname, 'src'),
{}
)
]
};
But I got a problem: I use the node module pug-mailer in my server and it uses uglify-js as dependency and not dev dependencies. Webpack has no support in bundling uglify-js, so the only way I found to solve this problem was this:
const nodeExternals = require('webpack-node-externals');
module.exports = {
externals: [nodeExternals()],
... //the rest is unchanged
};
But it cannot be accepted: with this, all node_modules are not bundled and I have to keep the entire node_modules dir in my production server.
Is there a way to bundle all the node_modules in only one file except for uglify-js?
The result I want is this:
dist
----server.js //built with webpack, contains all node_modules except uglify-js
----other dists folder
node_modules
----uglify-js //Only this dependency in node_modules
