Answer

replace you ts-node with node where ever you're using and install webpack

add this in you package.json

"prestart": "ng build --prod --no-sourcemap && ngc && webpack",
"start": "node dist/server.js"

Create a webpack.config.js at package.json level and following content

const path = require('path');
const webpack = require('webpack');
const nodeExternals = require('webpack-node-externals');
module.exports = {
    entry: {
        server: './src/server.ts'
    },
    resolve: {
        extensions: ['.ts', '.js']
    },
    target: 'node',    
    plugins: [
    new webpack.NormalModuleReplacementPlugin(/\.\.\/environments\/environment/, '../environments/environment.prod')
    ],
    externals: [nodeExternals({
        whitelist: [
        /^ng2-timeout/
        ]
    })],
    node: {
        __dirname: true
    },
    output: {
        path: path.join(__dirname, 'dist'),
        filename: '[name].js'
    },
    module: {
        rules: [
        { test: /\.ts$/, loader: 'ts-loader' }
        ]
    }
}

add all other libraries in whitelist of externals which are causing errors.

And do npm start
