Я собираю с помощью rollup
в package.json в scripts добавляем

"build:server": "rollup --config server/rollup.config.js",

в package.json в dependencies добавляем

"rollup-plugin-json": "^4.0.0",
"rollup-plugin-terser": "^5.3.0",
"rollup-plugin-typescript2": "^0.26.0",

rollup.config.js

import typescript from 'rollup-plugin-typescript2';
import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import json from 'rollup-plugin-json';
import pkg from "../package.json";
import copy from 'rollup-plugin-copy';

export default [
    {
        input: 'server/server.ts',
        plugins:[
            typescript({
                typescript: require('typescript'),
                "declaration": false,
                "module": "esnext",
                "noImplicitAny": false,
                "target": "es5",
                "skipLibCheck": true,
                "allowSyntheticDefaultImports": true,
                "lib": ["dom", "es6"],
                "typeRoots": ["node_modules/@types"]
            }),
            resolve({
                browser: false,
                main:true
            }),
            json(),
            commonjs(),
        ],
        external: [
            ...Object.keys(pkg.dependencies || {})
        ],
        output: {
            file: 'dist/server/server.js',
            format: 'cjs'
        }

    },
