uWebSockets.js

Hmmm, maybe try optimizing with uwebsockets.js? Works well with Caddy, HAProxy, or NGINX? On cross-domain communications, should be good as long as it's 12-factor where you got a session store / pub-sub mechanism that both servers can use. - https://github.com/uNetworking/uWebSockets.js - https://12factor.net/

Imo it depends on what you mean by "faster". As a node dev, if I'm chasing performance I'd look for libraries with c++ bindings, like uWebSockets[0] for example. NodeJS internal apis also got cluster and worker_threads which are handy when distributing workload in multiple cores. On the other hand if you're talking about faster dev speed, nodejs is ok too since i can reuse some modules in backend and frontend. Of course golang has advantage in terms of types (i abuse assert in nodejs to makeup for this) and performance (i throw money on hardware instead, if really needed), but question is do you really need those right now? The answer greatly varies per project. [0] https://github.com/uNetworking/uWebSockets.js/

I'm currently experimenting with React and WebSockets and they seem to be a perfect fit. No need to write wrappers for Fetch, network errors and reconnects can be handled on high-level, handlers for each message type can be mounted and unmounted on useEffect hooks, all back-end jobs can notify the user in realtime, all session-based client-side data can be updated in realtime (in single or multiple open tabs). I'm also using uWebSockets.js[0] which is great in terms of API design, stability, and performance. Their benchmarks[1] are just convincing. Highly recommend people using ExpressJS / Koa / whatever to try it. [0] https://github.com/uNetworking/uWebSockets.js/ [1] https://github.com/uNetworking/uWebSockets/tree/master/bench...

My codes are written on JS but the sensitive parts are heavily commented with TS types so my vscode intellisense could assist me with correct types. /* * @type {Map<String, Number>} */ const map = new Map(); Like that. Express JS is still shit, koajs and fastify are a little better, I used to use nodejs's internal http and https libraries directly but these days uwebsockets.js is what you'd want since it's mature enough already (used by top crypto exchanges). https://github.com/uNetworking/uWebSockets.js/ And oh it comes with TS types which are cool.
