Safety for a production env

[rodolphoasb]

Hey, first I would like to say thank you for all your work on this. The lib looks amazing.

I was wondering what are the core technologies under the hood, it seems like we are not using puppeteer right?

I know it's impossible to garantee full stability with a non oficial API, but I would like your opinion on how much you consider this lib a good fit for a Saas where 50+ clients connect their WhatsApp.

Hi, thank you for your kind words!

seems like we are not using puppeteer right?

It depends - there're few engines and 2 of them use puppeter under the hood, so it looks like a usual WhatsApp Web instance from Meta perspective.
NOWEB engine uses direct connection via websockets, so you should be more accurate when dealing with that, but it's not hard, actually.

It's pretty real with a proper infrastructure preparation.
I'd suggest few things here:

1. Run about 5 sessions per container if you're using WEBJS engine and about 5-10 for "NOWEB*. It'll keep most of clients stable if something goes wrong with a container. So in you case you'll have to manage 5-10 containers for 50 sessions.
2. Using proxies for sessions - we're going to release simple proxy management in July (so you can define a single proxy or proxies list when container starts) and we'll improve it later so you can define proxy during when you start a session via API (it's not possible right now)
3. Use the right pattern for communicating with clients https://waha.devlike.pro/docs/overview/how-to-avoid-blocking/
4. (optional) Get a PRO subscription so I can consult you in Telegram :D

I hope it answers your questions, let me know if there's anything I can help with!
