i want to develop a chat like application for my organization. what would be the best production stack for that
Good to start with NodeJs later on you can plan for scaling which depends on your usage and response.
If you want to build it quickly, go for Firebase/Firestore. If you need more control and needs good scaling, go for NodeJS + Postgres in the back-end. For front-end, you can use ReactJS and later on NextJS
If you want build it with short time so you can go with firestore/firebase.

I have built one with firebase realtime database as the storage, Nodejs for backend and angular for front end.
