Hey, George

TL;DR PostgreSQL + Django + React.js.

A few notes about Django: * Django includes own ORM which is able to work with SQL databases. In this case, you're able to use any SQL storage like a PostgreSQL / MySQL / etc., but you can't use MongoDB. * Django is synchronous web-framework. If you want to use asynchronous operations in the database, you have to choose another tool (aiohttp for Python or fastify.js for Node.js). * Django is stable. You don't need to worry about data consistency, etc. * Django-Rest-Framework is a great library for handling REST API requests. * django-channels is a library for handling WebSocket connections. * GraphQL is a great thing, but it requires additional knowledge for using it. (especially, performance knowledge).

A few notes about Node.js: * You have to choose Node.js web-framework. Node.js includes a lot of web-frameworks like a express.js, hapi.js, fastify.js, etc. * Node.js applications are asynchronous. It can give you additional performance. * You have to know about data consistency inside your own application. * You're able to use MongoDB or any SQL database because npm includes a lot of libraries that can work with databases. * You're able to use GraphQL because Node.js is a better choice for GraphQL. * You don't need to use additional libraries for handling REST and WebSocket connections.

So, my conclusion is using Django + PostgreSQL + React.js. For this stack, you can get more stability. If you need to get more performance, you have to think about some asynchronous languages (like a Node.js).

Take a look at Flask + SQLAlchemy + PostgreSQL + React.js. SQLAlchemy is a better ORM than Django-ORM.

I hope, it's useful for you :)
