It has the necessary packages for what you need, in addition to optimizing your time with what is needed.

Node.js is great but if I had a choice for something like this I would pick Elixir and Phoenix. They have LiveViews and channels which be one step up then the other 3 plateforms. It will also scale better and respond faster. Last will probably far less code as well.

Node.js is the perfect tech to real-time features like chats, forums, quizzes and polls. Additionally it has great support for objects storage like Mongodb and its important for file media management.

I would suggest you to pick the right stack for the right purpose. My suggestion would be to go for Microservices approach and break your app into smaller pieces according to the type of functionality like you mentioned above. E.g if you would be expecting the high traffic on you platform, then Node.js can be used as the endpoint there to handle that traffic. Normal form processing can be done in Laravel but I would not suggest codeigniter as managing code is difficult there.

So this way you can decide do architecture you app and can use the best of the feature from all the languages. Even it would be easier for you to manage your app based on the functionality and team who will be working on that. Hope you would like my suggestions.
