chat-back | Socket.io를 이용해 만든 채팅방의 서버입니다 | Socket library

I want to get channel Id so I used corvid documentation and follow instructions

First I added wix chat app then I added the following function :

I have such a problem, after reloading the page an error occurs."render function or template not defined in component: anonymous". I think the error is due to socket.io. What does this error do not occur on the local machine, but on the production. dev версия error

server.js

EDIT: The original question asked for a real-time solution. I am not sure this is necessary. It should be about as fast as sending a standard SMS text message.

I want to integrate group chat in my android / ios app. There is a similar question found here, but the answers are old and I would like to see if there are any new / better solutions.

I am currently using multiple AWS services in my app, and would like to keep my chat solution in the same ecosystem. However, if there is a solution outside of AWS that is much easier to implement with good results, I am open to the suggestion.

Based on my research I have come across a couple of possibilties:

• This AWS blog lightly covers using ElastiCache for this purpose

• This LinkedIn slideshow demonstrates the possibility of using AWS IoT

Requirements for my chat:

• Would like to be able to support up to 500 people per chat group

• Usable from the web via online portal that has the same general functionality as the mobile app

• Needs to be scalable to handle thousands of groups

• Needs to handle emojies (cross platform)

• Needs to allow for file transfers. Images and GIFs at the very least.

• Send push notifications to users who have elected to recieve them when they are not currently active in the group

Are either of my possiblities a good fit for my requirements? Which would be the easiest to implement? Are there other, easier solutions inside of AWS? Outside of AWS?
