I want to develop for a client where he will select a group of employees and everyone can edit a file via web. He wants style as it does in Google Drive Docs, where the person types and the other person who is on another computer can see it in real time by typing or inserting an image.
I understand that this can be done in Ajax, but I am very lazy. Are there any examples in Ajax itself and how far could it impact the server, since the system is multiuser?
You have not mentioned the technology you are using. however MeteorJS falls as a glove to solve your problem.
But regardless of the set of technologies you adopt, the best performing solution is to use communication with Server using WebSockets and Front-End some library Reactive.
On the Server side, I'll list some examples:
As for Front-End , I also have some suggestions.:
An alternative to using WebSockets would be PouchDb with CouchDb and do a Replicação dos Dados as well as escutar todas as alterações in the Document, but in this case, you would have to do a finer configuration for the amount of synchronizations.
