MEAN: Is it possible to keep an HTTP socket open for the duration of a session?

Question

JavaScript

Some Angular component contains a table that can be updated by users at the same time. Is it possible to use a long open socket in Express for this purpose? Angular returns an Observable from HTTP.get . If Express sends res.write but does not close the res.end connection , can the application work this way? And will the callback in .subscribe of the Observable be called if Express sends res.write ?

Answer 1

IMHO, but web-socket is better for this task.
For ease of implementation, you can use https://www.npmjs.com/package/ws-api
