Simple implementation of notifications from the server to the browser?

Question

PHP

Let's say I'm doing a chat.
You need to notify clients when certain events occur.
The main site is written in PHP, and this is where the events appear.
The easiest way I see is:
1) On Node.js (socket.io), write a server (and put it behind nginx), which will be connected to the browser via WebSocket.
2) When an event occurs in the PHP part of the project, we send a message to rabbitmq.
3) If there is a message in rabbitmq, we send it to the Node.js daemon to the necessary clients in the browsers.
4) Monitor the Node.js server to the supervisor.
I don't like the technology zoo for this task.
How sooner can you?

Answer 1

And what exactly in a set of technologies confuses? Well, as an option, you can replace node.js with Ratchet, -1 YP will be in the list.
So in fact, do not subtract, do not add.

Answer 2

easier - longpoling.
on the client using ajax send a request to the server. Set a timeout of 1 minute. On the server, you make a loop that returns a value if there are changes + sleep(1) in the iteration. Well, set the time - as convenient. in case of changes - send data - ajax accepts and notifies.

Answer 3

The simplest is a socket. It will be nowhere easier.

Answer 4

For me, the easiest way was to use server sent events
For web sockets, in principle, node js is not necessary, the php script can also be made to be a demon.
And communication between the daemon and the site is easier, yes, through rabbitmq.

Answer 5

As I understand it, you don’t want to put the node in the zoo, then take Go, it’s simple, beautiful, a minimum of dependencies, it will be easier to scale

Answer 6

You can try Star.Comet, it's just because you will only have php and js on your side, and everything else is already ready and works in saas mode.
