How to update the data for all the users on a POST request

[faisalsayed10]

Hi,
Suppose there's a user A and B.
I have a database which contains a list of posts. All these posts are displayed on the homepage of my website.
Suppose, user B makes a POST request to my database and creates a new post.
Eg:

await axios.post("/api/post", data)

So now I want the data (which is displayed on the homepage) to be updated for user B as well as user A using swr. Now the thing is, I don't want to revalidate the data on focus or interval. If user A is looking at the browser window, the data for them should update right away in front of his eyes and should not require him to switch tabs or anything. How can I implement this? I'm searching this for hours and haven't found any answer. This is basically optimistic UI but for each and every user?

I have looked up on many examples but according to me, its only updating the data for the user who is actually making the POST request and not for other users.

Why that ? How would you proceed to do what you want with any other tool / library anyway ?

Hmm... This can be done with sockets only i think. I was wondering if it was possible the same way with swr

If you need something instant then yes use websockets (if available, depending on the framework you use).
Otherwise, swr is good enough as a ui-refresher.
