I haven’t tried movies although for music I think it sounds amazing. It’s meant to be a studio monitor so it lets me hear all the details. I’m not an audio expert at all but that does mean it’s meant to be somewhat “neutral”, and I’m not sure what’s ideal for movies. For my use case if it’s not obvious I use it to monitor my mic to make sure it’s not recording things it shouldn’t, and to generally hear its quality in realtime as well as in post production

In 30:57, won't the setTimeout actually kind of bombard the clients with multiple "isTyping = false"? For each time we're calling the "isTyping = true" event we're creating a new setTimeout and actually de-referencing it afterwards, without killing the original first. (maybe this is covered later in the video, but I wanted to mention it before I forgot, sorry if it is already covered)
@mariusespejo

Sorry been a while since I wrote the code but I think you’re right, probably ideal to clearTimeout, I think I intended to do that that’s why we have the timeout variable defined. Basically we’re just trying to debounce there. Good eye!

When you are working on REST API you can document your controllers using Swagger but what alternatives do we have while workig on sockets?
@mariusespejo
@mariusespejo 2 жыл бұрын
There’s a thing called swaggger-socket but that’s only if you were attempting to do REST over websockets, which is probably uncommon. Other than that I’m not sure there’s any common standard for how to structure websockets so there likely isn’t much swagger-like solutions. You could always make your own custom documentation though

I'm torn between sending the real-time data in the payload and just publishing a new "resource" created event and having the clients that are subscribed to that event re-fetch the data for that resource. On one hand, you save having your clients send multiple requests for the resource by including the data in the payload. On the other hand, by forcing them to re-fetch the data, you get to have one source of truth. Thoughts?
@mariusespejo
@mariusespejo 2 жыл бұрын
I’m sure there are more details to your use case but my gut reaction is that: if you’re already using websocket, meaning you have a persistent connection, why wouldn’t you just send the data directly? You still have one source of truth which is the server who now says “hey all you clients this is now the current data!” And clients could react and update immediately. However your other idea of simply publishing a trigger, it still means that each client still needs to spend additional time to fetch data which sounds like could have been available to them at the same time they got the trigger. However, there is nothing inherently wrong with that approach. If it’s because you’re just trying to reuse APIs, that makes sense to me

Hello. How do you store connected users on the server in the real applications?
@mariusespejo
@mariusespejo 2 жыл бұрын
The underlying websocket library you use like socket.io usually will take care of keeping track of which clients are connected. You just need to build a way for your server to identify who the user is on that client, e.g. basically auth. Put those two together and you’ve got your list of connected users.

thanks so much, and how can we authorize connected users?
@mariusespejo
@mariusespejo 2 жыл бұрын
I have some videos on auth. The fundamentals are all the same, you need a way to identify the user (e.g. perhaps upon connection require a login event, or do login via REST prior to allowing a connection). Once you can identify which user is dispatching an event, then it’s up to you how to do authorization, you can pull the user record and check they have permissions etc. Generally with nest you can utilize guards to do those checks. Few videos about that in the channel

Ah! I actually didn’t even know that was a thing, today I learn from you, thanks! I’ll look into it and maybe form opinions about it first. But at quick glance, it looks like it’s not bidirectional so the use case is limited to communication only coming from server. Also there is a hard limit of 6 connections per browser, unless it’s on HTTP/2 … that sounds pretty limiting. I could see this being useful for push notifications though!

thanks for your excellent tutorial, but I'm kind of tired of people explaining the same real time chat application example. I cannot find a way to connect to an external webSocket from an exchange for example to retrieve book orders, and there is not a single tutorial on consuming an already existing webSocket. So frustrating.
@mariusespejo
@mariusespejo Жыл бұрын
It’s important to look past the “it’s just another chat app” and actually learn and understand the underlying fundamentals required to engineer a more specific problem, e.g. if you’re putting together your own real-time feature. Your use case however is about integration with a 3rd party. Any external api generally should include usage docs, you should rely on that not tutorials. If it doesn’t have docs… reach out to the devs
