A Beginner's Guide to WebSockets

Perfect introduction for me. Thank you very much. Can't believe you were 18 years old when you did this.

[@builtbywalsh]

This is still amazing, even in 2022. There is now so much wide spread support for websockets, thinking apollo client in particular, that it's nice to get back to fundamentals. Starting with the OSI layer and working our way all the way up the stack to socket IO. Great job!

[@elClubdelas7Cifras]

socket IO 💪

we can clearly admire and respect this young man since he at the young age of 18 he is able to demonstrate great knowledge of networking and computer science concepts while also phrasing it to a room and making it so fluent and understandable. I know he will do amazing things

3:05 Since when is IP above the transport layer?

[@lightninginmyhands4878]

Yes. It is to my delighted surprise this will be in Python

[@WilliardPippenhuffel]

The transport layer is above the internet layer and SSL is in the presentation layer.

9:15 - so infinite scrolling is AJAX?

[@light5068]

yes , you just listen to the scrolling event and request additional data

[@prashantsihag3489]

@@light5068 ah so instead of a button you tie the request with the scrolling event. That seems quite good. Doesn't need websockets anymore than do we ?

[@tikz.-3738]

@@prashantsihag3489 websocket is a full fledged solution to these kind of dynamic websites whereas pinging and ajax are type of workaround but ajax is pretty good too but if u need dynamic content to be accurate at seconds like trading apps then u need websockets

[@tikz.-3738]

@@prashantsihag3489 also websockets is two way connection if u only want to push data and not take any dynamic data from client u should use server side events that's better coz web sockets add a bit more overhead and also can make u prone to attacks as u listen to client and have vulnerabilities

what does it mean when we say that UDP doesnt care about losing data while streaming videos? Shouldn't we get the whole video back? I never noticed a video that isnt well sent and dont understand that implementation example.

[@plugthesnippet6583]

My guess is when a video is playing on lower quality, there was data loss

[@会供価]

I think it’s when a video is buffering or live stream is lagging for a couple second it means u lost data and then it goes right back to good quality. So udp is faster.

[@harshjain4989]

Let's say you are watching video at 60fps. Each second you get 60 frames. However if one of the frames is lost or corrupted then you would not even notice as our eyes can't tell if a single frame is skipped or not. This is what is meant by it doesn't care about losing data.

hi, so he mentions websockets and thrid party API not recommended ? I am thinking about creating a crypto platform that pulls info on real time from binance. Actually, i checked that websocktes are avilable from Binance API data. So, is there any specific challenge about combining websocktes and API requests ?

But how web sockets work? How the browser do this?

[@mariuszdziem8203]

IT just works! :) If you want to know more, download open source Chromium code, and have a look in milions lines of code ;) You need a lot of patience to figure it out :) Browser knows the protocol, and use that protocol, to behave in proper steps. It connects to normal IP number, and knows that protocol deals with websockets. Thats it.

[@tikz.-3738]

U send request to server the server recives it and has a code defined to reply to it when reply is received on front end u can render it as u define on client js, now browser s role is just helping u navigate to site give basic css and show html and run client js rest all is ur code u don't need to look at broweser code and it isn't required to know how websockets work

You are trying to teach this open-source subject (web-design related topics) on the totally closed platform (MAC machines and OS). Is this a joke? If not, then call your video "dedicated to MAC lovers only...not for the vast open source community". I cannot believe a software engineer would use a fashion-designer's tool... unless he works for Apple.

@@peta1001 I built my own desktop pc, and I have a dell laptop. My point stands, you don't know what you're talking about. The device someone is using has absolutely nothing to do with whether or not they can use and promote open source tools.
