In this session we will discuss about creating a real time chat application using AWS API gateway.

Amazing tutorial! This is very underrated channel. Your content is really good. I never thought that it will be possible to implement end to end websocket chat application under 15 minutes, I always thought that it will be complicated. But you made it really simple. :)

Hi, it is very strange you have so few subscribers... You make very high quality videos and use very good examples. It is real helpful to watch your videos. Thanks a lot! I wish you good luck!

This really helped me out! Great quality, keep going :)

[joejiang]

Love the video! It is of very high quality

[KarimFayed-oyoo]

Great video it's really helpful!! But what if I wish for messages from terminal 1 only to be sent to terminal 2 and from terminal 3 only to be sent to terminal 4 like private chats on an app.

if i had to only make this peer to peer chat, rather than a brodcast chat, will this similar outlined process via websockets lambda be an ideal practice to go through, if yes, what changes should be made in the vedio, or if you can create one such vedio about same about peer to peerchat, that would be so good.

Nice tutorial! What did use to design the diagrams?

[rushikeshdhajal]

Nice tutorial !! Very informative .. Can you please confirm that can we do this in free tier account ??? Or is there any charges if we create this environment ??

[nainaarabha]

I have one doubt. Can we host multiple kafka producers in one ec2 instance?

[Matt-kcxr]

If the Websocket is public facing how do you deal with authorisation of users? As I am aware you cannot use custom headers in websockets to securely transfer the JWT.

Hi, ! great video. Do you know the easiest way to handle abrupt disconnections? Because when this happends i get an empty event in disconnect lambda function (so i can't delete the connectionid from the dynamodb). And btw, do you know if there is a way of brodcast a msg to all the connected clients without having to manually store the connectedId's? Thanks!!

[gabrielgarciamartinez]

It shows me the error 502 bad gateway when i try to connect to the api. Do you know why this can happen?
Edit: i think It will run if i change the return of the lambda fuctions

Thank you for this. Is this free or is there a charge? If there is a charge, how much is it?

[suryaprakashsharma]
