I always wanted to play with websockets and ktor but never had any idea on what to build, this video was my destiny, thanks!

[CineTechGeek]

Can you run ktor from an Android app?
So, for example start a android app, it becomes the server?

[nymexe]

Pretty good job 👍 I have been waiting for a video about web-sockets for a long time 😀

[TVHovna]

Wow, really broad topic you've covered. Will watch soon :)

[raymondmichael]

Thanks, I've been trying to learn kotlin so much, your channel is a good place.
though I find it hard to swap databases like from room to realm; hopefully one day you'll cover that too.
Thanks buddy, stay healthier

More on Websocket-related videos!

Philipp a question, is it possible if I use Ktor (so that I can use the dependency ktor-server-wrbsockets) just for the real communication between the server and client (kotlin android) and to have another API written in another language (e.g. Node.js) as the main API that is connected to database?

Thank You for such an amazing tutorial. It was really insightful with lots of learning

In the TicTacToeGame class, do you need to assign delayGameJob in the init block like ""delayGameJob = Since you only assign it when start a newGame, but not on the init block, therefore, it may cannot cancel the first time job.

hey @PhilippLackner please make a video to deploy ktor web application on xaamp or apache please

[venkateshlingampally]

I have used that play button only to play the android project on the android device. Now I'm also using it for the Backend LOL. Actually, it feels like an android project we are working on but not that's crazy.

[nymexe]

Why are you still using the legacy version of defining dependencies/plugins in the project-level build file? I think the Gradle team did a pretty good job on it 😀

[ShashankYadav-vgtz]

Amazing tutorial philipp❤ can you tell me where can i learn more on websockets like resources or docs?
