SL realtime web app

Question

hello fellows,
i already seen an example with NodeJS & Socket.io and others but is it possible to implement a simple realtime web app (ex. weather) in SL playground?

thanks in advance

Answer 1

thanks guys,
but do u have any example of that?

Janning⭐ i failed to see realtime update with JavaScript in ur Ajax Test web code

Answer 2

yup and I tried several solutions too, found them from websites & executed from my pc browser, yet none of them works either in SL playground nor W3schools TryIt... However, it does work if I save and run them in an HTML file. why can this be?

Answer 3

If it's resource intensive and SoloLearn has a large user base, I think the logical conclusion would be that implementing such a feature would not be a sustainable business decision in the long run. That being said, a weather app doesn't have to be real-time in that it opens up a direct connection to the server -- just have it pull new info on refresh.

Answer 4

It's possible s/he could be talking about JavaScript, but s/he already uses JavaScript in the Code Playground and the question was about real-time web apps (I thought).

Answer 5

Website and web app are technically different.

Answer 6

Janning⭐ that sucks :/ i cant think for any other ways

Answer 7

Yeah, I feel you. It's rough. I think the Code Playground is really great for testing out small things and showcasing snippets, but not ideal for substantial projects (although I very much admire the amount of code some SoloLearners have been able to cram into some of their projects). Still grateful for having it though! 😊

See my first comment? (You might have to Tap to Load More at this point.)

I've found that w3schools TryIt is more broken than Code Playground.

Answer 9

use intervals for updating maybe?

Answer 10

Janning⭐ i think hes talking about js and js runs on client side so i dont think it would hurt sololearn

Answer 11

Janning⭐ you can definetly make a real time website with javascript im sure about that

Answer 12

Janning⭐ i know, the thing i was trying to explain wasnt that I mean, I was trying to explain you can make a real time app in sololearn with javascript, when i said website i was talking about web codes

Answer 13

No problem. When you say real time, what's your alternate definition?

Answer 14

Janning⭐ i mean you can make connections with ajax in js and set an interval for auto-updating

Answer 15

AJAX requests in Code Playground error out on my phone, but maybe your platform supports them?

Answer 16

Amirreza Odoumi, the point I was trying to make with the code sample is that real time updating doesn't work in Code Playground.
