Websockets - Locally Hosted Alternative for Pusher (Now Free)

matteocontrini

I just noticed an issue that started to appear after swapping the websocket server: it seems that the WebSocket connection is not attempted anymore when you're idle, after a while.

Here's what I see:

The connection was closed and nothing happened after that, so real-time features stopped working.

Kyrne

matteocontrini This is actually intended, literally a feature not a bug. Stale connections staying open is a part of the memory leak issue from the main server. Closing connections after a while is an industry-standard practice with websockets.

There's no good solution that works for everyone. If we leave the connection (channel) open after the client stops responding, the server will be eventually bogged down with connections and we can't guarantee the client won't attempt to open a new connection as opposed to the old one when it reconnects. If we close the connection after no response, the client will lose real-time features until they refresh the page.

Kyrne @matteocontrini this is also the same way that websockets operate in NodeBB. Very much a standard.

Kyrne I don't think I get it. Why does the client stop responding? The client is alive and should respond/re-open the connection. I see real-time features stop working "permanently" after a couple of minutes just by leaving the page open, which makes the feature quite useless, honestly...

I've noticed it too. I've got tab opened for few hours and sometimes it's just lose connection without any notification.

I would expect some "auto reconnect" feature when connection is broken for any reason and flarum tab is still open.

Could be really useful when you using it on mobile or when you sleep your PC. So after reopen browser with flarum tab it can reconnect by itself without requirement of refreshing page.

Also some indication of broken connection would be great. Something like "you are offline now, trying to reconnect..."

Hello, when do you plan to upgrade for Flarum 1.0? Thanks!

[deleted] How could you force it to avoid this error? (shaman79 )

[deleted]

Websocket installed and activated without issue on my newly upgraded Flarum (1.02). Need to test it to ensure it works as planned, but no issues from what I see so far.

luceos

[deleted] it's running on discuss since this morning. No real issues found so far except for ignored discussions showing up on the index.

[deleted]

luceos Yes, I can't find any issues on my site. Seems fine.

luceos

Darkle that's because Kyrne released a new version but hasn't announced it yet.

[deleted]

luceos Guess I just got lucky 🤣

Websocket stops working after a few page refreshes. The following error pops up in the browser.

Kyrne

mekici this looks like a setup issue and not related to websocket. Can you try a different port like 2053?

Kyrne

2.7.0

Fixes [deleted] user bug
Fixes user discussion pages showing a refresh when its not a discussion of theirs
- This is actually a new feature as well, those pages will refresh on new discussions
Updates now work on specific tag pages again & tags page fixes
Removed all loading time for updates (the button will still be there but it is instant)
Other stuff

There is a one-time purchase here - https://extiverse.com/extension/kyrne/websocket

It's probably not been updated on Discuss yet.

[deleted] It's probably not been updated on Discuss yet.

Discuss switched to blomstra/realtime last night. I'm working on some of the bugs as we speak. I'll create a discussion about it soon.

luceos blomstra/realtime

Is it absolutely free? Can you share any link for any thing please I listened about this but I am unable to find at the moment.

yes he shared a github link which @Kyrne sir used for the websocket extensions said luceos sir. Me too want that github link so i can figure if i can do something. i can't afford $60 for a extension 😅

No, blomstra/realtime is also a premium extension.
