Reconnect when user switches from Wifi to LTE?

[GeoffreyPlitt]

I'm using this in a mobile app, but it would be the same for mobile web.

I use the client to connect to an engine.io server. When the user switches from Wifi to LTE, I get a CLOSED event. How do I either manually reconnect, or configure the original socket to reconnect automatically?

[GeoffreyPlitt]

@darrachequesne Any ideas?

[darrachequesne]

@GeoffreyPlitt doesn't it try to reconnect after a certain delay? do you have any logs?

As usual, which version of engine.io do you use? Does it happen on every mobile device (Android, iOS, ...?) ?

Oddly, it seems to work with Socket.io (I just successfully tested the switch on http://socket.io/demos/chat/)

[GeoffreyPlitt]

We're using engine.io-client=1.6.11 (the latest).

How do I enable logs for your package? I searched your docs and didn't see any mention of "log" or "debug" params to the constructors.

[GeoffreyPlitt]

@darrachequesne How do I give you the logs you need?

[darrachequesne]

Please run your process with debug enabled:

̀> DEBUG=engine.io* npm start

[GeoffreyPlitt]

In my server or my client?

[GeoffreyPlitt]

@darrachequesne If I can catch the error, can you provide a reconnect() method or something?

[GeoffreyPlitt]

@darrachequesne the instructions you gave for logging seem to be for the server, but this is engine.io-client. Is there a way to enable logs in the client?

[darrachequesne]

As documented there, you can enable debug information in the browser with:

localStorage.debug = 'engine.io*'

Regarding the error, one could expect it would reconnect by itself, if it's not it may be a bug or an unhandled case (or both 😄 )

[GeoffreyPlitt]

Unfortunately I'm on React-Native and it does not have localStorage.debug.

Is there a React-Native way to turn on debug logs?

[GeoffreyPlitt]

@darrachequesne I'm on React-Native and I can't get the logs to show. I've tried even modifying the source code, turning some "debug()" statements into console.log(), but it's very hard to figure this out becuase the source code is all compiled with webpack stuff. Is there a separate source codebase I can use that has normal source code?

[darrachequesne]

@GeoffreyPlitt sorry for the delay. You'll have to create a new socket once the first gets closed.
