reconnecting event gone?!
Problem
Why was the 'reconnecting' event removed? We used it to better control the reconnection timeouts and behavior. Also we now have no visibility into wether SocketIO is trying to reconnect or not. Please put it back.

1 Fix
Reintroduce 'reconnecting' Event in Socket.IO
The 'reconnecting' event was removed in recent versions of Socket.IO to simplify the event model and reduce complexity in event handling. This change has led to a lack of visibility into the reconnection process, which is critical for applications that require fine-tuned control over reconnection behavior and timeouts.
Awaiting Verification
Be the first to verify this fix
- 1
Fork Socket.IO Repository
Create a fork of the Socket.IO repository on GitHub to implement the necessary changes to reintroduce the 'reconnecting' event.
- 2
Modify Socket.IO Client Code
In the client-side Socket.IO code, locate the section responsible for handling reconnections. Reintroduce the 'reconnecting' event by adding an event emitter that triggers when a reconnection attempt starts.
javascriptsocket.on('reconnecting', (attemptNumber) => { console.log(`Reconnecting attempt #${attemptNumber}`); }); - 3
Update Documentation
Ensure that the documentation reflects the reintroduced 'reconnecting' event, including its usage and parameters. This will help other developers understand how to utilize this event effectively.
- 4
Test the Implementation
Run tests to ensure that the 'reconnecting' event is firing correctly during reconnection attempts. Verify that the application behaves as expected when the connection is lost and restored.
javascriptdescribe('Socket.IO Reconnecting Event', () => { it('should emit reconnecting event', () => { const socket = io(); socket.on('reconnecting', (attemptNumber) => { expect(attemptNumber).to.be.a('number'); }); socket.disconnect(); }); }); - 5
Submit Pull Request
Once the changes are verified, submit a pull request to the original Socket.IO repository to propose the reintroduction of the 'reconnecting' event for consideration by the maintainers.
Validation
Confirm that the 'reconnecting' event is emitted during reconnection attempts by observing console logs or using unit tests. Ensure that the application can handle the event appropriately and that the reconnection behavior meets the desired specifications.
