engine.io-client instantly permanently attempt to reconnect?

[tgbv]

I'm using the latest socketio versions (4.0)

I have a WS server which is not always online. Is there a way to instantly permanently attempt to reconnect to it in case transport errors/connection refused are encountered?

Default settings don't seem to work that way: if the server is down, socket.io-client gives up reconnect.

Hi! By default, the Socket.IO client will try to reconnect forever. Available options:

• reconnection (defaults to true)
• reconnectionAttempts (defaults to Infinity)
• reconnectionDelay (defaults to 1000)
• reconnectionDelayMax (defaults to 5000)
• randomizationFactor (defaults to 0.5)

The Engine.IO client will not try to reconnect. It behaves like a classic WebSocket client, which means you'll have to manually reconnect. The reconnection is a feature of the Socket.IO client above.

Please note the neither the Engine.IO client nor the Socket.IO client will be able to reach a plain WebSocket server.
