`Legacy providers only support notification event.` when using `WebsocketProvider`

[megaturbo]

I'm using the WebsocketProvider and I want to listen to provider events like connect, error, etc...

Right now I'm using this:

import { WebsocketProvider } from "web3x/providers";

const provider = new WebsocketProvider(ws_provider_path);
provider.on("connect", () => console.log("Provider connected."));

But I keep getting this error:

Error: Legacy providers only support notification event.

So why is the WebsocketProvider a legacy provider ? And how can I setup a non-legacy provider to listen to this kind of events ?

The current websocket provider, is the legacy provider wrapped in an adapter. Unfortunately the adapter is provider agnostic so isn't setup to deal with these new events. EIP 1193 remains a moving target (12 days ago ethereum/EIPs#2240).

Regardless, it's would be useful to have providers that meet the spec as it stands. Unfortunately I don't have time to look into this right now. Happy to look over and accept good quality PR's...

Maybe I can help with that, I'll see what I can do when I have time.

For now, do you have any idea how to reconnect the provider after loss of connection ?

[xf00f]

It seems this may be an issue inherited from web3.js.
web3/web3.js#1354

Maybe the provider has been cleaned up and fixed in web3.js and can be migrated in.
Right now not sure what to suggest. I maybe get a chance to look into this in next few weeks.

EIP 1193 remains a moving target

@xf00f looks like EIP-1193 has been finalized: https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1193.md

what's the best way to work on this?
