NWC-only mode?

[futurepaul]

I'd like to use this button for getting an NWC string but don't want my app to have to know all about webLN as well. is there a way to put this into "nwc only" mode so it gets NWC strings from alby and mutiny but doesn't do any other protocols?

Hi @futurepaul, thanks for reporting.

Similar to #11 - I will close it for now

@futurepaul this should be possible now with passing the filters="nwc" attribute to the button or modal. (in version 2.3.1)

@futurepaul we currently don't have a public interface for getting the NWC string because Bitcoin Connect only exposes the WebLN interface. You can get it from the webln object that is added to the window once the connection is connected, but I'll keep this open until we find a better way to expose that (and how NWC in general fits in with Bitcoin Connect which was originally focused on WebLN)

Currently the NWC string is available at window.webln.nostrWalletConnectUrl after connecting but this is not publicly exposed / part of the webln spec. This is a problem is shown in the ZapPlanner PR to add Bitcoin Connect - we need a nice way to expose additional capabilities outside of webln that is not biased to just NWC but also supports other connector capabilities CC @bumi @reneaaron

This will be solved in the next major version of Bitcoin Connect (#140):

import { WebLNProviders, requestProvider } from "@getalby/bitcoin-connect";

const provider = await requestProvider();

if (provider instanceof WebLNProviders.NostrWebLNProvider) {
  // do something with provider.nostrWalletConnectUrl;
}
