watchAvailableSolanaConnectors()

watchAvailableSolanaConnectors(onChange): () => void

Defined in: utils/watchAvailableSolanaConnectors.ts:22 

Calls onChange whenever a Wallet Standard wallet registers or unregisters, so that a list built with getAvailableSolanaConnectors can be read again. Wallets can register after the page loads (an extension that injects its script late, a wallet enabled while the page is open), and that list does not update by itself.

Subscribes to the register and unregister events of getWallets() from @wallet-standard/app. The first getWallets() call of the page also dispatches the wallet-standard:app-ready event to the wallets and listens for their wallet-standard:register-wallet events, as getAvailableSolanaConnectors does. It does not filter: onChange also runs for wallets that getAvailableSolanaConnectors leaves out. It does not follow the change events of the wallets themselves, so a wallet that registers without a required feature and adds it later does not call onChange. On the server (no window), where no wallet registers, it subscribes to nothing.

Each call subscribes on its own: the same onChange passed twice runs twice per event, and each returned function stops only its own subscription.

Parameters

onChange

() => void

Called with no arguments after each registration or unregistration. The registry catches an error it throws and logs it with console.error, so it does not reach the wallet that registered.

Returns

Stops the subscription. The registry keeps its listeners in memory until it is called.

() => void
