This package provides a basic client library to communicate with the Flow App running in a Ledger Nano S/X
We recommend using the npmjs package in order to receive updates/fixes.
Notes
Use yarn install
to avoid issues.
Minimal example
This is very simple. First you need to use one of the transport classes provided by Ledger.
import TransportWebUSB from "@ledgerhq/hw-transport-webusb";
transport = await TransportWebUSB.create();
const app = new FlowApp(transport);
the FlowApp
object will provide
const response = await app.getVersion();
if (response.returnCode !== FlowApp.ERROR_CODE.NoError) {
console.log(`Error [${response.returnCode}] ${response.errorMessage}`);
} else {
console.log(response);
}
