What is @ledgerhq/hw-transport?

@ledgerhq/hw-transport is a JavaScript library that provides a set of transport methods to communicate with Ledger hardware wallets. It supports various transport protocols such as USB, WebUSB, and Bluetooth, allowing developers to interact with Ledger devices in a secure and efficient manner.

What are @ledgerhq/hw-transport's main functionalities?

USB Transport

This feature allows you to connect to a Ledger device using USB. The code sample demonstrates how to establish a connection and then close it.

const Transport = require('@ledgerhq/hw-transport-node-hid').default;

async function connectLedger() {
  const transport = await Transport.create();
  console.log('Connected to Ledger via USB');
  await transport.close();
}

connectLedger();

WebUSB Transport

This feature allows you to connect to a Ledger device using WebUSB. The code sample demonstrates how to establish a connection and then close it.

const TransportWebUSB = require('@ledgerhq/hw-transport-webusb').default;

async function connectLedgerWebUSB() {
  const transport = await TransportWebUSB.create();
  console.log('Connected to Ledger via WebUSB');
  await transport.close();
}

connectLedgerWebUSB();

Bluetooth Transport

This feature allows you to connect to a Ledger device using Bluetooth. The code sample demonstrates how to establish a connection and then close it.

const TransportBLE = require('@ledgerhq/hw-transport-ble').default;

async function connectLedgerBLE() {
  const transport = await TransportBLE.create();
  console.log('Connected to Ledger via Bluetooth');
  await transport.close();
}

connectLedgerBLE();
