Requirements

  • A browser implementing Web Serial.
  • HTTPS in production or localhost during development.
  • A user action, such as a button click, before opening the device chooser.
  • Exclusive access to the selected serial port.
import { V5SerialDevice } from "@v5x/serial";

const connectButton = document.querySelector<HTMLButtonElement>("#connect");

connectButton?.addEventListener("click", async () => {
  const device = new V5SerialDevice(navigator.serial);
  const connected = await device.connect();
  console.log({ connected });
});
Keep the device instance so it can be disposed later. Creating one starts its periodic refresh timer.
