@emdzej/j2534-webusb

Browser WebUSB transport for @emdzej/j2534-driver. Talks to the Tactrix OpenPort 2.0 directly from Chrome / Edge — no native dependencies. Works in any modern Chromium-based browser that exposes navigator.usb.

Install

npm install @emdzej/j2534-driver @emdzej/j2534-webusb

Use

import { J2534Device } from '@emdzej/j2534-driver';
import { createWebUsbTransport } from '@emdzej/j2534-webusb';

// must be called from a user-gesture handler (button click etc.)
const transport = await createWebUsbTransport();

const dev = new J2534Device(transport);
await dev.open();
// … see @emdzej/j2534-driver

The browser shows its USB device-picker dialog; the user grants access per-origin / per-device.
