WebSerial bindings for serialport module.

1. Install module:

   npm i serialport-bindings-webserial

2. Import a module into your code:

   import { SerialPortStream } from '@serialport/stream';
   import { WebSerialBinding } from 'serialport-bindings-webserial';

1. List available and paired ports:

   let ports = await WebSerialBinding.list();
   console.log(ports);

2. Open any port:

   The browser will show pop-up with all available ports.

   let port = await new SerialPortStream({
       binding: WebSerialBinding,
       path: 'webserial://any',
       baudRate: 115200
   });

3. Open any port with custom options for SerialPort.open:

   The browser will show pop-up with all available ports.

   let webSerialOpenOptions = {
       bufferSize: 4 * 1024 // https://developer.mozilla.org/en-US/docs/Web/API/SerialPort/open#buffersize
   };
   
   let port = await new SerialPortStream({
       binding: WebSerialBinding,
       path: 'webserial://any',
       baudRate: 115200,
       webSerialOpenOptions
   });

4. Open any port with filters:

   The browser will show pop-up with all available ports which fit the requested filter.

   let webSerialRequestOptions = {
       filters: [{ usbVendorId: 0x067B, usbProductId: 0x2303 }]
   };
   
   let port = await new SerialPortStream({
       binding: WebSerialBinding,
       path: 'webserial://any',
       baudRate: 115200,
       webSerialRequestOptions
   });

5. Open with native SerialPort:

   You can open a port using reference to the native SerialPort object.

   let webSerialPort = await navigator.requestPort({});
   
   let port = new SerialPortStream({
       binding: WebSerialBinding,
       path: 'webserial://any',
       baudRate: 115200,
       webSerialPort
   });

6. Open port by virtual path:

   let ports = await WebSerialBinding.list();
   
   let port = new SerialPortStream({
       binding: WebSerialBinding,
       path: ports[0].path, // for example: webserial://usb0
       baudRate: 115200,
   });

You need something like vite-plugin-node-polyfills or node-stdlib-browser for using the serialport module in the browser.
