Access serial port in web worker

Question

I want to access the serial port navigator.serial.requestPort() in web worker, but I get this error:

Uncaught (in promise) TypeError: navigator.serial.requestPort is not a function

How can I fix this?

Answer 1

You can't call requestPort from a worker, you'll need to call requestPort in the main application code then tell the worker to open the port.

See example here
