SerialPort: forget() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Dedicated Web Workers.
The SerialPort.forget() method of the SerialPort interface returns a Promise that resolves when access to the serial port is revoked.
Description
A website can clean up permissions to access a serial port it is no longer interested in retaining by calling SerialPort.forget(). Calling this "forgets" the device, resetting any previously-set permissions so the calling site can no longer communicate with the port.
For example, for an educational web application used on a shared computer with many devices, a large number of accumulated user-generated permissions creates a poor user experience.
Syntax
forget()
Parameters
None.
Return value
A Promise that resolves with undefined once the connection is revoked.
