Node-serialport: (node:80839) Electron: Loading non context-aware native modules in the renderer process is deprecated

[xenkuo]

Summary of Problem

(node:80839) Electron: Loading non context-aware native modules in the renderer process is deprecated

Will node-serial adapt to be a context-aware native module? As in renderer process communicate to serial port is much more easier than in main process of Electron.
(Please answer all 3)

• What are you trying to do?
  I mode a new cross platform serial port tool named comNG. Thanks for the great lib, it works quite well. The only problem is the above warning message.
• What happens?
  Electron report above warning message.
• What should have happened?
  No this warning message.
  

  Code to Reproduce the Issue

Use serial port lib in renderer process of electron.

const serialport = new SerialPort(path)

// Code

Versions, Operating System and Hardware

Version: 8.0.7
OS: mac, win, linux
Hardware: normal serialport tool

• SerialPort@?
• Node.js v?
• Windows? Linux? Mac?
• Hardware and chipset? (Prolific/FTDI/Other)

Yes, it's something we'd like to do. It's something we need help doing.

In my case I'm getting an error instead of a warning:

[reconbot]

nope, nobody has helped yet

[proto6]

also getting an error in latest Electron 9.0.4 when serialport is imported into Renderprocess - current workaround is to set app.allowRendererProcessReuse = false; in main process, but as Electron has announced this flag will be fully deprecated in the near future.

Any further update?

Waiting for an update, my Electron build on Raspberry Pi gives the same error...

[EngJay]

@reconbot I'd consider contributing on this but I'll have to get up-to-speed on the code base and what needs to be done. I've read-up a bit on the issue in the discussions in the electron repo but haven't had a chance to go further than that.

[arturbp]

Getting the same here when try to use 'usb' lib...

[illysky]

Waiting here too!
