As part of my renderer process I prompt the user to select a deployment file .dep (zip file) and i would like to pass this to the main process to be sent over SerialPort communication. What is the best way to send this to the main process from renderer? Currently i'm using the preload.js to handle my other communication

on the renderer side i can already read the file, I just was not sure how to send that from renderer to main. or can i just pass the file once i read it on the reactjs side

What do you do with that file?

#

And why do you need that file in main?

#

so from the UI the user selects the file (its a zip) this needs to go to the main to be sent over serial port to an embedded system that i communicate over serial port

#

so the main handles all communication with the serial port

#

it will get chunked out and sent over serial to the device (firmware essentially)

Then send file path

could there be any permission issues potentially?

Permission issue?

#

If you able to read file

#

lets say if the user saves the file in their user directory

#

If application able to write

#
