ipc provides an event listeners and event emitter methods or functions for ipc(Inter-process communication) using the process stdin as it's meduim.
I was having one or more issues with any of Nodejs based fs-watcher module I could find,
So I extended my search outside Node and found a package written in Go that addressed all those issues for me but the biggest challenge I was facing then was communicating with the two process (electron (Nodjs) and Go process) I tried using websocket but it didn't work out well until I found a post on how to read/scan the stdin using bufio.NewReader(os.Stdin) which drived the idea from to create this package.
Note: To use this package you must not log/print stuffs with fmt package because fmt writes to process stdout
This package was made with Nodejs as the parent process in mind.
To use this package you will surely need it's Nodejs version ipc-node-go
go get github.com/Akumzy/ipc// main.go binary

text := payload.(string)

ipcIO.OnReceiveAndReply("yoo", func(reply string, payload interface{}) {
log.Println(payload)
ipcIO.Reply(reply, "Sup Node", nil)

// You either start the IPC in it's routine

ipc.onReceiveAnSend('hola', (channel, data) => {
console.log(data)
ipc.send(channel, 'cool thanks')
})
