Call function from within node event handler

Question

I'm using icpRenderer to send messages in an electron app from the renderer to the main process. Below is the handler that listens for the messages. I'd like to call another function from within that handler. How can I bind this?

const onMessageReceived = (m: string) => {
  console.log(m);
};

ipcMain.on('my-custom-signal', (event, arg) => {
  this.onMessageReceived(arg);// how can I call this?
});

remove this - unlike languages such as Java this.something() is completely different to something() — VLAZ

this is not the same inside the handler.

You can do this:

let that = this;
const onMessageReceived = (m: string) => {
  console.log(m);
};

ipcMain.on('my-custom-signal', (event, arg) => {
  that.onMessageReceived(arg); // how can I call this?
});
