type error dialog.showmessageBoxSync is not a function

I just started using electron and fail to use showmessageBoxSync: it returns the error:

type error dialog.showmessageBoxSync is not a function

isn't showmessageBoxSync a member of dialog which is a property of returned object returned by require('electron');? what am I missing? the dialog variable is declared as:

const { app, BrowserWindow, dialog } = require('electron');

this is the full code:

const { app, BrowserWindow, dialog } = require('electron');
const url = require('url');

function newApp() {
        
  dialog.showmessageBoxSync({
    message: 'hello world'
  });
  
  win = new BrowserWindow();
  win.loadURL(
    url.format({
      pathname: "index.html",
      slashes: true
    })
  );
  
  win.on('closed', () => {
      win = null;
  });
}

app.on("ready", newApp);
Solution

  • The method is dialog.showMessageBoxSync, with a capital M.
