Requiring electron dialog from render process is undefined

electron remote undefined
electron custom dialog
electron require in renderer process
cannot read property 'showopendialog' of undefined
electron save file
electron showopendialog callback
npm electron dialog
electron file browser

I am using electron and am trying to open a file browser when a user clicks on button. From the render process I am trying to include the elctron.dialog package like this.

const dialog = require( 'electron' ).dialog;

console.log( dialog );

However the result from the console log is undefined

I am absolutely sure I am in the rendering process so I am not sure why this is not working. The documentation suggests that this is the correct way of doing things but it appears to not be working.

This is my package.json file

{
  "name": "my-app",
  "version": "0.1.0",
  "main": "./main.js",
  "scripts": {
    "start": "electron ."
  },
  "dependencies": {
    "electron": "^0.4.1"
  }
}

This is my main.js file

    'use strict';

    var app = require( 'app' );
    var BrowserWindow = require( 'browser-window' );
    var ipc = require( 'ipc' );

    var mainWindow = null;

    app.on(
        'ready', function () {
            mainWindow = new BrowserWindow(
                {
                    frame : true,
                    height: 700,
                    width : 500
                }
            );

            mainWindow.loadUrl( 'file://' + __dirname + '/app/index.html' );

            mainWindow.openDevTools();
            mainWindow.on(
                'closed', function () {
                    mainWindow = null;
                }
            );

        }
    );

    ipc.on(
        'close-main-window', function () {
            app.quit();
        }
    );

this is the rendered process file

    // Add your index.js code in this file
    var ipc = require( 'ipc' );

    const dialog = require( 'electron' ).dialog;

    console.log( dialog );

This is the console

Is this incorrect?

On the Renderer process, you must use the Remote module.

const dialog = require('electron').remote.dialog

Electron in the newest version have changed the way of requiring the modules. The modules are encapsulated within the electron Name space.

// for getting the electrons modules here the new method now i'm using 1.7.12 Electron version (i don't know what that will be in the future)
// you require electron first! it's a name space (module)
var electron = require("electron");
var remote = electron.remote; // you get all the subModuls directly as property (cool incapsulation)
//remote = require("remote") ===> will not work!!!!

// for dialog it's the same !! but we now use remote as modul
var dialog = remote.dialog;

Also you can use this syntax, to import several modules with less writing and by gathering them all together:

var {remote, ipcRenderer, someOtherModulFromElectron} = electron;

for example in the main.js (main process) we could write such a call:

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

in place of :

const electron = require('electron')

// Module to control application life.
const app = electron.app

// Module to create native browser window.
const BrowserWindow = electron.BrowserWindow

//modul for bar menu
const Menu = electron.Menu

dialog, If you want to use the dialog object from a renderer process, remember to access it const { dialog } = require('electron').remote console.log(dialog) Returns String[] | undefined , the file paths chosen by the user; if the dialog is cancelled it​  The problem was that I didn't notice the require is not defined at the top of console.. After searching for it, I found Sathiraumesh's answer, and after adding webPreferences: {nodeIntegration: true} to the main.js file:

After a few hours of looking into it someone else pointed out to me that the "new" way (4/15/16) of doing this is the following.

var remote = require('remote');
var dialog = remote.require('dialog');

dialog.showOpenDialog({ 
  properties: [ 'openFile' ] }, function ( filename ) {
    console.log( filename.toString() );
  }
);

You must require remote and then from remote require dialog. It looks like you no longer need to require electron

remote, In Electron, GUI-related modules (such as dialog , menu etc.) In order to use them from the renderer process, the ipc module is necessary to const { BrowserWindow } = require('electron').remote let win = new withLocalCallback​() console.log(withRendererCb, withLocalCb) // [undefined, undefined, undefined​], [2, 3, 4]. All pages (rendering process) should be managed and scheduled by the main process. Renderer process. Each page is a renderer process, so the page created by browserwindow above is running in theRenderer processOn. To make it more intuitive, let’s change the demo file structure.

You can directly grab it out from electron using following syntax:

const electron = require('electron')
const {dialog} = electron;

And then you can call the required dialog methods as below:

dialog.showOpenDialog({ properties: ['openFile'] }, (filename) => {
  console.log(filename.toString());
});

New features of Node.js are usually brought by V8 upgrades, since Electron is using To share data between web pages (the renderer processes) the simplest way is to require('electron').xxx is undefined. In Electron, GUI-related modules (such as dialog, menu etc.) are only available in the main process, not in the renderer process. In order to use them from the renderer process, the ipc module is necessary to send inter-process messages to the main process.

Comments
  • Have you tried the Remote module? const dialog = require('electron').remote.dialog
  • I posted my solution above. Your method appears to work in some other versions but not in mine.
