electron: Uncaught ReferenceError: process is not defined

@msudgh nodeIntegration is turned off by default in 5, so you’ll need to enable it via:

const { BrowserWindow } = require('electron')
let win = new BrowserWindow({
  webPreferences: {
    nodeIntegration: true
  }
})

which we caution against, or add it via preload script.

Note contextIsolation: false now replaces nodeIntegration: true.

I needed to use both, using only contextIsolation: false / nodeIntegration: true doesn’t fix the issue. This affects the quick start guide as only nodeIntegration: true was mentioned there.

update your main.js as follows:

function createWindow () {
  const win = new BrowserWindow({
    width: 600,
    height: 600,
    webPreferences: {
      nodeIntegration: true,
      contextIsolation: false
    }
  })

Note contextIsolation: false now replaces nodeIntegration: true.

Using the quick start (https://www.electronjs.org/docs/tutorial/quick-start), copied exact code, but still doesn’t work 😦

Code:

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

function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true,
    },
  });

  win.loadFile("index.html");
}

app.whenReady().then(createWindow);

app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

app.on("activate", () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow();
  }
});

Error:

Uncaught ReferenceError: process is not defined x 3, because checking Node, Chromium, Electron versions

Where to add this above code?

If i use both of the nodeIntegration:true and constextIsolation:false it shows up a error which is:

If i turn both of them true it still get the error: process is not defined

@codebytere Thanks. it’d be better to update docs. this functionality existed in previous versions.

Wow. Works like a charm. I would request ElectronJS Team to please update the docs and add this, or totally remove the need to use contextIsolation with nodeIntegration

Thanks it worked for me, you don’t that how happy now I am thank you very very much…

@msudgh this information was presented both in release notes and in breaking change documentation leading up to and including the stable release 😃

I did resolve it putting contextIsolation to false.

// 1. import electron objects const { app, BrowserWindow } = require(‘electron’);

// 2. reserve a reference to window object let window;

// 3. wait till application started app.on(‘ready’, () => { // 4. create a new window window = new BrowserWindow({ width: 800, height: 600, webPreferences: { nodeIntegration: true, contextIsolation: false } }); // 5. load window content window.loadFile(‘index.html’); });

Thanks for quick help 😃 this solved the issue in the simple sample 😉
