VisualizaçõesES6 import of electron modules with Vite/Vue fails
I am trying to use electron with latest Vite 2/Vue 3. I have setup two versions of electron's main file so I can test and work with both dev server and the build:
- dev version loading the localhost:3000 (from npm run dev) with loadURL
- another version loading the built version (from npm run build)from the dist folder with loadFile
I have set in the new BrowserWindow options:
webPreferences: {
nodeIntegration: true,
contextIsolation: false,
enableRemoteModule: true,
preload: path.join(app.getAppPath(), 'electron.preload.js')
}
The app starts just fine in Electron in both dev and build version, loads all assets and without any security errors. However, when I try to import any module from 'electron' in my project, in example:
import electron from 'electron';
I get the error:
Uncaught TypeError: path.join is not a function
at node_modules/electron/index.js (index.js:4)
I tried to check path and __dirname, to see if they work in my project:
import * as path from 'path';
console.log(path);
console.log(path.join);
console.log(__dirname);
And these do trace out the following in Electron dev panel:
If I try to import path differntly:
import path from 'path'
console.log(path);
console.log(path.join);
I get the following result:
In any case, path.join is undefined. And now I am pretty much stuck on how to go on.
I can also add that I want to use fs-extra, but this also fails:
import fs from 'fs-extra';
[Edit: added the preload in webPreferences]

I believe Vite transforms things a lot behind the scenes. Thankfully @electron/remote provides an alternate way to fetch things:
electron.js:
const { app, BrowserWindow } = require("electron");
const Remote = require("@electron/remote/main");
Remote.initialize();
// ...
app.on("ready", () => {
mainWindow = new BrowserWindow({
webPreferences: {
nodeIntegration: true,
enableRemoteModule: true,
contextIsolation: false,
},
});
Remote.enable(mainWindow.webContents);
mainWindow.loadFile(path.resolve("./dist", "index.html"));
});
// ...
Component.tsx:
import type { BrowserWindow } from "electron";
const Component: React.FC = () => {
const app = window.require("@electron/remote");
const win: BrowserWindow = app.getCurrentWindow();
// ...
}
Not sure if this is the best solution, but it works for me with Vite + Electron + React.
