electron-serve

Static file serving for Electron apps

Normally you would just use win.loadURL('file://…'), but that doesn't work when you're making a single-page web app, which most Electron apps are today, as history.pushState()'ed URLs don't exist on disk. It serves files if they exist, and falls back to index.html if not, which means you can use router modules like react-router, vue-router, etc.

Install

npm install electron-serve

Requires Electron 30 or later.

Usage

import {app, BrowserWindow} from 'electron';
import serve from 'electron-serve';

const loadURL = serve({directory: 'renderer'});

let mainWindow;

(async () => {
	await app.whenReady();

	mainWindow = new BrowserWindow();

	await loadURL(mainWindow);

	// Or optionally with search parameters.
	await loadURL(mainWindow, {id: 4, foo: 'bar'});

	// The above is equivalent to this:
	await mainWindow.loadURL('app://-');
	// The `-` is just the required hostname
})();
