This is a simple wrapper for the existing adapter-node SvelteKit adapter, with the exception that this package exports custom functions to handle the integration and running of the polka server and handler that are built from the node adapter.

This adapter requires additional files and configuration to work properly. An example of a working electron app can be found in the examples directory here.

This package uses electron-builder to build the electron app, and electron-is-dev to determine if the app is running in development mode.

Below is an example of how to use this adapter in your main electron file.

import { app, BrowserWindow } from 'electron';
import { start, load } from 'adapter-electron/functions';
import isDev from 'electron-is-dev';
import log from 'electron-log/main';
import nodePath from 'node:path';


const port = await start();

async function createWindow() {
	// Create the browser window

	const mainWindow = new BrowserWindow({
		width: 800,
		height: 600,
		webPreferences: {
			preload: nodePath.join(__dirname, '../preload/index.mjs')
		}
	});

	// Load the local URL for development or the local
	// html file for production
	load(mainWindow, port);

	if (isDev) mainWindow.webContents.openDevTools();
}

If you are having issues with this adapter running or building properly, it's most likely related to the ORIGIN configured.
I implented a sort of SHIM that will set the value at runtime to the correct value for the local electron desktop environment.

This implementation is fully functional with the caveat that this PR be merged.
I have patched the package locally in node modules and validated everything builds perfectly.
