The Role of Electron

To bridge the gap between web technologies and desktop environments, frameworks like Electron come into play. Electron allows developers to create desktop applications using web technologies like HTML, CSS, and JavaScript. It essentially wraps a web application in a native container, providing access to native APIs and enabling the application to run on Windows, macOS, and Linux.

Integrating Next.js with Electron

While Next.js is not designed to create desktop applications out-of-the-box, it can be integrated with Electron to leverage its capabilities. Here's how:

Setting Up the Environment

First, you need to set up both Next.js and Electron in your project. Start by creating a Next.js application:

npx create-next-app my-next-app
cd my-next-app

Then, install Electron:

npm install electron --save-dev

Creating the Electron Main Process

Create a new file, main.js, in the root of your project to define the main process of the Electron application:

const { app, BrowserWindow } = require("electron");
const path = require("path");
const isDev = require("electron-is-dev");

let mainWindow;

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

  mainWindow.loadURL(
    isDev
      ? "http://localhost:3000"
      : `file://${path.join(__dirname, "out/index.html")}`,
  );

  mainWindow.on("closed", () => (mainWindow = null));
}

app.on("ready", createWindow);

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

app.on("activate", () => {
  if (mainWindow === null) {
    createWindow();
  }
});

This script initializes an Electron window and loads your Next.js application, either from a local server during development or from a static build in production.

Running the Development Environment

To run your application in development mode, you need to start both the Next.js development server and the Electron application. Modify the package.json scripts as follows:

"scripts": {
  "dev": "next dev",
  "electron-dev": "concurrently \"npm run dev\" \"wait-on http://localhost:3000 && electron .\""
}

Then, run the development environment with:

npm run electron-dev

Building the Production Application

For production, build your Next.js application and package it with Electron:

npm run build
next export

Modify the Electron main.js to load the static files from the Next.js build directory. Finally, use a tool like electron-builder to package your application for different operating systems.
