Electron Create-React-App TypeScript

This project was bootstrapped with Create React App and TypeScript.

How to make this boilerplate

You can also just clone this repository. But if you just clone and use this repository, may be legacy project. So I recommend you following this description.

At First, Bootstrap Project using Create React App.

$ npx create-react-app <YOUR-PROJECT-NAME> --typescript
$ cd <YOUR-PROJECT-NAME>

Install Electron

$ yarn add -D electron

Create electron-starter.js in Root Directory

Note: Don't use .ts extension. YOU MUST USE .js EXTENSION.

// Modules to control application life and create native browser window
const { app, BrowserWindow } = require("electron");
const url = require("url");
const path = require("path");

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

function createWindow() {
  // Create the browser window.
  mainWindow = new BrowserWindow({ width: 800, height: 600 });

  // and load the index.html of the app.
  const startUrl =
    process.env.ELECTRON_START_URL ||
    url.format({
      pathname: path.join(__dirname, "/../build/index.html"),
      protocol: "file:",
      slashes: true
    });
  mainWindow.loadURL(startUrl);

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()

  // Emitted when the window is closed.
  mainWindow.on("closed", function() {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null;
  });
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on("ready", createWindow);

// Quit when all windows are closed.
app.on("window-all-closed", function() {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== "darwin") {
    app.quit();
  }
});

app.on("activate", function() {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (mainWindow === null) {
    createWindow();
  }
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

Also Create electron-wait-react.js in Root Directory.

Note: Don't use .ts extension. YOU MUST USE .js EXTENSION.

const net = require("net");
const port = process.env.PORT ? process.env.PORT - 100 : 3000;

process.env.ELECTRON_START_URL = `http://localhost:${port}`;

const client = new net.Socket();

let startedElectron = false;
const tryConnection = () =>
  client.connect(
    { port: port },
    () => {
      client.end();
      if (!startedElectron) {
        console.log("starting electron");
        startedElectron = true;
        const exec = require("child_process").exec;
        exec("npm run electron");
      }
    }
  );

tryConnection();

client.on("error", (error) => {
  setTimeout(tryConnection, 1000);
});

Install foreman and cross-env

$ yarn add -D foreman cross-env

Edit package.json

...
"main": "./electron-starter.js",
"scripts": {
  "start": "cross-env BROWSER=none nf start -p 3000",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject",
  "electron": "electron .",
  "electron-start": "node ./electron-wait-react",
  "react-start": "react-scripts start"
},

Create Procfile in Root Directory.

react: npm run react-start
electron: npm run electron-start

Run

$ yarn start
