nw.js

Pros of Electron

• More active development and larger community support
• Better integration with native OS features and APIs
• Extensive documentation and learning resources

Cons of Electron

• Larger application size due to bundled Chromium
• Higher memory usage compared to NW.js
• Slightly steeper learning curve for beginners

Code Comparison

NW.js:

nw.Window.open('index.html', {}, function(win) {
  win.maximize();
});

Electron:

const { BrowserWindow } = require('electron');
let win = new BrowserWindow({ width: 800, height: 600 });
win.loadFile('index.html');
win.maximize();

Both frameworks allow developers to create desktop applications using web technologies. NW.js provides a more straightforward approach for packaging web apps, while Electron offers greater flexibility and control over the application lifecycle.

Electron has gained more popularity in recent years, with notable applications like Visual Studio Code and Atom being built on it. However, NW.js remains a viable option, especially for simpler projects or those requiring a smaller footprint.

Ultimately, the choice between the two depends on specific project requirements, development team expertise, and desired application features.

Pros of Tauri

• Smaller application size due to using native OS webviews
• Better security with a Rust-based backend
• More modern tech stack (Rust, WebView2) compared to NW.js (Node.js, Chromium)

Cons of Tauri

• Less mature ecosystem and community compared to NW.js
• Limited access to native APIs compared to NW.js's full Node.js integration
• Steeper learning curve for developers not familiar with Rust

Code Comparison

NW.js:

const gui = require('nw.gui');
const win = gui.Window.get();
win.maximize();

Tauri:

#[tauri::command]
fn maximize_window(window: tauri::Window) {
    window.maximize().unwrap();
}

The code snippets demonstrate window manipulation in both frameworks. NW.js uses JavaScript with Node.js integration, while Tauri uses Rust for backend operations and exposes commands to the frontend.

Tauri's approach offers better performance and security but requires more setup. NW.js provides easier access to Node.js APIs but results in larger application sizes.

Both frameworks allow developers to create desktop applications using web technologies, but they differ in their underlying architecture and design philosophy. The choice between them depends on specific project requirements, team expertise, and performance considerations.

Pros of Neutralinojs

• Lightweight: Smaller application size and lower memory footprint
• Cross-platform: Supports Windows, macOS, and Linux with a single codebase
• Native API access: Provides direct access to system-level features

Cons of Neutralinojs

• Limited ecosystem: Fewer third-party extensions and plugins compared to NW.js
• Less mature: Newer project with potentially fewer resources and community support
• Limited browser features: May lack some advanced web technologies available in NW.js

Code Comparison

NW.js:

const gui = require('nw.gui');
const win = gui.Window.get();
win.maximize();

Neutralinojs:

Neutralino.window.maximize();

Both frameworks allow easy window manipulation, but Neutralinojs offers a more streamlined API. NW.js requires importing the nw.gui module and creating a window object, while Neutralinojs provides direct access to window functions through its global Neutralino object.

Neutralinojs aims for simplicity and lightweight applications, making it suitable for projects where minimal resource usage is crucial. NW.js, being more established, offers a wider range of features and better integration with Node.js, making it ideal for complex applications requiring extensive web technologies and npm packages.

Pros of NodeGUI

• Smaller application size and lower memory usage
• Native look and feel with better performance
• Cross-platform development using Qt framework

Cons of NodeGUI

• Less mature ecosystem and community support
• Limited web technologies integration
• Steeper learning curve for developers familiar with web technologies

Code Comparison

NodeGUI:

const { QMainWindow, QWidget, QLabel, FlexLayout } = require("@nodegui/nodegui");

const win = new QMainWindow();
const centralWidget = new QWidget();
const label = new QLabel();
label.setText("Hello World");

const rootLayout = new FlexLayout();
centralWidget.setLayout(rootLayout);
rootLayout.addWidget(label);
win.setCentralWidget(centralWidget);
win.show();

NW.js:

<!DOCTYPE html>
<html>
  <head>
    <title>NW.js App</title>
  </head>
  <body>
    <h1>Hello World</h1>
    <script>
      console.log(nw.App.manifest);
    </script>
  </body>
</html>

NodeGUI focuses on native UI components using Qt, resulting in a more desktop-like experience and smaller application size. NW.js, on the other hand, leverages web technologies, making it easier for web developers to create desktop applications but at the cost of larger file sizes and potentially higher resource usage. NodeGUI offers better performance and a native look, while NW.js provides a more familiar development environment for web developers and easier integration with web technologies.

Pros of Revery

• Native performance with OCaml and Reason
• Cross-platform UI development with a single codebase
• Lightweight and fast startup times

Cons of Revery

• Smaller community and ecosystem compared to NW.js
• Steeper learning curve for developers unfamiliar with OCaml/Reason
• Limited documentation and resources

Code Comparison

Revery (React-like syntax):

let app = () =>
  <View>
    <Text text="Hello, World!" />
    <Button title="Click me" onClick={() => print_endline("Clicked!")} />
  </View>;

App.start(app);

NW.js (HTML and JavaScript):

<!DOCTYPE html>
<html>
  <body>
    <h1>Hello, World!</h1>
    <button onclick="console.log('Clicked!')">Click me</button>
    <script>
      nw.Window.open('index.html', {}, function(win) {});
    </script>
  </body>
</html>

Key Differences

• Revery uses a React-like component model, while NW.js relies on traditional web technologies
• Revery compiles to native code, offering better performance than NW.js's interpreted JavaScript
• NW.js has a larger ecosystem and more extensive documentation
• Revery provides a more consistent cross-platform look and feel
• NW.js allows direct use of Node.js APIs, while Revery requires bindings for native functionality

Pros of fltk-rs

• Lightweight and fast, with minimal dependencies
• Native look and feel on multiple platforms
• Rust-based, offering memory safety and performance benefits

Cons of fltk-rs

• Limited to desktop applications, unlike NW.js's cross-platform capabilities
• Smaller ecosystem and community compared to NW.js
• Less suitable for web developers transitioning to desktop development

Code Comparison

fltk-rs:

use fltk::{app, button::Button, frame::Frame, prelude::*, window::Window};

fn main() {
    let app = app::App::default();
    let mut wind = Window::new(100, 100, 400, 300, "Hello from rust");
    let mut frame = Frame::new(0, 0, 400, 200, "");
    let mut but = Button::new(160, 210, 80, 40, "Click me!");
    wind.end();
    wind.show();
    but.set_callback(move |_| frame.set_label("Hello World!"));
    app.run().unwrap();
}

NW.js:

const gui = require('nw.gui');
const win = gui.Window.get();

win.on('loaded', function() {
  document.getElementById('myButton').addEventListener('click', function() {
    document.getElementById('myFrame').textContent = 'Hello World!';
  });
});

Both examples create a window with a button that, when clicked, updates text on the screen. fltk-rs uses Rust and FLTK bindings, while NW.js leverages web technologies within a native application context.
