The Rise of Web-Based Applications
In recent years, the web has become an increasingly popular platform for developing modern applications. With the rise of single-page applications (SPAs) and progressive web apps (PWAs), developers can now create rich, interactive experiences that rival native mobile apps. However, this shift also comes with its own set of challenges.
Performance Overhead
Web-based applications often rely on JavaScript engines like V8 or SpiderMonkey to execute code. While these engines have made tremendous strides in recent years, they still introduce performance overhead compared to native code. For example, a simple JavaScript operation might require tens or even hundreds of cycles to execute, whereas the equivalent operation would be a single instruction on a CPU.
Security Concerns
Web-based applications are also vulnerable to security threats like cross-site scripting (XSS) and cross-site request forgery (CSRF). While modern web frameworks and libraries have made significant strides in mitigating these risks, they're still present. In contrast, native desktop applications can benefit from the same level of security isolation provided by operating system-level protections.

Code Snippet: Building a Tauri App
Here's a simple example of building a Tauri app using Rust:
use tauri::{self, AppHandle, Context, Window};
#[tauri::command]
async fn greet(name: String) -> String {
format!("Hello, {}!", name)
}
#[tauri::main]
async fn main() {
let app_handle = tauri::AppHandle::new().unwrap();
let ctx = Context::new(app_handle);
let window = Window::new(ctx).unwrap();
window.insert_event_handler("greet", |event| async { match event.data::<String>() {
Some(name) => {
println!("{}", greet(name));
}
None => {}
}});
tauri::invoke_handler(&ctx, move |req| {
match req.id {
"greet" => Ok("Hello!".into()),
_ => Err(tauri::Error::UnknownRequest),
}
});
}
This example creates a simple Tauri app with a greet command that prints a personalized message to the console.
As we've explored in previous chapters, building cross-platform desktop applications using web technologies can be a challenging task. Two popular frameworks that have gained significant attention in recent years are Tauri and React Native. In this chapter, we'll delve into the details of both frameworks, exploring their strengths, weaknesses, and comparing them side by side.
Tauri: A Modern Approach
Tauri is an open-source framework developed to provide a more modern and efficient way of building desktop applications using web technologies. At its core, Tauri leverages WebAssembly (WASM) and native APIs to enable seamless interactions between the web and native code.
To get started with Tauri, you'll need to create a new project using the tauri init command. This will generate a basic directory structure for your
app, including the main entry point (src/main.rs) and the necessary dependencies.
Here's an example of how to build a simple Tauri app:
use tauri::{self, AppHandle, Context, Window};
#[tauri::command]
async fn greet(name: String) -> String {
format!("Hello, {}!", name)
}
#[tauri::main]
async fn main() {
let app_handle = tauri::AppHandle::new().unwrap();
let ctx = Context::new(app_handle);
let window = Window::new(ctx).unwrap();
// Create a new button
let button = Button::new()
.label("Greet")
.on_press(move |_, _| async {
let name = String::from("John");
let message = greet(name);
println!("{}", message);
ctx.send(message.into());
});
// Add the button to the window
window.add_button(button).unwrap();
}
This code snippet demonstrates a simple Tauri app with a single button. When the button is clicked, it greets the user and prints the result to both the console and the Tauri logs.
React Native: A Mobile-First Approach
React Native is an open-source framework developed by Facebook to provide a seamless mobile app development experience. With its JavaScript-based syntax, React Native enables developers to build high-performance, visually stunning mobile apps with ease.
To get started with React Native, you'll need to create a new project using the npx react-native init command. This will generate a basic directory
structure for your app, including the main entry point (App.js) and the necessary dependencies.
Here's an example of how to build a simple React Native app:
import React from "react";
import { View, Text, Button } from "react-native";
function App() {
const handleGreet = async (name) => {
console.log(`Hello, ${name}!`);
};
return (
<View>
<Text>Hello World!</Text>
<Button title="Greet" onPress={() => handleGreet("John")} />
</View>
);
}
export default App;
This code snippet demonstrates a simple React Native app with a single button. When the button is clicked, it greets the user and prints the result to both the console and the React Native logs.
Comparison of Tauri and React Native

In conclusion, both Tauri and React Native offer powerful tools for building cross-platform desktop applications. While Tauri provides a more modern and efficient way of building apps using web technologies, React Native offers a mobile-first development approach that makes it easier to build high-performance mobile apps quickly.
When deciding between the two frameworks, consider the following factors:
One of the significant advantages of Tauri over traditional desktop app frameworks like Electron or Qt is its ability to seamlessly integrate Rust code with web-based development tools. This makes it easier to reuse existing Rust code, libraries, and frameworks in your Tauri project.
Tauri provides a plugin architecture that allows developers to write extensions in languages like Swift and Java, which can be easily integrated into their Rust codebase. These plugins provide a way to access native APIs, interact with the operating system, and leverage existing libraries without having to rewrite them from scratch.
For example, you can use the Tauri Swift plugin to create a Swift extension for your Rust application. This allows you to call Rust functions from Swift, share data between languages, and even integrate existing Swift code into your Tauri project.
Similarly, the Tauri Java plugin provides a way to access native APIs, interact with the operating system, and leverage existing Java libraries in your Rust application. This makes it easier to reuse existing Java code in your Tauri project without having to rewrite it from scratch.
In contrast, traditional desktop app frameworks like Electron or Qt often require developers to rewrite their entire codebase in the target language. While this approach can be effective for certain projects, it can also lead to a significant amount of duplicated effort and maintenance overhead.
For instance, if you're building a desktop application with a Rust backend and a web-based frontend using React or Angular, you might want to reuse some of your existing Rust code in the frontend. However, without Tauri's plugin architecture, you'd have to rewrite this code from scratch using JavaScript or TypeScript.
With Tauri's plugin architecture, however, you can easily integrate your existing Rust code into your web-based frontend. You can use Swift or Java plugins to call your Rust functions, share data between languages, and leverage existing libraries without having to rewrite them from scratch.
This approach makes it easier to reuse existing Rust code, reduces the amount of duplicated effort required for development, and saves time that would otherwise be spent on rewriting code from scratch. Overall, Tauri's plugin architecture provides a powerful way to integrate web-based development tools with native languages like Rust, Swift, and Java.
In summary, Tauri's plugin architecture provides a powerful way to integrate web-based development tools with native languages like Rust, Swift, and Java. By reusing existing code, reducing duplicated effort, and saving time, developers can build high-performance desktop applications more quickly and efficiently than ever before.
