• Middleware: Jooby supports middleware for request processing, which can be utilized for tasks like logging, authentication, and error handling.
• Configuration: The framework offers a flexible configuration system, making it easy for developers to manage application settings.

get("/hello", ctx -> ctx.send("Hello World"));

Example of a Simple Jooby Application

Below is a basic example of a Jooby application:

import org.jooby.Jooby;

public class MyApp extends Jooby {
    {
        get("/", ctx -> "Hello from Jooby!");
    }

    public static void main(String[] args) {
        runApp(MyApp.class, args);
    }
}

Explanation of the Example

• get("/", ctx -> "Hello from Jooby!"): This line sets up a route that responds to GET requests at the root URL ("/") with the message "Hello from Jooby!".
• runApp(MyApp.class, args): This method initializes and starts the application.

Conclusion

Jooby stands out as a powerful yet accessible framework for developing web applications in Java. Its modular design, support for multiple languages, and intuitive features like routing and middleware make it an excellent choice for developers of all skill levels aiming to create efficient web applications.
