Summary of Jooby Responses

Jooby is a web framework for building applications in Java, and understanding how to handle responses is crucial for delivering information to clients effectively. Below is a summary of the main points regarding responses in Jooby.

Key Concepts of Jooby Responses

• Responses Overview
  • Responses are what your application sends back to the client after processing a request.
  • They can include various types of content such as HTML, JSON, XML, and plain text.
• Setting Response Status
  • You can specify the HTTP status code for the response.
  • Common status codes include:
    • 200 OK: The request was successful.
    • 404 Not Found: The requested resource could not be found.
    • 500 Internal Server Error: There was a server error.
• Sending Different Content Types
  • Jooby allows you to send different types of responses based on the content type.
  • You can use methods like:
    • send(): Send raw data.
    • json(): Send data in JSON format.
    • html(): Send HTML content.

Examples of Sending Responses

Setting a Custom Status Code

get("/notfound", ctx -> {
    ctx.setStatus(404);  // Sets status to 404
    return ctx.text("Resource not found.");
});

Sending HTML Response

get("/welcome", ctx -> {
    return ctx.html("Welcome to Jooby!");  // Sends an HTML response
});

Sending JSON Response

get("/user", ctx -> {
    User user = new User("John", "Doe");
    return ctx.json(user);  // Sends a JSON response
});

Conclusion

Understanding how to handle responses in Jooby is essential for creating interactive web applications. By utilizing different response types and HTTP status codes, developers can effectively communicate with clients and ensure a better user experience.
