Architecture Diagram (Our 3 Layers) Recalling our previous post about layered architecture: ```mermaid graph BT subgraph Data_Layer DB[(Database)] end subgraph Business_Layer Logic[Domain Logic] end subgraph Presentation_Layer UI[User Interface] end UI --> Logic Logic --> DB ``` ----- ## How does it work? We are using **Mermaid.js**, a JavaScript-based tool that renders simple text definitions into Scalable Vector Graphics (SVG). This makes the blog load faster and ensures the information is accessible to screen readers. We hope this new tool makes your software development journey much more visual and straightforward. Try it out now by downloading any of the diagrams above\! **Sources to learn more about Mermaid:** * **Mermaid Live Editor:** [mermaid.live](https://mermaid.live/) * **Official Documentation:** [mermaid-js.github.io](https://www.google.com/search?q=https://mermaid-js.github.io/mermaid/) ----- *Visualize the code, master the system.

Eclipse Vert.x (The Reactive Beast) Vert.x is not a traditional framework; it is a *toolkit* for building reactive applications on the JVM. It uses an "Event Loop" (just like Node.js), meaning it can handle tens of thousands of concurrent connections using very few CPU threads. * **Best for:** Real-time applications (chats, live financial dashboards with WebSockets), video streaming, and systems with extremely high network loads. * **Endpoint Example:** ```java import io.vertx.core.Vertx; public class App { public static void main(String[] args) { Vertx vertx = Vertx.vertx(); vertx.createHttpServer().requestHandler(req -> { if (req.uri().equals("/api/greeting")) { req.response().end("Hello from Vert.x!"); } }).listen(8080); } } ``` ### 6. Dropwizard Dropwizard was one of the pioneers in packaging a Java application with an embedded web server (Jetty) into a single `.jar` file. It is highly "opinionated", meaning it forces you to use the libraries they consider the best (Jersey for REST, Jackson for JSON, Metrics for monitoring). * **Best for:** Production-grade RESTful services where stability is paramount and you need operational metrics from minute zero. * **Endpoint Example:** ```java @Path("/api/greeting") @Produces(MediaType.APPLICATION_JSON) public class HelloResource { @GET public String greet() { return "{\"message\": \"Hello from Dropwizard!\"}"; } } ``` ### 7. Helidon (Oracle’s Contender) Helidon is a collection of libraries for writing microservices, backed by Oracle. It comes in two flavors: *Helidon MP* (for those who like classic enterprise standards) and *Helidon SE* (its reactive, ultra-lightweight version that doesn't use annotations). * **Best for:** Migrating legacy applications to microservices within the Oracle ecosystem or building high-performance reactive APIs. * **Endpoint Example (Helidon SE):** ```java import io.helidon.webserver.Routing; import io.helidon.webserver.WebServer; public class App { public static void main(String[] args) { Routing routing = Routing.builder() .get("/api/greeting", (req, res) -> res.send("Hello from Helidon!")) .build(); WebServer.create(routing).start(); } } ``` ### 8. Spark Java (The Minimalist) *Note: Not to be confused with Apache Spark (which is for Big Data).* Spark Java is another micro-framework inspired by Sinatra (Ruby). It was created to make building web applications in Java as easy as possible with minimal effort and zero XML configurations. * **Best for:** Students, quick proofs of concept (PoCs), and extremely small services that don't require a complex architecture. * **Endpoint Example:** ```java import static spark.Spark.*; public class App { public static void main(String[] args) { get("/api/greeting", (req, res) -> "Hello from Spark Java!"); } } ``` ### 9. Play Framework Play was designed to solve the performance deficiencies of traditional web frameworks. It is built on Akka (a very powerful concurrency tool) and is "Stateless," making it perfect for horizontal scaling. * **Best for:** Full-Stack web applications (with integrated frontend), high-traffic portals, and architectures requiring heavy asynchronous processing. * **Endpoint Example:** ```java import play.mvc.*; public class HelloController extends Controller { public Result greet() { return ok("Hello from Play Framework!"); } } ``` ### 10. Jersey (The JAX-RS Standard) Jersey is not a full framework, but a library that implements the official Java specification for RESTful APIs (JAX-RS). Many tools (like Dropwizard or Helidon) use it under the hood. * **Best for:** Developers who need to strictly adhere to Jakarta EE (formerly Java EE) standards and traditional corporate environments. * **Endpoint Example:** ```java @Path("/api") public class HelloResource { @GET @Path("/greeting") @Produces(MediaType.TEXT_PLAIN) public String greet() { return "Hello from Jersey!"; } } ``` --- ### Conclusion Learning to code shouldn't be about suffering through the configuration of obsolete tools; it's about choosing the right piece of technology to solve a specific problem. If you need the industry heavyweight, go for **Spring Boot**. If you want to modernize and save money on cloud hosting, learn **Quarkus** or **Micronaut**. And if you just want to test an idea this weekend without stressing out, give **Javalin** a try. Which of these have you used in your projects, or which one are you forced to use at university?
