Scalable, fast and modular micro web framework for Java

∞ do more, more easily

Jooby a scalable, fast and modular micro web framework for Java.

• Simple, effective and easy to learn. Ideal for small but also large scale applications.

• Scalable. Stateless application development.

• Fast. Thanks to the most popular NIO web servers.

• Modular. Make it full-stack via the extensive module eco-system.

• Ready for the modern web, with the awesome and powerful asset module

hello world!

Java:

import org.jooby.Jooby;

public class App extends Jooby {

  {
    get("/", () -> "Hey Jooby!");
  }

  public static void main(final String[] args) {
    run(App::new, args);
  }
}

Kotlin:

import org.jooby.*

fun main(args: Array<String>) {
  run(*args) {
    get {
      "Hello Kotlin"
    }
  }
}

JavaScript:

var app = jooby();

app.get('/', function () 'Hey Jooby!');

killer features

• Multi-language. Write your application in Java, Kotlin or JavaScript

• MVC programming model. Like Spring controllers or Jersey resources
• Multi-server. Including Netty, Jetty and Undertow
• HTTPS
• HTTP/2
• Server-Sent Events
• Web-Socket
• Dependency Injection
• Hot reload for development

requirements

• Install JDK 8+
• Install Maven 3+

quickstart

Just paste this into a terminal (make sure Java 8 and Maven 3.x are installed):

mvn archetype:generate -B -DgroupId=com.mycompany -DartifactId=my-app -Dversion=1.0-SNAPSHOT -DarchetypeArtifactId=jooby-archetype -DarchetypeGroupId=org.jooby -DarchetypeVersion=1.1.2

You might want to edit/change:

• -DgroupId: A Java package's name

• -DartifactId: A project's name in lower case and without spaces

• -Dversion: A project's version, like 1.0-SNAPSHOT or 1.0.0-SNAPSHOT

Let's try it!:

mvn archetype:generate -B -DgroupId=com.mycompany -DartifactId=my-app -Dversion=1.0-SNAPSHOT -DarchetypeArtifactId=jooby-archetype -DarchetypeGroupId=org.jooby -DarchetypeVersion=1.1.2
cd my-app
mvn jooby:run

You should see something similar to this at the end of the output:

INFO  [2015-03-19 21:34:00,365] Hotswap available on: [my-app/public, my-app/conf, my-app/target/classes]

Jooby! is up and running!

getting started

exploring the newly created project

A new directory was created: my-app. Let's see what it looks like:

.
├── public
|   └── (empty)
├── conf
|   ├── application.conf
|   └── logback.xml
└── src
    ├── main
    |   └── java
    |       └── com
    |           └── mycompany
    |               └── App.java
    └── test
        └── java
            └── com
                └── mycompany
                    └── AppTest.java

The public folder contains static content like *.html, *.js, *.css, ..., *.png files.

The conf folder contains *.conf.

The src/main/java folder contains *.java files (of course).

The src/test/java folder contains unit and integration tests.

NOTE: The public and conf folders are part of the classpath.

App.java

import org.jooby.Jooby;

public class App extends Jooby { // 1

  {
    // 2
    get("/", () -> "Hello World!");
  }

  public static void main(final String[] args) {
    run(App::new, args); // 3. start the application.
  }

}

Steps involved are:

1. extend Jooby

2. define some routes

3. call the run method

running

Open a console and type:

mvn jooby:run

The maven plugin will compile the code (if necessary) and start the application.

Of course, you can generate the IDE metadata from Maven or import as a Maven project in your favorite IDE. Afterwards, all you have to do is run the: App.java class. After all, this is a plain Java application with a main method.
