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
Java:
import org.jooby.Jooby;
public class App extends Jooby {
{
get("/", () -> "Hey Jooby!");
}
public static void main(final String[] args) {
run(App::new, args);
}
}
import org.jooby.*
fun main(args: Array<String>) {
run(*args) {
get {
"Hello Kotlin"
}
}
}
var app = jooby();
app.get('/', function () 'Hey Jooby!');
- Support by clicking the ⭐ button on the upper right of this page. ✌️
- Multi-language. Write your application in Java, Kotlin or JavaScript
- Scripting programming model. Like express.js, Sinatra, etc.. but also
- 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
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
or1.0.0-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]
INFO [2015-03-19 21:34:00,368] includes: [**/*.class,**/*.conf,**/*.properties]
INFO [2015-03-19 21:34:00,369] excludes: []

Jooby! is up and running!
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
andconf
folders are part of the classpath.
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:
-
extend Jooby
-
define some routes
-
call the
run
method
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.
