WebPush4J

Refactored and improved version of WebPush

• Switch from Gradle to Maven
• Updated dependencies
• OkHttp instead of httpcomponents
• Reduced code, cleanups and refactorings
• Fluent API
• Requires Java 21

Usage

1. Add the WebPush4J dependency to your pom.xml:

<dependency>
    <groupId>de.svenkubiak</groupId>
    <artifactId>webpush4j</artifactId>
    <version>x.x.x</version>
</dependency>

2. Create a Subscriber or load from e.g. database

String json = ... //Json from initial subscription
Subscriber subscriber = Subscriber.from(json);

3. Create a notification

Notification notification = Notification.create()
    .withTitle("Hello!!")
    .withBody("New Message from your favorite Server.");

4. Send the notification to the subscriber

try {
    WebPush.crerate()
		.withPublicKey("PUBLIC KEY") //Vapid public key
 		.withPrivateKey("PRIVATE KEY") //Vapid private key
  		.withSubject("SUBJECT");
        	.withSubscriber(subscriber)
        	.withNotification(notification)
        	.send();
} catch (WebPushException e) {
    e.printStackTrace();
}
