Community Edition | URL Shortener

The Community Edition is the product, not a demo. It runs a full URL shortening service on your own infrastructure with no feature timer, no usage ceiling and no telemetry.

What you get

Module	Content
`core`	domain model, DTOs, validation, JSON
`server`	REST admin API and redirect server — JDK `HttpServer`, jSentinel security, EclipseStore persistence
`client`	Java SDK for the REST API
`ui`	Vaadin admin interface

Features. Short links with custom aliases and expiration, the redirect service, click statistics (device, referrer, language, bot detection over a hashed IP), user management with roles and permissions, bulk creation, import and export, and a full REST API with a Java client SDK.

Build it yourself

./mvnw clean verify

The reactor runs the complete test suite, including the end-to-end and security suites — these start a real server in-process rather than mocking it. All persistent test state is written below target/, so mvn clean resets everything.

Extension points

The community edition publishes the seams the Enterprise Edition plugs into. They are ordinary Java SPIs, so your own plug-ins can use them too:

Server — com.svenruppert.urlshortener.api.extension: HandlerContribution with a ServerContext, plus lifecycle hooks for create-time metadata, delete cascades and list filters. Contributed endpoints run behind the standard security pipeline; duplicate paths fail fast at startup.
UI — com.svenruppert.urlshortener.ui.vaadin.extension: FeatureContribution contributes routes, drawer entries, navbar components and sections in the link create form and details dialog. Contributed routes are registered dynamically under the main layout.
