jsentinel-standalone-persistence

You can add persistent user storage to a standalone Vaadin Flow application by integrating Eclipse-Store as a layer-2 persistence solution. This provides a persistent user directory and a token-based bootstrap process.

The best way to bootstrap the first admin user in a Vaadin standalone app is using a token-based bootstrap process. This approach securely initializes your first administrator credentials during the setup command execution.

Yes, Eclipse-Store persistence requires previous setup with the `jsentinel-standalone` Skill. You must add the `jSentinel-persistence-eclipsestore` dependency to your existing project before applying this persistence layer.

Yes, you can use JDBC or LDAP for user directory persistence instead of Eclipse-Store. The architecture supports a pluggable persistence SPI, allowing you to swap the default Eclipse-Store implementation for JDBC or LDAP.

No, adding this Eclipse-Store persistence will not overwrite your existing Vaadin Main bootstrap. It additively integrates persistence functionality via the `BootstrapExtension` SPI without modifying your current setup.

The pluggable persistence SPI works by allowing you to define custom storage mechanisms for Vaadin Flow user directories. It defaults to Eclipse-Store but enables swapping implementations to JDBC or LDAP seamlessly.
