1:n relationships between entities can be implemented productively and flexibly in business web apps made with Hilla and the AutoGrid and AutoForm components.

Uploading and downloading files is easy to implement in web apps based on the Hilla framework in conjunction with Spring.

Since version 2.5 of the Hilla framework, the CrudService<T, ID> interface is available for the AutoCrud component. This allows data to be created, read, updated and deleted in a non-JPA-based database, such as MongoDB.

JVM flags for heap memory come with a few surprises when used for applications running in containers. Thoughtless use can easily allocate too little or too much memory.

Authentication and role-based authorization for Hilla web apps can be easily implemented, for example in conjunction with Keycloak and the Authorization Code Flow of OAuth 2.0.

Since version 2.5 of the Hilla framework, the ListService interface is available for the AutoGrid component. This allows data to be read from a non-JPA-based database, like MongoDB, for example.
