I found some "tricks" to write less code, hence less code to maintain if there are any changes. Also less code with bugs just by changing the inputs.
For example, OpenAPI spec file + OpenAPI generator (https://github.com/OpenAPITools/openapi-generator). Any changes in the OpenAPI spec are reflected in the final code with a build step.
Another example: MapStruct (https://mapstruct.org/) to avoid passing data from Entity classes to DTO and back. Saves looots of boilerplate code.
Which are your tricks?

Most of the time nowadays, I prefer offloading this to an identity provider, using OpenID Connect or soon Federated Credential Management (FedCM), even if that means shipping an identity provider as part of the deliverables (I generally go with Keycloak, with keycloak-config-cli to provision its configuration). I'm obviously biased though as I work in IT services, developping software mainly for intranets/extranets, and companies now increasingly have their own identity providers or at a minimum have that in their roadmap. So YMMV.
Project mention: A multi-protocol, event-native edge/service proxy. New Quickstart! | /r/apachekafka | 2023-07-20Hi gang, we’re building a multi-protocol, event-native edge/service proxy called Zilla. Zilla can abstract Kafka topics for web apps, IoT clients and microservices through user-defined REST, Server-Sent Events (SSE), MQTT, or gRPC APIs.
