JHipster's JDL gives fast, consistent Spring Boot and frontend CRUD, but editing generated files is a trap. Model shape in JDL, keep behavior in custom services outside the generated paths, and accept the regeneration tax.
JHipster's JDL lets you declare entities, relationships, DTOs, and pagination in one file and generate a consistent Spring Boot + Angular/React/Vue stack. A worked User–Authority example shows the output, and the regeneration discipline you'll need.
Learn how to write a JHipster JDL file to define entities and relationships, then generate the full Spring Boot backend and Angular/React frontend with one command.
Learn how to model entities and relationships with JHipster JDL and use incremental generation to preserve custom backend and frontend code.
Treat JHipster's JDL as the canonical domain contract. This blog shows a concrete order-domain example, explains how protected regions preserve custom logic during re-imports, and outlines a safe adoption path for existing projects.
When JHipster’s entity sub‑generator aborts with "Invalid field type" errors, the problem usually lies in a misspelled or unsupported JDL field type. This guide walks through diagnosing the issue, correcting the JDL, and verifying the fix with concrete checks and examples.
Define a paginated entity in JHipster's JDL, import it to generate the full Spring Boot and front-end stack, and verify pagination via the X-Total-Count header — with rollback steps for bad imports.
JHipster's JDL lets you declare entities, relationships, and pagination in one versionable file and regenerate both tiers of a Spring Boot + Angular/React app. Here's a worked example, how to verify it, and the regeneration trade-off.
