Map entities to API DTOs in API Platform (v5, 4.4, 4.3) with the Symfony Object Mapper (#[Map], stateOptions) for decoupled input/output contracts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Api Platform Dto Resources (Symfony) ## Use when - The `#[ApiResource]` class must be the API contract, decoupled from the Doctrine entity. - Entity and API fields differ in name or format (rename, formatted price, computed value). - Create, update, or list operations need their own input or output shape. - Migrating code that relied on `DataTransformerInterface`, which no longer exists. ## Default workflow 1. Require `symfony/object-mapper` and set `stateOptions: new Options(entityClass: ...)` on the DTO resource. 2. Bind the DTO and the entity with `#[Map(source: ...)]` and `#[Map(target: ...)]`, and use `#[Map(transform: ...)]` for computed fields. 3. For distinct shapes, create input and output classes and wire them with `input:` and `output:` on each operation. 4. When mapping needs real logic, write a custom `ProcessorInterface` that calls `ObjectMapperInterface::map()`. 5. Test each operation: payload in, response shape out. ## Guardrails - The automatic Object Mapper provider and processor only apply when `stateOptions` has an `entityClass` and both the DTO and the entity carry `#[Map]`. …

How to install
mdr add dev-toolings/superpowers-symfony/api-platform-dto-resources@sha256:f405ebb8cc26eacfThe line at the top of this page pins the label git:20261005.9484d25, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
