Domain Driven Design guidance for TypeScript/Deno codebases. Apply when writing or modifying code to choose appropriate DDD building blocks (entities, value objects, aggregates, domain services, repositories) and maintain ubiquitous language. Triggers on all code changes to ensure domain model consistency.

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

# Domain Driven Design

Apply these patterns when implementing domain logic in TypeScript/Deno.

## Building Block Selection

Choose the appropriate type based on these criteria:

| Type                    | Identity                 | Mutability              | When to Use                                                                                                                                                             |
| ----------------------- | ------------------------ | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Value Object**        | None (equality by value) | Immutable               | Measurements, descriptions, identifiers, money, dates, addresses                                                                                                        |
| **Entity**              | Has unique ID            | Mutable                 | Things with lifecycle, tracked over time, referenced by ID                                                                                                              |

How to install

The exact contents, by fingerprint
mdr add swamp-club/swamp/ddd@sha256:1a1ffb2ecd69ead6

The line at the top of this page pins the label git:20260916.b07863c, 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.
