Django-modern-rest 0.16.0 release
django-modern-rest 0.16.0 is out!
Is this your first time that you hear about this project? django-modern-rest is a fully typed / fast / flexible / async-ready framework to create REST APIs for Django. It supports Pydantic, msgspec, attrs and many other models.
Here's how the code looks like:
import uuid
import pydantic
from dmr import Body, Controller
from dmr.plugins.pydantic import PydanticFastSerializer
class UserCreateModel(pydantic.BaseModel):
email: str
class UserModel(UserCreateModel):
uid: uuid.UUID
class UserController(Controller[PydanticFastSerializer]):
def post(self, parsed_body: Body[UserCreateModel]) -> UserModel:
return UserModel(uid=uuid.uuid4(), email=parsed_body.email)
- Builtin auth with sessions / JWT headers and cookies
- Validation of requests and responses according to the OpenAPI spec in debug mode, the spec is the source of truth
- Builtin content negotiation, supporting conditional request and response models for different content types
- Flexible error handling
- Optional error model negotiation and complete customization
- Streaming of SSE and JsonLines
- Code reuse is the first-class citizen, create your own typed abstractions and use them with ease and safety
- Advanced testing strategies, including OpenAPI coverage testing and property based tests with the help of schemathesis
- AI as the first-class feature: skills, contexts, mcps, etc. But, no slop inside.

Now, back to the 0.16.0 release!
Built during `opensource_september` community event with 32 contributors and 144 commits. This is our fastest release ever.
## Performance
- PydanticFastSerializer: deserialize x2.2, serialize x1.33 faster
- New BodyMsgspec component: decodes request bytes straight into a msgspec.Struct, x1.6 faster than Body
- msgspec request context validation x2 faster
- Content negotiation is memoized per header: up to x65 faster for browser-style Accept headers
- msgspec 0.22.0, cheaper checks, cookies, headers, and responses
## Features
- Default values for components: Body[Model | None] = None just works
- concrete_views for JWT, token, and session auth: a login route in one line of urls.py, zero view code
- Cursor (keyset) pagination with sync and async APIs
- `extras=` for your own typed `@modify` / `@validate` parameters
- PEP 696 TypeVar defaults for reusable controllers
- First-class CSRF: proper 403 specs and REST error responses
- external_re_path and nested external_path
- Error handlers can re-raise a new error for the next layer
- OpenAPI: x-extensions on every object, security for gateways and mTLS, OpenAPI 3.2 fields, controller-level tags/deprecated/servers, deterministic schema output
## One rule for all config
Settings are no longer merged across levels. Endpoint overrides controller, controller overrides settings. Explicit [] or None disables, EMPTY falls through. Merge explicitly when you want it: `@modify(auth=[*auth, other])`.
## AI tooling
Agent skills now ship inside the package: uvx library-skills installs the ones matching your version. The new `$dmr-upgrade` skill carries the migration prompts, so ask your coding agent to upgrade you from 0.15.0. Every docs page is also served as Markdown.
