django-modern-rest@0.16.0 release

Hi everyone, I am the release manager of django-modern-rest :)

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)

Other notable features:

• 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.

• Docs: https://django-modern-rest.readthedocs.io

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.

• 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

• 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

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]).

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.
