Hi everyone, I am the release manager of <code>django-modern-rest</code> :) 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: <pre><code>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) </code></pre> 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.

Now, back to the 0.16.0 release! Built during <code>opensource_september</code> 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

<code>extras=</code> for your own typed <code>@modify</code> / <code>@validate</code> 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: <code>@modify(auth=[*auth, other])</code>. AI tooling Agent skills now ship inside the package: uvx library-skills installs the ones matching your version. The new <code>$dmr-upgrade</code> 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.
