Mizan's protocol layers (origin Redis cache, Edge Worker) handle caching
autonomously. The origin emits Cache-Control: no-store on ALL responses —
browsers and non-Mizan intermediaries must not cache. The Edge Worker
controls CDN caching via cf object, independent of origin headers.
Also fixes:
- TS localeCompare → byte-order sort (localeCompare is locale-sensitive,
would produce different HMAC keys for non-ASCII params vs Python)
- Python cache_purge: empty {} params no longer treated as falsy
(was inconsistent with JS where {} is truthy)

mizan (Python)
Django server functions framework. See the monorepo root for full documentation.
Install
uv add "mizan[channels,allauth] @ git+https://git.impactsoundworks.com/isw/mizan.git#subdirectory=django"
Setup
# settings.py
INSTALLED_APPS = ["mizan", ...]
# urls.py
path("api/mizan/", include("mizan.urls"))
# asgi.py (optional, for WebSocket)
from mizan import wrap_asgi
application = wrap_asgi(get_asgi_application())
Define Functions
from mizan.client import client
from mizan.setup.registry import register
from pydantic import BaseModel
class Output(BaseModel):
message: str
@client
def echo(request, text: str) -> Output:
return Output(message=text)
register(echo, "echo")
Register in apps.py:
def ready(self):
import myapp.mizan_clients
Auth
@client(auth=True) # requires authentication
@client(auth='staff') # requires is_staff
@client(auth='superuser') # requires is_superuser
@client(auth=my_callable) # custom check
Contexts
@client(context='global') # fetched once, SSR-hydrated, becomes useCurrentUser()
@client(context='local') # fetched with params, becomes <GreetProvider>
Forms
from mizan.forms import mizanFormMixin, mizanFormMeta
class ContactForm(mizanFormMixin, forms.Form):
mizan = mizanFormMeta(name="contact", title="Contact Us")
name = forms.CharField()
email = forms.EmailField()
def on_submit_success(self, request):
return {"sent": True}
Auto-registers contact.schema, contact.validate, contact.submit. Generates useContactForm() with Zod validation.
Channels
from mizan.channels import ReactChannel
class ChatChannel(ReactChannel):
class Params(BaseModel):
room: str
class DjangoMessage(BaseModel):
text: str
def authorize(self, params):
return self.user.is_authenticated
def group(self, params):
return f"chat_{params.room}"
Generates useChatChannel({ room }).
