Quick example
from dataclasses import dataclass
from jam import BaseSubject, Jam
@dataclass
class User(BaseSubject):
id: int
email: str
jam = Jam(config="config.toml", subject=User)
user = User(id=1, email="user@example.com")
token = jam.issue(subject=user, via="jwt")
principal = jam.authenticate(token, via="jwt")
user = principal.subject
allowed: bool = jam.authorize(
principal=principal,
permission="post:create"
)
Why Jam?
Jam is a library that provides the most popular AUTH* mechanisms right out of the box.
Authorization
Jam combines permissions granted to one credential with server-side policy rules. This makes it possible to issue two tokens for the same user with different permissions and to restrict those permissions using the current time, resource or request.
principal = jam.authenticate(token, via="jwt")
if jam.authorize(principal, "user:delete"):
...
Framework integrations
Jam provides ready-to-use integrations for the most popular frameworks:
Each integration offers built-in middleware or plugin support for JWT and session-based authentication.
