Flask + schema = cazart!
cazart is a small helper for writing schematized JSON endpoints with Flask. It rolls
schema into Flask's route decorator, allowing
for one-shot route and schema specification.
cazart requires Python 3.6 or newer.
pip3 install cazartTo use cazart, just swap your Flask instance out for a Cazart one:
from cazart import Cazart
app = Cazart(__name__)You can access all of Flask's baseline functionality (including non-validated routes)
via app.flask.
Then, use app.route to specify a combination route and schema:
from cazart import Cazart
from schema import Schema, Or
app = Cazart(__name__)
@app.route("/cazart", schema=Schema({"name": Or("alice", "bob", "mary")}))
def cazart(res):
print(f"my verified payload is {res}!")
return ("ok", 200)See the examples for full usage examples, including custom error handling and dispatching to different schemas on a route based on HTTP method.
