FedSearch - Federated network search engine

Powered by type hints — with Pydantic, schema validation and serialization are controlled by type annotations; less to learn, less code to write and integration with your IDE and static analysis tools.

Speed — Pydantic's core validation logic is written in Rust, as a result Pydantic is among the fastest data validation libraries for Python.

JSON Schema — Pydantic models can emit JSON Schema allowing for easy integration with other tools.

Strict and Lax mode — Pydantic can run in either strict=True mode (where data is not converted) or strict=False mode where Pydantic tries to coerce data to the correct type where appropriate.

Dataclasses, TypedDicts and more — Pydantic supports validation of many standard library types including dataclass and TypedDict.

Customisation — Pydantic allows custom validators and serializers to alter how data is processed in many powerful ways.

Ecosystem — around 8,000 packages on PyPI use Pydantic, including massively popular libraries like FastAPI, huggingface/transformers, Django Ninja, SQLModel, and LangChain.

Battle tested — Pydantic is downloaded >70m times/month and is used by all FAANG companies and 20 of the 25 largest companies on NASDAQ — if you're trying to do something with Pydantic, someone else has probably already done it.

I'm working on a #Python project where we want to replace an #WSGI ORM with an #ASGI ORM, but it's tangled into everything and called from all over the business logic. If the ORM would've been decoupled from the objects tossed around in the business logic, it would've been much easier to replace the ORM.

This blog post outlines an example of how this can be done with #Pydantic. I'm also covering decoupling the data store communication via the "Repository pattern".
