Validation

FastHTTP supports validation of requests and responses using Pydantic.

Overview

• Response Validation - Validate API responses
• Request Validation - Validate data before sending
• Error Validation - Handle API errors with Pydantic

Quick Example

from pydantic import BaseModel
from fasthttp import FastHTTP
from fasthttp.response import Response


class User(BaseModel):
    id: int
    name: str
    email: str


app = FastHTTP()


@app.get(
    url="https://jsonplaceholder.typicode.com/users/1",
    response_model=User
)
async def get_user(resp: Response) -> User:
    return resp.json()


app.run()

FastHTTP automatically: 1. Receives JSON response 2. Validates against Pydantic model 3. Returns validated object
