Fast API Class 3 with PIAIC: Advanced Techniques Uncovered!

Welcome to Fast API Class 3 with PIAIC: Advanced Techniques Uncovered!

In this tutorial, we will cover some advanced techniques in Fast API Class 3 with PIAIC. We will learn how to use Fast API to build powerful APIs and how to leverage its features to create efficient and robust applications.

Setting up Fast API

Before we dive into advanced techniques, we need to set up Fast API on our system. Follow these steps to install Fast API:

pip install fastapi

Defining API Endpoints

Once Fast API is installed, we can define API endpoints using Python functions. Here is an example of defining a basic API endpoint:

from fastapi import FastAPI


        app = FastAPI()

@app.get("/") async def read_root(): return {"message": "Hello World"}

Advanced Techniques

Now that we have our basic API endpoint set up, let’s explore some advanced techniques:

Dependency Injection

Dependency injection allows us to inject dependencies into our API endpoints. Here is an example:

from fastapi import Depends


        async def get_db():

            db = Database()

            return db

@app.get("/") async def read_root(db: Database = Depends(get_db)): return {"message": "Hello World"}

Request Validation

Fast API allows us to validate incoming requests using Pydantic models. Here is an example:

from pydantic import BaseModel


        class Item(BaseModel):

            name: str

            price: float

@app.post("/") async def create_item(item: Item): return {"name": item.name, "price": item.price}

Conclusion

Fast API Class 3 with PIAIC offers a powerful and flexible framework for building APIs. By mastering advanced techniques such as dependency injection and request validation, you can create efficient and robust applications. Happy coding!
