Build RESTful API with FastAPI (with code snippets)

In this thread, we'll learn how to create a REST API for TODO App in Python using FastAPI. @FastAPI

A Thread 🧵👇
1. Install FastAPI

The first step is to install FastAPI using pip
2. Create Hello World in @FastAPI

create main.py file with the below code.
3. Run the live server

Use the below command to start the live server.

the server will be running at localhost:8000 by default
4. Check out Interactive API docs

Go to http://127.0.0.1:8000/docs and you will see Interactive API documentation provided by Swagger UI
5. Add Your First Model in FastAPI

Now the real fun starts 🤩

In this example, I have RedisJSON database. You can use the database of your choice.

Please note that redis_om module needs to be installed for connecting with RedisJSON.
6. Implement GET method:

List all the Tasks from the database
7. Implement POST method: Adding Tasks

Add this code to your main .py
8. Implement PUT method: Update Task

Add the below code to main. py to include PUT method
9. Implement the DELETE method: Delete Task

Add the below code to main. py to include the DELETE method
10. All together:

After putting all the code together, we should be able to see the interactive API docs at localhost:8000/docs.
That's a wrap!

I hope you enjoyed this @FastAPI thread
