FastAPI - Introduction

In this article, I will introduce you to the most trending Python framework which can primarily be used for building robust APIs.

The key features of FastAPI are:

Fast - FastAPIs performance exceeds Nodejs and Go, as it runs under the uvicorn server which is one of the most secured available servers as of now
Easy to Code - With FastAPI, creating an API is as easy and joyful as unboxing your new iPhone. An API can be written in under two minutes with FastAPI.
Automated Docs - With FastAPI, the developer need not spent time writing documentation of the APIs that were built. Because swagger docs are automatically created in detail as you keep writing APIs.
Robust - FastAPI can guarantee you a production-ready code from day one.
Short and Sweet - The minimal the code requirement, the fewer the bugs are. APIs can be strictly typed using pydantic types, which helps the creation of interactive documentation.
Standard - The API creation here follows the OpenAPI standards to be universally stable and compatible.

Steps to start with FastAPI

Let's install Python first so that FastAPI works along with it.
```
  sudo apt update
  sudo apt install python3.8
```
Install the package manager of python, python-pip which will get us all the required libraries for our FastAPI setup
```
  sudo apt-get install python3-pip python-dev
```
Now install FastAPI and all dependencies with a one-liner. This also includes the uvicorn server
```
  pip install "fastapi[all]"
```
Now we are ready to use the FastAPI framework and build some lightning-fast APIs. We'll discuss how to build a standard folder structure and a set of backend APIs related to an interesting topic with FastAPI. Stay tuned!
