API (app Programming Interface) is the foundation of modern architecture.
They allow applications to be modularized and decoupled.
This allows you to create applications quickly and makes it easy to maintain them.
This article will teach you all about FastAPI basics.
What is FastAPI?
FastAPIis a Python-based web framework.
It has attracted a lot of attention in recent years.
FastAPI is simple to use, and itsdocumentationis clear and easy to follow.
FastAPI is used by tech giants such as Microsoft, Netflix, and Uber.
FastAPI has all the features you would expect from an API builder, but its not limited to these.
you’re free to use it to mount backward WSGI, which most users dont know about.
FastAPIs primary purpose is to buildAPI endpoints, as the name suggests.
This can be done as efficiently as returning Python dictionary data in JSON or using OpenAPIs interactive Swagger UI.
FastAPI does not limit itself to APIs.
FastAPI Installation
Here are the simple steps to install FastAPI on Linux or Windows.
You will also need an ASGI server.
So, install uvicorn using pip.
#2.FastAPI Installation on Windows
Install Python 3 on Windows using the Microsoft store.
This will also install pip.
Next, install FastAPI on Windows.
Finally, install ASGI server uvicorn.
This problem can be solved using OpenAPI, Swagger UI, and ReDoc.
These are automatically packed with FastAPI.
This allows you to concentrate on your code and not set up tools.
FastAPI uses Python 3.6 key in declarations (thanks to Pydantic).
This framework makes great use of it, giving you excellent editor support.
Pydantic already integrates validation into this framework.
Validation of standard Python types and custom field validations can be done.
This is an important part of any API.
We often just repeat the code, so why not incorporate some of it into our framework?
FastAPI does exactly this.
The library supports HTTP Basic, OAuth2 tokens (JWT tokens), and header API keys.
FastAPI, by default, supports asynchronous endpoints, making your code simpler and more efficient.
This is a significant advantage over Flask.
Flask can be useful if you should probably prototype an idea or create a simple web app quickly.
Flask and FastAPI are very different in the way they are used.
you’re able to quickly build a backend server using it without any coding knowledge.
FastAPI is simple to use, lightweight and can be used for small-scale web and utility development.
As previously mentioned, WSGI processes requests synchronously.
Requests are processed sequentially.
One cannot start until the last task is completed.
ASGI handles requests asynchronously.
This allows tasks to be completed at their own pace and does not require that they wait for others.
Another difference is the community.
Flask is a community that has existed longer than FastAPI.
This means great documentation and outside help from others who write about Flask.
FastAPI is still a new project, so the community has yet to grow quite as much.
This means that although there is enough documentation, there isnt much outside help.
FastAPI and Flask can quickly set upPython web serversand data science applications.
Both require the same effort for deployment, but which framework is best for your next project?
FastAPI is the best option when speed and performance matter most.
This framework is best if you are building a CDN and expecting significant traffic.
FastAPI allows you to download the framework and immediately use it.
The project template will save you time and help you save time.
FastAPI is a better option than Flask when you are building APIs.
This is especially true when microservices and other considerations are considered.
Flask is the best choice if you already have a lot of tools built around this framework.
Conclusion
So, that was all about FastAPI.
FastAPI offers superior speed and performance.
This framework is the best if you are building your content delivery data pipe and expecting traffic.
FastAPIs innovative framework and project template will help you save time.
Flask could be better for creating APIs, particularly microservices.
FastAPI is also better than Flask.
Flask is a better choice if you already use it extensively.
