What is difference between flask and FastAPI?

Flask is a Python web framework for building web applications. Fast API is a high-performance web framework for building web applications with Python 3.6+ based on standard Python type hints. It is designed to be high performance and easy to learn.

Is FastAPI really fast?

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. The key features are: Fast: Very high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic). One of the fastest Python frameworks available.

How good is FastAPI?

In conclusion, FastAPI is a fast web framework with support for asynchronous code and has very good documentation. The pros of FastAPI outweighs the cons by a great margin, and I highly recommend you check it out.

Is FastAPI restful?

A REST API is an architectural pattern for creating web services. REST APIs are stateless, cacheable, and consistent. They’re great for building general-purpose and scalable web applications. The three major Python frameworks are Django, Flask, and FastAPI.

Is FastAPI easier than flask?

Flask is easy and straightforward and has many online materials and resources as well, while Fast API is the easiest if you’re starting with web development but has the fewest online resources.

Is FastAPI ready for production?

The example above about Named Entity Extraction with spaCy and FastAPI can almost be considered as production-ready (of course the API code is only a small part of a full clustered application). So far, FastAPI has never been the bottleneck in our NLPCloud.io infrastructure.

Why is FastAPI fast?

It is a modern framework that allows us to build API seamlessly without much effort and time. As the name itself is fast, it is much faster than the flask because it’s built over ASGI (Asynchronous Server Gateway Interface) instead of WSGI (Web Server Gateway Interface) s the flask is built on.

Should I use fastapi instead of flask?

Based on all the factors, I would suggest adopting FastAPI over Flask. It is very easy to set up, migrating an old flask project into this won’t take much time, async, web sockets, and automatic docs generation feature is the cherry on top.

What is fastfastapi and why should I Care?

FastAPI allows you to do this at the level of path operation functions, i.e. your API routes. This is an area where Flask is very weak. With Flask, you will often find yourself exporting globals, or hanging values on flask.g (which is just another global).

Should I use Django or fastapi for my project?

If you’re looking to build APIs (especially for microservices), FastAPI is a better choice than Flask. The only reason not to use it would be if your organization already has a lot of tooling built around Flask. If you’re building something that is a lot of server-side rendered HTML, or a CMS, then Django is probably still the way to go.

What is flask in Python?

Flask is currently the primary choice of writing APIs for machine learning frameworks in Python. It is a framework based on the current/old standard for Python web frameworks: WSGI. Like most widely used Python libraries, the Flask package is installable from the Python Package Index (PPI).
