Building End to End REST APIs in Flask and Connexion

onlinejudge95


Description:

With the advent of the cloud, APIs are emerging to expose web services. REST is a logical choice for building APIs that allow users to connect and interact with cloud services. A RESTful API explicitly takes advantage of HTTP methodologies defined by the RFC 2616 protocol. With flask already holding the center stage for developing web services in the Python ecosystem, how good it would be if we can use flask to build REST APIs and expose our web service through them.

We will implement a Service that would act as a bot for introducing new members in a Github organization. We will write our server using flask and provide REST APIs for clients with connexion(using swagger specifications) to interact with. We will write unit tests for our APIs and try to improve their code coverage. After we have finished finalizing our codebase, we would dockerize it(if time permits we can try minimizing our docker image's size).

Basic Outline of the talk

  • We will start with an overview of what REST is.
  • A brief introduction of flask and it's structural overview.
  • How to code specification driven APIs.
  • Unit testing our APIs.
  • Improving our code quality.
  • Dockerizing our app for deployment.

Who is this talk for

  • Python web developers.
  • Developers who build services that need to be consumed by multiple clients.
  • Anyone interested in exposing their web services through REST APIs.

Key Takeaways

  • Implementing a REST API in Flask.
  • Unit testing our APIs to make the deployment smoother.

Prerequisites:

Knowledge of Python3 is required(remember to bid farewell to python 2.x).

Speaker Info:

I work as a Dev-Ops engineer in Amazon.in and have over 2 years of experience in Web Services. Graduated in 2017 from Kamla Nehru Institute of Technology with a Bachelor's degree in Computer Science and Engineering. Developing and consuming my own APIs for almost a year now. I prefer a raspberry pi over the cloud to host my home-scale services for personal use. In my free time, I prefer stargazing. Currently working on combining the power of python to solve amateur astronomy problems.
