How To: Create a Flask API with JWT-Based Authentication (Overview)

How To: Create a Flask API with JWT-Based Authentication

New Tutorial Series! This tutorial series provides step-by-step instructions and in-depth explanations to guide you through the process of creating a robust, production-quality REST API. The toolstack consists of Flask, Flask-RESTx, pyjwt, SQLAlchemy and other packages. Code quality is a major focus, with considerable time dedicated to testing (using pytest), logging and tools such as coverage, flake8 and mypy. The tutorial concludes by creating a process that continuously integrates (with tox, travis/circle CI, coveralls) and deploys the API (with either Github or Azure DevOps to Heroku).

An Introduction to Decorators in Python

An Introduction to Decorators in Python

Feb 27 2020 — Decorators can be a daunting topic when first encountered. While the Zen of Python states “There should be one– and preferably only one –obvious way to do it”, there are many, equally valid ways to implement the same decorator. These different methods can be categorized as either function-based, class-based, or a hybrid of both. In this post I will explain the design and behavior of Python decorators and provide examples of decorators that I frequently use in my own code.

Hugo: Add Copy-to-Clipboard Button to Code Blocks with Vanilla JS

Nov 13 2019 — Hugo includes a built-in syntax-highlighter called Chroma. Chroma is extremely fast since it is written in pure Go (like Hugo) and supports every language I can think of. Chroma’s speed is especially important since syntax highlighters are notorious for causing slow page loads. However, it lacks one vital feature — an easy way to copy a code block to the clipboard. I decided to document my implementation using only vanilla JS since every blog post I found for this issue relied on jquery to parse the DOM, which is a shame. We can do better, people.
