Testing Commander.js command line applications

Breaking changes in production are inconvenient and can be costly to fix. Using commands like git clone < some GitHub repository >, executed on your terminal is a common practice, known as using the command line. This practice can be faster and more efficient than using a GUI. For this tutorial, I will walk you through the process of testing command-line applications git, explain why you need command-line applications, and describe in detail how they work.

How to review your CircleCI configuration

Configuration files can take some time to set up, but after that initial push they are easy to forget about. “If it’s not broken, don’t fix it” is a common approach that many developers take with their configuration files. But when it comes to your continuous integration pipelines, small changes can have huge benefits.

Continuous integration for a production-ready Dockerized Django application

Continuous integration has become a widely accepted practice for software projects. As more technologies are introduced in both continuous integration and software development, developers are looking for practical ways to benefit from them. Basic tutorials that cover toy examples are not always enough for real-life practitioners. As an actual user of Django, Docker, and CircleCI, this was certainly a pain point for me. That is why I wrote this tutorial.

Data structures for effective Python applications

Because computers rely on data to execute instructions, computing will always entail data interaction. The amount of data can be overwhelming in real world applications, so developers must consistently devise methods to access it quickly and efficiently in a programmatic way. A solid understanding of data structures is a great advantage for teams that specialize in developing tools and systems. Organizing data optimally maximizes efficiency and makes data processing easy and seamless.

Deploying a Laravel application to Heroku

In this tutorial, I will show you how to set up a continuous deployment pipeline to deploy a Laravel application to the Heroku platform with minimum hassle. Automating deployment helps teams limit human intervention during the deployment process, reducing the risk of errors and streamlining the entire software release process.

Serverless vs containers: Which is best for your application?

To keep ahead of the curve, many organizations are looking at how to evolve their technical processes to accelerate their IT infrastructure development. Fast and robust deployments to the latest platforms are key to achieving the low lead times that enable this evolution. Two of the most widely-used technologies to host these deployments are serverless functions and containers. What are they, how do they differ, and how do you decide which is best for your application?

Testing Flask framework with Pytest

Writing tests in any programming language can be difficult, but it does not have to be. In this tutorial, I will show you how you can easily write and run tests using Flask and Pytest. As a bonus, we will also integrate a CI/CD pipeline to run tests on a Flask app using CircleCI. Be sure to check out our other Flask tutorials to learn about application logging, authentication decorators, and automating Flask deployments.

DevOps for startups

It is an exciting time to be a startup. Our vast technological landscape has made powerful digital tools available to businesses of all sizes, making starting (and scaling) an organization easier than ever before. In an era where technology is a fundamental building block of almost every business, methodologies like DevOps have become ubiquitous across many industries.
