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?
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.
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.
If you are new to Docker, you may find it challenging to understand all the terms. It can seem like everyone has a different idea of what Docker terms mean, and sometimes, terms get used interchangeably. For instance, you — like others who are learning about Docker — may wonder how a Docker image differs from a Docker container. Their contrasts are subtle but significant.
React continues to be the web framework of choice for many UI developers, surpassing jQuery as the most popular framweork in the 2021 Stack Overflow Developer Survey. It provides an intuitive model for building data-driven user interfaces, and efficiently updates the DOM when this data changes. React pairs nicely with Redux for managing the data that React needs to render interfaces. Redux offers a predictable way to structure and update the data in those frontend applications.
Gin is a high-performance HTTP web framework written in Golang. It contains features and functionalities like routing and middleware out of the box. This helps to reduce boilerplate code, improves productivity, and simplifies the process of building microservices. In this tutorial, I will guide you through the process of building a RESTful API with Golang using the Gin-gonic framework. I will also lead you through building an API to manage the basic details of a company.
Most organizations that make software — from small startups to multi-billion-dollar behemoths — use third-party libraries and tools to develop their applications. Modern apps depend on many external components to build and deliver software to customers. These libraries and tools are collectively called the software supply chain. A software supply chain for a typical web app may include components like these.
Axios is a promise-based HTTP library that lets developers make requests to either their own or a third-party server to fetch data. It offers different ways of making requests such as GET, POST, PUT/PATCH, and DELETE. In this tutorial, I will explain how Axios interacts with applications, describe the structure of Axios requests and responses, how to make requests to an API, and how to write tests for your requests using CircleCI.
