Your team realizes that testing is valuable. Your team creates tests for already completed features. The result was encouraging and your team even found a few bugs hiding in the application. Your team returns to feature development and attempts to add new tests.
Your software development team released an MVP application into production. The application only had a few features and the codebase is far from perfect, but there are big plans for the future! Your team presses on, adding features and your user base continues to grow. After a few months, cracks begin to surface.
Introduction Now that we’ve demystified smart contracts and better understand what they are and how they work, let’s build our own contract on top of the Ethereum blockchain. Because smart contracts are computer programs at their core, many of the concepts that we’ll use to build a basic contract will seem familiar.
Smart contracts are often described as a transformative new technology that borders on magic, able to remove third-parties and monetary risk alike from business deals using the power of the blockchain.
It’s been a year since I last talked about my development environment. Many things remain the same: I’m using neovim, zsh, and tmux. However, I have made a few changes to improve usability and make my day-to-day work feel faster.
What is Software Architecture? Software architecture is the analysis, thought and design considerations that form the foundational scaffolding for a successful software system. If you write software for work or as a hobby, whether you know it or not, you’re already dealing with software architecture and the processes of making architectural decisions within your applications.
TypeScript has become a mainstay of modern web development libraries. Consuming functions and widgets written by a third party can be error-prone without some type of guidance. Introducing static typing to the interfaces doesn’t just reduce misuse, it has added benefits including intelligent code completion.
In an olympic sprint relay, four runners operate as a team to sprint a total of four hundred meters. In order to compete at a record-setting level, an athlete needs to be capable of running one hundred meters in less than ten seconds.
“What problem are we trying to solve?” As a career business analyst, I’ve lost count of the number of times I’ve asked this question. More often than not, stakeholders are ready to discuss solutions before dissecting the problem itself.
This is part 3 of the Disciplined Engineering series. It is for teams that have an established engineering process with confidence around the quality of their application. This article will help improve your engineering game by identifying the common patterns that will further improve your team’s focus on quality.
This is part 2 of the Disciplined Engineering series. It focuses on improving the confidence of the code produced by your team. If you haven’t already, we recommend reading Part 1: Building an Engineering Process as a prerequisite for these practices. You can also check out Part 3: Refining Your Engineering Process.
This is part 1 of the Disciplined Engineering series. It is for teams that want to establish a culture of engineering excellence for their organization. For teams that already have an established process, we recommend reading Part 2: Creating Code Confidence.
Snapshot testing has become very popular for front end-development over the last few years. The term has almost become synonymous with Jest and React, but it can be used to test more than just components.
The recent TypeScript 3.9 release primarily focuses on performance and stability, but it does include some language updates that are worth a closer look. Expansion of uncalled function checks Continuing its quest to save you from yourself, TypeScript 3.9 expands on the uncalled function checks that were introduced in version 3.7.
There’s an old adage in the software industry – premature optimization is the root of all evil. A corollary to this should be – no optimization is just as bad as premature optimization.
As accessibility-minded developers working on accessibility-minded teams, we strive to design and build inclusive applications that yield a pleasant experience for all users. However, despite our best efforts we may make mistakes and implement features in a sub-optimal way, or worse, discover that some users cannot use those features at all.
Virtual reality (VR) is one of the most interesting emerging technologies for the web in 2020. Recently at HalfStack Phoenix I shared insights on VR, WebVR, the web, and what makes VR a lasting technology that will change the way we interact with information over the coming decade.
SitePen is a huge advocate for TypeScript and the benefits of having well typed code. TypeScript is especially powerful when used by medium and large teams that want to find ways to increase their overall confidence in their code.
What is React Native React Native is a JavaScript framework for writing hybrid native mobile applications for both iOS and Android platforms.
Event sourcing is a powerful architectural pattern that records all changes made to an application’s state, in the sequence in which the changes were originally applied.
