A Brief Introduction to Pagination
For many software engineers, endpoints for retrieving a list of entities are probably their favorite to implement–all they need to do is build an SQL statement that grabs all the available items, along with some other minor tasks. It’s all fun and games until the number of entities in the database becomes a bottleneck, where each GET request returns tens of thousands of items....A More Elegant Alternative to Golang's Error-Handling
Recently, I joined a new project at Colorkrew that uses Golang as its backend language. Almost everyone on the team, including myself, had no experience with Golang, so we had to start from zero. Learning Golang has been a rewarding experience so far. After all, it is one of the most in demand programming languages now....Separation of Concerns: Split Your React Components into Containers and Views
Many frontend engineers probably have experienced the head-scratching moment when their React components become so gigantic that they keep losing their train of thought when navigating through their frontend code. To salvage readability, one of the most common practices is to split up the humongous React components into smaller pieces. Traditionally, they would do this by chopping up the JSX elements....Sci-fi to reality: How fiction influences technology
Throughout my life I been captivated by many forms of fictional media. But in my career as a visual designer in the technical field, nothing offers greater inspiration than science fiction. To explain why it’s so important to me personally, it helps to establish a few things about my background…...RESTful API 101
It is almost impossible for a backend engineer to be oblivious to RESTful API in the 21st century, as it is one of the most popular API types. We can mostly attribute its popularity to its scalability, flexibility, and simplicity, all of which are highly sought-after qualities in modern APIs. If you also find these qualities desirable, you should consider building APIs following the RESTful principles....A sense of community in unfamiliar lands
The days and weeks leading up to my first day at Colorkrew I was of course brimming with excitement, but I’d be lying if I said I wasn’t nervous. It would be my first time living outside of my home country in a place that I’d only ever been to once for a week long trip 4 years ago....Introduction to Functional Programming
The first programming paradigm that most programmers in the 21st century learn is probably Object Oriented Programming (or OOP for short). Object Oriented Programming allows us to transform real-world entities into highly abstract models with descriptive properties and executable methods to simulate their behaviors in the real world. Despite its numerous advantages, such as readability, reusability, and maintainability, it also introduces immense complexity to state management....OAuth Demystified: A Straightforward OAuth Tutorial
Incorporating OAuth (short for Open Authorization) into an application might seem somewhat intimidating and disheartening for many entry-level software engineers. After all, they need to spend hours—or even days—implementing a complicated authentication process with the correct configuration, only to realize they have merely completed a tiny feature. Despite all the hard work it entails, OAuth is a safe and efficient way for users to grant websites and applications access to their personal information....Getting started with Design Systems
Hello, I’m Bryan and a little over three months ago I moved to Japan from Scotland to join Colorkrew’s design team! When I was a child I played with Lego for hours. These simple bricks brought so much joy to this future designer. _ _ This messy pile has endless potential, with just a little imagination....A Step Forward – becoming a software engineer in Japan
Dear Diary – An opportunity In October 2022, I embarked on my journey to Japan as a Japanese Language School student with the aim of starting anew in my professional career and evaluating my comfort level for potentially living here for the next decade. At that time, my proficiency in Japanese was limited to JLPT N4 certification, barely allowing me to engage in conversations or read signboards....Embracing AI and Ocean Breezes: A Recap of Developer Camp at Enoshima
This Developer Camp holds a special place in my heart as it was my inaugural experience attending a developer camp. Set against the picturesque coastline of Enoshima, Japan, this camp combined technical presentations, team activities, and beachside brainstorming sessions. Day 1: Arrival, Introductions, and Technical Insights: We arrived at Ofuna station, did a quick grocery trip to stock up....Async/Await: a Game Changer for Haters of Promise Chaining
If you became a frontend engineer after 2015, chances are that you have used or at least heard about Promise. As I have covered in my previous blog, Promise can help us specify sequential relations between operations in asynchronous programming in a readable and maintainable manner. Promise object in JavaScript has methods, such as then and catch, that can help us organize the sequential execution of operations in a pattern called Promise Chaining....Start of a colorful journey
As I sit here reflecting on my first three months at Colorkrew, I am filled with excitement for what the future holds. I joined the Biz team in January 2023. From day one, I was welcomed with open arms by my friendly coworkers and immediately felt a sense of belonging that was amplified by the fact that software that we developing is also the one we use in our everyday work....The Whys and Hows of Promise in JavaScript
If you have done any web development after 2015, chances are that you have heard of the concept of Promise. It wouldn’t be an overstatement to claim that Promise is ubiquitous in modern-day front-end codebases. However, many web developers—especially those who do not have much experience in front-end development—have been using Promise without thoroughly understanding its inner working....
