To Unmarshal() or To Decode() for JSON? If you are like me and want to learn backend development, you probably came across JSON handling at one point. JSON is a very popular format for transferring data between the front and backend. Because it is such an essential feature in modern web development, Golang adds support […]
Learn how to build a Golang Lambda service in a container, hook it up to a REST API end-point, and push and pull data from S3. The Goal of this Golang Lambda Project Here is the plan when I make a call like this: >_curl https://earthly-tools.com/text-mode?url=https://www.lipsum.com/ It will 1) hit the API gateway, 2) call my GoLang lambda function […]
Recently the author has been building a fully internationalized (i18n) and localized (l10n) web application for the first time with Go’s golang.org/x/text packages. I’ve found that the packages and tools that live under golang.org/x/text are really effective and well designed, although it’s been a bit of a challenge to figure out how to put it all together in a […]

Trade-offs between dependency management and change control When you take the first step into the software world, it is almost impossible not to encounter the term DRY (Don’t Repeat Yourself). This is because we’re using functions, abstractions, etc., not to repeat ourselves in our projects. However, is this idea always valid in every situation? For example, think […]
A misconception among many developers is believing that a concurrent solution is always faster than a sequential one. This couldn’t be more wrong. The overall performance of a solution depends on many factors, such as the efficiency of our code structure (concurrency), which parts can be tackled in parallel and the level of contention among […]
Accessing an e-mail account anywhere in the world on any device requires authenticating yourself to prove the data associated with the account (e.g., e-mail address and inbox messages) belongs to you. Often, you must fill out a login form with credentials, such as an e-mail address and password, that uniquely identify your account. When creating […]
If you’ve been working on a product or business, a recurring scenario that happens is the changing business requirements. Developers build a solution based on a set of conditions. Over time these logical conditions might change due to changing business needs or other external market factors. Rule engines are a powerful way to solve such problems. In […]
I’m a fan of personal projects. Throughout the years, I have had the pleasure of writing multiple database-related blogs/GitHub projects. Now, I’ve decided I want one project to rule them all! I’ve implemented my database in Golang and decided to share my knowledge by writing a blog post describing all the steps. This post is […]
When you start to build web applications with Go, one of the first questions you’ll probably ask is “which golang router should I use?” It’s not an easy question to answer, either. Probably more than 100 different routers are available, all with different APIs, features, and behaviors. So for this blog post I’ve evaluated 30 […]
