Golang News, Tutorials, Go Libraries and Golang Jobs
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 […]
Wails to the Golang GUI framework! Today marks the release of Wails v2. It’s been about 18 months since the first v2 alpha and about a year from the first beta release. I’m truly grateful to everyone involved in the evolution of the project. Part of the reason it took that long was due to wanting to […]
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 […]
ko is a simple, fast container image builder for Go applications. It’s ideal for use cases where your image contains a single Go application without any/many dependencies on the OS base image (e.g., no cgo, no OS package dependencies). ko builds images by effectively executing go build on your local machine and as such, doesn’t require docker to be installed. This […]
An embeddable high-performance MQTT broker server written in Golang supporting distributed cluster, and compliant with the MQTT v3.0 and v3.1.1 and v5.0 specifications for the development of IoT and smarthome projects. The server can be used either as a standalone binary or embedded as a library in your own projects. CoMQTT message throughput is comparable […]
Processing user-uploaded files is a common task in web development, and you’ll likely need to develop a service that handles this task from time to time. This article will guide you through running file uploads on a Golang web server and discuss standard requirements such as multiple file uploads, progress reporting, and restricting file sizes. […]
You’ve likely heard and read dozens of stories about generics in Go about ordinary slices and maps but haven’t yet thought about a fun way to apply this feature. Let’s implement the peer of pandas.read_html, which maps HTML tables into slices of structs! If it’s achievable even with Rust, why shouldn’t it be with Go?! This essay will show […]
