Golang and Express excel in high-performance scenarios, while Laravel, Lumen, and Django prioritise developer experience and feature completeness Choosing the right web framework for your project is a critical decision that can significantly impact the success of your project. Developers have a plethora of options available, each with its own set of advantages and trade-offs. In this benchmark comparison, we’ll evaluate five popular web frameworks: Golang Fiber, Node....

Error handling is an essential aspect of robust software development. In Go, error handling is straightforward yet powerful, thanks to the built-in panic and recover mechanisms, along with the ability to wrap errors for improved context. In this article, we’ll explore these error handling strategies in detail, along with comprehensive code examples. 1. Panic and Recover What is Panic? panic is a built-in function in Go that stops the ordinary flow of control and begins panicking....

Enable GZIP Compression on Ubuntu + Apache GZIP compression is a technique used to reduce the size of files transmitted over the internet, which can significantly improve website performance and decrease load times. In this article, we will guide you through the steps to enable GZIP compression on an Ubuntu server with Apache. Step 1: Check if mod_deflate is installed Before proceeding, we need to check if the mod_deflate module is installed and enabled in Apache....

Node Version Manager (NVM) is normally installed for a single user, typically under ~/.nvm. This works well for development environments, but it can become problematic on servers where multiple users or services need Node.js. For example, on an Ubuntu server you may need Node.js for: Jenkins CI/CD jobs Supervisor-managed applications www-data Deployment scripts Regular SSH users A better approach for this scenario is to install NVM in a shared system location such as /opt/nvm....

In Go, interfaces play a significant role in achieving polymorphism and abstraction. They define a set of method signatures that a type must implement to satisfy the interface contract. In this article, we’ll delve into what interfaces are, why they are useful, explore the concept of empty interfaces, and discuss some common useful interfaces in Go, accompanied by comprehensive code examples. What is an Interface in Go? An interface in Go is a type that specifies a set of method signatures....

Jenkins normally runs shell commands as the jenkins user. However, some server-maintenance tasks require root privileges—for example, cleaning APT caches, removing old packages, or managing system files. A common but unsafe approach is to give the Jenkins user unrestricted sudo access: jenkins ALL=(ALL) NOPASSWD: ALL This allows Jenkins jobs to execute arbitrary commands as root. A much safer approach is to allow Jenkins to run only one specific maintenance script as root....

Bootstrap is a popular CSS framework that provides a set of ready-to-use components and styles for building responsive web applications. In this article, we will explore how to enable Bootstrap Tooltip in an Angular application using an attribute directive. Install Bootstrap: npm install bootstrap Import Bootstrap SCSS in styles.scss: // For Setting Project Specific Bootstrap Variable. Like $primary Color @import "assets/scss/variables.scss"; // Import Bootstrap @import "../node_modules/bootstrap/scss/bootstrap.scss"; // App Specific components @import "assets/scss/app....

Concurrency is a powerful aspect of Go (Golang) that allows developers to execute multiple tasks concurrently, enabling efficient resource utilization and improved performance. In this article, we’ll explore two key concurrency primitives in Go: goroutines and channels. Understanding Goroutines Goroutines are lightweight threads managed by the Go runtime. They enable concurrent execution of functions or methods independently of other parts of the program. Goroutines are more lightweight than operating system threads, allowing Go programs to create thousands or even millions of them without significant overhead....

Laravel, an open-source PHP framework, provides built-in functionalities for developers to write tests for their applications. However, running tests, especially database tests, can sometimes be slow and time-consuming, affecting the productivity of developers. This blog post will elaborate on how to speed up Laravel unit tests using the schema::dump command. The Problem While performing unit tests in Laravel, developers often face a problem: migrations. Each time you run a test, Laravel runs all migrations, creating a database schema....

The Singleton pattern is a creational design pattern that ensures a class has only one instance and provides a global point of access to that instance. While Go does not have traditional classes like object-oriented languages, it does allow for the implementation of the Singleton pattern using various approaches. We are going to use Goroutines in testing our approaches in Multi-threading. In this article, we’ll explore different approaches to implement the Singleton pattern in Go, along with code examples....
