Hello Developers 👋. Authorization is a key part of every system we built and Casbin is one common name we hear in every language for authorization.

Casbin currently has its support for Golang, Java, C/C++, Node.js, Javascript, PHP, Laravel, Python, .NET (C#), Delphi, Rust, Ruby, Swift (Objective-C), Lua (OpenResty), Dart (Flutter), and Elixir.

In this article, My goal is to demonstrate the working of casbin and its different available model configurations in a simple and understandable flow.

If you already know the basics of casbin and just need the implementation flow of casbin in golang, you can check my other…

Hello Developers 👋. In this article, I will demonstrate how we can set up Database Transaction for multi-layer controller-service-repository pattern Golang projects.

What is the need for DB Transaction?

Transactions in Database come into a picture when we need to perform multiple DB operations but still treat them as a single unit. A transaction in a database system must maintain Atomicity, Consistency, Isolation, and Durability − commonly known as ACID properties − in order to ensure accuracy, completeness, and data integrity.

We can implement DB transactions in gorm as follows

Though implementing transactions seems simple, it can be troublesome to set up when the project is…

Hello Developers 👋. In this article, I will demonstrate how easily we can deploy the Next.js Application on Google App Engine within minutes.

Visit my other article if you want to deploy your Next.js Application on Firebase Platform using Cloud Function with Firebase Hosting.

2. Preparing a basic Next.js App

Let’s prepare a simple Next.js application to deploy on the google app Engine.

npx create-next-app

Hello Developers 👋. Analytics has been a very essential tool for us. It helps us to get a deeper understanding of our customers. But it was not very straightforward to be used with the Nextjs Application when I tried it. So In this article, I will demonstrate how easily Analytics can be integrated with the Nextjs Application.

Firebase Setup (Part 1 — on Firebase Console)

Let’s start by setting the Firebase project by going to the firebase console.

Hello Developers 👋. In this article, I will demonstrate how we can make use of UUID and Binary(16) datatype in gorm v2 and golang.

What is UUID?

A UUID is just a 128-bit value and it is usually represented in human-readable format as an UTF8 string composed of 5 groups of hexadecimal charac ters separated by dashes.

Example: cef4c20c-30cf-11eb-9242–9822ef9cf075

Pros of using UUID instead of AUTO_INCREMENT PRIMARY KEY?

1. They are unique across tables, databases, and servers.
2. They are hard(er) to guess from URLs.

Cons of using UUID:

1. Increased Storage i.e. 36 characters and thus performance issues.
2. It is more difficult to debug.

Looking at the both pros and…

Hello Developers 👋. Today I will try to demonstrate how the social media preview works and how I implemented on my recent next.js project. Before going any further on implementation, let's create a simple next.js project.

npx create-next-app

I will name the project as next-social-media

Before going for the implementation let's first talk about the need for docker briefly.

Common Problem that Every Developer Face

1. Overview

Deploying static websites like React Applications on the Firebase Platform is very straightforward. But that was not the case with Next.js Projects. This is because Next.js Application requires a server to handle server rendering. So deploying just static HTML is not sufficient. Here in this article, I will demonstrate the deployment of a Next.js project to the firebase platform using cloud Function and Firebase Hosting.
