Building a Simple RESTful APIs Backend in Go using Gin Gorm and PostgreSQL

This article serves as a hands-on introduction to the powerful Gin web framework in Golang. You will learn to build a sleek RESTful APIs backend with a practical example.

Build RESTful APIs using Go and Gin

This article is the first of a series of articles where we will dive deep into building a full-fledged, scalable Go backend! This series will guide you through crafting robust REST APIs with Gin, containerizing with Docker, monitoring with Grafana and Prometheus, scaling with Kubernetes, carrying load testing with Hey and k6s, documenting with Postman, and deploying to AWS (think Beanstalk or ECS).

In this article, we will start by introducing Gin and building simple RESTful APIs. We will build a simple RESTful API to manage startups. It sounds more fun than the classic TODO list API, right?

Leeroy Jenkins! Let’s get started 🚀

Prerequisites

Before we start, let’s make sure you have the basics covered:

• Golang installed on your machine
• A Vercel account
• Postman installed

Introducing the Go and Gin Duo

Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance — up to 40 times faster. If you need smashing performance, get yourself some Gin.

• Speed and Efficiency: Go’s built-in concurrency features make it a natural fit for handling multiple requests simultaneously, leading to lightning-fast performance and efficient server utilization.
• Simplicity and maintainability: Gin’s minimalist design and intuitive API are like a breath of fresh air. It promotes code that’s easy to read, understand, and maintain, reducing the likelihood of errors and simplifying future updates.
• Robust Error Handling: Gin provides a framework for graceful error handling, ensuring that exceptions are caught and handled appropriately, leading to more stable and reliable APIs.
• Intuitive API and Developer Experience: Both Go and Gin offer straightforward syntax and well-structured APIs, making development more intuitive and enjoyable, even for those new to the…
