Building A Go Crud Rest Api From Scratch
Blog post from Keploy
A comprehensive guide details the process of building a CRUD API using Go, employing tools such as Mux for routing, Postgres for database management, and Docker for containerization. The guide outlines the creation of a Go application with five endpoints for basic CRUD operations, including creating, reading, updating, and deleting entries. It explains how to set up the development environment, including initializing a Go module, installing necessary dependencies, and structuring the project files with Docker and Docker Compose configurations. The tutorial further describes connecting the Go application to a Postgres database, creating tables, and handling HTTP requests using Mux. Detailed instructions are provided for Dockerizing the application, building Docker images, and setting up a Docker Compose file to manage both the Go application and the Postgres database as services. The guide culminates with testing the application using tools like Postman and TablePlus to ensure proper functionality and database connectivity.
