ℹ️ Introduction

• Product API for CRUD operations.
• Written in GoLang and PostgreSQL. Bearer token authentication is used.
• Database connection is made with GORM. Server is created with gorilla/mux.
• I am just making this project for learning purposes. I am open to any suggestions and contributions.
• Project can be evolved with adding new features and tests.

💾Installation Guide

• To clone and run this application, you'll need Git, Go, PostgreSQL installed on your computer. From your command line:

  # Clone this repository
  $ git clone https://github.com/Ctere1/golang-api
  # Go into cmd folder
  $ cd cmd 
  # Run the app
  $ go run main.go

• You can change the database connection string in the app.toml file. Also, you can change the API listen address and port.

  After these steps, you can use the API with Postman or any other API testing tool.
