Implementing CRUD in GoLang REST API with Echo & GORM

In this article, we will learn about implementing CRUD in Golang REST API with Echo for routing requests, GORM as the ORM to access the database, Viper for Loading configurations, and PostgreSQL as the database provider. We will also follow some clean development practices to help organize the GoLang project folder structure in a more easy-to-understand fashion.

Config your own Golang

• Create your own database on PostgreSQL Server
• Rename config.json.example to config.json
• Change the value of 'connection_string' in the config file:

{
  "connection_string": "user=username password=yourpassword dbname=yourdb host=localhost port=5432 sslmode=disable TimeZone=Asia/Singapore",
  "domain": "http://localhost",
  "port": 8080
}

Up to date the dependencies version (Recommended)

go get -u

Or only download current dependencies version (Not Recommended)

go get

Run on local/dev mode

go run .

Build

go build -o file_name

Run Build at Terminal

./file_name

Test Rest API

Install plugin on vscode named: REST Client or others like 'ext:rest'
Test the rest API at folder:

~/golang-crud-rest-api/collection/products.rest
