Go Web Service

This is a sample server for a Go web service.

Getting Started

Prerequisites

• Go 1.21 or higher
• PostgreSQL
• .env containing : PORT, DB_STRING, SECRET_KEY

API-Definition

• Redirects all endpoint of /swagger/ to swagger/index.html (httpSwagger.handler of go get github.com/swaggo/http-swagger/v2)

How it was created

• Generates API definition from Annotations using swaggo/swag/cmd/swag@latest (go install github.com/swaggo/swag/cmd/swag@latest)

$ > swag init ./ --parseDependency

<!-- This will create Swagger API definition in docs/swagger.json -->
<!-- flag parseDependency is used as some endpoints types are not go-predeclared types, they are customized types from sql library for Null Values Detection -->

API-Testing

• Manual testing can be done through swagger 2.0 API documents.

Design Patterns

• Chain of Responsibility : Middleware
• Dependency Injection : Singleton database connection + Pgxpool concurrency supported
