Bookstore REST API using Gin and Gorm

Read this article on understand how to build a sample golang app using Gin and Gorm.

To run and configure app to send data to SigNoz:

SERVICE_NAME=goApp INSECURE_MODE=true OTEL_EXPORTER_OTLP_ENDPOINT=<IP of SigNoz backend>:4317 go run main.go

should be without http/https scheme. Eg localhost:4317

This runs the gin application at port 8090. Try accessing API at http://localhost:8090/books

Below are the apis available to play around. The API calls will generate telemetry data which will be sent to SigNoz which can be viewed at <IP of SigNoz backend>:3000

GET    /books                    
GET    /books/:id               
POST   /books                    
PATCH  /books/:id                
DELETE /books/:id
