appmetadata-go

To build this app, I have referred following docs,

1. https://go.dev/doc/tutorial/web-service-gin.html
2. https://gin-gonic.com/docs/testing/

Code for this application is organized into model, controller, dao and service packages. Tests are in their corresponding test packages. This app facilitates following API calls,

1. GET /appmetadata This returns current appmetadata persisted in memory
2. GET /appmetadata/:title This return all the metadata records that match with title
3. POST /appmetadata This takes payload of type model.App_metadata and after validations, persist it in existing in memory App_metadata datastructre
