App Service

This project defines an App model and associated services for managing application metadata. It includes a Go data model and a Protocol Buffers definition for gRPC communication.

App Model (app.go)

The App struct defines the data model for applications:

Field	Type	Description
ID	uint32	Unique identifier for the app (auto-incremented)
Name	string	Name of the app (must be unique and at least 2 characters)
Version	string	Version number of the app
Url	string	URL associated with the app
IsActive	bool	Status of the app (active/inactive)
CreatedAt	time.Time	Timestamp of when the app was created
UpdatedAt	time.Time	Timestamp of the last update
CreatedBy	uint32	ID of the user who created the record
UpdatedBy	uint32	ID of the user who last updated the record

gRPC Service (app.proto)

The .proto file defines a gRPC service for interacting with App records. The core service and messages include:

Messages

• App: Mirrors the structure of the Go App model.
• AppId: A request message containing an app ID.
• AppList: A list of App messages.
• AppRequest: Request to create or update an app.
• AppResponse: Response containing an App.
• Empty: A placeholder message for methods that don’t require input.

Services

• CreateApp(AppRequest) returns (AppResponse)
• GetApp(AppId) returns (AppResponse)
• ListApps(Empty) returns (AppList)
• UpdateApp(AppRequest) returns (AppResponse)
• DeleteApp(AppId) returns (Empty)

These services enable full CRUD (Create, Read, Update, Delete) operations on the App entity.
