Hanlder Status Codes HTTPS for Express

This module provides a class to handle HTTP responses for Express, using standard status codes. The ResponseStatusHTTPS class makes it easy to create consistent and structured responses for different situations in a web application.

Objective

The main goal of this module is to provide a standardized and consistent way to manage HTTP responses in an application. The implementation of this class is guided by SOLID principles and design parameters to:

Keep code clean: Providing clear and specific methods for each type of response, avoiding code duplication and promoting reuse.
Ensure scalability: Allowing easy addition of new types of responses or modification of existing ones without affecting other parts of the system.
Ensure high quality: Applying design principles that improve the readability and maintainability of the code.

Examples in Service

First Option

 
 async getByid(id: number): Promise<ServiceResponse<users>> {
        try {
            const user = await prisma.users.findUnique({ where: { id: id } })
            if (!user) {
                return ResponseStatudsHTTPS.notFound(`User not found`)
            }
            return ResponseStatudsHTTPS.succes(user)
        } catch (error: any) {
            return ResponseStatudsHTTPS.errorServer(error.message)
        }
    }

Second Option

async getByid(id: number): Promise<ServiceResponse<users>> {
      try {
          const user = await prisma.users.findUnique({ where: { id: id } })
          if (!user) {
              return ResponseStatudsHTTPS.createResponse({status:Code.NOT_FOUND, message:"User not found"})
          }
          return ResponseStatudsHTTPS.createResponse({status:Code.OK, data:user})
      } catch (error: any) {
          return ResponseStatudsHTTPS.createResponse({status:Code.INTERNAL_SERVER_ERROR, message: error.message})
      }
  }

Examples in Controllers

  public async getByid(req: Request, res: Response) {
        const { id } = req.params
        const result = await this.service.getByid(Number(id))
        return res.status(result.statusCode).json(result.body)
    }

Interface

interface ServiceResponse<T> {
    statusCode: httpsStatusCode; //Export Enums
    body: {
        message?: string;
        data?: T;
    }
}

Handler Error for NestJs

public async getByid(id: number): Promise<User> {
       try {
           const user = await prisma.users.findUnique({ where: { id: id } })
           if (!user) {
               throw new ErrorManager({ type: "NOT_FOUND", message: "User not found" })
           }
           return user
       } catch (error: any) {
           throw new ErrorManager.createSignatureError(error.message)
       }
   }
