Create API Response Format

[jealapera]

Standardize the API response format for all existing API endpoints within the project, ensuring uniformity and ease of consumption across the entire API.

• Utilize Node.js and Express.js to integrate the standardized response format into all API endpoints, leveraging the existing setup.
• Enhance middleware functionality to effectively manage incoming requests and enforce the standardized response format seamlessly.
• Refine the response format across all API endpoints to include standardized fields such as status, message, and data.
• Strengthen error handling mechanisms to manage and address potential errors encountered during request processing for all endpoints.
• Review and adjust the inclusion of relevant data in the response payload to meet the specific functionality and requirements of each API endpoint.

Every end point should have a standard API Response or Result in (Postman for example).

For Success Response/s { "error": false, "code": 200, "message": "User registered successfully.", "data": "token (this should be long text with alphanumeric)" }

For Error Response/s { "error": true, "code": 400, "message": "Email already registered." }
