Core API Structure

This section covers common structural elements, aiming to be the organizational foundation of your REST-ful API. It ensures that your project cleanly separates resources and their contexts and offers explicit rules for paths, actions, and errors. This structure is designed to be simple, easy to understand, and easy to implement.

A clear and consistent structure brings numerous benefits. It ensures that all APIs follow the same design principles, making them easier to understand and use. Scalability is achieved by maintaining consistent foundational elements, allowing for the seamless addition of new features and services. Standardized patterns for paths, actions, and errors simplify maintenance and updates, reducing bugs and inconsistencies, which enhances maintainability. Improved collaboration among developers is facilitated by clear structure and guidelines, reducing onboarding and code review time. Additionally, a consistent and well-structured API improves ease of interaction, leading to enhanced user satisfaction.

Or, in plain talk: If everything follows the same rules, you can implement it once it in a shared library and move on to worrying about your business logic instead.


Resource Entities

The required fields and naming conventions for all resources in the API.

Error Format

The response format and structure for all error messages.

Domain Names

A clear and organized domain name strategy, explicitly separating functional areas via using subdomains.

Path Patterns

This section covers rules around paths and resource addressing in API’s.

CRUD Operations

The constraints for all Create, Read, Update, and Delete operations in the system.

Standard Endpoints

Every resource server must provide a set of standard endpoints to ensure that clients can discover and interact with the service.
