JSON Server
JSON Server is a Node.js-based tool that creates a full fake REST API from a JSON file, allowing developers to quickly prototype and test front-end applications without a real backend. It automatically generates standard REST endpoints (GET, POST, PUT, DELETE) and supports features like filtering, pagination, and relationships. This makes it ideal for mocking APIs during development or for educational purposes.
Developers should use JSON Server when they need to rapidly prototype front-end applications, test API integrations, or simulate backend behavior without writing server-side code. It's particularly useful for front-end developers working on projects where the backend is not yet ready, for creating demos, or for teaching REST API concepts in tutorials and workshops.
