JSON Server is a simple and lightweight npm package that allows you to quickly set up a REST API with CRUD operations using a JSON file as a database. It is commonly used for prototyping, mocking APIs, and front-end development, providing a fast and easy way to simulate a backend server without the need for a full-fledged database.
Nock is a powerful HTTP mocking and expectations library for Node.js. It allows you to simulate HTTP requests and responses, making it ideal for testing applications that make HTTP calls. With Nock, you can define custom HTTP endpoints, intercept outgoing requests, and mock responses to ensure consistent behavior during testing.

Functionality
json-server is a simple and lightweight package that allows you to quickly create a RESTful API server using a JSON file as a data source. It provides CRUD operations and supports filtering, sorting, and pagination. nock, on the other hand, is a powerful package for mocking HTTP requests in Node.js. It allows you to intercept and mock HTTP requests made by your application, making it useful for testing and simulating different scenarios.
Popularity
json-server is widely used and has gained popularity as a convenient tool for quickly mocking APIs during development. nock is also popular among developers for its ability to mock HTTP requests, especially in the testing community.
Ease of Use
json-server is very easy to set up and use. You simply need to create a JSON file with your desired data structure and run the server command. It requires minimal configuration and is suitable for simple API mocking needs. nock, on the other hand, requires more setup and configuration. You need to intercept and mock HTTP requests manually in your test code. While it provides more control and flexibility, it also requires more effort to set up.
Scalability
json-server is designed for small to medium-sized projects and is not suitable for high-performance or production-grade APIs. It is primarily intended for development and prototyping purposes. nock, on the other hand, can be used in a wide range of projects and scales well. It allows you to mock and simulate different scenarios, making it useful for testing complex interactions with external APIs.
Community Support
Both json-server and nock have active communities and are well-maintained. They have regular updates and bug fixes. However, json-server has a larger community due to its popularity and is more widely used in the development community.
