Building and using a mock API server is a common practice in software development, especially during the early stages of a project or when integration with a real backend is not available. Mock API servers simulate the behavior of a real API, allowing developers to test their applications without relying on the actual backend services. Here's a step-by-step guide on how to build and use a mock API server:

Building a Mock API Server:

Step 1: Choose a Mock Server Tool

There are several tools available for creating mock API servers. One popular option is `json-server`. You can install it using npm:

npm install -g json-server

Step 2: Create a Mock Data File

Create a JSON file containing the mock data you want to serve. Save it as `db.json`:

Step 3: Start the Mock Server

Run the following command in the terminal to start the `json-server`:

json-server --watch db.json


Your mock API server is now running at `http://localhost:3000`.

Using the Mock API in Your Application:

Remember to consult the documentation of the specific mock server tool you choose for more advanced features and options.
