Create Local JSON Server to Create Rest API

 1. Install Node.js

Ensure you have Node.js installed on your machine. You can check this by typing node -v in your command terminal. [1]

2. Initialize your project

Open your terminal, create a new directory for your project, and navigate into it:

bash

mkdir my-mock-api
cd my-mock-api
npm init -y

3. Create the JSON file

Create a file named db.json in your project root. This file acts as your database, where every top-level key automatically generates its own API endpoint. Add some sample object arrays into it: [1, 2]

json

{
  "users": [
    { "id": "1", "name": "Alice", "email": "alice@example.com" },
    { "id": "2", "name": "Bob", "email": "bob@example.com" }
  ],
  "posts": [
    { "id": "1", "title": "First Post", "userId": "1" }
  ]
}

Use code with caution.

4. Start the JSON Server

You can launch the server instantly using npx (which downloads and runs the tool on the fly): [1]

bash

npx json-server db.json

Use code with caution.If you prefer to run it globally or locally inside your development environment, you can install it using npm: [1]

bash

# Optional: Install globally
npm install -g json-server

# Run the server with watching enabled
json-server --watch db.json
