Mock GraphQL Server

A fake JSON server is a useful tool for testing front-end applications without needing to set up a real backend. One popular tool for this purpose is json-server. Here's a guide on how to set it up:

Setting Up a Fake JSON Server Using json-server

Prerequisites:

• Node.js installed on your machine.

Step-by-Step Guide:

1. Install json-server:

Open your terminal or command prompt and run the following command to install json-server globally: npm install -g json-server.

2. Create a JSON file:

Create a file named db.json in your project directory. This file will act as your fake database. Here is an example of what db.json might look like:

3. Start the server:

Run the following command in your terminal: json-server --watch db.json

This command starts a JSON server at http://localhost:3000 by default and watches for any changes in db.json.

4. Access the server:

• To get all posts: GET http://localhost:3000/posts
• To get a specific post: GET http://localhost:3000/posts/1
• To add a new post: POST http://localhost:3000/posts
• To update a post: PUT http://localhost:3000/posts/1
• To delete a post: DELETE http://localhost:3000/posts/1

You can use any REST client (like Postman) or your front-end application to interact with the fake JSON server.

2. Set Up GraphQL Server Using Apollo Server

To convert your JSON API to a GraphQL API, you'll use Apollo Server. Follow these steps:

• Install Apollo Server and GraphQL: npm install apollo-server graphql axios.

• Create a graphql-server.js file:
  

Run the GraphQL server: node graphql-server.js.

Testing the GraphQL Server

With your GraphQL server running, you can test it using GraphQL Playground (which Apollo Server provides by default) or using tools like Postman, Insomnia, or cURL.

• Open GraphQL Playground: Navigate to the URL provided by Apollo Server (typically http://localhost:4000).
• Run Queries: To get all posts:
