How to Host JSON Server

Hello Dev, if you’re looking to host a JSON server, you’re in the right place! JSON, or JavaScript Object Notation, is a lightweight data exchange format that is easy for humans to read and write. It is widely used in web applications to transmit data between the server and the client. In this article, we’ll guide you through the process of hosting your own JSON server, step by step.

Prerequisites

Before we get started, let’s make sure we have everything we need:

Item	Description
Node.js	JavaScript runtime environment
npm	Node package manager
JSON server	Command line tool for creating JSON APIs

If you don’t have Node.js and npm installed, you can download and install them from the official website. To install JSON server, open your terminal or command prompt and run:

npm install -g json-server

Create a JSON file

The first step in hosting a JSON server is to create a JSON file that contains the data you want to serve. You can do this by hand or by using a tool like Postman or Insomnia to create a sample request and response. Make sure your JSON file follows the correct format, with curly braces {} enclosing key-value pairs separated by colons :

{"employees": [{"id": 1,"name": "John Doe","email": "john.doe@example.com"},{"id": 2,"name": "Jane Smith","email": "jane.smith@example.com"}]}

Start the server

Once you have your JSON file ready, you can start the JSON server by running the following command in your terminal:

json-server --watch db.json

This will start the server on port 3000 by default and watch the JSON file for changes. You can access the server by visiting http://localhost:3000 in your web browser.

Customize server settings

If you want to customize the server settings, you can do so by passing options to the json-server command. For example, you can change the port number by using the –port option:

json-server --watch db.json --port 4000

You can also add custom routes, middleware, and other features using the json-server API. For more information, check out the official documentation.
