JSON Server is a simple project that helps you to setup a REST API with CRUD operations very fast. So let's learn how we can create fake rest api using json-server, It is useful for building frontend apps and for testing integration components.
Step-1:
Download node js, refer below link:
https://nodejs.org/en/download/
Open a command prompt (or PowerShell), and enter the following:
node –v
The system should display the Node.js version installed on your system. You can do the same for NPM:
npm –v
For above two commands you should get response as below :
C:\Users>node -v
v10.16.3
C:\Users>npm -v
6.9.0
Step:2
npm install -g json-server

Step-3
Create a json file as db.json and open cmd in that path
Define the json format:
{
"employees": [
{
"id": 1,
"first_name": "sidharth",
"last_name": "shukla",
"email": "sidharth@automationreinvented.com"
},
{
"id": 2,
"first_name": "Steve",
"last_name": "smith",
"email": "steve@automationreinvented.com"
},
{
"id": 3,
"first_name": "virat",
"last_name": "kohli",
"email": "virat@automationreinvented.com"
}
]
}
Step-04:
Run the below command from command prompt
json-server --watch db.json
Step-05:
By Default it will take localhost:3000, Now we can open URL http://localhost:3000/employees in the browser

Step-06:
How to test in Postman?
Just open postman tool and ru below URI:
It's possible to extend URLs with further parameter. E.g. you can apply filtering by using URL parameters like you can see in the following:
http://localhost:3000/employees?last_name=shukla
http://localhost:3000/employees?first_name=sidharth
http://localhost:3000/employees/1
Validate the status code and response body.

Step-07:
The following HTTP endpoints are created automatically by JSON server:
GET /employees
GET /employees/{id}
POST /employees
PUT /employees/{id}
PATCH /employees/{id}
So all the above methods can be tested both from Postman or Rest Assured.
