Change The Default Port Number Of JSON-Server

In my previous blog we have seen how to create a REST API with JSON Server, if you missed please have a look at here Link

And whenever we start the JSON Server it is running on http://localhost:3000, mean its running in your localhost and the port number is 3000, In this blog we will see how to change the port number from 3000 to another port (xxxx) incase something you are running already on 3000

Please refer here how to setup the JSON Server on your machine - Link

Once we are done with the setup and if you want to start the JSON Server in different port then we have to run this command in terminal to start the JSON Server

Usually we use this command to start JSON Server which will run the server on 3000 port

json-server data.json


  • Start the JSON Server in different port

Instead of running the above command we have additionally pass the port parameter value to start in particular port as per your need

json-server -p 4000 data.json

And now you can open the URL in browser or Postman to check the server is connected and its up and running 



And you can monitor your server logs as well on the terminal


  • **Important - Do not close the server which we started from terminal until you preformed all actions, if you close the server the endpoints will not work further, and you can start the server again by following the same steps

In the following will learn how to setup JSON Server and publish a sample REST API Most of the time we will not get the flexible dummy REST API end points to practice or learn to validate the CRUD operations, we have an option to create full fake REST API with zero coding Reference Installing JSON Server JSON Server is available as a NPM package, The installation can be done by using the Node.js package manager, since we are going to use NPM packages we required Node.js to be installed before moving further Install Node.js - download the Node.js and install as per your system requirements (Download Node.js here)  and confirm the Node.js is installed successfully on your system as per following the steps shown below  Install JSON Server - We will install JSON Server now using the NPM package, run the below in command prompt    npm install json-server (or) npm install -g json-server **  by adding -g option we make sure the package is installed globally on our system   JSON File - N

  Shift-Left Development Process   What is shift-left? Shift Left is a practice intended to find and prevent defects early in the software delivery process. The idea is to improve quality by moving tasks to the left as early as the lifecycle. Shift Left testing means testing earlier in the software development process. “Start Testing activities as early as possible in the development life cycle. Test Early and Often” How does it differ from our traditional model? A typical waterfall software development project would have seen testing occur immediately prior to release into production. This meant that when bugs or usability issues were inevitably found, the release would be delayed until these were fixed. Why Shift Left? In the traditional software development model, requirements are kept on the left side of the plan, and the delivery and testing requirements are on the right. The problem is that these practices can’t handle changing expectations and requirements, resulting in negativ
