Hey everyone 👋🏻,

In this article, let us see how we can build an Exercise Planner Application using React.js.

✏ Demo for the Project & Initial Setup

So the first thing you need to do is to create a new project.
Make sure to install Node.js onto your system because we will be needing that for our project.

We will be using this tool for creating a new React Project :

Create React App :

Install Node.js :

Create a new React Project

// To create a new React Project 
npx create-react-app <project_name>
cd <project_name>
// To run the project 
npm start

Install React Router DOM package

npm install react-router-dom

Enter fullscreen modeExit fullscreen mode

Install JSON-server package globally

We will be using JSON-server for our project.

npm install json-server -g

Enter fullscreen modeExit fullscreen mode

Create a new file - exercises.json

This is the file that will contain all the exercises that we will be needing in this application. This file will serve as a local JSON store for our application.

store/data.json

{
  "exercises": [
    {
      "title": "Pushups",
      "details": "Pushups are beneficial for building upper body strength. They work the triceps, pectoral muscles, and shoulders. When done with proper form, they can also strengthen the lower back and core by engaging (pulling in) the abdominal muscles",
      "complete": false,
      "id": 119
    }
  ]
}

Enter fullscreen modeExit fullscreen mode

Inside a new terminal, run the json-server by running the command

json-server -g ./src/store/data.json --watch --port=3111
