Create your own Exercise Planner using React.js [Complete Code]

Hey everyone πŸ‘‹πŸ»,

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 :

image

Install Node.js :image

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 

Install JSON-server package globally

We will be using JSON-server for our project.

npm install json-server -g

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
    }
  ]
}

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

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

Learn React with one BIG Project [NOTES included] – Demo and Video Link

Hey everyone ,

I created a full fledged video to help others in learning React with ease.

The video includes :

1. Whiteboard Explanations for every concept that we use in the video.

2. NOTES will be also be given for future reference and I believe short notes help in recalling the concepts easily because they are short and to the point. Isn’t it ?

3. CRUD features (every app that you see out there uses CRUD at its core apart from other features that they contain)

Here is a quick demo that can help you decide whether you should watch the video or not :
