Calculator

Calculator React App that implements the concept of React with Redux. Click here for preview.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

You’ll need to have Node >= 6 on your machine and a modern web browser.

Installing

First install Node. After installation check the version of npm (run the following command in the terminal):

npm -v

If you have npm 5.2.0+ installed, you may use npx:

npx create-react-app calculator

cd calculator

else run the command :

npm install -g create-react-app

create-react-app calculator

cd calculator

Create React App is the best way to start building a new React single page application. It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production. Create React App doesn’t handle backend logic or databases; it just creates a frontend build pipeline, so you can use it with any backend you want. It uses build tools like Babel and webpack under the hood, but works with zero configuration.

Now install two more packages react-redux and redux:

npm install react-redux

npm install redux

After installation replace the src and public directories of the calculator app just created with the src and public directories of this repository that you have cloned on your personal machine.

That's all run the following command and enjoy!

npm start

Folder Structure

After creation, your project should look like this:

calculator/
  README.md
  node_modules
  LICENSE
  package.json
  CONTRIBUTING.md
  public/
    index.html
    favicon.ico
    manifest.json

    actionCreators/
      actionCreator.js

      index.css
    reducers/
      reducer.js
    validations/ 
      validator.js
    index.js 
    createServiceWorker.js

For the project to build, these files must exist with exact filenames:

• public/index.html is the page template;
• src/index.js is the JavaScript entry point.

You can delete or rename the other files.

You may create subdirectories inside src. For faster rebuilds, only files inside src are processed by Webpack.

Only files inside public can be used from public/index.html.

You can, however, create more top-level directories.

Built With

• ReactJS - JavaScript library used for UI
• Redux - For state management
• ECMASCRIPT 6 - Standard used to write Javascript code
• Babel - Transpiler used
