What is CRA and what are its benefits? in REACT

Practice



The

create-react-app
CLI tool lets you quickly create and run React applications with no configuration step.

Let's create a Todo application using CRA :

# Installation
$ npm install -g create-react-app

# Create new project
$ create-react-app todo-app
$ cd todo-app

# Build, test and run
$ npm run build
$ npm run test
$ npm start

It includes everything we need to build a React application:

  1. Support for React, JSX, ES6 and Flow syntax.
  2. Language extras beyond ES6, such as the object spread operator.
  3. Autoprefixed CSS, so you don't need -webkit- or other prefixes.
  4. A fast interactive test runner with built-in support for coverage reports.
  5. A live development server that warns about common mistakes.
  6. A build script that bundles JS, CSS and images for production, with hashes and source maps.
