Create React App one can configure your own webpack and babel setups as it’s one of the excellent tools for React developers.

1. How Create React App help in creating a New
React Applications?

2. React is one of the popular JavaScript frameworks that help in
creating front-end applications. React was created by Facebook and
gained massive popularity. It allows developers to create a fast app
using an intuitive programming paradigm. It ties JavaScript with an
HTML like syntax known as JSX.
Previously starting a new React project would have a complicated
multi-step process that involves setting a system. This code
transpiler converts modern syntax to code that is readable by all
browsers. Create React Apps which cover all JavaScript packages you
need to run a React node JS project.

3. The project makes add code transpiring, basic linting, testing, and
building systems. You can add a server with hot reloading which will
refresh your page with making appropriate changes. Create
directories structures and components from where you can jump and
start coding within a few minutes.
Moreover, you needn’t worry about configuring a build system. You
don’t need to transpile code to cross-browser. You don’t have to
worry about the most complicated system. Just start writing React
code with minimal preparation.

4. Building a react app is quite tough at the beginning. It mainly uses
dependencies, configuration, and other requirements before you
create an app react app. React app uses the CTI tool, which helps in
reducing all complexities and makes react apps simple to
understand. The create react apps tool is best for beginners as it set
up a development environment quickly with providing excellent
developers experience and optimizes the app for the production.
Check the requirements
As create React, apps are maintained by Facebook; it can work on
any platforms. Example: Windows, Linux, macOS, etc. create react
project where you need to install the following things like:

5. ● Node version >= 8.10
● NPM version >= 5.6
Know how to check the current version of node and npm in the
system by running code:
$node -v
Check npm version in the command prompt
$ npm -v
Know how to install
If you want to learn how to install react using CRA tool, know the
steps below

6. Install React
● C:Usersjavatpoint> npm install -g create-react-app
Create a new React Project
● C:Usersjavatpoint> create-react-app react project
● C:Usersjavatpoint> npx create-react-app react project
The above command will help to install the react and create a new
project with the same name. Type command is given below:

7. What comes with create-react-app?
Here, we can add more support for things like Sass or TypeScript. It
can run with a single command and get new react apps which comes
along with:
● A recommended starting folder structure
● Extensibility
● Solid build setup with webpack and Babel
● Script to run our React Application

8. What’s a default way we can start with?
1. Build Setup
Our react app needs to build a step to transpile and code something
that browsers can read. With this, we can see many setups without
using Create App React.
● Add convenient folder structure
If you want to know about files and folders available in the root
directory then check below:

9. ● Node_modules: It comes with react library and other third-
party libraries
● Public: It holds public asset of application which contain
index.html which mount the application on <div id=” root”>
</div>element.
● Src: It contains App.css, index.css, App.js, and serviceworker.js
files. The App.js file is mainly responsible for displaying the
output screen to React.
● Package-lock.json: It helps in generating automatically
operations where npm package modifies node_modules and
cannot be published.
● Package.json: It holds metadata which gives information to
npm and allows to identify project and handle dependencies.
● README.md: It helps in the product documentation for how to
read about react topics

10. 2. Build Scripts
Create React App, which comes with few scripts that help in
development. Use scripts whenever we want to:
● Run application script for Development
● Build applications for production
● A test application that creates tests
● Add below code in package.json

11. Now run above commands like shown below:
● Start: Here, the command will start a development application.
You can open the application in the browser
● Build: One can bundle a production application and generate
only a few files that can host users.
● Test: Run test which comes with Create App React
● Eject: The eject gives access to the configure aspect for React
application. Create React App with no longer handling the
configuration for your application.

12. 3. Add scripts to run applications
Take a look at what’s running tests look like:
4. Add Scripts to bundle for production
For hosting the code for users, we need to bundle all code into a
JavaScript file that users can use for loading. You can run the
following files as coded below:
npm run build
After successfully creating the new files, we need to provide the
React app to our users. You can add new files to the build folder.
Now host on a server and point users towards index.html file.

13. Wrapping up:
With Create React App one can configure own webpack and babel
setups as it’s one of the excellent tools for React developers. Now
again use React App to start your applications which provide a solid
base and keep info updated by the React team.
