How Install React with Yarn? Use npm

React App Setup Guide

Create React App is an officially supported way to create single-page React applications. It offers a modern build setup with no configuration.

To install React:

With Yarn: yarn add react react-dom
With npm: npm install --save react react-dom

Setting up a New React App

When you create a new app, use npm or Yarn to install dependencies, depending on your tool to run create-react-app.

bash

npx create-react-app my-app

yarn create react-app my-app

Using Yarn in React Projects

Yarn installation is foundational for Yarn and React integration, as Yarn builds upon npm. Utilizing Yarn in React projects enhances dependency management efficiency and reliability compared to npm.

Tutorial Steps

Install create-react-app globally
Create a new React app project
Use Yarn to manage dependencies

First, install create-react-app globally:
bash
yarn global add create-react-app

Then create a new React app:
bash
yarn create react-app my-app

Managing React Packages with Yarn

How to install React packages using yarn?

To install Yarn globally:
bash
npm install -g yarn

Create a new React project with:
bash
yarn create react-app my-app

To add dependencies:

yarn add package-name
yarn add [email protected]
yarn add package-name@tag

When you run yarn, it creates yarn.lock tracking exact package versions installed. Add this file to version control for consistency across environments.

Additional Information

Yarn is faster, more secure, and more reliable than npm. It executes install tasks in parallel, increasing speed, and fully caches packages for offline installs.

The equivalent of npm install is:
bash
yarn

Identify why a package is installed:
bash
yarn why package-name

Note: Use Ctrl+C to stop Yarn installation issues.
