In this blog post, we'll walk through the process of setting up and starting a new React app from scratch. Whether you're a beginner or an experienced developer, this step-by-step guide will provide you with the information you need to get started with your first React app project. We'll cover topics like installing the necessary tools, creating a new project, and adding features and components to your app. By the end of this post, you'll have a solid foundation for building your own React app and you'll be ready to take your skills to the next level.
-
Install Node.js: React is built using JavaScript, so you'll need to have Node.js installed on your computer to run React apps. You can download and install Node.js from the official website or using a package manager like Homebrew (for macOS) or Chocolatey (for Windows).
-
Install the React CLI: The React command-line interface (CLI) is a tool that allows you to create and manage React projects. To install the React CLI, open a terminal and run the following command:
npm install -g react-cli
- Create a new project: Once you have the React CLI installed, you can create a new React project by running the following command:
This will create a new directory called "my-app" with the basic structure and files needed for a React app.
- Install dependencies: Navigate to the project directory and run the following command to install the required dependencies:
npm install
- Start the development server: Once the dependencies have been installed, you can start the development server by running the following command:
npm start
This will start the development server and open a new browser window with your React app. Any changes you make to the code will be automatically reflected in the browser.
- Go to the folder
- Open the terminal in that folder
- Run these commands
npm init react-app my-app
cd my-app
npm start
