This package includes scripts and configuration used by Create React App.
- Getting Started – How to create a new app.
- User Guide – How to develop apps bootstrapped with Create React App.
npm install -g create-react-app create-react-app my-app --scripts-version=@fancyguy/react-scripts cd my-app/ npm start
Then open http://localhost:3000/ to see your app.
When you’re ready to deploy to production, create a minified bundle with
npm run build.
Get Started Immediately
You don’t need to install or configure tools like Webpack or Babel.
They are preconfigured and hidden so that you can focus on the code.
Just create a project, and you’re good to go.
Install it once globally:
npm install -g create-react-app
You’ll need to have Node >= 4 on your machine.
We strongly recommend to use Node >= 6 and npm >= 3 for faster installation speed and better disk usage. You can use nvm to easily switch Node versions between different projects.
This tool doesn’t assume a Node backend. The Node installation is only required for Create React App itself.
Creating an App
To create a new app, run:
create-react-app my-app --scripts-version=@fancyguy/react-scripts cd my-app
It will create a directory called
my-app inside the current folder.
Inside that directory, it will generate the initial project structure and install the transitive dependencies:
my-app/ README.md node_modules/ package.json .gitignore public/ favicon.ico index.html src/ App.css App.js App.test.js index.css index.js logo.svg
No configuration or complicated folder structures, just the files you need to build your app.
Once the installation is done, you can run some commands inside the project folder:
npm start or
Runs the app in development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will see the build errors and lint warnings in the console.
npm test or
Runs the test watcher in an interactive mode.
By default, runs tests related to files changed since the last commit.
npm run build or
Builds the app for production to the
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
