Create React App

Create React apps with no build configuration.

• Creating an App – How to create a new app.
• User Guide – How to develop apps bootstrapped with Create React App.

Create React App works on macOS, Windows, and Linux.
If something doesn’t work, please file an issue.
If you have questions or need help, please ask in GitHub Discussions.

Quick Overview

npx create-react-app my-app
cd my-app
npm start

If you’ve previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app or yarn global remove create-react-app to ensure that npx always uses the latest version.

(npx comes with npm 5.2+ and higher, see instructions for older npm versions)

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.

Create a project, and you’re good to go.

Creating an App

You’ll need to have Node 14.0.0 or later version on your local development machine (but it’s not required on the server). We recommend using the latest LTS version. You can use nvm (macOS/Linux) or nvm-windows to switch Node versions between different projects.

To create a new app, you may choose one of the following methods:

npx

npx create-react-app my-app

(npx is a package runner tool that comes with npm 5.2+ and higher, see instructions for older npm versions)

npm

npm init react-app my-app

npm init <initializer> is available in npm 6+

Yarn

yarn create react-app my-app

yarn create <starter-kit-package> is available in Yarn 0.25+

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
│   └── manifest.json
└── src
    ├── App.css
    ├── App.js
    ├── App.test.js
    ├── index.css
    ├── index.js
    ├── logo.svg
    └── serviceWorker.js
    └── setupTests.js

No configuration or complicated folder structures, only the files you need to build your app.
Once the installation is done, you can open your project folder:

Inside the newly created project, you can run some built-in commands:

npm start or yarn start

Runs the app in development mode.
Open http://localhost:3000 to view it in the browser.

The page will automatically reload if you make changes to the code.
You will see the build errors and lint warnings in the console.

npm test or yarn test

Runs the test watcher in an interactive mode.
By default, runs tests related to files changed since the last commit.

Read more about testing.

npm run build or yarn build

Builds the app for production to the build folder.
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.

User Guide

You can find detailed instructions on using Create React App and many tips in its documentation.

How to Update to New Versions?

Please refer to the User Guide for this and other information.

Philosophy

• One Dependency: There is only one build dependency. It uses webpack, Babel, ESLint, and other amazing projects, but provides a cohesive curated experience on top of them.

• No Configuration Required: You don’t need to configure anything. A reasonably good configuration of both development and production builds is handled for you so you can focus on writing code.

• No Lock-In: You can “eject” to a custom setup at any time. Run a single command, and all the configuration and build dependencies will be moved directly into your project, so you can pick up right where you left off.

What’s Included?

Your environment will have everything you need to build a modern single-page React app:

• React, JSX, ES6, TypeScript and Flow syntax support.
• Language extras beyond ES6 like the object spread operator.
• Autoprefixed CSS, so you don’t need -webkit- or other prefixes.
• A fast interactive unit test runner with built-in support for coverage reporting.
• A live development server that warns about common mistakes.
• A build script to bundle JS, CSS, and images for production, with hashes and sourcemaps.
• An offline-first service worker and a web app manifest, meeting all the Progressive Web App criteria. (Note: Using the service worker is opt-in as of react-scripts@2.0.0 and higher)
• Hassle-free updates for the above tools with a single dependency.

Check out this guide for an overview of how these tools fit together.

The tradeoff is that these tools are preconfigured to work in a specific way. If your project needs more customization, you can «eject» and customize it, but then you will need to maintain this configuration.

Popular Alternatives

Create React App is a great fit for:

• Learning React in a comfortable and feature-rich development environment.
• Starting new single-page React applications.
• Creating examples with React for your libraries and components.

Here are a few common cases where you might want to try something else:

• If you want to try React without hundreds of transitive build tool dependencies, consider using a single HTML file or an online sandbox instead.

• If you need to integrate React code with a server-side template framework like Rails, Django or Symfony, or if you’re not building a single-page app, consider using nwb, or Neutrino which are more flexible. For Rails specifically, you can use Rails Webpacker. For Symfony, try Symfony’s webpack Encore.

• If you need to publish a React component, nwb can also do this, as well as Neutrino’s react-components preset.

• If you want to do server rendering with React and Node.js, check out Next.js or Razzle. Create React App is agnostic of the backend, and only produces static HTML/JS/CSS bundles.

• If your website is mostly static (for example, a portfolio or a blog), consider using Gatsby or Next.js. Unlike Create React App, Gatsby pre-renders the website into HTML at build time. Next.js supports both server rendering and pre-rendering.

• Finally, if you need more customization, check out Neutrino and its React preset.

All of the above tools can work with little to no configuration.

If you prefer configuring the build yourself, follow this guide.

v5.0.0 (2021-12-14)

Create React App 5.0 is a major release with several new features and the latest version of all major dependencies.

Thanks to all the maintainers and contributors who worked so hard on this release! 🙌

Highlights

• webpack 5 (#11201)
• Jest 27 (#11338)
• ESLint 8 (#11375)
• PostCSS 8 (#11121)
• Fast Refresh improvements and bug fixes (#11105)
• Support for Tailwind (#11717)
• Improved package manager detection (#11322)
• Unpinned all dependencies for better compatibility with other tools (#11474)
• Dropped support for Node 10 and 12

Migrating from 4.0.x to 5.0.0

Inside any created project that has not been ejected, run:

npm install --save --save-exact react-scripts@5.0.0

or

yarn add --exact react-scripts@5.0.0

NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running npm install (or yarn) if you encounter errors after upgrading.

If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.

Breaking Changes

Like any major release, react-scripts@5.0.0 contains a number of breaking changes. We expect that they won’t affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.

Dropped support for Node 10 and 12

Node 10 reached End-of-Life in April 2021 and Node 12 will be End-of-Life in April 2022. Going forward we will only support the latest LTS release of Node.js.

4.0.0 (2020-10-23)

Create React App 4.0 is a major release with several new features, including support for Fast Refresh!

Thanks to all the maintainers and contributors who worked so hard on this release! 🙌

Highlights

• Fast Refresh #8582
• React 17 support
  • New JSX transform #9645
• TypeScript 4 support #9734
• ESLint 7 #8978
  • New Jest and React Testing Library rules #8963
• Jest 26 #8955
• PWA/workbox improvements
  • Switch to the Workbox InjectManifest plugin #9205
  • Now its own template so it can be released independently
• Web Vitals support #9116

Migrating from 3.4.x to 4.0.0

Inside any created project that has not been ejected, run:

npm install --save --save-exact react-scripts@4.0.0

or

yarn add --exact react-scripts@4.0.0

NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running yarn (or npm install) if you encounter errors after upgrading.

If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.

Breaking Changes

Like any major release, react-scripts@4.0.0 contains a number of breaking changes. We expect that they won’t affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.

ESLint

We’ve upgraded to ESLint 7 and added many new rules including some for Jest and React Testing Library as well as the import/no-anonymous-default-export rule. We’ve also upgraded eslint-plugin-hooks to version 4.0.0 and removed the EXTEND_ESLINT flag as it is no longer required to customize the ESLint config.

Jest

We’ve upgraded to Jest 26 and now set resetMocks to true by default in the Jest config.

Service workers

We’ve switched to the Workbox InjectManifest plugin and moved the PWA templates into their own repository.

Removed typescript flag and NODE_PATH support

We’ve removed the deprecated typescript flag when creating a new app. Use --template typescript instead. We’ve also dropped deprecated NODE_PATH flag as this has been replaced by setting the base path in jsconfig.json.

Fix dotenv file loading order

We’ve changed the loading order of env files to match the dotenv specification. See #9037 for more details.

Dropped Node 8 support

Node 8 reached End-of-Life at the end of 2019 and is no longer supported.

3.0.0 (April 22, 2019)

Create React App 3.0 brings some exciting new features including support for Hooks!

Thanks to all the maintainers and contributors who worked so hard on this release! 🎉

Highlights

• Jest 24: #6278
• Hooks support: #5997
• TypeScript linting: #6513
• browserslist support in @babel/preset-env: #6608
• Absolute imports using jsconfig.json/tsconfig.json: #6656

Migrating from 2.1.x to 3.0.0

Inside any created project that has not been ejected, run:

npm install --save --save-exact react-scripts@3.0.0

or

yarn add --exact react-scripts@3.0.0

If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.

Breaking Changes

Like any major release, react-scripts@3.0.0 contains a few breaking changes. We expect that they won’t affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.

Jest 24

We’ve updated from Jest 23 to get the latest improvements in Jest 24. We’ve noticed some differences in snapshot serialization in Jest 24, so you may need to adjust your tests slightly once you update. You can read more about what’s changed in the Jest 24 blog post.

Hooks support

We now enforce Rules of Hooks with eslint-plugin-react-hooks. If you are breaking any of the rules of Hooks this will cause your build to fail.

TypeScript linting

We now lint TypeScript files. You can see the list of rules we enforce to check if your project is compatible. If you’re using Visual Studio Code you can follow our guide to setup up your editor to display lint warnings.

browserslist support in @babel/preset-env

The browserslist config in your package.json is now used to control the output of your JavaScript files. You can use separate configuration for development and production. See here for a good starting point which gives a good development experience, especially when using language features such as async/await, but still provides high compatibility with many browsers in production

Remove —no-watch flag

We’ve removed the --no-watch flag from the start script in favor of Jest’s own --watchAll=false.

New structure in asset-manifest.json

All asset paths have been moved under the files key in asset-manifest.json.

New Features
using jsconfig.json/tsconfig.json

We now support setting baseUrl in jsconfig.json and tsconfig.json. To configure baseUrl to point to the src directory in your JavaScript project, create a jsconfig.json file in your project root:

```json
{
  "compilerOptions": {
    "baseUrl": "src"
  },
  "include": ["src"]
}
```

If you have a TypeScript project you can configure baseUrl the same way in your tsconfig.json.

Currently the only supported options for baseUrl are node_modules (the default) and src.

PostCSS Normalize

You can now include a version of Normalize.css in your project that will use your browserslist setting to generate the appropriate styles for your target browsers. To include it simply add @import-normalize at the top of one of your CSS files.

Migrating from 1.0.7 to 1.0.8

Inside any created project that has not been ejected, run:

npm install --save-dev --save-exact react-scripts@1.0.8

or

yarn add --dev --exact react-scripts@1.0.8

You may optionally then move react-scripts from devDependencies to dependencies since that’s how we’ll structure newly created projects. It is not necessary though.

If you previously used HTTPS=true environment variable in development, make sure you aren’t affected by a now-fixed vulnerability in Webpack by visiting this page. You can read more about the vulnerability here.

If you left the service worker integration enabled and didn’t change how it works, you can replace src/registerServiceWorker.js with this updated version.

If you haven’t changed the default CSS organization, you may want to apply this fix that makes index.css take precedence over App.css in your project.

Migrating from 1.0.0 to 1.0.1

Inside any created project that has not been ejected, run:

npm install --save-dev --save-exact react-scripts@1.0.1

or

yarn add --dev --exact react-scripts@1.0.1

1.0.0 (May 18, 2017)

We’ve been working on this release for the past few months, and there are many big impovements, from migrating to webpack 2 to a brand new runtime error overlay and built-in support for Progressive Web Apps.

So instead of just enumerating them here, we decided to write a blog post about all the new features.

Check it out: What’s New in Create React App.

Have you read it? Now let’s see how to update your app to the latest version.

Migrating from 0.9.5 to 1.0.0

First, ensure you are using the latest Node 6 LTS or newer. In 1.0.0, we have dropped support for Node 4 and NPM 2.

Inside any created project that has not been ejected, run:

npm install --save-dev --save-exact react-scripts@1.0.0

You may also optionally update the global command-line utility for bug fixes:

npm install -g create-react-app

Ensure application and test files reside in src/

We’ve never supported importing files from outside src/, nor have we supported running tests outside of src/.
We also never explicitly forbid doing so, which caused confusion when things didn’t work like they should.

When running or building your application, you may see a message like so:

You attempted to import ... which falls outside of the project src/ directory.

To remedy this, simply move any files that you import within src/ and update your relative imports accordingly. This enforces that files that import each other stay in src/, and other folders serve different purposes (e.g. the public/ folder just gets served from the root).

If you used relative imports outside the project directory as a way to share code with another project, consider using a monorepo instead, so that other projects are symlinked to your project’s node_modules/. Then you can import them as a Node modules.

While running npm test, you may notice some of your tests are missing. Please move any top-level test directory (i.e. __test__, __spec__) or files (i.e. *.test.js, *.spec.js) into src/. Conversely, if you have some similarly named files that you don’t want Jest to run, move them outside of src/.

Import required locales for Moment.js

Moment.js locales are now purposely excluded from the bundle unless explicitly depended on.

Please import the locales you need:

import moment from 'moment';
import 'moment/locale/fr';
import 'moment/locale/es';

You can no longer import file content

You can no longer import a file and expect to receive its contents as an encoded string.
This behavior was confusing and inconsistent depending on the file size.

Importing files with unknown extensions will now always include them into the build and return a valid URL.

If you’d like to import a file’s contents as a string, consider contributing to #1944.
For the time being, you must embed assets within an export:

// sample.txt
export default `i want
this data as a string
`;

You can then import this as so:

import sampleText from './sample.txt';

// ...

Confusing window globals can no longer be used without window qualifier

Please prefix any global method with window., you may experience this with methods such as confirm.

Simply update references from confirm to window.confirm.

Note that this new lint error will likely uncover legitimate accidental uses of global variables where you meant to define a local variable instead.

Why is my import erroring out?

You can no longer use AMD import syntax, nor define an import anywhere other than the top of the file.

This is to reduce confusion around import statements, which do not allow you to evaluate code between them.

I see many accessibility warnings

We have enabled a new set of rules to help make applications more accessible, please take time to learn about the errors and fix them.

You can search for every lint rule name in the right column and read its description on the web. The fixes are usually very simple.

I see many warnings about PropTypes and createClass

We have enabled the lint warnings about React APIs deprecated in React 15.5.
You can automatically convert your project to fix them by running the corresponding codemods.

How do I make my tests work with Jest 20?

Please refer to the Jest 19 and Jest 20 breaking changes for migration instructions.

If you use snapshots, you will likely need to update them once because of the change in format.

Flexbox 2009 spec is no longer polyfilled

The old, 2009 specification for Flexbox is deprecated and is 2.3x slower than the latest specification.

We are no longer polyfilling it automatically.

I see «Definition for rule ‘jsx-a11y/alt-text’ was not found (jsx-a11y/alt-text)» in the editor

Follow these steps if you see errors about missing lint rules in the editor.

1. Ensure that in your editor ESLint settings you have «Use Global ESLint» turned off
2. Run npm install in your project (or yarn)
3. Quit your editor completely (ensure its process doesn’t hang around)
4. Start the editor again

If you still have the problem please file an issue.

How to turn my app into a Progressive Web App?

After the regular update procedure above, add these line to <head> in public/index.html:

    <meta name="theme-color" content="#000000">
    <!--
      manifest.json provides metadata used when your web app is added to the
      homescreen on Android. See https://developers.google.com/web/fundamentals/engage-and-retain/web-app-manifest/
    -->
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json">

Then create a file called public/manifest.json that looks like this:

{
  "short_name": "React App",
  "name": "Create React App Sample",
  "icons": [
    {
      "src": "favicon.ico",
      "sizes": "192x192",
      "type": "image/png"
    }
  ],
  "start_url": "./index.html",
  "display": "standalone",
  "theme_color": "#000000",
  "background_color": "#ffffff"
}

Finally, create src/registerServiceWorker.js with this template, import it from src/index.js and call the function it exports.

Anything missing?

This was a large release, and we might have missed something.

Please file an issue and we will try to help.

Some of my tests started crashing because of unhandled rejections

Unhandled Promise rejections will now crash tests. You can fix them by explicitly catching the errors you don’t care about.
