In this tutorial you will learn to install and create React Application on a Ubuntu Linux system.
You must have a running Ubuntu 20.04 system with console access.
Step 1 – Install Node.js
Node.js is required to create and run a React.js application. The following steps will install Node.js 14 on your Ubuntu system.
- Add the Node.js 14 (current stable version) PPA to your Ubuntu system
curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -
- Next, run the following command to install the Node.js to your system:
sudo apt install nodejs -y
- Finally, check the current active version of Node.js
- Also install
Yarnpackage manager on your system.
npm install -g yarn
Step 2 – Create A New React Application
You can create a React.js application using one of the following commands.
yarn create react-app myreactapp
Except yarn, you can also use npx (
npx create-react-app myreactapp) or npm (
npm init react-app myreactapp) commands to create React.js application.
On successful application creation, you will see a long result on screen. At the end, you will find the result like below with some useful commands.
Step 3 – Start React Application
Once you have created your React application. This will create a folder in current directory with project name. Switch to that project and run
yarn start to start application.
You can now view
myreactapp in the browser.
On Your Network: http://192.168.10.200:3000
Note that the development build is not optimized.
To create a production build, use yarn build.
The default react application start on port 3000. Access your React application using 3000 port with system IP address. For local machine use “localhost” followed by port.
Lets create an awesome user interface with React.
Step 4 – Create React.js Production Build
Once your application is ready for production deployment. Let’s create a production build of your React application. The Production build contains static files required to run application on production environment. You don’t need to install Node.js on production servers as they don’t contains any development files.
yarn build or
npm run build command to create production build of your React.js application.
On successful build, you will see the output like below:
yarn run v1.22.10 $ react-scripts build Creating an optimized production build... Compiled successfully. File sizes after gzip: 41.33 KB build/static/js/2.fefeb60f.chunk.js 1.59 KB build/static/js/3.63acee40.chunk.js 1.17 KB build/static/js/runtime-main.3da20c7a.js 591 B build/static/js/main.3ee865b4.chunk.js 531 B build/static/css/main.8c8b27cf.chunk.css The project was built assuming it is hosted at /. You can control this with the homepage field in your package.json. The build folder is ready to be deployed. You may serve it with a static server: yarn global add serve serve -s build Find out more about deployment here: https://cra.link/deployment Done in 26.59s.
All the production files are created under the build directory. Upload all the content from build directory to production website document root.
In case of any issue occurred on production server. First, you need to fix issue on local source code, then re-create the production build and re-deploy on server.
In this tutorial, you have learned, how to setup React.js development environment and access application in web browser. Additionally, you found instructions to create production build of your React application.
