How to deploy a create-react-app to a web host (ex. Siteground)?

Per the create-react-app docs, you run npm run build and basically just take the output and FTP it to your web server.

However your question is very broad -- you could automate through GitHub or some other tool, but that's really going to beg opinionated responses on StackOverflow (which isn't the right forum for those kinds of questions).

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.

npm run build creates a build directory with a production build of your app. Set up your favorite HTTP server so that a visitor to your site is served index.html, and requests to static paths like /static/js/main.<hash>.js are served with the contents of the /static/js/main.<hash>.js file.

I just uploaded my create-react-app to siteground with FileZilla here is the step by step:

1. Once you have it all production ready npm run build
2. Open siteGround on your browser and into myAcount section click on go to cPanel scroll down and find FTP Accounts
3. create a new account pointing to the directory public_html
4. once created, it will appear down below and all the way to the right click on configure FTP client and under manual setting you've got what you need to connnect
5. open FileZilla and in file go to siteManager then new site
6. host(in filezilla) === FTP server (in sitiGround), port set it as siteground port , protocol and encryption leave it as default
7. Logon Type set as normal , user === FTP user(siteGround) and password the one you've used to create that FTP user
8. click on connect and paste the content of yourApp/build (from the left side that is your PC) to (the folder at the right hand side) that is your public_html in siteGround

That's it! go to your website and check, the react app should be displayed there
