Let's suppose you are using create-react-app and react-router v4+.
  1. Define App Homepage
  2. Set Basename & Route Path
  3. Update the Links
1. Define App Homepage:

In package.json add homepage like below

{ "name": "React App", "version": "0.1.0", "private": true, "homepage": "https://domain-name.com/directory-name", "dependencies": { "@testing-library/jest-dom": "^4.2.4", "@testing-library/react": "^9.5.0", "@testing-library/user-event": "^7.2.1", "react": "^16.13.1", "react-dom": "^16.13.1", "react-scripts": "3.4.1", "react-helmet": "^5.2.1", "react-router-dom": "^5.1.2", "axios": "^0.19.0" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" }, "eslintConfig": { "extends": "react-app" }, "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] } }
2. Set Basename & Route Path:
<Router basename={'/directory-name'}> <Route path={`${process.env.PUBLIC_URL}/`} component={HomePage} /> <Route path={`${process.env.PUBLIC_URL}/about.html`} component={AboutPage} /> <Route path={`${process.env.PUBLIC_URL}/contact.html`} component={ContactPage} /> <Route path={`${process.env.PUBLIC_URL}/blog.html`} component={BlogPage} /> </Router>
3. Update the Links:

In your code update urls of all the links/href etc.

<Link to={`${process.env.PUBLIC_URL}/about.html`}>About us</Link> <Link to={`${process.env.PUBLIC_URL}/contact.html`}>Contact us</Link> <Link to={`${process.env.PUBLIC_URL}/blog.html`}>My Blog</Link>

In public/index.html file set the PUBLIC_URL

<link rel="manifest" href="%PUBLIC_URL%/manifest.json" /> <link rel="stylesheet" href="%PUBLIC_URL%/style.css" />

Now, make new build using command - npm run build

After this, deploy build to the sub-directory from where you want to run react app, Enjoy!
