Step 1: Add homepage to package.json

Create React App uses the homepage field to determine the root URL in the built HTML file.

"homepage": "https://myusername.github.io/my-app",

To publish it at https://myusername.github.io/my-app, run:

npm install --save gh-pages

Add the following scripts in your package.json:

"scripts": {
