To deploy your frontend on GitHub Pages, follow these steps:

Make sure you have a GitHub repository for your project. Create a new branch in your repository, for example, gh-pages. Push your frontend code to the gh-pages branch. Go to your repository settings on GitHub. Click on "Pages" in the "Code and automation" section of the sidebar. Under "Build and deployment", select "Deploy from a branch". Choose the gh-pages branch as your publishing source. Optionally, select a folder for your publishing source, for example, / (root) or /docs. Click "Save". That's it! Your frontend should now be deployed on GitHub Pages. You can access your site at https://your-username.github.io/your-repo-name.
