Getting started with GitHub Pages for beginners | Tutorial

Key Concepts

• GitHub Pages: A static site hosting service that takes files directly from a GitHub repository and hosts them as a live website.
• Static Website: A site consisting of fixed files (HTML, CSS, JavaScript) that do not require server-side processing.
• GitHub Actions: An automation platform used to build, test, and deploy code; in this context, it automates the build process for frameworks like Next.js.
• DNS (Domain Name System): The system used to map a custom domain name to the IP address of the hosting server.
• SSL Certificate: A digital certificate that provides authentication for a website and enables an encrypted connection (HTTPS).

Overview of GitHub Pages

GitHub Pages provides free, secure hosting for static websites directly from a GitHub repository. It is an ideal solution for developer portfolios, documentation, or simple web projects. A critical security note provided is that even if the source repository is private, the published website will be public.

Deployment Methodologies

There are two primary ways to deploy a site to GitHub Pages via the repository Settings > Pages menu:

1. Deploy from a Branch

This is the simplest method for basic static sites.

• Process: Navigate to the "Build and deployment" section, select the source branch (e.g., main), and click "Save."
• Use Case: Best for simple HTML/CSS projects that do not require complex build steps.

2. GitHub Actions Workflow

This method is recommended for modern frameworks that require a build process.

• Process:
  1. Select "GitHub Actions" as the source.
  2. Browse the suggested workflows (e.g., Next.js, Jekyll, Astro, Hugo, Gatsby, or static HTML).
  3. Select the appropriate configuration file and commit it to the repository.
  4. The commit triggers an automated "Action run," which can be monitored in the Actions tab.
• Benefit: This automates the build and deployment pipeline, ensuring the site is updated whenever code is pushed.

Custom Domains and Security

Once a site is live at the default URL (username.github.io/repository-name), users can configure a custom domain:

• Configuration: In the "Custom domain" section of the Pages settings, enter the desired domain (e.g., yourwebsite.com).
• DNS Setup: Users must configure DNS records with their domain provider to point to GitHub’s servers. A green check mark in the settings indicates a successful DNS verification.
• HTTPS Enforcement: After domain verification, users should check the "Enforce HTTPS" box. This triggers the generation of a free SSL certificate, ensuring the site is secure and displays the padlock icon in browsers.

Summary of Workflow

1. Preparation: Ensure the project is a static website hosted in a GitHub repository.
2. Activation: Enable Pages in the repository settings using either a branch or an Actions workflow.
3. Deployment: Monitor the build process via the Actions tab.
4. Customization: Optionally link a custom domain and enable HTTPS for security.

Conclusion

GitHub Pages offers a streamlined, free, and professional hosting environment for developers. By leveraging either direct branch deployment or automated GitHub Actions, users can move from code to a live, secure, and custom-branded website with minimal configuration.
