Exploring go Hugo Framework for SSGPermalink

Hugo is a fast and flexible open-source static site generator written in Go, designed to help developers build modern websites quickly without relying on databases or heavy server-side frameworks. It uses simple Markdown files for content, supports powerful templating and theming systems, and can generate entire websites in milliseconds. With features like built-in live reload, content organization, internationalization, and Hugo Modules for reusable components, it’s ideal for blogs, documentation sites, portfolios, and even complex multi-language websites. Hugo integrates easily with platforms like GitHub Pages and Netlify, making it a popular choice for developers seeking performance, simplicity, and portability in their web projects.

Hugo Project Structure with Hugo ModulesPermalink

Assume you have a site for a project like Agones, and your directory looks like this:

agones/
├── site/   <- Your Hugo site root
│   ├── config.toml
│   ├── content/
│   ├── layouts/
│   ├── static/
│   ├── themes/   <- Can be empty if using Hugo Modules
│   └── go.mod    <- Created by `hugo mod init`
├── build/
├── cmd/
├── pkg/
└── README.md

After running:

cd agones/site
hugo mod init github.com/googleforgames/agones/site

You’ll get this inside site/go.mod:

module github.com/googleforgames/agones/site

go 1.20

What is purpose of cmd and pkg folder?Permalink

These are conventions in Go projects, not specific to Hugo, but useful when your Hugo site is part of a larger Go monorepo, like agones.

cmd/: Contains entry points (main packages) for Go binaries. Each subfolder usually builds to a separate binary. Example: cmd/controller/, cmd/allocator/

pkg/: Contains reusable Go packages that can be imported by cmd/ or other modules. Example: pkg/apis/, pkg/util/

🟡 Note: You typically don’t need these unless you’re doing Go development in parallel with the Hugo site (as in the case of Agones).

Should I run go build from site directory?Permalink

No, not for building the Hugo site.

go build is for building Go binaries — not for generating static websites.

✅ To build the Hugo site, run:

hugo
(from the site/ directory)

This will use config.toml and the content/, layouts/, static/ folders to generate the final website.

Where the build process the put the output?Permalink

By default, Hugo generates your static website into a folder named:

public/
So after running:

hugo
You’ll get:

site/
├── public/
│ ├── index.html
│ ├── css/
│ ├── js/
│ ├── …

You can change the output directory like this:

hugo -d ../build_output/

Can hugo website be published on github?Permalink

Yes! You can publish it on GitHub Pages:

Option A: GitHub Pages (User or Project)

Generate the site:

hugo
Push the contents of the public/ folder to the gh-pages branch (or main, if using GitHub Pages defaults).

In GitHub:

Go to Settings > Pages

Select source as gh-pages branch (or main), and directory as / (root)

🔗 Tip: You can use GitHub Actions to automate the deployment.

What needs to be done to publish the website on Netlify?Permalink

Netlify makes Hugo deployment very easy:

Steps:

• Push your Hugo site to a GitHub repo.
• Go to Netlify and:
  • Click “Add new site”
  • Choose “Import from GitHub”
  • Select your Hugo repo
• In build settings:
  • Build command: hugo
  • Publish directory: public
• Click Deploy site
• Netlify will:
  • Clone your repo
  • Run the build
  • Serve your site with HTTPS, CDN, and more

🎯 Bonus: You can set environment variables like HUGO_VERSION if needed.

How to manage different branch for publishing website?Permalink

When working on Hugo project like ‘Agones’ and I push my project into github then it will go into main branch. Should I push public folder also? How to make sure that content of a specific folder (public) go to gh-branch and nothing else.

Should you push the public/ folder to the main branch?Permalink

No, you should not push the public/ folder to the main branch.

main branch should only contain your Hugo source files (content, config, layouts, etc.)

The public/ folder is the generated output and should go to a separate branch, typically gh-pages, for GitHub Pages to serve.

How to push only the public/ folder to the gh-pages branch?Permalink

You can automate this with a few methods. Below is the most straightforward manual + scriptable approach:

Method 1: Manual (once or occasionally)
From your site/ directory (after running hugo):

Navigate to the public folder
cd public

Initialize a separate Git repo in public/
git init
git remote add origin https://github.com/your-username/[your-repo].git

Switch to the gh-pages branch
git checkout -b gh-pages

Commit and push the contents
git add .
git commit -m “Deploy site to GitHub Pages”
git push –force origin gh-pages

✅ This will push only the contents of public/ to gh-pages.

Method 2: Use a Deployment Script
You can automate it using a shell script like this:

Build the site
hugo

Go to public folder
cd public

Init a temporary repo
git init git remote add origin git@github.com:[your-username]/[your-repo].git git checkout -b gh-pages

Commit and force push git add .
git commit -m “Publishing to gh-pages”
git push –force origin gh-pages

Cleanup cd .. rm -rf public/.git Make sure it’s executable:

Create a script .github/workflows/deploy.yml

name: Deploy Hugo site to GitHub Pages

on:
  push:
    branches:
    - main  # Trigger on push to main branch

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout repo
    uses: actions/checkout@v3

    - name: Setup Hugo
    uses: peaceiris/actions-hugo@v2
    with:
    hugo-version: '0.125.4'  # Update to your required version

    - name: Build site
    run: hugo --minify

    - name: Deploy to GitHub Pages
    uses: peaceiris/actions-gh-pages@v3
    with:
    github_token: $
    publish_dir: ./public
    publish_branch: gh-pages

chmod +x deploy.sh

Then run:

./deploy.sh

🧩 Why Use Hugo Modules?Permalink

Instead of manually downloading or including themes and components, you can:

✅ Import a theme like this in config.toml:Permalink

[module]
  [[module.imports]]
    path = "github.com/theNewDynamic/gohugo-theme-ananke"

✅ Hugo will download the theme as a Go module:Permalink

hugo mod get

No more git submodules or manual copying! It’s clean, version-controlled, and reproducible.

🔁 Updating ModulesPermalink

You can later run:

hugo mod tidy   # Clean up unused modules
hugo mod get -u   # Update all modules

What are frequently used hugo commands?Permalink

Here are the most frequently used Hugo commands, grouped by purpose, to help you manage your site efficiently:

🚀 Development & PreviewPermalink

🏗️ Build & DeploymentPermalink

🧰 Module Commands (for Hugo Modules)Permalink

📝 Content CreationPermalink

🧪 Troubleshooting & UtilitiesPermalink

What does this command doesPermalink

hugo mod init github.com/googleforgames/agones/site

initializes a Hugo Module in your current Hugo site directory with the specified module path: github.com/googleforgames/agones/site.

Here’s a breakdown of what it does:

✅ What It Does:Permalink

1. Initializes Hugo Modules in the current site folder (if not already initialized).
2. Creates a go.mod file with the module path github.com/googleforgames/agones/site, used to manage Hugo modules with Go Modules under the hood.
3. Prepares the site for using themes or components as Hugo modules, which can then be fetched, versioned, and updated using Go tooling (hugo mod get, etc.).

4. This setup is useful especially when:

   • You’re working on a Hugo site that’s part of a larger GitHub repo (like Agones).
   • You want to import themes or shared components via Go module paths instead of submodules or manual copying.

📁 Example Output:Permalink

It will generate a go.mod file like:

module github.com/googleforgames/agones/site

go 1.20

require (
    github.com/some/theme v1.0.0
)

This tells Hugo and Go which module your site represents and what dependencies it may have.

What are pupular hugo modules? where are stored in directory structure? How to use them?Permalink

Hugo Modules are a powerful way to reuse components like themes, partials, shortcodes, or entire content structures across multiple Hugo projects.

Hugo Modules are a Go Modules-based system that allows you to:

• Import themes, partials, shortcodes, and assets as dependencies.
• Version and manage them cleanly.
• Share and reuse code easily across sites.

They’re declared in config.toml (or config.yaml) and managed via go.mod.

🔥 Popular Hugo ModulesPermalink

Here are some widely used Hugo modules:

📁 Where Are Hugo Modules Stored?Permalink

Hugo modules are not stored directly inside your project unless you vendor them.

They are:

• Downloaded to your Go module cache (usually ~/go/pkg/mod/)
• Mounted virtually into your site at build/runtime

But if you vendor them (for reproducibility):

hugo mod vendor

Then they go into:

/my-hugo-site/
├── themes/
│   └── <module contents>
├── go.mod
├── go.sum

⚙️ How to Use Hugo Modules?Permalink

🛠️ Step-by-Step

1. Initialize module (if not already):

hugo mod init github.com/yourname/yoursite

1. Add a theme or module as a dependency:

# config.toml
theme = ["github.com/theNewDynamic/gohugo-theme-ananke"]

Or in config.yaml:

theme:
  - github.com/theNewDynamic/gohugo-theme-ananke

1. (Optional) Mount parts of the module:

[module]
  [[module.mounts]]
    source = "assets"
    target = "assets"

  [[module.mounts]]
    source = "layouts"
    target = "layouts"

1. Run Hugo:

hugo server

If everything is correct, Hugo fetches and mounts the module.

1. (Optional) Vendor your modules:

hugo mod vendor

This copies the module code into themes/ and avoids downloading on every build.

📌 Useful Hugo Module CommandsPermalink

hugo mod init github.com/your/module   # Initialize
hugo mod get   # Fetch new deps
hugo mod tidy    # Clean unused deps
hugo mod vendor    # Copy modules into /themes
hugo mod graph   # Show dependency tree

What is hugo pipeline and how to use this?Permalink

In Hugo, the Hugo Pipes (or Hugo Asset Pipeline) refers to a built-in feature for processing and optimizing assets like CSS, JavaScript, and images during site generation. It’s particularly useful when you’re working with themes like Docsy or building custom layouts that need dynamic asset handling.

🔧 What Hugo Pipes Can DoPermalink

Hugo Pipes can:

1. Concatenate files (e.g., bundle multiple CSS/JS files).
2. Minify CSS/JS to reduce file size.
3. Fingerprint files (hashing to enable cache busting).
4. Compile Sass/SCSS to CSS.
5. Process images (resize, crop, convert format).

⚙️ Example Use in baseof.html (SCSS pipeline)Permalink

Here’s a common Hugo Pipes pipeline used in a theme like Docsy:

<link rel="stylesheet" href="" integrity="">

What this does:

• resources.Get loads the SCSS file.
• toCSS compiles SCSS to CSS.
• minify reduces CSS file size.
• fingerprint adds a content hash for cache busting.
• RelPermalink creates the final link.
• integrity supports Subresource Integrity (SRI).

🔁 JavaScript Pipeline ExamplePermalink

<script src="" integrity=""></script>

🧪 Image Processing ExamplePermalink

<img src="" width="" height="">

✅ RequirementsPermalink

• Hugo Extended version (needed for SCSS support).
• Your assets should be in the assets/ directory (not static/).
• Place these pipelines inside your layouts/_default/baseof.html or any other template file.

📁 Folder Structure for Hugo PipesPermalink

my-site/
├── assets/
│   ├── js/
│   │   └── main.js
│   └── scss/
│       └── styles.scss
├── layouts/
│   └── _default/
│       └── baseof.html

What is purpose of static and assets folder in hugo project?Permalink

✅ Hugo Assets vs Static Folder — In a NutshellPermalink

🗂️ assets/ folder

• Use it when you want Hugo to process the files during the build (via Hugo Pipes).

• Examples:

  • Compile SCSS to CSS
  • Minify JavaScript
  • Resize or optimize images
  • Fingerprint files for cache busting
• These files are not directly accessible via URL.
• The transformed output is automatically placed into the public/ folder during build.

📁 static/ folder

• Use it for raw files that don’t need processing.

• Examples:

  • Plain images (.jpg, .png)
  • Ready-made CSS/JS files
  • Fonts or downloadable PDFs
• These files are copied as-is to the public/ folder and are directly accessible via /filename.ext.
• Faster build time, since Hugo doesn’t touch them.

🚀 Rule of ThumbPermalink

🧠 “If transformation is needed → assets/. If it’s ready to serve → static/.”

What format is better hugo.toml or hugo.yaml?Permalink

Both config.toml and config.yaml work equally well in Hugo — the choice depends on your preference or your team’s conventions. Here’s a comparison to help you decide:

✅ TOML (default & popular)Permalink

Pros:

• Default in Hugo documentation and starter templates.
• Simple, clean syntax for small to medium configs.
• Better for nested tables (hierarchical data).

Example:

baseURL = "https://example.com"
languageCode = "en-us"
title = "My Hugo Site"

[params]
  author = "Alice"
  description = "A cool site"

✅ YAML (more common in DevOps)Permalink

Pros:

• Familiar to people from DevOps, CI/CD, or Kubernetes backgrounds.
• Great for complex structured data.
• Many IDEs support auto-completion and linting.

Example:

baseURL: "https://example.com"
languageCode: "en-us"
title: "My Hugo Site"

params:
  author: "Alice"
  description: "A cool site"

SummaryPermalink

🔄 You can also use JSON

Hugo also supports config.json, but it’s rarely used due to verbosity.

💡 Tip: If you’re using multiple environments (config.production.toml, etc.), stick with one format for consistency.
