Make static Hugo sites dynamic with htmx and go
This is a project template combining Hugo, htmx, and an optional API server written in Go, using html/template
or templ for HTML rendering.
You can see this template in action at https://garbagespeak.com and its source code is at https://github.com/acaloiaro/garbagespeak.com
Hugo is a fantastic static site building tool, and there are few things about Hugo that can or should be improved.
The existence of this project template does not suggest that all static sites should be dynamic. If your site can be static, it should be static.
Yet there are instances in which one might want to add dynamic functionality to static Hugo sites. That is the purpose of this project template. Not to make all static sites dynamic, but to provide a simple solution to add islands of dynamic behavior to static sites.
This allows us to build fast, easily deployable HTML content, with the added ability of meeting a new class of dynamic behavior needs.
Example use cases include
- Contact forms
- Comment systems
- Up/Down vote systems
- You know ... website stuff
You shouldn't have to reach for a SaaS product to offer dynamic content on your static sites.
First of all, what is meant by "project template"?
This git repository is to be used as a template from which to create Hugo sites. It does not impose any constraints on how you use Hugo. It is, itself, a simple hugo project created with hugo site new ...
. You can run hugo serve
from this project's root directory and it will behave like every other Hugo site you've developed.
So what does this template provide?
This template provides example code and simple developer tooling for running Hugo along with an optional API server, written in Go, using html/template
.
What developer tooling is provided?
bin/develop
: This utility both starts the hugo server (hugo server
) and the API server (go run server.go
) for development. If the user hasair
installed (https://github.com/cosmtrek/air), API server code will hot-reload when changes to server.go are made.bin/build
: This utility builds a binary of your API (server.go
), with your entire Hugo site embedded within. This allows Hugo sites to be deployed as a self-contained binary.
Clone this project template and initialize it:
git clone git@github.com:acaloiaro/hugo-htmx-go-template.git ./my_new_site
cd my_new_site
# The theme 'ananke' is used here because it's the one used by Hugo's quickstart guide: https://gohugo.io/getting-started/quick-start/
# You can use any theme with this project template, so long as you add htmx to its included scripts: <script type="text/javascript"src="/htmx.js"></script>
# fetch-deps.sh does this automatically for the ananke theme
git clone https://github.com/theNewDynamic/gohugo-theme-ananke ./themes/ananke
bin/fetch-deps.sh
go build -o bin/develop internal/cmd/develop/main.go
go build -o bin/build internal/cmd/build/main.go
mkdir public && touch public/.empty
If you'll be using the API server, it's useful to install air
to hot redeploy Go code changes when running bin/develop
:
go install github.com/cosmtrek/air@latest
To make changes to templ
templates (.templ files), first install templ
. Using templ
is optional. The goodbye world example shows templ
in action.
go install github.com/a-h/templ/cmd/templ@latest
Run locally
To start the development server(s), run bin/develop
Hugo will run on its develop port at http://localhost:1313 and the API server runs on http://localhost:1314.
Example content is available at: http://localhost:1313/posts/hello-world/
bin/build
can be used to build fat binaries of your Hugo site, which will be available at http://localhost:1314 after running build/server
.
Changing templ
templates
To use templ
templates, you will need to templ
installed. The air
configuration watches for changes to templ
files and automatically builds them.
Hugo sites made from this template project can be deployed in two ways.
A traditional deployment is any deployment where Hugo content is deployed to an HTTP server that serves static content. Deploying Hugo content with this project template remains the same as a usual Hugo site.
However, to use the API server in production, you'll need to tell your static site content where to send HTTP requests.
Configure this in config/production/hugo.toml
If you've made your API available at https://api.example.com
, add the following to hugo.toml
:
[Params]
apiBaseUrl = 'https://api.example.com'
The API server binary can be had by using bin/build
to generate a fat binary, or simply compiling server.go
directly: go -o build/server server.go
Fat binary deployment is made possible by bin/build
. The build/server
executable contains both the API server code and Hugo static site content.
No additional configuration is necessary to deploy a fat binary. Simply copy build/server
to the system that will run it.
Note: To build fat binaries for different systems/architectures than the system performing the build, use the GOOS
and GOARCH
to change system/architecture, e.g.
Build a fat binary for OpenBSD and AMD64 architecture
GOOS=openbsd GOARCH=amd64 bin/build
