Technical Kiwi Limited — Website

A small business site built with Go, templ (server-side HTML templates), and HTMX for gallery interactions.

Requirements

• Docker and Docker Compose

Quick start

cp .env.example .env   # optional SMTP settings
make dev               # live reload → http://localhost:7331

Make targets

Target	Description
make dev	Dev with Air + templ browser live reload (default)
make build	Build production website image
make up	Run production website service
make down	Stop dev and prod compose stacks
make generate	Run templ generate in dev container
make tidy	Run go mod tidy in dev container
make logs	Follow dev container logs
make sync-media	Copy photos and convert videos from upload/ → app/images/
make thumbs	Generate gallery thumbnails and video posters under app/images/
make publish	sync-media then thumbs

Features

• Single-page layout: hero, services, gallery, contact
• Gallery loads via HTMX (hx-get="/gallery")
• Lightbox modal with previous/next navigation
• Contact form with SMTP relay (HTMX submit, no page reload)
• Serves gallery media from app/images/ (published copy; not in git)
• Password-protected gallery admin at /admin/

Gallery admin

Set both ADMIN_USER and ADMIN_PASSWORD in .env, then open http://localhost:8080/admin/ (or via your public URL).

• Sign in with username/password
• Upload JPEGs into an album (or create a new album folder)
• Delete images (removes originals and generated thumbs/hero)
• Changes appear on the public site immediately

Contact form (SMTP)

Set relay details in .env:

Variable	Description
SMTP_HOST	Relay hostname (required)
SMTP_PORT	Port (default 587)
SMTP_USER / SMTP_PASSWORD	Auth if your relay requires it
SMTP_FROM	Envelope/header From address (required)
SMTP_TO	Where contact messages are delivered (required)
SMTP_TLS	auto, tls (465), or plain (25/local relay)

If SMTP is not configured, the page shows a mailto fallback instead of the form.

Dev container

make dev uses compose.dev.yaml: mounts ./app and ./upload (raw media staging) plus your host Go caches (~/go/pkg/mod, ~/.cache/go-build by default). Override with GOMODCACHE / GOCACHE in .env. Prefer make dev without sudo so those paths resolve correctly.

Use http://localhost:7331 in the browser — the templ proxy injects live reload on .templ, .go, and .css changes. Port 8080 hits the app directly without auto-reload.

Only run dev or website at a time if you map both to the same host ports.

make up uses compose.prod.yaml: production website mounts ./app/images into the container. Uncomment the Caddy network/labels in that file when deploying behind your reverse proxy.

Gallery media

1. Drop photos and videos into repo-root upload/ (album folders, same layout as the gallery).
2. Run make sync-media — JPEGs are copied; videos are converted to H.264 MP4 in app/images/.
3. Run make thumbs (or make publish for both steps) — builds thumbs/ and hero/ derivatives under app/images/.

The site serves files from app/images/ at /images/…. Thumbnails and hero images are gitignored and rebuilt when sources are newer.

Deploy notes

After adding media, run make publish on the host before or after deploy. First request may take a moment while any missing thumbnails are generated.
