Building a Web App with Go and HTMX
summary
Builds a working CRUD gardening app called Let's Go (and earlier BanterBus) using Go, HTMX, templ, tailwindcss and Postgres and keeps the frontend minimal so code stays simple and reviewable. Uses SQLC for handwritten SQL, Temple for Temple LSP typed templates, Air + file-watch for hot reloads, Playwright in Go for E2E, Nix for reproducible dev shells, cookies for auth and HTMX websockets for realtime; HTMX is tiny (50KB HTMX) and returns HTML snippets so backend holds state and redirects use HX-Redirect headers.
