## What it is
templ is a typed HTML templating language for Go that compiles components into performant Go code for server-side or static rendering. It ships with strong developer tooling including IDE autocompletion and a language server (LSP).

## Use cases
- render html pages in go
- build server-side rendered go web apps
- create reusable html components in go
- generate static html files from go
- use htmx with go
- get ide autocomplete for go html templates

## When to choose
- you write Go web apps and want type-safe, compiled HTML templates
- you want server-side rendering without client-side JavaScript
- you need good IDE tooling and LSP support for templates
- you use frameworks like Chi, Echo, Gin, or Fiber and want a framework-agnostic templating layer

## When to avoid
- you need client-side interactivity or a full frontend framework like React
- your stack is not Go
- you prefer runtime-flexible templates over compiled ones
