## What it is
Pug is a high-performance, feature-rich template engine for Node.js and browsers, heavily influenced by Haml, that compiles indentation-based templates to HTML. It is a mature, widely used library distributed as a set of npm packages.

## Use cases
- render html templates in a node.js express app
- write cleaner html with an indentation-based template language
- generate static html pages from templates
- server-side render views for a web application
- migrate from haml or jade to a maintained template engine
- compile templates for use in the browser

## When to choose
- you want a concise, whitespace-sensitive template syntax instead of verbose html
- you are building a Node.js web app (e.g., Express) and need view templating
- you need a mature, battle-tested engine with a large ecosystem and long track record

## When to avoid
- your team prefers plain HTML templates with minimal syntax (consider Handlebars or EJS)
- you need React/Vue-style component-based frontend rendering
- you dislike significant-whitespace syntax or want HTML-valid template files

## Facets
- artifact type: library
- maturity: stable
- function: templating, web-framework, parser
- domain: web-development, frontend, backend, web-design
