## What it is
Hogan.js is a JavaScript compiler for the Mustache templating language, developed at Twitter. It compiles templates into standalone HoganTemplate objects with render methods, and can precompile templates on the server for use in the browser.

## Use cases
- compile mustache templates to JavaScript
- render templates in the browser with dynamic data
- precompile templates ahead of time with an asset packager
- parse and scan mustache template syntax on the server
- compile template files to JS from the command line with hulk

## When to avoid
- you need an actively maintained templating library
- you want modern template features beyond the Mustache spec
- you are starting a new project and can choose a maintained alternative

## Facets
- artifact type: library
- maturity: abandoned
- function: templating, compiler, parser
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: mustache, template-engine, precompilation, twitter, nodejs, javascript
