## What it is
Eco is a templating library that embeds CoffeeScript logic inside markup, similar to EJS or ERB. Templates can be rendered server-side in Node.js or precompiled to JavaScript with a CLI for client-side rendering.

## Use cases
- render HTML views from CoffeeScript templates in Node.js
- compile templates to JavaScript for client-side rendering
- embed CoffeeScript conditionals and loops in markup
- escape and interpolate context data into HTML
- call helper methods from within templates

## When to choose
- your codebase is written in CoffeeScript and you need server-side or client-side templating
- you want EJS/ERB-style templates with CoffeeScript syntax
- you need synchronous template rendering with helper methods

## When to avoid
- you use modern JavaScript or TypeScript instead of CoffeeScript
- you need async template rendering
- you want an actively maintained templating engine
- you're starting a new project with modern tooling

## Facets

- maturity: abandoned
- function: templating
- domain: web-development, frontend, developer-tools
