## What it is
A library for bundling web project assets (HTML imports, scripts, stylesheets) for production to minimize network round-trips. It is part of the Polymer tooling ecosystem and has been migrated into the Polymer/tools monorepo.

## Use cases
- bundle html imports into a single file
- reduce network round-trips for web components
- inline scripts and stylesheets for production builds
- customize bundling strategy for polymer projects
- package web components for deployment

## When to choose
- you maintain a legacy Polymer project using HTML imports
- you need fine-grained control over web component bundling strategy
- you want a programmatic bundling library rather than a CLI wrapper

## When to avoid
- you are starting a new modern web project (HTML imports are deprecated)
- you want general-purpose JavaScript bundling like webpack or rollup
- you need actively developed tooling with modern ecosystem support

## Facets
- artifact type: library
- maturity: maintenance
- function: build-tool, developer-tools
- domain: web-development, frontend, developer-tools
- platform: cli
- tags: web-components, polymer, html-imports, bundling, typescript, nodejs
