## What it is
A set of starter templates for building full-featured Progressive Web Apps using web components, including a manifest, service worker, responsive layout, Redux state management, and routing out of the box. The project is explicitly no longer under development, with users directed to the open-wc application scaffold generator for LitElement projects instead.

## Use cases
- scaffold a progressive web app with web components
- starting point for an offline-capable PWA
- template with service worker and manifest preconfigured
- example of Redux state management in a web components app
- learn the PRPL pattern for fast time-to-interactive
- starter project with unit and integration testing setup

## When to choose
- you want a ready-made PWA template with web components and offline support
- you need a reference implementation of the PRPL pattern and Redux in a web components app
- you are maintaining or forking an existing project already built on this kit

## When to avoid
- you are starting a new project today, since the project is no longer maintained and open-wc generators are recommended
- you need a framework with active support, security updates, or modern tooling
- you prefer React, Vue, or other component frameworks rather than web components

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: state-management, routing, templating, testing, web-framework
- domain: web-development, frontend, developer-tools
- platform: cross-platform
- tags: pwa, web-components, starter-template, redux, service-worker, lit-element, prpl-pattern, offline-first, boilerplate, web-server, nodejs
