## What it is
jsblocks is a JavaScript MV-ish UI framework from 2012, inspired by Knockout, for building everything from simple interfaces to complex single-page applications with server-side rendering. The author explicitly states it is now a showcase of early skills and is no longer actively developed.

## Use cases
- build a single-page application with a knockout-style framework
- server-side render a javascript ui
- two-way data binding for web apps
- study a pre-react javascript ui framework
- build an mvc-style frontend in vanilla javascript

## When to choose
- maintaining or extending an existing codebase already built with jsblocks
- studying the history and design of pre-React JavaScript frameworks

## When to avoid
- starting any new project
- needing long-term support, security updates, or an active community
- building a modern production web application

## Facets
- artifact type: framework
- maturity: abandoned
- function: frontend-framework, ssr, state-management, templating
- domain: web-development, frontend
- platform: browser
- tags: mvvm, knockout-inspired, single-page-applications, legacy, showcase-project, nodejs
