## What it is
CanJS is a collection of client-side JavaScript architectural libraries for building CRUD web applications with fewer lines of code. It provides Web Components via StacheElement, an observable model layer with real-time list updating, stache templating with promise support, and routing.

## Use cases
- build crud apps in javascript
- create web components with observable properties
- bind rest api data to frontend models
- auto-update lists after create update delete
- handle promise states directly in templates
- build long-lived complex single-page applications

## When to choose
- building data-heavy CRUD applications with a clean model/UI separation
- you want Web Components with live-bound templates and observables
- you need automatic real-time list updating with preserved filtering and sorting
- you value API stability for long-term maintainable apps

## When to avoid
- you want a large ecosystem and mainstream community like React or Vue
- starting a brand-new project where modern frameworks have more momentum
- you need server-side rendering or a full-stack meta-framework out of the box

## Facets
- artifact type: framework
- maturity: maintenance
- function: frontend-framework, templating, state-management, routing, ui-components
- domain: web-development, frontend
- platform: browser
- tags: web-components, crud, observable, model-layer, stache, data-binding, nodejs, javascript
