## What it is
Durandal is a cross-device, cross-platform JavaScript client framework for building Single Page Applications (SPAs). The project is no longer active and has been superseded by Aurelia, its next-generation successor.

## Use cases
- build single page applications in javascript
- maintain a legacy durandal spa
- evaluate durandal vs aurelia for a new project
- migrate a durandal app to aurelia
- cross-platform client-side app framework for pc, mac, ios and android

## When to choose
- you are maintaining an existing Durandal-based SPA
- you need a stable, MIT-licensed legacy framework for an old codebase

## When to avoid
- starting any new project - use Aurelia instead
- you need active maintenance, security fixes, or modern tooling
- you want TypeScript-first development or modern build pipelines

## Facets
- artifact type: framework
- maturity: abandoned
- function: frontend-framework, routing, state-management
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: spa, single-page-application, mvvm, superseded-by-aurelia, legacy, javascript
