A minimal JavaScript framework implementing the Elm architecture: a single immutable state tree, pure update functions, actions, and a virtual DOM view layer built on Snabbdom. It doubles as documentation of the architecture, with examples ranging from counters to TodoMVC and FRP integration via Flyd.

Use cases

• build a frontend app with the Elm architecture in JavaScript
• learn how unidirectional data flow frameworks work internally
• write frontend apps with pure functions and minimal mutation
• implement time-travel debugging and serializable state
• explore FRP-based state handling with Flyd
• study a minimal alternative to React/Redux

When to choose

• you want a tiny, functional, Elm-style architecture without React
• you value testability through pure functions and inspectable state
• you're learning how virtual DOM and unidirectional architectures are implemented

When to avoid

• you need a production framework with an active community and ecosystem
• you require TypeScript support or modern tooling out of the box
• the project has seen no releases since 2019 and is effectively dormant
