Foldkit: A new frontend framework built on Effect with Elm-like architecture
Key points
- Foldkit is a new frontend framework built on the Effect library.
- It adopts an architecture similar to Elm, with immutable state and a single update function.
- The framework includes built-in solutions for routing, UI components, and field validation.
- Side effects are modeled as values returned from the update function.
Introducing Foldkit
Foldkit is a new frontend framework designed to provide a structured approach to web application development. Unlike frameworks that focus solely on rendering, Foldkit offers a complete architecture, allowing developers to concentrate on their application's domain logic.
Architecture and State Management
The framework is built on the Effect library and follows principles similar to The Elm Architecture. It features a single, immutable model for the entire application state, with all changes flowing through a single update function. Side effects are explicitly modeled as values returned from this update function, rather than imperative calls within handlers.
Integrated Features
Foldkit includes several integrated features that are often separate libraries in other frameworks. These include type-safe bidirectional routing, accessible UI components built for The Elm Architecture, and per-field validation with synchronous and asynchronous support. It also introduces concepts like Submodels for self-contained components, Subscriptions for binding model slices to streams, and Managed Resources for handling browser resources like WebSockets.
Scalability and Maintainability
The framework emphasizes linear complexity growth, aiming for consistent patterns across applications of varying sizes. This design is intended to improve code readability and maintainability, making it easier for new team members to understand and contribute to projects.

Foldkit is a new frontend framework that provides an opinionated architecture for building web applications, based on the Effect library and inspired by The Elm Architecture. It aims to simplify development by offering predictable state management, explicit side effects, and integrated components for routing, UI, and validation.
