How to manage state in Superfine applications?

Superfine doesn't include state management, so you need to handle it manually or use external libraries like Redux. The examples show using plain JavaScript objects and functions to update state and trigger re-renders with patch().

Superfine vs Hyperapp: what's the difference?

Superfine is the core view layer of Hyperapp without the framework parts—it's more minimal. Choose Superfine if you want to build your own state management, or Hyperapp if you prefer a built-in Elm-like architecture with effects and subscriptions.

Is Superfine good for large-scale projects?

While its efficient diffing helps, Superfine lacks built-in optimizations like React's concurrent features. For large apps, you might need to implement custom performance tweaks and robust state management, which can be challenging.

How does server-side rendering work with Superfine?

Superfine supports SSR recycling by patching over existing HTML, but you must ensure server and client markup match. It requires manual setup for server-side generation, unlike frameworks with built-in SSR solutions like Next.js.

Can I use JSX with Superfine without Babel?

No, JSX requires compilation with Babel and a custom pragma function, as detailed in the README. While possible, it adds configuration overhead compared to frameworks that support JSX natively or with simpler setups.

What are the performance benefits of Superfine over vanilla JS?

Superfine's virtual DOM diffing minimizes DOM updates, reducing reflows and repaints compared to manual DOM manipulation. However, for very simple UIs, vanilla JS might be faster due to no abstraction overhead.

What is superfine?

Superfine is a minimal view layer for building web interfaces using a virtual DOM approach. It provides core functions to create virtual nodes and efficiently patch the DOM, solving the need for a lightweight, framework-agnostic way to manage UI updates. At just 1 kB, it focuses on performance and flexibility without imposing a full framework architecture.

Target Audience

Frontend developers who need a tiny, flexible view layer for projects where bundle size is critical, or those who want to pair a virtual DOM with their own state management solution.

Value Proposition

Developers choose Superfine for its extreme minimalism (1 kB) and lack of framework lock-in, allowing them to build custom architectures while still benefiting from efficient DOM updates via virtual DOM diffing.

Overview

Absolutely minimal view layer for building web interfaces

Use Cases

Best For

Building ultra-lightweight web applications where every kilobyte counts
Adding efficient DOM updates to custom state management setups
Creating simple interactive widgets without a full framework
Prototyping interfaces quickly with minimal tooling
Integrating a view layer into existing projects without rewriting architecture
Educational projects to learn virtual DOM fundamentals without framework complexity

Not Ideal For

Projects requiring built-in state management, lifecycle hooks, and effects without additional setup
Teams that need a comprehensive ecosystem with pre-built components, routing, and tooling out of the box
Large-scale applications where extensive documentation, community support, and stable APIs are critical

Pros & Cons

Pros

Extremely Lightweight

At just 1 kB minified+gzipped, Superfine is one of the smallest view layers, significantly reducing bundle size for performance-critical applications as highlighted in the README.

Efficient DOM Updates

Uses virtual DOM diffing to update only changed parts of the DOM, avoiding full re-renders, as demonstrated in the counter and todo app examples with patch().

Maximum Flexibility

Designed to work standalone or integrate with any state management library, offering no framework lock-in, which aligns with its philosophy of providing the bare minimum.

SSR Recycling Support

Can patch over server-rendered HTML, recycling existing elements for better SEO and faster initial loads, with clear examples and warnings about markup mismatches in the README.

Cons

No Built-in Abstractions

Lacks state management, effects, and subscriptions, forcing developers to handle these manually or integrate external libraries, increasing complexity and boilerplate code.

JSX Setup Overhead

Requires Babel configuration and a custom pragma function for JSX support, adding setup steps compared to frameworks with native JSX integration, as noted in the JSX section.

Limited Ecosystem

Being a minimal library, it has fewer community resources, plugins, and pre-built components than larger frameworks like React or Vue, which can slow down development for complex features.
