@neutro/view

Fine-grained reactive view engine for the web.

Signal-native reactivity

Two authoring surfaces

Write components in compiled .nv files with ergonomic assignment-erasure, or use the html tagged template directly — no build step, no plugin required.

No virtual DOM

A keyed reconciler moves real DOM nodes directly. No diffing, no patching, no runtime overhead per update.

Fine-grained updates

Each reactive binding is a single effect that updates exactly one DOM attribute or text node. Updates are surgically targeted, never component-wide.

Keyed reconciler

List reorders move existing DOM nodes with insertBefore rather than destroying and rebuilding them — preserving focus, scroll position, and input values across updates.

Framework-portable

No framework lock-in. The engine ships as a single npm package usable from any build toolchain or served as a plain ES module with no bundler.

Why @neutro/view?

Most view libraries pay a per-update tax: reconcile a virtual DOM, diff component trees, patch the real DOM. @neutro/view skips all of that. Signals track exactly which DOM nodes depend on which values — when a signal changes, only those nodes update. No diffing pass, no component re-render, no scheduler.

const Counter = $component(() => {
  $script(() => {
    const count = signal(0)
  })
  $render(() => html`
    <div>
      <p>${count}</p>
      <button @click="${() => count = count + 1}">+</button>
    </div>
  `)
})

Write natural signal reads and assignments — the compiler erases them to efficient accessor calls at build time. No manual .get() / .set().
