@immersive-scroll/core

Framework-agnostic immersive engine primitives. Use this package when you need the scene lifecycle, frame manifest handling, progress math, and plugin hooks without committing to a specific UI framework.

Install

pnpm add @immersive-scroll/core

What it exports

• createImmersiveEngine(): create the headless engine instance.
• normalizeImmersiveConfig() and mergeImmersiveConfig(): resolve partial config safely.
• createFrameStore() and createScrollStore(): low-level state stores.
• validateFrameManifest() and validateFrameDirectoryContract(): manifest and asset integrity helpers.
• Shared types and utilities re-exported from @immersive-scroll/shared.

Minimal example

import { createImmersiveEngine } from '@immersive-scroll/core';

const engine = createImmersiveEngine({
  config: {
    framesPath: '/immersive/story',
    scrollbar: { enabled: true }
  },
  container: document.querySelector('#scene'),
  targets: {
    canvas: document.querySelector('canvas')
  }
});

await engine.init();
await engine.updateProgress(0.35);

Use this package when

• you are building a custom adapter or wrapper,
• you need plugin or renderer control outside the packaged UI layers,
• or you want runtime logic on the server or in tooling without React, Solid, or custom elements.
