@spatialpack/core

The engine behind SpatialPack — a standards-first glTF / GLB / USDZ toolkit, in pure TypeScript. It powers analyze, optimize (KTX2 / meshopt / WebP / AVIF / Draco), recipe search, commerce-readiness scoring + autocorrect, USDZ / USDC validation and USDA ↔ USDC round-trip, visual-diff metrics, and Gaussian-splat ingest.

Most users want the CLI, not this package. Install @spatialpack/cli (npm i -g @spatialpack/cli) for the command-line surface, or @spatialpack/sdk for a friendly programmatic wrapper. Install @spatialpack/core directly only if you're building on the low-level engine.

Usage

import { analyzePath, optimizePath } from '@spatialpack/core';

const report = await analyzePath('model.glb');                 // per-mesh/material/texture stats
const result = await optimizePath('model.glb', { preset: 'web-mobile' });

The package ships fine-grained subpath exports — e.g. @spatialpack/core/analyze, /optimize, /recipe-search, /visual-diff, /conformance, /io, /splat-input — so consumers pull only what they need. See package.json exports for the full list.
