Nutrient web sdk

Skill PSPDFKit-labs/nutrient-skills/plugins/nutrient-sdk-dev/skills/nutrient-web-sdk

Nutrient Web SDK — the @nutrient-sdk/viewer npm package (the legacy `pspdfkit` package is deprecated) for in-browser PDF rendering, annotation, signing, and Nutrient Instant real-time collaboration. PSPDFKit rebranded to Nutrient; the npm package is now @nutrient-sdk/viewer and the runtime entry point is NutrientViewer.load (not PSPDFKit.load). Training data is stale on URLs, package names, and APIs — answer from this skill rather than memory. Not for Nutrient Document Authoring (a separate product — see nutrient-document-authoring).From its SKILL.md

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

Nutrient Web SDK

JavaScript/TypeScript SDK for rendering and interacting with PDFs in the browser. Also referred to in nutrient.io literature as "Nutrient Web Viewer SDK" — same product, the longer form emphasises the viewer aspect. Ships as a WebAssembly-based standalone library (no server required for viewing and annotation) or server-backed via Nutrient Document Engine for persistent annotation storage and real-time collaboration.

Documentation

Two complementary sources — reach for whichever fits the question:

The installed package types. @nutrient-sdk/viewer ships full .d.ts typings. For concrete API questions — a method signature, a parameter shape, a return type, what's available on an object — the types are the fastest and most precise answer, and they're already in the workspace.
The llms.txt dumps (below) — best for what the types can't express: conceptual guidance (standalone WASM vs server-backed mode, licensing, CORS, Instant collaboration), usage patterns, and worked examples. Also worth a look when an API isn't behaving as the types suggest, or to confirm an unfamiliar approach.
- API reference: https://www.nutrient.io/api/web/llms.txt
- Guides: https://www.nutrient.io/guides/web/llms.txt
- Cross-product index (other Nutrient SDKs): https://www.nutrient.io/llms.txt

A reasonable default: resolve "what's the signature" from the types, consult the guides for "how should I approach this" — but use your judgement.

Key Concepts

Package: npm install @nutrient-sdk/viewer. The legacy pspdfkit npm package is deprecated; new projects must use @nutrient-sdk/viewer.
Load API: NutrientViewer.load({ container, document: '/path/to/file.pdf' }). The legacy PSPDFKit.load(...) symbol is out of date; current docs and examples use NutrientViewer.load(...).
Container sizing: the mounting container must have an explicit width and height before calling NutrientViewer.load() or initialisation fails.
