v3.0.0

view-json-react v3 is a focused, read-only React JSON and JavaScript value inspector rebuilt for safety, accessibility, large datasets, and dependable package consumption.

Highlights

• Genuine WAI-ARIA tree semantics with complete keyboard navigation, type-ahead, managed focus, and accessible clipboard feedback.
• Bounded, iterative inspection with cycle detection, getter safety, Proxy failure handling, typed paths, and explicit non-JSON value rendering.
• Controlled and uncontrolled expansion, bounded full-tree search, deterministic sorting, expandable strings, themes, RTL, and custom leaf rendering.
• Optional dependency-free windowing through view-json-react/virtual; the standard entry does not pay for virtualization.
• Separate headless utilities through view-json-react/headless.
• Static CSP-friendly CSS, SSR-safe rendering, React Server Component boundaries, ESM and CommonJS, and version-matched declaration graphs.
• Zero runtime dependencies with React 18 and React 19 support.
• Bundled llms.txt and Agent Skill guidance for version-aware AI coding tools.

Breaking changes from v2

• Import view-json-react/styles.css once in your application.
• Clipboard operations now report their asynchronous result through CopyResult.
• Array path segments are numbers, while rootName remains display-only.
• Public package access is limited to the documented root, virtual, headless, stylesheet, and package metadata entries.

See the v2 → v3 migration guide for examples and the complete migration sequence.
