The playground's seven toolbar controls now live in the query string via nuqs, and an edited document is stored as lz-string-compressed content, so a playground link reproduces exactly what you were looking at. Parameters left at their default stay out of the URL, and writes use replaceState so browser history stays Astro's.

Summary by CodeRabbit

  • New Features
    • Playground editor settings can now be stored and shared through URL parameters.
    • Added support for sharing markdown documents using compact, URL-safe links.
    • Editor mode, spellcheck, presets, read-only state, block handles, caret behavior, and source settings can be configured from the URL.
  • Bug Fixes
    • Empty shared documents are now handled correctly when loaded from a link.

Review Change Stack

📝 Walkthrough

Walkthrough

The playground now stores editor settings and shared markdown in URL query parameters. It uses nuqs for state management and lz-string for compressed document content. The demo runs inside NuqsAdapter.

Changes

Playground URL sharing

Layer / File(s) Summary
Query parameter contract
website/package.json, website/src/stories/playground-params.ts
Adds nuqs and lz-string. Defines playground parameter constants, defaults, and compressed content parsing.
Editor URL state integration
website/src/stories/main-editor.tsx
Replaces local editor settings with query state. Preset selection, source toggling, editor controls, and markdown sharing update URL parameters. The demo is wrapped in NuqsAdapter after mount.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 4b30b

Shared playground links can load arbitrary document content, including remote images, and queued updates may cause the URL, selected preset, and visible document to disagree or expose older text when a link is copied. Unbounded compressed content can also impose excessive browser work, so the PR needs explicit owner awareness and follow-up before it is merge-ready.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Cancel queued synchronization before changing the preset.

If a user edits the source pane and selects a preset within SYNC_THROTTLE_MS, queued pullFromSource work can call writeRichText with pre-switch Markdown. Line 128 then restores that Markdown and content after Line 163 cleared it. The selected doc and the displayed document then disagree, and a reload restores the old shared content.

Invalidate both queued sync directions before applying the preset. Then clear content and set the preset Markdown.

Also applies to: 163-163
