Trying calsdk means installing it and writing a script first, and the real providers need OAuth credentials before anything works. That's a lot to ask of someone who just wants to see the API.

This adds examples/playground, a small Vite page that opens on StackBlitz with nothing to install:

• Two in-memory calendars (@cal-sdk/mock), a weekday standup with Wednesday's moved, and the hour-long slots when both calendars are free, drawn as a week.
• It depends on the published @cal-sdk/core and @cal-sdk/mock from npm, so StackBlitz can install it from this folder alone.
• Linked from the README and the quickstart: https://stackblitz.com/github/vkpdeveloper/calsdk/tree/main/examples/playground?file=src/main.ts (the link works once this is on main).

Verified

• Copied the folder to a temp directory, ran npm install from the registry and vite, as StackBlitz will. It rendered the week with no errors, and the free slots respect both calendars. There was no horizontal overflow at 1280px or at 375px.
• biome check . and bun run typecheck pass.

Summary by CodeRabbit

• New Features
  • Added a browser-based calendar playground with two sample calendars, a recurring standup with a moved occurrence, a combined week view, and shared free-time slots.

Walkthrough

The PR adds a browser-based calendar playground with mock calendars, recurring events, shared free-time slots, and a date-grouped week view. The README and quickstart link to the playground.

Changes: Browser Calendar Playground

Layer / File(s)	Summary
Build and render the calendar demo examples/playground/package.json, examples/playground/index.html, examples/playground/src/main.ts, examples/playground/README.md	The playground uses two mock calendars with sample events. It expands a recurring standup, moves a matching November 11 occurrence when present, finds shared 60-minute free slots, and renders events and slots in date-grouped columns. The README describes local setup and use.
Link to the playground README.md, apps/web/content/docs/quickstart.mdx	The README and quickstart add links to the StackBlitz playground. The README also directs readers to try editing code before installing packages.

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

Change: Feature

Merge Risk: Low · previous review 3d39d

The mock demo has bounded issues: local setup needs an SDK build, and added all-day events display on the wrong date. Real-calendar instructions should explicitly keep credentials behind a server API. These localized corrections warrant owner attention.

Full details: Title check

Explanation

The title "feat(examples): browser playground on StackBlitz" matches the main change. The PR adds examples/playground, a Vite page that runs calsdk in the browser with two in-memory calendars. The README and quickstart link to it, and a StackBlitz link is provided. The title is short, specific, and uses a conventional commit prefix.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files. (5 skipped: 5 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Inline comments:
Review comments at @examples/playground/package.json:
- Around line 9-10: Update the playground setup instructions to build the SDK
packages after installing dependencies and before starting the dev server, so
the dist exports for @cal-sdk/core and @cal-sdk/mock are available on a fresh
checkout.

Review comments at @examples/playground/README.md:
- Line 12: Update the README guidance around `src/main.ts` so it no longer
suggests placing `accessToken` or creating Google or Microsoft providers in
browser-loaded code. Direct readers to create the provider in server-side code
behind their own API and have the page call that API.

Review comments at @examples/playground/src/main.ts:
- Around line 65-66: Update the start value used when building items so all-day
event dates are interpreted as midnight in the playground’s configured time zone
before formatting. Preserve event.start.dateTime for timed events, and avoid a
fixed UTC offset that would be incorrect when daylight-saving rules change.

Build the SDK packages before running the playground.

Bun links @cal-sdk/core and @cal-sdk/mock to the local workspace packages. Their exports point to dist/, which is gitignored and not built by bun install. On a fresh checkout, Vite cannot resolve these imports, so the page does not load.

Suggested README change

 bun install
+bun run build
 bun run --cwd examples/playground dev
