This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Commands

All tasks run via Deno. Use deno task instead of npm run.

deno task dev          # start dev server
deno task build        # production build
deno task preview      # preview production build
deno task check        # svelte-kit sync + svelte-check (type checking)
deno task lint         # ESLint
deno task test         # run all Playwright e2e tests

Run a single e2e test file:

DENO_DIR=/home/developer/.cache/deno deno run -A npm:playwright test src/routes/path/to/page.svelte.e2e.ts

Format source files (Svelte component formatting requires the fmt-component unstable flag, already set in deno.json):

deno fmt

Architecture

This is a SvelteKit app using Svelte 5 with Deno as the runtime and package manager.

Key conventions

  • Svelte 5 runes mode is enforced globally via svelte.config.js. All components must use the runes API ($props(), $state(), $derived(), $effect(), etc.). The runes: true compiler option is applied to every file outside node_modules.
  • $lib maps to src/lib/. Put shared components, utilities, and assets there.
  • File-based routing under src/routes/. Each route segment is a directory; +page.svelte is the page, +layout.svelte wraps child routes.
  • E2e tests are collocated with routes using the .e2e.{ts,js} extension (e.g., src/routes/demo/playwright/page.svelte.e2e.ts). Playwright's testMatch is set to this pattern.

Config files

  • deno.json — Deno tasks, formatter config (fmt-component unstable flag for Svelte files), and the DENO_DIR cache.
  • package.json — npm-compatible dependency declarations consumed by Deno's npm compatibility layer.
  • svelte.config.js — SvelteKit adapter (adapter-auto) and runes enforcement.
  • playwright.config.ts — e2e tests run against a production build (not dev server) on port 4173.
  • tsconfig.json — extends the generated .svelte-kit/tsconfig.json; strict mode enabled.

Environment

The Deno npm cache is not at the default location. When running deno commands directly (not via deno task), set:

DENO_DIR=/home/developer/.cache/deno
