CodeGarden

CodeGarden is a full-stack code snippet manager built with TanStack Start, PostgreSQL, Drizzle ORM, Better Auth, Shiki, and CodeMirror.

Stack

• TanStack Start with React 19
• PostgreSQL via postgres + Drizzle ORM
• Better Auth with the Drizzle Postgres adapter
• Server-side syntax highlighting with Shiki
• Client-side editing with lazy-loaded CodeMirror 6
• Tailwind CSS v4 + shadcn/ui

Local Setup

1. Install dependencies:

bun install

2. Create .env.local with:

DATABASE_URL=postgres://...
BETTER_AUTH_SECRET=generate-a-long-random-secret
BETTER_AUTH_URL=http://localhost:3000
VITE_SENTRY_DSN=

Generate a secret with:

bunx --bun @better-auth/cli secret

3. Apply the Drizzle SQL migrations in drizzle/ to your Postgres database.

4. Start the app:

bun --bun run dev

The app runs on http://localhost:3000.

Scripts

• bun --bun run dev starts the local dev server with dotenv + Sentry instrumentation.
• bun --bun run build builds the TanStack Start app and copies the server instrumentation file into dist/server.
• bun --bun run start runs the production server from dist/server/server.js.
• bun --bun run test runs Vitest in non-failing no-tests mode.
• bunx tsc --noEmit runs a full TypeScript check.

Database Notes

• drizzle/0001_extensions.sql enables pg_trgm, recreates search_vector as a generated stored column, and adds the required GIN indexes.
• drizzle/0002_better_auth.sql adds the Better Auth persistence tables: session, account, and verification.
• Search uses weighted full-text ranking over title, description, and keywords, plus trigram and substring matching over code_body.

Product Notes

• Snippet detail pages are public.
• Creating, editing, and deleting snippets requires authentication.
• Only the author of a snippet can edit or delete it.
• Search is URL-driven from the global topbar search field.
