SnippetVault
Create, organize, and share code snippets — with authorization enforced in the database, not the app.
Overview
A snippet manager and sharer. Store your code collections, manage them from a dashboard, and share publicly — with syntax highlighting and snippet-to-image export.

Problem
Code snippets scatter across gists, notes, and DMs. And most apps trust the client for authorization, which leaks data the moment a check is missed.
Approach
- 01
Delegate authorization to Postgres row-level security so the database — not app code — is the source of truth.
- 02
Isolate all Supabase calls inside a thin API layer (src/lib/api/*) to minimize vendor lock-in.
- 03
Optimistic UI updates via TanStack Query for instant-feeling edits.
- 04
Syntax highlighting and snippet-to-image export for sharing.
Outcome
- Authorization that can't be bypassed from the client — enforced at the row level.
- Snappy dashboard with optimistic updates and server-state caching.
- Deployed on Vercel with full auth flows.
