A production-grade community signup application for CoffeeHouse built in Bolt.new with client-side syntactic pre-submission validation, contextual error explanation tooltips, and guarded PostgreSQL database ingestion via Supabase.
- Decodes the core clue by prompting Bolt.new to validate inputs client-side, explain mistakes contextually, and store clean entries in Supabase
- Pixel-perfect replication of the CoffeeHouse community signup form from the challenge screenshot with warm cream aesthetic
- Contextual validation tooltip explaining exact syntactic errors, including the challenge screenshot's 'Please include an @ in the email address. example is missing an @'
- Guarded Supabase database ingestion with live table console, handling PostgreSQL unique violation 23505 gracefully
- Interactive Bolt.new IDE project tree, Prompt Engineering Lab comparing naive vs production prompts, and 5 form validation trap diagnostics
Built with: Form Validation, Supabase, PostgreSQL, Bolt.new, HTML5 Constraint Validation, Check Constraints, Vite, TypeScript, Prompt Engineering
