How abhinav7682/lambda works
Lambda is a small e-commerce storefront with a browser UI, Express API, and SQLite product inventory. The shopper browses products, adds items to a cart, and submits checkout; the API validates stock and updates it transactionally. The frontend also supports mock product data, but the sampled code does not show enough checkout details to map its precise UI states or request payload construction. The README provides no further product capabilities.
