WunderGraph is a tool that brings together REST, GraphQL, and all datasources into a single, secure, typesafe, end-to-end avenue for user experiences. It acts as a Backend-for-Frontend (BFF) service layer or API gateway, consolidating data from disparate sources and providing secure JSON-RPC access to users through powerful introspection. The tool is used in conjunction with Next.js and Strapi to build an eCommerce app that decouples frontend and backend, bridging the gap between them securely. A survey found that 47% of online shoppers would pay more for an eCommerce experience exceeding expectations, highlighting the need for a seamless and secure shopping experience. WunderGraph simplifies this process by providing typesafe communication and a single source of truth for product information management.
