Keep your friends close and your APIs closer
summary
Introduces the Backend For Frontend pattern applied to microfrontends and shows a production setup that uses Next.js API routes and server components to avoid extra client network hops. Describes using Podium to assemble small apps into pages, cites a real settings page built from ~8 microfrontends, and explains tradeoffs: front-end teams gain independence, different protocols (tRPC, GraphQL, protobuf) are possible, API keys are hidden, but requests and code are duplicated and BFFs become a single point of failure.
