Apollo HTTP Link with DataLoader Batching

http-link-dataloader is an Apollo Link designed to provide efficient HTTP requests for GraphQL by leveraging Facebook's DataLoader for automatic batching and caching. It distinguishes itself from `apollo-link-batch-http` by using an event-loop-based batching mechanism, consolidating consecutive GraphQL queries into a single HTTP request payload. The package currently sits at version 0.1.6, with its last release in 2018, indicating a lack of active development or a very slow release cadence. It was primarily developed for use cases involving `graphql-yoga` servers and `prisma-binding` (now largely deprecated in favor of Prisma Client), supporting array-based GraphQL batching on the server side. It ships with TypeScript types, but its age raises significant compatibility concerns with modern Apollo Client (v3+) and GraphQL ecosystems.
