Apollo Server is an open-source GraphQL server that works with any GraphQL schema. Apollo Server 5 is framework-agnostic and runs standalone or integrates with Express, Fastify, and serverless environments. For Express integration: Standalone (Recommended for prototyping): The standalone server is great for prototyping, but for production services, we recommend integrating Apollo Server with a more fully-featured web framework such as Express, Koa, or Fastify. Swapping from the standalone server to a web framework later is straightforward. Express: Resolvers follow the signature: (parent, args, contextValue, info) Context is created per-request and passed to all resolvers.
