Hasura, Apollo Server, and Prisma 2 are distinct tools that serve different purposes in application development, and they can be complementary rather than alternative solutions. Hasura is a web service that connects to data sources and exposes them through a GraphQL or REST API, with capabilities for federating APIs and enforcing configurable authorization layers. Apollo Server is a Node.js framework for creating custom GraphQL servers, allowing developers to define schemas and resolvers for various operations, such as processing payments or handling authentication. Prisma 2 functions as an ORM library, providing a bridge between Node.js applications and databases, enabling developers to write database queries within their business logic. These tools can be integrated within a development stack, such as using Hasura's Remote Schema feature to connect with Apollo Server or incorporating Prisma within an Express.js API, thereby enhancing the flexibility and functionality of the overall system.
