GraphQL Middleware lets you run arbitrary code before or after a resolver is invoked. It improves your code structure by enabling code reuse and a clear separation of concerns.

Middleware keeps resolvers clean

A well-organized codebase is key for the ability to maintain and easily introduce changes into an app. Figuring out the right structure for your code remains a continuous challenge - especially as an application grows and more developers are joining a project.

A common problem in GraphQL servers is that resolvers often get cluttered with business logic, making the entire resolver system harder to understand and maintain.

GraphQL Middleware uses the middleware pattern well-known from Express.js to pull out repetitive code from resolvers and execute it before or after one your resolvers is invoked. This improves code modularity and keeps your resolvers clean and simple.
