Apollo CLI

Apollo CLI is a command-line tool for GraphQL projects. It validates a service's schema, lints client operations for compatibility with that schema, and generates static types to improve type safety on the client side.

Commands are organized under a client namespace, for checking a schema, downloading it, extracting operations and pushing changes, and a service namespace for managing a registered schema.

The project's own documentation notes that most of its functionality has been replaced by newer Apollo projects, in particular Rover, and that its code generation commands are no longer supported in favor of graphql-code-generator; support for the remaining tooling is described as minimal.
