Apollo CLI

Apollo CLI (v2.34.0) is a command-line tool for Apollo GraphQL that validates schemas, lints operations for compatibility, generates TypeScript/Flow/Swift types, and pushes client-side operations to Apollo Studio. It supports service and client operations like schema download, push, check, and codegen. Release cadence is irregular; development is winding down. Key differentiators include tight integration with Apollo Platform, deep federation support, and built-in type generation. As of Jan 2022, the tool is slated for deprecation—most functionality is being replaced by Rover and Apollo's VSCode extension.
