Apollo Federation

What it does

This skill enables AI agents to interact with Apollo Federation, a distributed GraphQL architecture that allows multiple microservices to compose a unified data source. It facilitates seamless querying across independent services while maintaining a single entry point for clients.

When to use it

• Building scalable backend systems where data is split across multiple microservices.
• Creating a single GraphQL gateway to aggregate data from diverse sources without exposing internal service details.
• Managing complex queries that require joining data from different domains or databases.
• Implementing centralized schema management and security policies for distributed applications.

Key capabilities

• Distributed query composition across microservices
• Unified GraphQL gateway implementation
• Automatic type propagation between services
• Centralized schema stitching and validation
• Enhanced security through isolated service boundaries

Example prompts

• "Configure an Apollo Federation gateway to aggregate user data from the authentication service and order data from the inventory service."
• "Generate a federated schema definition that exposes product details while hiding internal database structures from external clients."
• "Set up type propagation rules so that changes in the core service automatically update the types available at the gateway."

Tips & gotchas

Ensure all microservices are properly configured with unique IDs and compatible versions to avoid schema conflicts during composition. Limit direct access to individual services through the gateway to maintain security boundaries and prevent unauthorized data exposure.
