How to split a long graphql schema?

Splitting a long GraphQL schema can help improve maintainability, readability, and organization of your code. Here are some strategies you can use to split a long GraphQL schema:

1. Use modularization: Break up your schema into smaller, manageable modules based on logical groupings. For example, you can have separate schema files for different types of data (e.g. users, posts, comments) or functionality (e.g. authentication, notifications).
2. Use fragments: Define reusable fragments for common fields or types in your schema. This can help reduce duplication and make your schema more concise and easier to understand.
3. Use interfaces and unions: Utilize interfaces and unions to define shared fields and types across multiple object types. This can help reduce redundancy and make your schema more organized.
4. Use schema stitching: If you have multiple microservices with their own GraphQL schemas, you can use schema stitching to combine them into a single, composite schema. This can help you manage a complex schema by breaking it down into smaller, more manageable parts.
5. Use extensions: Extend existing types and fields in your schema to add new functionality without cluttering the main schema file. This can help keep your schema modular and organized.
6. Use comments and documentation: Include comments and documentation in your schema to provide context and explanations for each type, field, and directive. This can help other developers understand the schema structure and functionality.

By following these strategies, you can effectively split a long GraphQL schema into smaller, more manageable parts, making it easier to maintain and work with in the long run.
