How to handle versioning while deploying a GraphQL server to production?

There are multiple approaches to handle versioning while deploying a GraphQL server to production. Here are a few commonly used methods:

  1. URL Versioning: In this approach, you can include the version number in the URL itself. For example, instead of accessing /graphql, you could access /v1/graphql or /v2/graphql. This allows you to have different versions of your GraphQL server running concurrently and allows clients to explicitly request a specific version.
  2. Request Header Versioning: Another way to handle versioning is by using custom request headers. Clients can include a header like Accept-Version or GraphQL-Version in their requests, indicating the version they require. The server can then interpret and process the request accordingly.
  3. Field/Type Level Versioning: You can introduce versioning at the field or type level within your GraphQL schema. By annotating certain fields or types with version information, you can ensure compatibility for clients using different versions. This approach enables you to make changes and deprecations to fields/types while still maintaining backward compatibility.
  4. Deprecated Fields: When making changes to the GraphQL schema that might affect existing clients, you can mark certain fields as deprecated and provide alternative fields or types. This allows you to introduce new versions while providing a migration path for clients.
  5. API Changelog: Maintain a well-documented changelog for your API, indicating the changes made in each version. This helps clients who want to update their integration with your GraphQL server and allows them to adapt to new features or changes.

It's important to choose a versioning strategy based on your specific use case and compatibility requirements. Additionally, communication and documentation for clients about versioning changes are crucial to ensure a smooth transition and minimize disruptions.
