Cursor Pagination

Cursor Pagination Overview

At its core, cursor pagination is about doing one thing well inside your GraphQL project. Once you understand the pattern, you can apply it consistently across features and teams.

Good cursor pagination pays off across the whole codebase: fewer surprises, easier testing, and smoother onboarding. The snippet below is a solid starting point.

query GetUser($id: ID!) {
  user(id: $id) {
    id
    name
    posts(first: 10) {
      id
      title
    }
  }
}

Clients request exactly the fields they need, passing arguments through typed variables.

Cursor Pagination Example

const typeDefs = gql`
  type Query { hello: String! }
`;
const resolvers = { Query: { hello: () => 'world' } };
const server = new ApolloServer({ typeDefs, resolvers });

• Start from a minimal Cursor Pagination example and grow it only as needed.
• Keep configuration explicit so Cursor Pagination behaves the same in every environment.
• Name things clearly so teammates understand your Cursor Pagination at a glance.
• Add tests around Cursor Pagination early to lock in expected behaviour.

How Cursor Pagination Works in GraphQL

Cursor Pagination fits into GraphQL's model of a single typed schema that clients query for exactly the data they need. The server resolves each requested field through resolver functions.

Clients request exactly the fields they need, passing arguments through typed variables.

• The schema is the contract between client and server.
• Resolvers fetch data field by field, including nested types.
• Clients request only the fields they use, avoiding over-fetching.
• Context carries auth and shared services into every resolver.

Practical Guidance for Cursor Pagination

In production, cursor pagination should be efficient and secure. Batch data access with DataLoader, guard resolvers with authorization, and limit query depth and complexity.

Common Mistakes

• Skipping error handling and edge cases when wiring up cursor pagination.
• Leaving cursor pagination untested, so regressions slip into production.
• Over-engineering cursor pagination before you actually need the extra flexibility.
• Ignoring documentation, which makes cursor pagination hard for the next developer to change.

Key Takeaways

• Cursor Pagination is a core part of working effectively with GraphQL.
• Start small and keep cursor pagination focused on a single responsibility.
• Apply consistent patterns so cursor pagination scales across your project.
• Test and document cursor pagination to keep it maintainable over time.
