What are the best practices for writing GraphQL queries?

When writing GraphQL queries, consider the following best practices: 1. Use fragments to avoid duplication. 2. Keep queries concise and focused. 3. Avoid over-fetching by requesting only the fields you need. 4. Use variables for dynamic values. 5. Implement pagination for large datasets.

Can you explain why avoiding over-fetching is important?

Avoiding over-fetching is crucial because it reduces the amount of data transferred over the network, improving performance and efficiency. It also minimizes the load on the server and enhances the user experience by speeding up response times.

What are fragments and how do they help?

Fragments are reusable units of a GraphQL query that allow you to define a set of fields that can be included in multiple queries. They help keep your queries DRY (Don't Repeat Yourself) and make your code cleaner and easier to maintain.

How can I implement pagination in my queries?

You can implement pagination in GraphQL by using arguments like 'limit' and 'offset' or by using cursor-based pagination. This allows you to fetch a subset of results and load more as needed, which is especially useful for large datasets.
