What are Apollo Client fragments and how do I use them?

Apollo Client fragments are reusable units of GraphQL queries that allow you to define parts of your query separately. You can use them to avoid repetition and keep your queries organized.

Can you give me an example of how to define a fragment?

Sure! You can define a fragment like this: fragment UserDetails on User { id name email }. Then, you can include it in your query: query { users { ...UserDetails } }.

How do fragments help with performance?

Fragments help with performance by reducing the size of your queries and ensuring that only the necessary data is fetched, which can lead to faster responses.

Are there any limitations to using fragments?

Yes, fragments can only be used with types that are defined in your GraphQL schema, and they cannot be used to fetch data from different types in a single query.
