How can I use GraphQL to fetch data efficiently?

You can use GraphQL to fetch only the data you need by specifying the fields in your query. This reduces over-fetching.

Can you show me an example of a GraphQL query?

Sure! Here's a simple query to fetch a user's name and email:

query {
  user(id: "1") {
    name
    email
  }
}

What are the benefits of using GraphQL over REST?

GraphQL allows for more flexible queries, reduces the number of requests, and provides a single endpoint for all data.

Are there any downsides to using GraphQL?

Yes, it can be more complex to set up and may lead to performance issues if not optimized properly.
