How to fetch only specific data from graphql query?

@adan 

To fetch only specific data from a GraphQL query, you can use the field selection feature of GraphQL. In your query, you can specify the fields that you want to retrieve by listing them after the query keyword. For example:

1
2
3
4
5
6

query {
  users {
    id
    name
  }
}

In this example, we are fetching only the id and name fields for each user. This allows you to retrieve only the specific data that you need, reducing the amount of data that is returned in the response.

You can also use aliases to rename the fields that you are fetching, making it easier to work with the data in your application. For example:

1
2
3
4
5
6

query {
  allUsers: users {
    userId: id
    fullName: name
  }
}

In this example, we are assigning aliases to the users field and the id and name fields, so that they can be accessed with different names in the response.

By using field selection and aliases, you can fetch only the specific data that you need from a GraphQL query, making your requests more efficient and reducing the amount of data that is transferred over the network.
