Object Fields
- Object Field are a bit complex as they are used to represent data types which have their own set of fields.
- In Object fields you can traverse related data structure. Nesting is also allowed in Object Fields.
- You can understand Object fields better by understanding the below example.
type Article{
id: ID!
title: String!
author: Author!
}
type Author{
id:ID!
name: String!
email: String!
}
Explanation:
- In this, example the above there are two objects Article and Author.
- The object Article, has three fields: `id`,`title`,`author`.
- The `id` field is of type `ID` and the `title` field is of type `String` both the fields are marked with exclamation mark representing that they are required field.
- The third field of the object Article is of Object type, it is also a required and should not be null value. The `article` field represent a relationship to another object.
- The `author` object has three fields: `id`, `name`,`email`.
- Similar to the `Article` object the id` field is of type `ID` and the `name` field is of type `String` both the fields are marked with exclamation mark representing that they are required field.
- The `email` field of the `Author` object is marked required.
- As there is an relationship between the `Article` object and `Author` object, hence this schema allows the clients to query for articles and retrieve information about their author in a structured manner.
Fields in GraphQL
Fields in GraphQL are the fundamental components that allow clients to specify the data they need from a server. They represent individual pieces of data that can be requested for an object. Understanding how fields work is essential for building efficient GraphQL queries and designing effective schemas.
