In GraphQL, you can use nested types and queries to group nested data. Here's an example of how you can group nested data in GraphQL:
- Define nested types in your GraphQL schema:
1 2 3 4 5 6 7 8 9 10 11 |
type Author {
id: ID!
name: String!
posts: [Post]
}
type Post {
id: ID!
title: String!
content: String!
}
|
- Create queries to retrieve nested data:
1 2 3 4 |
type Query {
author(id: ID!): Author
post(id: ID!): Post
}
|
- Implement resolvers for the queries:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
const resolvers = {
Query: {
author: (parent, args, context, info) => {
// Query author data from database
},
post: (parent, args, context, info) => {
// Query post data from database
}
},
Author: {
posts: (parent, args, context, info) => {
// Query posts by author ID from database
}
}
}
|
- Use the queries to fetch nested data in your GraphQL client:
1 2 3 4 5 6 7 8 9 10 11 |
query {
author(id: "1") {
id
name
posts {
id
title
content
}
}
}
|
This query will return the author with ID 1 along with all the posts written by that author.
By defining nested types and queries in your GraphQL schema and implementing resolvers for these queries, you can easily group nested data in GraphQL.
