To send an array of objects with a GraphQL mutation, you can define a custom input type in your schema that represents the array of objects. Here's an example of how you could achieve this:
- Define the custom input type in your GraphQL schema:
1 2 3 4 5 6 7 8 9 |
input ObjectInput {
id: ID!
name: String!
// Add any other fields needed for the object
}
input ArrayOfObjectsInput {
objects: [ObjectInput!]!
}
|
- Use the custom input type in your mutation:
1 2 3 |
type Mutation {
createObjects(objects: ArrayOfObjectsInput!): [Object!]!
}
|
- Sample query to send array of objects:
1 2 3 4 5 6 7 8 9 10 11 12 |
mutation {
createObjects(objects: {
objects: [
{ id: "1", name: "Object 1" },
{ id: "2", name: "Object 2" },
{ id: "3", name: "Object 3" }
]
}) {
id
name
}
}
|
- Handle the array of objects in the resolver of the mutation:
1 2 3 4 5 6 7 8 9 |
Mutation: {
createObjects: (_, { objects }) => {
// Loop through the array of objects and create new objects in the database
return objects.map(object => {
// Create object in the database and return it
return createObject(object);
});
}
}
|
By following these steps, you can send an array of objects with a GraphQL mutation and process them in your server-side application.
