To filter and limit nested arrays of objects in GraphQL, you can use arguments in your resolver to pass filters and limits to your database query.
- Define arguments in your GraphQL schema:
1 2 3 |
type Query {
getObjects(filter: String, limit: Int): [Object]
}
|
- Use arguments in your resolver to filter and limit the nested arrays of objects:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
Query: {
getObjects: (_, { filter, limit }, { dataSources }) => {
let objects = dataSources.ObjectAPI.getObjects();
// Filter objects based on the filter argument
if (filter) {
objects = objects.filter(obj => obj.property === filter);
}
// Limit the number of objects returned based on the limit argument
if (limit) {
objects = objects.slice(0, limit);
}
return objects;
}
}
|
- Use the query in your GraphQL client with the desired filter and limit arguments:
1 2 3 4 5 |
query {
getObjects(filter: "value", limit: 5) {
// Query fields
}
}
|
By using arguments in your resolver function, you can dynamically filter and limit the nested arrays of objects in your GraphQL query.
