How do I paginate results with graphql-go in Go?

Pagination is a common requirement when dealing with large sets of data in GraphQL. With the graphql-go library, you can implement pagination in a structured way. The most common techniques for pagination include cursor-based and offset-based pagination. Below, I'll explain both methods and provide an example to demonstrate how to paginate results using graphql-go.

// Sample Go code demonstrating pagination with graphql-go package main import ( "context" "fmt" "github.com/graphql-go/graphql" "net/http" "github.com/graphql-go/handler" ) type Item struct { ID int `json:"id"` Name string `json:"name"` Description string `json:"description"` } var items []Item func init() { for i := 1; i <= 100; i++ { items = append(items, Item{ID: i, Name: fmt.Sprintf("Item %d", i), Description: fmt.Sprintf("Description for Item %d", i)}) } } func getPaginatedItems(offset int, limit int) []Item { start := offset end := offset + limit if start >= len(items) { return []Item{} } if end > len(items) { end = len(items) } return items[start:end] } func main() { itemType := graphql.NewObject(graphql.ObjectConfig{ Name: "Item", Fields: graphql.Fields{ "id": &graphql.Field{Type: graphql.Int}, "name": &graphql.Field{Type: graphql.String}, "description": &graphql.Field{Type: graphql.String}, }, }) queryType := graphql.NewObject(graphql.ObjectConfig{ Name: "Query", Fields: graphql.Fields{ "items": &graphql.Field{ Type: graphql.NewList(itemType), Args: graphql.FieldConfigArgument{ "offset": &graphql.ArgumentConfig{ Type: graphql.Int, }, "limit": &graphql.ArgumentConfig{ Type: graphql.Int, }, }, Resolve: func(p graphql.ResolveParams) (interface{}, error) { offset, _ := p.Args["offset"].(int) limit, _ := p.Args["limit"].(int) return getPaginatedItems(offset, limit), nil }, }, }, }) schema, _ := graphql.NewSchema(graphql.SchemaConfig{ Query: queryType, }) h := handler.New(&handler.Config{ Schema: &schema, GraphiQL: true, }) http.Handle("/graphql", h) http.ListenAndServe(":8080", nil) }
