Slicing Quickly, though, we realize that there are additional behaviors a client might want. A client might want to be able to specify how many friends they want to fetch—maybe they only want the first two. So we’d want to expose something like this: But if we just fetched the first two, we might want to paginate through the list as well; once the client fetches the first two friends, they might w

This specification aims to provide an option for GraphQL clients to consistently handle pagination best practices with support for related metadata via a GraphQL server. This spec proposes calling this pattern “Connections” and exposing them in a standardized way. In the query, the connection model provides a standard mechanism for slicing and paginating the result set. In the response, the connec
Why Pagination In this post, I'm going to show how you can get started with pagination in GraphQL using an AWS AppSync API and the AWS Amplify framework. The primary reason to use pagination is to control and limit the amount of data that is fetched from your backend and returned to your client at once. Pagination can help build efficient and cost-effective solutions by controlling the amount of w
Photo by Gaspar Uhas on UnsplashFacebook’s developer page said it best: “Cursor-based pagination is the most efficient method of paging and should always be used where possible.” So what exactly is pagination? Pagination is the process of separating data into sets. Just like the pages of a book. There are two main ways to implement pagination on a website. But which one is better? Let’s explore bo
Pagination is a technique for breaking large record sets into smaller portions called pages. As a developer, you should be familiar with implementing pagination, but implementing pagination for real time data can become tricky even for experienced developers. In this tutorial, we are going to discuss the practical use cases and solutions for real time data pagination and cursor based pagination. K
メディア開発部の今村です. 最近はグノシーの社内管理画面のリプレイスをしており, Next.js / Go / GraphQL / MySQLという構成で新しい管理画面を作っています. 開発の途中で, 記事検索機能のページネーションを実装する機会がありました. GraphQLサーバーのページネーションについては, RelayというGraphQLクライアントライブラリが要求しているCursor Connectionsという仕様が有名です. 今回はこの仕様を参考にしたのですが, 読めばすぐに意義や実装方法が分かるというものでもなく, 解説記事を読みながら手探りで実装を進めることになりました. そこで, この記事では, Cursor Connectionsの仕様, メリットやGoとRDBを使う場合の実装について説明します. Cursor Connectionsとは オフセットページネーション カ
