Скачать или смотреть Intro to Data Loaders in GraphQL | Solve the N+1 Problem with NodeJS (#03) | 🟢 Beginner Level

In this video, we explore the N+1 query problem in GraphQL and how to solve it with Data Loaders in a Node.js + TypeScript setup.
We also build our first batch loader using real data from the JSONPlaceholder API.

🔧 Note: It’s a good idea to pass your data loaders via GraphQL context (something I forgot in the video!)
