What is Fetching?
- In GraphQL, fetching refers to the process of retrieving data from a server or database.
- Unlike REST APIs, GraphQL allows clients to request only the data they need, reducing over-fetching.
- Clients can specify nested fields in their queries to fetch related data in a single request.
- GraphQL responses contain only the data requested, making data transfer more efficient.
- GraphQL can fetch data from multiple sources in a single query, reducing the number of round trips to the server.
What Are Over-Fetching and Under-Fetching?
Fetching data in GraphQL is a fundamental concept that involves retrieving information from a server or database. Unlike traditional REST APIs, GraphQL allows clients to request only the specific data they need, minimizing over–fetching and under–fetching.
In this article, We will explore the concepts of fetching, over–fetching, and under–fetching in GraphQL, along with their challenges and solutions in detail and so on.
