Cosmo an Open Source GraphQL Federation Platform

Introduction

GraphQL has emerged as a revolutionary data query language, providing a more efficient, powerful, and flexible alternative to the traditional REST API. It is in this vibrant landscape that WunderGraph has carved out a niche for itself, championing the cause of seamless integration through its innovative solutions.

Understanding the Basics

What is GraphQL?

At its core, GraphQL is a query language for your API, and a server-side runtime for executing queries by specifying the types and fields you want. Imagine being able to retrieve all the data you need with a single API call — this is the power of GraphQL APIs.
