The Core Concepts of GraphQL

Welcome to our comprehensive GraphQL course, where we'll embark on a journey to explore the world of efficient and flexible APIs. Throughout this course, we'll cover various aspects of GraphQL, from its core concepts to building, deploying, and consuming GraphQL APIs. Additionally, we'll delve into advanced topics such as pagination, authentication, caching, and real-time updates and discuss when not to use GraphQL and the best practices to follow.

Our adventure begins with an introduction to GraphQL, where you'll get acquainted with its brief history and learn how it compares to traditional REST APIs. We'll then dive into the core concepts of GraphQL, helping you understand the intricacies of GraphQL queries, mutations, and subscriptions, as well as how to tie everything together with schema and resolvers.

The course is structured to balance theoretical knowledge and practical application. To ensure a well-rounded learning experience, we'll work on a fun and engaging project - Planetary Party Planner. This hands-on project is designed to include the nuisances of a real-world GraphQL API. We will explain intricate concepts in GraphQL across different chapters taking examples from building the project.

Once we are comfortable with the core concepts of GraphQL, we will focus on how to build large GraphQL APIs — detailing different approaches such as Schema-first and TypeScript-first. We also discuss the many options to deploy GraphQL APIs — from servers in edges to completely serverless ways.
