The Art of Designing GraphQL APIs: An In-Depth Exploration

In this lesson, we'll provide a bird's eye view of the entire course, giving you a glimpse of what's in store as you embark on your GraphQL journey. We'll touch upon the key topics and concepts that will be covered in each chapter, offering a clear roadmap to guide you through this course.

Embark on your GraphQL journey, learning about its origins, core concepts, and why it's transforming the way we build APIs. Understand the benefits and use cases of GraphQL, setting the stage for your API mastery.

In this lesson, we'll introduce our demo project, the Planetary Party Planner, which will be the centerpiece of our learning experience throughout the course. By working on this project, you'll gain hands-on experience implementing features such as authentication, pagination, caching, and more, all within a practical and fun application.

Master the art of designing GraphQL schemas that define the shape of your data and set the foundation for your API. Learn how to create types, queries and mutations that work harmoniously to provide a seamless API experience.

Explore the two popular ways to build GraphQL APIs - schema-first and TypeScript-first - and choose the path that suits your project best. Gain an understanding of the benefits and drawbacks of each approach to make an informed decision.

Ensure your GraphQL API is secure, user-friendly, and resilient with proper authentication, authorization, and error handling. Learn best practices for protecting sensitive data, managing user access, and handling errors gracefully.

Delve into the world of Pothos for creating TypeScript-first GraphQL APIs, unlocking the benefits of strong typing and rapid development. Understand the advantages of using TypeScript in your GraphQL API and how Pothos streamlines the process.

Explore the various options for consuming GraphQL APIs, from simple fetch requests to powerful libraries. Gain an understanding of the trade-offs between different approaches, helping you choose the right solution for your needs

Uncover the secrets of efficient data retrieval with GraphQL pagination techniques. Learn how to implement cursor-based and offset-based pagination, providing flexible and performant solutions for clients consuming your API.

Explore real-time communication in GraphQL via subscriptions. Grasp the fundamental workings of subscriptions, and understand the power of real-time updates.
