This course will teach you how to build a GraphQL API from absolute scratch. It is taught by a developer that has over 3 years of experience with GraphQL and has worked with it in multiple enterprise companies. By the end of this crash course, you will become an expert and know more than 99% of GraphQL hobbyists. This course isn't just aimed to teach you GraphQL, but how to properly utilize it in a real application. I hope you enjoy it!

We will be learning everything from scratch and thus you can be a GraphQL beginner to take this course. However, we will be using JavaScript as our primary language and thus some JS knowledge is ideal. We will also connect our server to the frontend and we will be using React as our client. Thus any frontend knowledge would be good but not unnecessary.

This course will teach you:

- What is GraphQL

- What are the benefits of GraphQL

- Learn GraphQL terminology

- How to build a GraphQL server

- Modern design principles

- Adding Authentication

- Working with Prisma v3 to interact with a Postgres DB

- Connecting GraphQL to the client

- Improve performance by learning about the n + 1 problem and solving it will data loaders
