GraphQL Apollo-Client Workshop

By Khriztian Moreno

Made with Slides.com

GraphQL Apollo-Client Workshop

GraphQL is a fan favorite for good reason. It lets a client make specific, complex, and/or aggregate queries for data, and it’s user-friendly to boot. If you’ve been meaning to learn GraphQL and start harnessing its powers, this is a great place to start. This course is for GraphQL newbies with a basic understanding of React. It focuses on the client-side implementation of GraphQL usage using the Apollo client. We’ll start with a guide on how to add the Apollo client to an existing project, then move on using the Query and Mutation components to fetch and manipulate data using a GraphQL API.
