Course Summary
GraphQL is a query language, specification, and collection of tools designed to offer a more performant and flexible alternative to Representational State Transfer (REST), a common standard for executing Hyper Text Transfer Protocol (HTTP) requests. The Relay & GraphQL course teaches developers to use Relay with GraphQL in the context of React applications.
The course begins with lectures and exercises on making GraphQL requests and understanding Relay concepts like fragments, variables, and callbacks. It then transitions to cover Relay concepts like slicing, pagination, and data fetching. Finally, it concludes with a deep dive into Relay mutations, including working with optimistic updates and fat queries. The course would be helpful for developers and developer teams who want to learn an alternative way to query and fetch data.
- Productivity Objectives:
- Explain the problems that GraphQL and Relay help to solve.
- Write GraphQL queries to retrieve data from a database.
- Build out a client UI that specifies its data needs using Relay to connect to your GraphQL-based server.
