Apollo Client is a popular library in JavaScript which is integrated with React applications to fetch and manage local and remote data with GraphQL. It is a comprehensive state management library, managing the state automatically with minimal code.

In this course, you’ll learn to integrate React applications with a GraphQL server. The course uses Apollo with React applications to query a GraphQL server. You will learn how to use the GraphQL Code Generator to generate TypeScript code that you can use in a React application to query and use GraphQL data in a standardized manner. You will learn how to generate lazy queries and use union types. By the end, you will also learn about mutations and their executions.

This course will help you gain working knowledge of data fetching, caching, and managing with the help of Apollo Client. To further your skills, you may use Apollo Client to integrate with Angular, Vue, Solid, Svelte and other JavaScript frameworks.

(True or False) GraphQL Code Generator generates two functions for a GraphQL query found in components: one lazy and one non-lazy.


(True or False) GraphQL Code Generator generates two functions for a GraphQL query found in components: one lazy and one non-lazy.

(True or False)The only difference between the generated lazy and non-lazy functions is that the lazy function calls useLazyQuery in its return statement, and the non-lazy function calls useQuery in its return statement.
