Using axios as a GraphQL client

Interacting with a GraphQL server is done via HTTP. We learned in Chapter 9, Interacting with Restful APIs, that axios is a great HTTP client. So, in this chapter, we'll cover how to interact with a GraphQL server using axios.

To help us learn, we'll create a React and TypeScript app to return information about our GitHub account. So, our first tasks are to get a token that will give us access to query the GitHub GraphQL server and scaffold a React and TypeScript app.

Getting a GitHub personal access token

The GitHub GraphQL server requires a bearer token for us to interact with it. So, let's go and generate a personal access token:

  1. Let's sign in to our GitHub account and...
