How to fetch data from an API using GraphQL in a React App Of course everyone is familiar with REST APIs, but there is another type of API that is becoming increasingly popular and that is the GraphQL API. GraphQL is a data query language for APIs. The significant difference between GraphQL APIs and REST APIs is that in a GraphQL API, we explicitly indicate in our query which specific data we want to fetch and request. In a REST API, we get back all the data from a url endpoint. Thus, GraphQL saves us some time by giving us more control over which data we want to request and receive from the API. The first time I encountered GraphQL was when I was learning how to create a Gatsby.js app; it uses GraphQL to access your app data. I’ve also attended a workshop where I learned how to build a GraphQL API using MongoDB and Node.js. Naturally, the next logical step in my GraphQL expedition would be to use GraphQL with a frontend library like, React. In this blog, ...
Intro This page will walk you through a series of GraphQL queries, each designed to demonstrate a particular feature of GraphQL. These examples will work on the real schema used on graphql-reference example . You can run this example locally to experiment and poke around the innards of the site! To get to the GraphiQL editor, go to localhost:8000/___graphql (that’s three underscores). You can also open the CodeSandbox version of the example site. For more background information, read about why Gatsby uses GraphQL and how to use GraphiQL in any Gatsby site. Basic queries Example: Site metadata Start with the basics, pulling up the site title from your gatsby-config.js ’s siteMetadata . Copy copy code to clipboard { site { siteMetadata { title } } } In the GraphiQL editor, try editing the query to include the description from siteMetadata . When typing in th...

So, I thought I would start writing down the stuff I know well, to help me remember what I know, and for a reference for others. To this end, I’m starting with something simple, a Node app that responds to a request with a static file. Or, at least this is something that among experienced developers might seem simple, but I’m going to be a little bit verbose with this, because I’d like for someone with bare minimum web development knowledge to be able to at least get started with this Node app and come away from this tutorial with a solid foundation for the fun stuff that comes next. Still, I can’t explain everything, so somet...
