And if you’re getting ready to build a web application that relies on GraphQL data, try out a GraphQL client library like Apollo Client it saves you time by handling the mundane parts of app development, and lets you focus on coding the parts that makes your app special. If you’re just getting started with GraphQL, I recommend using a tool like Apollo Explorer that’ll help you understand how to structure requests and explore your schema. Conclusionīecause GraphQL operates over HTTP, you can use any language, client library, or tool to fetch GraphQL data so long as you format the HTTP request properly. If you’re an iOS or Android developer, you can use the Apollo iOS and Apollo Android GraphQL clients which give you type-safe APIs to work with GraphQL servers. To learn more about Apollo Client and how to set it up in your project, check out the getting started docs. If the query successfully executes and returns the GraphQL data from the server, we can map over the response data and display the elements in a list. The last important definition is not visualized above. GraphQL Anatomy Refresher First, let’s refresh ourselves on the parts of a GraphQL Request. This article will lay out some easy-to-remember rules around the returned JSON. Passing the GraphQL query to the useQuery hook gives us an object that can be de-structured into loading, error, and data objects. Since the structure of a GraphQL query has anatomy we can expect JSON to be returned from the request in defined ways. Paste this into the Operations window and click the blue button to run the query. Here’s a query you can use to get started. To use the explorer, we’ll head to /dev and create an account (using either GitHub or your email).įinally, choose a name for your graph, select the “Development” graph type, add your localhost endpoint (Apollo Server’s default is and click “Create Graph”.Īnd that’s it! You’re ready to start querying. Getting started should be faster than making a pot of coffee. GraphQL IDEs let you build queries, browse schemas, and test out GraphQL APIs.Īpollo Explorer is a free cloud-based GraphQL IDE that comes with one-click query building, intelligent search, and a multitude of other productivity features to solve common pain-points we’ve heard from developers building apps with GraphQL. If all goes well, you should see a message letting you know that your GraphQL server is up and running. ![]() ![]() git clone ac3-state-management-examples/apollo-remote-state/server Let’s clone the repo, install the dependencies, and start the server locally. The example APIįor this post, we’ll rely on the simple todos API from apollographql/ac3-state-management-examples. ![]() So let’s demonstrate that by showing several very simple ways of calling a GraphQL API over HTTP. However, GraphQL is inherently quite simple, and works just fine without any specialized tooling. On this blog, we spend a lot of time pushing the limits of GraphQL and talking about some of the most advanced parts of the technology.
