The concept of children as a function or child as a function , also called render prop in general, is one of the advanced patterns in React (next to higher-order components ). The components which implement this pattern could be called render prop components. In this tutorial, you will learn everything about React's render prop pattern…

Newcomers to React often start with applications that don't need data fetching at all. Usually they are confronted with simple applications. That's good, because data fetching adds another layer of complexity to your application while taking the first steps in React. However, at some point you want to request real world data from an own or a third…

Finding the right solution for a given problem is not always simple, and web applications build with GraphQL are a good example of how changing times make for constantly evolving challenges. Moreover, evolving challenges create a scenario where the solutions must also evolve, so even the number of choices becomes a task. This article will decipher…

When it comes to network requests between client and server applications, REST is one of the most popular choices to connect both worlds. In REST, everything evolves around the idea of having resources that are accessible by URLs. You can read a resource with a HTTP GET request, create a resource with a HTTP POST request, and update or delete it…

In a previous application, you have used Apollo Link State to substitute React's local state management with it. Even though it wasn't necessary, because it is most often sufficient to manage local state with React only, it has shown you how it can be achieved with local queries and local mutations when using Apollo Link State. However, it needs to…

When you get started with Git, it can be quite overwhelming. First, the idea of a distributed version control system and the benefits of it are not clear for everyone. And second, there are plenty of commands with additional options in order to master Git on the command line. It can be intimidating. However, you will never need all the combinations…

You may have used a GraphQL client library that was view-layer agnostic and thus able to work with React or other solutions like Angular or Vue. Other GraphQL client libraries like Relay and Urql aren't so powerful, because they are used only for React. The next chapter is to illustrate how to implement a GraphQL client library that works with…

Step-by-step is often the easiest way to learn something new, so it's fortunate that learning GraphQL in JavaScript teaches both the client and the server-side of an application. Seeing both sides of the web transactions is useful, but the catch is you have to learn two environments. The step-by-step mentality can be difficult to apply here, so I…

It's time to get you started with a minimal Apollo Client in React application that can be used as boilerplate project. There will be sections later on where you can use this application as starter project, but also you may want to experiment with it on your own. After all, it gives you all the necessary parts to consume GitHub's GraphQL API in…
