You can and should have multiple context providers for different state that. React Context is a powerful feature in React that allows you to share data between components without having to pass it through props. As a quick reminder, applying the React context requires 3 actors: the context, the provider extracted from the context, and the consumer. React React with APIs Context Best Practices, Alternatives, and Further. These values are then saved in the context. Let's see how to apply it in the next section. It uses the useQuery hook from the Apollo Client to execute the query and get the query data, loading, and error values. The component takes in a query which is a GraphQL query, and optionally variables which is passed to the query. React gives us the ability to do both of those things whenever we create a new Context using the React.createContext method. The QueryResultProvider component is used to wrap a component tree, providing it with the context for a specific GraphQL query. To help show how to avoid props-drilling, we'll first configure two components to use React Context: QueryResultProvider and useQueryResult. I am wondering whether this really increases the performance or can lead to reduced render cycles. What is useContext in React The useContext hook is a built-in hook in React that allows you to consume data from a context provider. Instead our data will be accessible through a React Hook, which can be called anywhere in the nested component tree. Some blog articles split up the context into two seperate update and state context when working with React Context. Props-drilling can cause problems when you need to rename a property or update the data type and can cause bloat within your application as each component in the tree needs to be aware of properties they may not be using. React Context provides a way to pass data through the component tree without having to pass props down manually at every level in your application which is also known as props-drilling.
