How to Handle State in Apollo React: A Comprehensive Guide
Have you ever found yourself struggling with handling state in Apollo React applications? You're not alone. Whether you are a seasoned developer or just starting with GraphQL and Apollo Client, managing state effectively can be a challenging task. In this article, we will explore different strategies and best practices to help you tackle this common issue.
Understanding the Challenge of State Management in Apollo React
Before we dive into the solutions, let's first understand why state management in Apollo React can be tricky. Apollo Client is a powerful tool for managing data in GraphQL applications, but it focuses primarily on handling remote data from a GraphQL server. When it comes to managing local state within your React components, things can get a bit more complex.
In a typical React application, you might use tools like React's built-in useState or useReducer hooks to manage local component state. However, when you introduce Apollo Client into the mix, you might wonder how to best integrate it with your existing state management approach.
Solution 1: Using Apollo Client's useQuery and useMutation Hooks
One of the simplest ways to handle local state in Apollo React is to leverage Apollo Client's useQuery and useMutation hooks. These hooks allow you to fetch data from your GraphQL server and perform mutations while automatically managing the loading and error states for you.

By using these hooks, you can keep your component logic clean and concise, delegating the heavy lifting of data fetching and mutations to Apollo Client.
Solution 2: Leveraging Apollo Client's useReactiveVar for Local Reactive Variables
Sometimes you might need to manage local reactive variables that are not directly related to data fetched from your server. In such cases, you can use Apollo Client's useReactiveVar hook in conjunction with Apollo Client's makeVar function to create and update local reactive variables.
Jsx
This approach is particularly useful when you need to share state between multiple components without the need for complex prop drilling.
Solution 3: Context API and Apollo Client: A Powerful Combination
Another effective way to handle state in Apollo React is by combining Apollo Client with React's Context API. By creating a context that wraps your Apollo Client instance, you can easily access your Apollo Client instance and manage state across your application.
Jsx
By utilizing React's Context API in conjunction with Apollo Client, you can centralize your state management and make it accessible throughout your application.
In this article, we've explored various strategies for handling state in Apollo React applications. By leveraging Apollo Client's hooks, reactive variables, and the Context API, you can effectively manage state in your components without compromising the power and flexibility of GraphQL data fetching.
With these approaches in your toolkit, you can confidently build robust and scalable applications using Apollo Client and React. Experiment with these techniques in your projects and discover the optimal way to handle state in your Apollo React applications.
