How to handle data fetching with React Suspense

Handling Data Fetching with React Suspense

Introduction

• React Suspense is a tool that simplifies asynchronous operations like data fetching in React applications.
• It allows components to temporarily suspend rendering while waiting for asynchronous data and display a fallback UI.

How React Suspense Works

• React Suspense renders a fallback UI while waiting for an asynchronous operation to complete.
• The fallback property determines what is rendered during the loading phase.
• It enables render-as-you-fetch behavior, starting rendering immediately after a network request is triggered.

React Data Fetching Patterns

• Fetch-then-render approach: Fetching data before rendering the component to ensure it's available.
• React Suspense supports render-as-you-fetch, enhancing performance.
• React Query provides advanced features like caching and retries for API data fetching.

Using React Query with React Suspense

• Install React Query as a dependency in a React application.
• Fetch data using React Query and React Suspense for improved data fetching and UI responsiveness.

Using React Suspense with React

• React.lazy is used for dynamically loading components for optimized performance.
• Wrap components with React Suspense to manage loading states efficiently.

Example

• Create a component that fetches user data and renders user details using React and React Suspense.
• Similarly, create a Todos component to fetch and display a to-do list using the same approach.

Conclusion

• React Suspense simplifies data fetching in React applications by allowing components to suspend rendering during asynchronous operations.
• By integrating React Suspense with React Query and React.lazy, developers can enhance data fetching efficiency and optimize user experience.
