React query with nextjs13 app directory

Hi @fast mulch. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, it's not explicitly mentioned whether you should use React Query with Next.js 13 or not. However, there are some key points to consider:

1. Data Fetching: Next.js 13 introduces a powerful new way to fetch data and handle promises inside components. It extends the native fetch Web API, which automatically dedupes fetch requests and provides a flexible way to fetch, cache, and revalidate data at the component level. This means all the benefits of Static Site Generation (SSG), Server-Side Rendering (SSR), and Incremental Static Regeneration (ISR) are now available through one API. This could potentially replace some of the functionalities provided by React Query. source (https://nextjs.org/blog/next-13)

async function getData() {
 const res = await fetch('<https://api.example.com/...'>);
 return res.json();
}
 
export default async function Page() {
 const data = await getData();
 return <main>{/* ... */}</main>;
}

2. Server Components: When you run next build to generate a static export, Server Components consumed inside the app directory will run during the build, similar to traditional static-site generation. The resulting component will be rendered into static HTML for the initial page load and a static payload for client navigation between routes. No changes are required for your Server Components when using the static export, unless they consume dynamic server functions. source (https://nextjs.org/docs/app/building-your-application/deploying/static-exports)

export default async function Page() {
 // This fetch will run on the server during `next build`
 const res = await fetch('<https://api.example.com/...'>)
 const data = await res.json()
 
 return <main>...</main>
}

3. React Context: React Context enables components to share data without passing props down manually at every level of the component tree. This is particularly useful for data that can be considered "global" for a tree of React components, such as user authentication status or theme preferences. source (https://vercel.com/guides/react-context-state-management-nextjs)

Given these points, whether to use React Query or not depends on your specific use case. If the built-in data fetching and state management capabilities of Next.js 13 meet your requirements, you might not need React Query. However, if you have complex state management needs or require advanced features provided by React Query, it could still be beneficial to use it alongside Next.js 13.

Remember to thoroughly test your application after migrating to ensure everything works as expected.

@fast mulch kapa.ai is still learning and improving, please let us know how it did by reacting below

@tulip horizon So should i use react query with axios? Or its better to use nextjs functions to fetch? Im able to use query keys in nextjs as i can do it in react query?

Let me check the knowledge base for you. One moment! :books:

Based on the information provided in the extracts, Next.js 13 has introduced a simplified data fetching mechanism with async/await in Server Components, and an extended fetch API for request memoization, data caching, and revalidation. This could potentially replace the need for using Axios with React Query for data fetching. source (https://nextjs.org/docs/app/building-your-application/data-fetching)

export default async function Page() {
 const [staticData, dynamicData, revalidatedData] = await Promise.all([
 // Cached until manually invalidated
 fetch(`<https://...`>),
 // Refetched on every request
 fetch(`<https://...`,> { cache: 'no-store' }),
 // Cached with a lifetime of 10 seconds
 fetch(`<https://...`,> { next: { revalidate: 10 } }),
 ]);
 
 return <div>...</div>;
}

However, the decision to use React Query with Axios or Next.js functions for data fetching depends on your specific use case and requirements. If you have complex state management needs or require advanced features provided by React Query, it could still be beneficial to use it alongside Next.js 13.

As for query keys, the extracts do not provide specific information on whether Next.js supports a similar concept. React Query's query keys are a powerful feature for managing cache invalidation and updates, but it's unclear if Next.js has a direct equivalent. You might need to manage this manually with Next.js's caching mechanisms. source (https://nextjs.org/docs/app/building-your-application/caching)
