React Query Proof of Concept

Introduction

React Query is a powerful library for managing server-state in React applications. It simplifies data fetching, caching, synchronization, and updating, allowing developers to focus on building feature-rich user interfaces.

This Proof of Concept (POC) demonstrates key use cases and best practices of React Query, including querying, mutations, pagination, and infinite scroll.

Integration Guide

To start using React Query, install the required packages:

npm install react-query axios

Set up React Query Provider (for a Next.js app we need to create a wrapper component):

/components/provider/query-provider.tsx

"use client";

import { useState } from "react";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";

const QueryProvider = ({ children }: { children: React.ReactNode }) => {
  const [queryClient] = useState(() => new QueryClient());
  return (
    <QueryClientProvider client={queryClient}>{children}</QueryClientProvider>
  );
};

export default QueryProvider;

Now wrap it around the root layout of the app:

import QueryProvider from "@/components/provider/query-provider";

export default function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang="en">
      <body>
        <QueryProvider>
          {children}
        </QueryProvider>
      </body>
    </html>
  );
}
