Top 10 Libraries Every React Developer Should Know

Explore the most important React libraries that will help you build better applications in 2025. Let's dive into the tools that every React developer should have in their toolkit. 🚀

1. React Query 🔄

Perfect for managing server state and caching.

import { useQuery, useMutation } from '@tanstack/react-query';

function TodoList() {
  const { data, isLoading } = useQuery({
    queryKey: ['todos'],
    queryFn: fetchTodos
  });

  const mutation = useMutation({
    mutationFn: addTodo,
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['todos'] });
    }
  });

  if (isLoading) return 'Loading...';

  return (
    <div>
      {data.map(todo => (
        <TodoItem key={todo.id} todo={todo} />
      ))}
      <button onClick={() => mutation.mutate(newTodo)}>
        Add Todo
      </button>
    </div>
  );
}

2. Zustand 🐻

Lightweight state management with a simple API.

import create from 'zustand';

const useStore = create((set) => ({
  bears: 0,
  increasePopulation: () => 
    set((state) => ({ bears: state.bears + 1 })),
  removeAllBears: () => 
    set({ bears: 0 })
}));

function BearCounter() {
  const bears = useStore((state) => state.bears);
  const increase = useStore((state) => state.increasePopulation);

  return (
    <div>
      <h1>{bears} bears</h1>
      <button onClick={increase}>Add bear</button>
    </div>
  );
}

3. React Hook Form 📝

Efficient form handling with minimal re-renders.

import { useForm } from 'react-hook-form';

function SignupForm() {
  const {
    register,
    handleSubmit,
    formState: { errors }
  } = useForm();

  const onSubmit = (data) => console.log(data);

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input
        {...register('email', {
          required: 'Email is required',
          pattern: {
            value: /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i,
            message: 'Invalid email address'
          }
        })}
      />
      {errors.email && <span>{errors.email.message}</span>}

      <button type="submit">Submit</button>
    </form>
  );
}

4. Framer Motion 🎨

Beautiful animations made easy.

import { motion } from 'framer-motion';

function AnimatedCard() {
  return (
    <motion.div
      initial={{ opacity: 0, y: 20 }}
      animate={{ opacity: 1, y: 0 }}
      exit={{ opacity: 0, y: -20 }}
      whileHover={{ scale: 1.05 }}
      whileTap={{ scale: 0.95 }}
      transition={{ duration: 0.2 }}
    >
      <h2>Animated Content</h2>
      <p>This card animates on mount, hover, and exit!</p>
    </motion.div>
  );
}

5. TanStack Table 📊

Powerful tables with sorting, filtering, and pagination.

import {
  useReactTable,
  getCoreRowModel,
  getSortedRowModel,
  flexRender
} from '@tanstack/react-table';

function DataTable({ data }) {
  const columns = [
    {
      header: 'Name',
      accessorKey: 'name'
    },
    {
      header: 'Age',
      accessorKey: 'age'
    }
  ];

  const table = useReactTable({
    data,
    columns,
    getCoreRowModel: getCoreRowModel(),
    getSortedRowModel: getSortedRowModel()
  });

  return (
    <table>
      <thead>
        {table.getHeaderGroups().map(headerGroup => (
          <tr key={headerGroup.id}>
            {headerGroup.headers.map(header => (
              <th key={header.id} onClick={header.column.getToggleSortingHandler()}>
                {flexRender(
                  header.column.columnDef.header,
                  header.getContext()
                )}
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {table.getRowModel().rows.map(row => (
          <tr key={row.id}>
            {row.getVisibleCells().map(cell => (
              <td key={cell.id}>
                {flexRender(
                  cell.column.columnDef.cell,
                  cell.getContext()
                )}
              </td>
            ))}
          </tr>
        ))}
      </tbody>
    </table>
  );
}

6. React Testing Library 🧪

Write maintainable tests that simulate user behavior.

import { render, screen, fireEvent } from '@testing-library/react';
import Counter from './Counter';

test('counter increments when clicked', () => {
  render(<Counter />);

  const button = screen.getByRole('button', { name: /increment/i });
  const count = screen.getByText(/count:/i);

  expect(count).toHaveTextContent('Count: 0');

  fireEvent.click(button);

  expect(count).toHaveTextContent('Count: 1');
});

7. SWR 🔄

Simple data fetching and caching.

import useSWR from 'swr';

function Profile() {
  const { data, error, isLoading } = useSWR(
    '/api/user',
    fetcher,
    {
      revalidateOnFocus: true,
      refreshInterval: 3000
    }
  );

  if (error) return 'Error loading profile';
  if (isLoading) return 'Loading...';

  return (
    <div>
      <h1>{data.name}</h1>
      <p>{data.bio}</p>
    </div>
  );
}

8. React Spring 🌸

Physics-based animations.

import { useSpring, animated } from '@react-spring/web';

function AnimatedButton() {
  const [springs, api] = useSpring(() => ({
    from: { scale: 1 },
    config: {
      mass: 1,
      tension: 170,
      friction: 26
    }
  }));

  return (
    <animated.button
      style={springs}
      onMouseEnter={() => api.start({ scale: 1.1 })}
      onMouseLeave={() => api.start({ scale: 1 })}
    >
      Hover me!
    </animated.button>
  );
}

9. React Error Boundary 🚨

Elegant error handling.

import { ErrorBoundary } from 'react-error-boundary';

function ErrorFallback({ error, resetErrorBoundary }) {
  return (
    <div role="alert">
      <p>Something went wrong:</p>
      <pre>{error.message}</pre>
      <button onClick={resetErrorBoundary}>Try again</button>
    </div>
  );
}

function App() {
  return (
    <ErrorBoundary
      FallbackComponent={ErrorFallback}
      onReset={() => {
        // Reset app state
      }}
    >
      <ComponentThatMightError />
    </ErrorBoundary>
  );
}

10. React Virtual 📜

Efficient rendering of large lists.

import { useVirtual } from '@tanstack/react-virtual';

function VirtualList({ items }) {
  const parentRef = useRef();

  const rowVirtualizer = useVirtual({
    size: items.length,
    parentRef,
    estimateSize: useCallback(() => 35, []),
    overscan: 5
  });

  return (
    <div
      ref={parentRef}
      style={{ height: '400px', overflow: 'auto' }}
    >
      <div
        style={{
          height: `${rowVirtualizer.totalSize}px`,
          width: '100%',
          position: 'relative'
        }}
      >
        {rowVirtualizer.virtualItems.map(virtualRow => (
          <div
            key={virtualRow.index}
            style={{
              position: 'absolute',
              top: 0,
              left: 0,
              width: '100%',
              height: `${virtualRow.size}px`,
              transform: `translateY(${virtualRow.start}px)`
            }}
          >
            {items[virtualRow.index]}
          </div>
        ))}
      </div>
    </div>
  );
}
