Implement React Server Components in Next.js
React Server Components (RSC) allow components to render on the server, reducing the amount of JavaScript sent to the client and improving initial load times. They are particularly useful for simplifying data fetching, as data can be retrieved on the server and passed directly to the component without needing a separate client-side API call.
```
import { getUserData } from "../lib/api";

export default async function UserProfile() {
  // Data is fetched directly on the server
  const user = await getUserData();

  return (
    <div>
      <h1>{user.name}</h1>
      <p>{user.email}</p>
    </div>
  );
}
```

Implement a recursive File Explorer component hierarchy in React

Build a file system by creating a set of mutually recursive components. The FileExplorer component iterates through the data; if it encounters a folder, it renders a Folder component. The Folder component, in turn, renders another FileExplorer instance to display its nested children, creating the recursive UI loop.

// FileExplorer.jsx
import React, { useState } from "react";
import Folder from "./Folder";
import File from "./File";

const FileExplorer = ({ files }) => {
  return (
    <div>
      {files.map((file) =>
        file.type === "folder" ? (
          <Folder
            key={file.id}
            folder={file}
            onAdd={addItem}
            onRename={renameItem}
            onDelete={deleteItem}
          />
        ) : (
          <File
            key={file.id}
            file={file}
            onRename={renameItem}
            onDelete={deleteItem}
          />
        )
      )}
    </div>
  );
};

// Folder.jsx
import React from "react";
import FileExplorer from "./FileExplorer";

const Folder = ({ folder, onAdd, onRename, onDelete }) => {
  return (
    <div>
      <h3>{folder.name}</h3>
      <button onClick={() => onAdd(folder.id, "folder")}>Add Folder</button>
      <button onClick={() => onAdd(folder.id, "file")}>Add File</button>
      <button onClick={() => onRename(folder.id, "New Name")}>Rename</button>
      <button onClick={() => onDelete(folder.id)}>Delete</button>
      {/* Recursive call to render nested children */}
      {folder.children && <FileExplorer files={folder.children} />}
    </div>
  );
};

// File.jsx
import React from "react";

const File = ({ file, onRename, onDelete }) => {
  return (
    <div>
      <p>{file.name}</p>
      <button onClick={() => onRename(file.id, "New Name")}>Rename</button>
      <button onClick={() => onDelete(file.id)}>Delete</button>
    </div>
  );
};

Use Server Actions for server-side logic in Next.js

Server Actions are asynchronous functions that execute on the server in response to client-side events (like form submissions). They allow developers to handle sensitive operations and server-side logic directly from React components, reducing the need for manual API route creation and minimizing client-side JavaScript.

// app/actions/submit.js
import { saveFormData } from "../lib/api";

export async function submitForm(data) {
  await saveFormData(data);
  return { success: true };
}

// contactForm.js
"use client";

import { submitForm } from "../actions/submitForm";

export default function ContactForm() {
  const handleSubmit = async (event) => {
    event.preventDefault();
    const formData = new FormData(event.target);
    // Call the server action directly
    const result = await submitForm(Object.fromEntries(formData));
    if (result.success) {
      alert("Form submitted successfully!");
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <label>
        Name:
        <input type="text" name="name" required />
      </label>
      <label>
        Email:
        <input type="email" name="email" required />
      </label>
      <button type="submit">Submit</button>
    </form>
  );
}

Design a recursive data structure for a React file system
To represent a hierarchical file system, use a recursive data structure where each object represents either a file or a folder. Folders must include a children array containing further file or folder objects, allowing for infinite nesting.
```
const folder = {
  id: "1",
  name: "Documents",
  type: "folder",
  children: [
    { id: "2", name: "Resume.pdf", type: "file" },
    { id: "3", name: "CoverLetter.docx", type: "file" },
  ],
};
```

Manage state for recursive file system actions

Use React's useState hook to maintain the file system tree. Implement handler functions for adding, renaming, and deleting items. These functions should traverse the recursive data structure to find the target item by its id and update the state immutably.

const [files, setFiles] = useState(initialData);

const addItem = (parentId, type) => {
  // Logic to find parentId in the tree and push a new object to its children array
};

const renameItem = (id, newName) => {
  // Logic to find the item by id and update its name property
};

const deleteItem = (id) => {
  // Logic to filter out the item with the matching id from the children array
};
