Parameterized Server Actions

Create a Next.js 14 server action that accepts URL parameters to fetch and return specific resources from a database.
import { NextRequest, NextResponse } from 'next/server';

// This function represents the Server Action
export async function action(req) {
    // Extracting the URL parameter 'resourceId'
    const { resourceId } = req.nextUrl.query;

    // Fetch the specific resource from the database
    // You should replace 'databaseApiCall' with your actual database fetch function
    const resource = await databaseApiCall(resourceId);

    // Return the resource in the response
    return new NextResponse(JSON.stringify(resource), {
        status: 200,
        headers: {
            'Content-Type': 'application/json'

// Example database fetch function (should be replaced with your database logic)
async function databaseApiCall(id) {
    // Replace with actual database fetching logic
    // Here we simulate fetching the resource by returning an object
    return { id, name: 'Resource Name', description: 'Resource Description' };
This piece of code defines a Next.js Server Action that fetches a resource from a database using a URL parameter. It uses a mock 'databaseApiCall' function to simulate fetching data which should be replaced with actual database interaction logic.
