Real-World Applications & Architecture

Built with Playground API

See how developers use Playground API to build full-stack frontends, stateful mock stores, and automated test suites with zero backend infrastructure.

Official Featured App

Playground React E-Commerce Store & Studio

A production-ready React 18 e-commerce application featuring product catalog management, interactive cart drawer, JWT authentication, and isolated session sandbox mutations.

Try in API Studio View Source Code

Dynamic Products

Uses /custom/products to allow users to add, edit, and delete products that persist on page reload.

Cart & Checkout

Real-time cart drawer with automatic total calculation and mock order submission.

JWT Auth Flow

Loading Skeletons

Tests skeleton loaders seamlessly with ?_delay=1500.

How the React Demo Integrates with Playground API:

playground_api_react_demo/src/hooks/useProducts.js

// Example from playground_api_react_demo

import { useState, useEffect } from 'react';

export function useProductCatalog() {

const [products, setProducts] = useState([]);

const [loading, setLoading] = useState(true);

// 1. Fetch dynamic products with persistent sandbox overlay

const fetchProducts = async () => {

setLoading(true);

try {

const res = await fetch('https://playground.nileslabs.com/api/v1/custom/products?_sort=createdAt&_order=desc', {

credentials: 'include',

});

const data = await res.json();

setProducts(data.data || []);

} finally {

setLoading(false);

}

};

// 2. Create a new custom product (Persists in user session!)

const addProduct = async (productData) => {

const res = await fetch('https://playground.nileslabs.com/api/v1/custom/products', {

method: 'POST',

headers: { 'Content-Type': 'application/json' },

credentials: 'include',

body: JSON.stringify(productData),

});

if (res.ok) {

await fetchProducts(); // Refresh list to see the newly created item

}

};

useEffect(() => {

fetchProducts();

}, []);

return { products, loading, addProduct };

}
