4. JavaScript — Populate a Table

fetch('https://softwium.com/fake-api/users')
  .then(r => r.json())
  .then(users => {
    const table = document.getElementById('user-table');
    users.forEach(u => {
      const row = table.insertRow();
      row.innerHTML = `
        ${u.name}
        ${u.email}
        ${u.phone}
        ${u.city}
      `;
    });
  });

5. Python — Generate Test Data

import requests, json

# Get fake products for testing
products = requests.get(
    'https://softwium.com/fake-api/products'
).json()

for p in products[:5]:
    print(f"{p['name']} — ${p['price']}")
    print(f"  Category: {p['category']}")
    print(f"  In stock: {p['stock']}")

# Save as test fixture
with open('test_products.json', 'w') as f:
    json.dump(products, f, indent=2)

Frequently Asked Questions

What data types are available?: Softwium provides fake data for users, products, posts, comments, todos, and more. Each endpoint returns structured JSON with realistic field values appropriate for the data type.
Are the consistent across requests?: Data is randomly generated on each request. For deterministic test data, you may need to cache responses client-side or use a mocking library.
Can I specify the number of results?: Most endpoints support a ?limit parameter to control the number of items returned. Default is typically 10 items per request.
Is the data realistic for production testing?: Yes — names, emails, product descriptions, and prices are generated to look realistic. However, all data is fictional; no real users, products, or companies are represented.
Are there any rate limits?: Softwium is free for reasonable development and testing use. If you need high-volume data generation, consider client-side libraries like Faker.js.
Does it support filtering or search?: The basic Fake API returns random data. For filtered, searchable, or paginated data, consider more comprehensive mocking solutions like JSON Server or Mirage JS.
