FakeData

FakeData is a lightweight command-line tool and JavaScript library built to generate mock data structures quickly. Supporting custom layouts, locale-specific variations, and random seed generation, it helps developers mock APIs and seed databases.

Key Features of FakeData

• Multi-Locale Generation: Produces realistic name, address, and phone inputs localized for over 40 countries.
• Seedable Randomness: Ensures random data generation runs remain reproducible by locking seed numbers.
• Custom Schema Maps: Define unique structures (e.g. users, products) using declarative schema maps.
• Zero External Dependencies: Very small package size, making it quick and easy to install in environments.

Benefits of Using FakeData

• Fast API Mocking: Set up mock endpoints that deliver realistic JSON structures in seconds.
• Deterministic Testing: Seeded data ensures integration tests remain consistent and reproducible across runs.
• Protect User Data: Skip copying production databases; seed development databases with clean mock structures.

To speed up manual form completion, FakeData allows testers to generate mock addresses, JSON files, and contact details with a single click.
