Mock Data

Produces believable, deterministic sample data for demos, seeds, and UI states.

Principles

• Deterministic by default: use a seeded PRNG (e.g. seedrandom, or a fixed seed with faker/@faker-js/faker's faker.seed(n)) so the same data regenerates every run — reproducible demos.
• Realistic, not random garbage: names, emails, and text should look human (faker does this well). Avoid lorem-ipsum for UI demos when domain text is better.
• Consistent referential integrity: if you fake users, also fake their posts/orders/comments referencing those same IDs.
• Boundaries included: include edge cases deliberately — empty lists, one item, max-length strings, a null/undefined field — so the UI is tested against real states.
