Output

Generate fake data with @faker-js/faker. Supports vi/en/id locales (Vietnamese, Indonesian, US names…). Great for testing APIs, seeding DBs, mocking UIs.

When you need mock data

API testing: generate 1000 fake users to stress-test POST /users.
Seed databases: dev environment needs data — generate SQL INSERT scripts to run once.
UI mockups: backend not ready — fake data lets you demo to stakeholders.
Frontend demos: Storybook components need realistic data to show edge cases (long names, unusual emails).
Privacy compliance: replace real data with fakes to share datasets with contractors or open-source.

Vietnamese (vi): real Vietnamese surnames (Nguyễn, Trần, Lê), Hanoi/HCMC addresses.
