Why LoreData

• Generic demo users like John Doe, Jane Smith, and [email protected] work for smoke tests but feel flat in real product demos
• LoreData generates recognizable personas from a single fictional universe, so fields stay coherent by design
• Deterministic output via seed keeps fixtures stable across runs
• Works in Node.js, browser, and as a CLI tool with no network requests

Who this is for

• developers filling a local database or Storybook stories with recognizable personas
• designers building mockups who do not want to use John Doe again
• QA engineers creating more expressive test accounts with different profiles
• tutorial and conference talk authors who want screenshots that feel less generic

Features

• [x] 29 universes
• [x] Single persona and group generation
• [x] Filter characters by interest, name, universe
• [x] Deterministic output via seed
• [x] Browser-safe entry point
• [x] CLI tool
• [x] Character symbol and color fields

Install

# library
npm install loredata

# CLI
npm install -g loredata

Usage example

import { person, group } from 'loredata';

const p = person({ universe: 'breaking-bad' });
// {
//   firstName: 'Walter',
//   lastName: 'White',
//   username: 'heisenberg',
//   email: '[email protected]',
//   quote: "I am the one who knocks.",
//   profession: 'Chemistry teacher',
//   interests: ['chemistry', 'cooking', 'family'],
//   address: { street: '308 Negra Arroyo Lane', city: 'Albuquerque', state: 'NM' },
//   symbol: '☢️',
//   color: '#4c1d95',
//   universe: 'breaking-bad',
//   universeName: 'Breaking Bad'
// }

const team = group({ universe: 'game-of-thrones', size: 3 });
// [
//   { firstName: 'Jon', lastName: 'Snow', username: 'lord_commander', ... },
//   { firstName: 'Daenerys', lastName: 'Targaryen', username: 'mother_of_dragons', ... },
//   { firstName: 'Tyrion', lastName: 'Lannister', username: 'halfman', ... },
// ]

Persona fields

Each Person includes:

• firstName, lastName
• username, email
• address, profession, interests
• quote, symbol, color
• universe, universeName

Deterministic output

If you need reproducible results, for example for test fixtures, just pass a seed:

const p = person({ universe: 'matrix', seed: 42 });
const team = group({ universe: 'matrix', size: 3, seed: 42 });

Given the same seed, you always get the same persona or the same group.

Browser

The library also supports browser environments through a separate entry point with no dependency on fs or path:

import { loadUniverse, personFromData } from 'loredata/browser';

const universe = await loadUniverse('breaking-bad');
const p = personFromData(universe);

It works with Vite, webpack, and any browser bundler.

CLI

loredata person --universe breaking-bad
loredata person --universe breaking-bad --format json
loredata person --interests chemistry,cooking
loredata person --interests chemistry,cooking --interests-mode and
loredata person --name walter
loredata group --universe friends --size 5
loredata universes

Universes

import { universes } from 'loredata';

universes();
// [
//   { id: 'sherlock', name: 'Sherlock', genre: ['crime', 'drama', 'mystery'], description: '...' },
//   { id: 'game-of-thrones', name: 'Game of Thrones', genre: ['fantasy', 'drama', 'action'], description: '...' },
//   ...
// ]

For API/CLI usage, use universe IDs such as the-office and game-of-thrones.
