A TypeScript library for RPG stat management with D&D 5e-style mechanics, dice rolling, and stat checks.
- Flexible Dice Rolling - Full notation parser with advantage, keep/drop, exploding, and rerolls
- Stat Management - Define stats with bounds, modifiers, and automatic calculations
- D&D 5e-Style Checks - Advantage/disadvantage, custom dice, and bonuses
- Derived Stats - Auto-updating computed stats based on dependencies
- Duration System - Temporary and permanent modifiers with expiration
- Roll History - Track all rolls for audit trails
- Stat Templates - Create reusable stat block configurations
- Serialization - Save and restore complete stat block state
import { createStatBlock, roll, check } from '@motioneffector/stats'
// Create a character with stats
const hero = createStatBlock({
strength: { base: 16, min: 1, max: 20 },
dexterity: { base: 14, min: 1, max: 20 },
health: { base: 45, min: 0, max: 100 }
})
// Roll dice with full notation support
const damage = roll('2d6+3') // { total: 11, rolls: [4, 4], modifier: 3 }
// Make a strength check with D&D 5e mechanics
const result = check(hero, 'strength', { difficulty: 15 })
// { success: true, roll: 14, modifier: 3, total: 17 }- Comprehensive test suite - 367 unit tests covering core functionality
- Fuzz tested - Randomized input testing to catch edge cases
- Strict TypeScript - Full type coverage with no
anytypes - Zero dependencies - No supply chain risk
