@deina-labs/deina-core

Shared dating archetype logic, quiz data, onboarding content, and coaching characters for the Deina ecosystem. Used by the mobile app (React Native/Expo), web app, and Supabase edge functions.

Zero runtime dependencies. Pure TypeScript data + logic.

Installation

Option 1: npm (recommended)

yarn add @deina-labs/deina-core

Option 2: GitHub dependency

In your consuming project's package.json:

{
  "dependencies": {
    "@deina-labs/deina-core": "github:joynOS/deina-core"
  }
}

Then run:

yarn install

Option 3: Local development (linking)

If you're working on deina-core alongside another project locally:

# In deina-core/
yarn install
yarn build

# In your consuming project/
yarn add link:../deina-core

Option 4: Supabase Edge Functions (Deno)

import { classifyArchetype, DATING_ARCHETYPES } from 'npm:@deina-labs/deina-core';

For the npm: specifier to work, the package must be published to npm or use an import map pointing to the GitHub dependency.

Build

yarn install
yarn build

This compiles src/ to dist/ with type declarations.

Usage

Importing in React Native / Expo

import {
  DATING_ARCHETYPES,
  classifyArchetype,
  STANDARDS_QUALITIES,
  TIMELINE_QUESTIONS,
  MINDSET_QUESTIONS,
  ENFORCEMENT_QUESTIONS,
  TRADEOFF_QUESTIONS,
} from '@deina-labs/deina-core';

// Classify a user's archetype from their quiz answers
const archetype = classifyArchetype({
  standards: { physicalAttraction: 4, emotionalStability: 5, ... },
  timelineAnswers: { progressionPace: 'Structured and steady', ... },
  mindsetAnswers: { standardsConfidence: '4', ... },
  enforcementAnswers: { cancelDowngrade: '1 time', ... },
  tradeOffAnswers: { consistencyVsChemistry: 'Consistent effort even if chemistry builds slowly', ... },
});

console.log(archetype.name); // "The Strategic Dater"
console.log(archetype.signatureLine); // "You trust patterns more than promises."

Using onboarding content

import {
  DISCLAIMER_CONTENT,
  SECTION_INTROS,
  ABOUT_YOU_CONTENT,
} from '@deina-labs/deina-core';

// All screen copy is centralized — no hardcoded strings in your UI
<Text>{DISCLAIMER_CONTENT.heading}</Text>
<Text>{SECTION_INTROS.standards.body}</Text>

Coaching context for AI prompts

import { buildArchetypeContext } from '@deina-labs/deina-core';

const context = buildArchetypeContext('the-strategic-dater');
// Returns a formatted string with traits, pitfalls, and coaching directive
// ready to inject into a system prompt

Deina characters

import { DEINA_CHARACTERS, getDeinaById } from '@deina-labs/deina-core';

const deina = getDeinaById('blonde');
console.log(deina.name); // "Chloe"
console.log(deina.tone); // "The Optimistic Strategist"
console.log(deina.systemPromptModifier); // system prompt personality modifier

Share card HTML (edge functions)

import { renderArchetypePage, renderNotFoundPage } from '@deina-labs/deina-core';

// Returns a full HTML page string
const html = renderArchetypePage(archetype, 'Josephine');
const notFound = renderNotFoundPage();
