Shared Libraries

Package	Description	Peer Dependencies
@bytelyst/errors	Typed HTTP service errors (400–429)	—
@bytelyst/cosmos	Azure Cosmos DB client singleton + container registry	@azure/cosmos
@bytelyst/config	Zod-based env config loader + product identity	zod
@bytelyst/auth	JWT utilities, auth middleware, password hashing	jose, bcryptjs
@bytelyst/api-client	Configurable fetch wrapper with auth token injection	—
@bytelyst/react-auth	React auth context factory (typed provider + hook)	react
@bytelyst/design-tokens	Cross-platform design tokens (JSON → CSS/TS/Kotlin/Swift)	—

Shared Services

Service	Port	Description	Tests
platform-service	4003	Auth, audit, feature flags, notifications, blob storage	55
billing-service	4002	Subscriptions, Stripe webhooks, usage tracking, licenses, plans	32
growth-service	4001	Invitations, referrals, promo codes	33
tracker-service	4004	Feature requests, bugs, tasks, public roadmap	45
monitoring	—	Loki + Grafana dashboards, health-check script	—

All services are product-agnostic — every Cosmos document includes a productId field, so a single deployment serves LysnrAI, MindLyst, or any future product.

Quick Start

# Install dependencies
pnpm install

# Build all packages + services
pnpm build

# Run all tests (165 total across packages + services)
pnpm test

# Type-check all packages
pnpm typecheck

# Run a specific service in dev mode
pnpm --filter @lysnrai/platform-service dev

Consuming Libraries from Product Repos

During development, use file: references in consumer package.json:

// From a Next.js dashboard at repo root (2 levels up):
"@bytelyst/errors": "file:../../learning_ai_common_plat/packages/errors"

// From MindLyst web (3 levels up — inside mindlyst-native/web/):
"@bytelyst/design-tokens": "file:../../../learning_ai_common_plat/packages/design-tokens"

All repos must be cloned side-by-side under the same parent directory.

Design Tokens

Generate platform-specific token files from the canonical JSON:

cd packages/design-tokens
pnpm generate

Outputs in packages/design-tokens/generated/:

• tokens.css — CSS custom properties (--ml-*)
• tokens.ts — TypeScript constants
• MindLystTokens.kt — Kotlin object for KMP
• MindLystTheme.swift — Swift structs for SwiftUI

Roadmap
