# @bytelyst/common-platform

Shared packages for the ByteLyst ecosystem — used by [LysnrAI](https://github.com/saravanakumardb1/learning_voice_ai_agent) and [MindLyst](https://github.com/saravanakumardb1/learning_multimodal_memory_agents).

## Packages

| 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) | — |

## Quick Start

```bash
# Install dependencies
pnpm install

# Build all packages
pnpm build

# Run all tests
pnpm test

# Type-check all packages
pnpm typecheck
```

## Consuming from LysnrAI / MindLyst

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

```jsonc
// From Fastify services (3 levels up):
"@bytelyst/errors": "file:../../../learning_ai_common_plat/packages/errors"

// From Next.js dashboards 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:

```bash
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
