# Migration Guide — Adopting `@bytelyst/*` Packages
Step-by-step guide for integrating `@bytelyst/*` shared packages into a new product or dashboard.
---
## Prerequisites
1. Clone both repos side-by-side:
```
code/
├── learning_ai_common_plat/ # shared packages + services
└── your-product/ # your product repo
```
2. Build all packages:
```bash
cd learning_ai_common_plat
pnpm install
pnpm build
```
---
## Step 1: Add Package Dependencies
In your product's `package.json`, add `file:` references to the packages you need:
```json
{
"dependencies": {
"@bytelyst/errors": "file:../learning_ai_common_plat/packages/errors",
"@bytelyst/cosmos": "file:../learning_ai_common_plat/packages/cosmos",
"@bytelyst/config": "file:../learning_ai_common_plat/packages/config",
"@bytelyst/auth": "file:../learning_ai_common_plat/packages/auth",
"@bytelyst/api-client": "file:../learning_ai_common_plat/packages/api-client",
"@bytelyst/logger": "file:../learning_ai_common_plat/packages/logger"
}
}
```
Adjust the `../` path depth based on your directory structure. Then run `npm install`.
> **Important:** Run `pnpm build` in `learning_ai_common_plat` before `npm install` in your product. The `file:` refs need compiled `dist/` directories.
---
## Step 2: Wire Up Cosmos DB
Create `src/lib/cosmos.ts`:
```typescript
import {
getCosmosClient,
getDatabase,
registerContainers,
getRegisteredContainer,
} from '@bytelyst/cosmos';
// Define your containers
const CONTAINERS = [
'users',
'settings',
'audit_log',
// ... your containers
];
let initialized = false;
export async function initializeAllContainers() {
if (initialized) return;
await registerContainers(CONTAINERS);
initialized = true;
}
export function getContainer(name: string) {
return getRegisteredContainer(name);
}
export { getCosmosClient, getDatabase, initializeAllContainers };
```
Required env vars: `COSMOS_ENDPOINT`, `COSMOS_KEY`, `COSMOS_DATABASE`
---
## Step 3: Wire Up Auth (Server-Side)
Create `src/lib/auth-server.ts`:
```typescript
import { createJwtUtils, hashPassword, verifyPassword } from '@bytelyst/auth';
const jwt = createJwtUtils({
issuer: 'your-product-name',
accessTokenExpiry: '1h',
refreshTokenExpiry: '30d',
});
export { jwt, hashPassword, verifyPassword };
```
Required env var: `JWT_SECRET` (min 32 chars)
---
## Step 4: Wire Up Product Identity
Create `src/lib/product-config.ts`:
```typescript
import { loadProductIdentity } from '@bytelyst/config';
const identity = loadProductIdentity();
export const PRODUCT_ID = identity.productId;
export const PRODUCT_NAME = identity.productName;
```
Required env vars: `DEFAULT_PRODUCT_ID` (or set in `shared/product.json`)
> **Rule:** Every Cosmos document MUST include a `productId` field using this value.
---
## Step 5: Wire Up Service Clients (If Using Microservices)
Create `src/lib/billing-client.ts` (example):
```typescript
import { createApiClient } from '@bytelyst/api-client';
const billingApi = createApiClient({
baseUrl: process.env.BILLING_SERVICE_URL || 'http://localhost:4002',
getToken: () => {
// Return the current user's JWT token
return localStorage.getItem('access_token');
},
});
export async function getSubscription(userId: string) {
return billingApi.fetch(`/api/subscriptions/${userId}`);
}
```
---
## Step 6: Wire Up Error Handling
Import typed errors for consistent HTTP error responses:
```typescript
import {
BadRequestError,
UnauthorizedError,
ForbiddenError,
NotFoundError,
ConflictError,
} from '@bytelyst/errors';
// In your API routes:
if (!user) throw new NotFoundError('User not found');
if (!isAdmin) throw new ForbiddenError('Admin access required');
```
---
## Step 7: Wire Up Auth Context (React Dashboards)
For admin-style dashboards, use the factory:
```typescript
import { createAuthProvider } from '@bytelyst/react-auth';
interface MyUser {
id: string;
email: string;
role: string;
}
const { AuthProvider, useAuth } = createAuthProvider<MyUser>({
storagePrefix: 'myapp',
onLoginFallback: async (email, password) => {
const res = await fetch('/api/auth/login', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ email, password }),
});
if (!res.ok) return null;
const data = await res.json();
return { user: data.user, token: data.accessToken };
},
});
export { AuthProvider, useAuth };
```
> **Note:** If your auth flow needs SSO cookies, registration, or session restore via API calls, keep a custom auth context instead.
---
## Docker Builds
### Fastify Services (in `learning_ai_common_plat`)
Services use pnpm monorepo builds with repo root as context. See any service's `Dockerfile` for the pattern:
- Multi-stage: `pnpm install` → build packages + service → `pnpm deploy`
- `docker-compose.yml` sets `context: .` with `dockerfile: services/<name>/Dockerfile`
### Next.js Dashboards (in your product repo)
Dashboards need pre-built packages copied into the build context:
1. Run `./scripts/docker-prep-dashboards.sh` to copy `@bytelyst/*` into `.docker-deps/`
2. Dockerfile copies `.docker-deps/@bytelyst/` to `/learning_ai_common_plat/packages/` so `file:` refs resolve
