# Miro SDK Patterns

## Overview

Production-ready patterns for the `@mirohq/miro-api` Node.js client and direct REST API v2 usage. Covers the high-level `Miro` client (stateful, OAuth-aware) and the low-level `MiroApi` client (stateless, token-based).

## Prerequisites

- `@mirohq/miro-api` installed
- TypeScript 5+ project
- Understanding of Miro REST API v2 item model

## Two Client Modes

```typescript
import { Miro, MiroApi } from '@mirohq/miro-api';

// HIGH-LEVEL: Stateful, manages OAuth tokens per user
// Use for multi-user apps (SaaS, web apps with OAuth)
const miro = new Miro({
  clientId: process.env.MIRO_CLIENT_ID!,
  clientSecret: process.env.MIRO_CLIENT_SECRET!,
  redirectUrl: process.env.MIRO_REDIRECT_URI!,
});
const userApi = await miro.as('user-id');  // Returns MiroApi scoped to user

// LOW-LEVEL: Stateless, pass token directly
// Use for scripts, automation, single-user integrations
const api = new MiroApi(process.env.MIRO_ACCESS_TOKEN!);
```

## Pattern 1: Type-Safe Board Service

```typescript
// src/miro/board-service.ts
import { MiroApi } from '@mirohq/miro-api';

// Response types matching Miro REST API v2
interface MiroBoard {
  id: string;
  type: 'board';
  name: string;
  description: string;
  createdAt: string;
  modifiedAt: string;
}

interface MiroBoardItem {
  id: string;
  type: 'sticky_note' | 'shape' | 'card' | 'text' | 'frame' | 'image' | 'document' | 'embed' | 'app_card';
  data: Record<string, unknown>;
  position: { x: number; y: number; origin: string };
  geometry?: { width?: number; height?: number };
  createdAt: string;
  createdBy: { id: string; type: string };
}

interface PaginatedResponse<T> {
  data: T[];
  total: number;
  size: number;
  offset: number;
  limit: number;
  cursor?: string;
}

export class BoardService {
  constructor(private api: MiroApi) {}

  async getBoard(boardId: string): Promise<MiroBoard> {
    const response = await this.api.getBoard(boardId);
    return response.body as unknown as MiroBoard;
  }

  async listItems(
    boardId: string,
    options: { type?: string; limit?: number; cursor?: string } = {}
  ): Promise<PaginatedResponse<MiroBoardItem>> {
    const params = new URLSearchParams();
    if (options.type) params.set('type', options.type);
    if (options.limit) params.set('limit', String(options.limit));
    if (options.cursor) params.set('cursor', options.cursor);

    const response = await fetch(
      `https://api.miro.com/v2/boards/${boardId}/items?${params}`,
      { headers: this.authHeaders() }
    );
    return response.json();
  }

  async getAllItems(boardId: string): Promise<MiroBoardItem[]> {
    const items: MiroBoardItem[] = [];
    let cursor: string | undefined;

    do {
      const page = await this.listItems(boardId, { limit: 50, cursor });
      items.push(...page.data);
      cursor = page.cursor;
    } while (cursor);

    return items;
  }

  private authHeaders() {
    return {
      'Authorization': `Bearer ${process.env.MIRO_ACCESS_TOKEN}`,
      'Content-Type': 'application/json',
    };
  }
}
```

## Pattern 2: Item Factory

```typescript
// src/miro/item-factory.ts
type StickyNoteColor = 'light_yellow' | 'light_green' | 'light_blue'
  | 'light_pink' | 'gray' | 'light_cyan' | 'light_orange';

interface CreateStickyNoteParams {
  boardId: string;
  content: string;
  color?: StickyNoteColor;
  x?: number;
  y?: number;
  width?: number;
}

interface CreateShapeParams {
  boardId: string;
  content: string;
  shape?: 'rectangle' | 'circle' | 'triangle' | 'rhombus'
    | 'round_rectangle' | 'parallelogram' | 'star'
    | 'right_arrow' | 'left_arrow' | 'pentagon' | 'hexagon'
    | 'octagon' | 'trapezoid' | 'flow_chart_predefined_process'
    | 'can' | 'cross' | 'cloud';
  fillColor?: string;
  x?: number;
  y?: number;
  width?: number;
  height?: number;
}

interface CreateCardParams {
  boardId: string;
  title: string;
  description?: string;
  dueDate?: string;       // ISO 8601 date
  assigneeId?: string;
  x?: number;
  y?: number;
}

export class ItemFactory {
  constructor(private token: string) {}

  async createStickyNote(params: CreateStickyNoteParams): Promise<MiroBoardItem> {
    return this.post(`/v2/boards/${params.boardId}/sticky_notes`, {
      data: { content: params.content, shape: 'square' },
      style: { fillColor: params.color ?? 'light_yellow', textAlign: 'center' },
      position: { x: params.x ?? 0, y: params.y ?? 0 },
      geometry: { width: params.width ?? 199 },
    });
  }

  async createShape(params: CreateShapeParams): Promise<MiroBoardItem> {
    return this.post(`/v2/boards/${params.boardId}/shapes`, {
      data: { content: params.content, shape: params.shape ?? 'round_rectangle' },
      style: { fillColor: params.fillColor ?? '#4262ff', textAlign: 'center' },
      position: { x: params.x ?? 0, y: params.y ?? 0 },
      geometry: { width: params.width ?? 200, height: params.height ?? 100 },
    });
  }

  async createCard(params: CreateCardParams): Promise<MiroBoardItem> {
    return this.post(`/v2/boards/${params.boardId}/cards`, {
      data: {
        title: params.title,
        description: params.description,
        dueDate: params.dueDate,
        assigneeId: params.assigneeId,
      },
      position: { x: params.x ?? 0, y: params.y ?? 0 },
    });
  }

  private async post(path: string, body: unknown): Promise<MiroBoardItem> {
    const res = await fetch(`https://api.miro.com${path}`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${this.token}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(body),
    });

    if (!res.ok) {
      const err = await res.json();
      throw new MiroApiError(res.status, err.message ?? 'API request failed', err.code);
    }
    return res.json();
  }
}
```

## Pattern 3: Error Handling Wrapper

```typescript
// src/miro/errors.ts
export class MiroApiError extends Error {
  constructor(
    public readonly status: number,
    message: string,
    public readonly code?: string,
  ) {
    super(message);
    this.name = 'MiroApiError';
  }

  get isRetryable(): boolean {
    return this.status === 429 || (this.status >= 500 && this.status < 600);
  }

  get isAuthError(): boolean {
    return this.status === 401 || this.status === 403;
  }
}

async function safeMiroCall<T>(
  operation: () => Promise<T>,
  context: string
): Promise<{ data: T | null; error: MiroApiError | null }> {
  try {
    const data = await operation();
    return { data, error: null };
  } catch (err) {
    if (err instanceof MiroApiError) {
      console.error(`[Miro:${context}] ${err.status}: ${err.message}`);
      return { data: null, error: err };
    }
    throw err;  // Re-throw unexpected errors
  }
}
```

## Pattern 4: Multi-Tenant Client Factory

```typescript
// src/miro/multi-tenant.ts
import { Miro, MiroApi } from '@mirohq/miro-api';

// For SaaS apps serving multiple Miro users
const clients = new Map<string, MiroApi>();

export async function getClientForUser(userId: string): Promise<MiroApi> {
  if (!clients.has(userId)) {
    const miro = new Miro({
      clientId: process.env.MIRO_CLIENT_ID!,
      clientSecret: process.env.MIRO_CLIENT_SECRET!,
      redirectUrl: process.env.MIRO_REDIRECT_URI!,
    });

    if (!await miro.isAuthorized(userId)) {
      throw new Error(`User ${userId} has not authorized Miro`);
    }

    const api = await miro.as(userId);
    clients.set(userId, api);
  }

  return clients.get(userId)!;
}
```

## Pattern 5: Response Validation with Zod

```typescript
import { z } from 'zod';

const MiroBoardSchema = z.object({
  id: z.string(),
  type: z.literal('board'),
  name: z.string(),
  description: z.string().optional(),
  createdAt: z.string().datetime(),
  modifiedAt: z.string().datetime(),
});

const MiroItemSchema = z.object({
  id: z.string(),
  type: z.enum(['sticky_note', 'shape', 'card', 'text', 'frame', 'image', 'document', 'embed', 'app_card']),
  data: z.record(z.unknown()),
  position: z.object({ x: z.number(), y: z.number() }),
});

function validateBoardResponse(data: unknown) {
  return MiroBoardSchema.parse(data);
}
```

## Error Handling

| Pattern | Use Case | Benefit |
|---------|----------|---------|
| Type-safe service | Board/item CRUD | Catches shape mismatches at compile time |
| Item factory | Bulk item creation | Consistent defaults, validated params |
| Error wrapper | All API calls | Classifies errors as retryable vs auth vs input |
| Multi-tenant | SaaS applications | Isolates users, manages token lifecycle |
| Zod validation | Response parsing | Runtime safety against API changes |
