# Miro Upgrade & Migration

## Overview

Guide for migrating from Miro REST API v1 to v2, upgrading the `@mirohq/miro-api` SDK, and handling the key breaking changes between versions.

## Key Breaking Changes: v1 to v2

### Terminology Changes

| v1 Term | v2 Term | Notes |
|---------|---------|-------|
| Widget | Item | All board elements renamed |
| Line | Connector | Lines renamed, gained captions and snapTo |
| Sticker | Sticky Note | Type value: `sticky_note` |
| Widget API (polymorphic) | Per-type endpoints | No more universal create endpoint |
| `text` property | `content` property | In data objects |
| `shapeType` | `shape` (in `data`) | Moved from style to data object |
| `startWidget` / `endWidget` | `startItem` / `endItem` | Connector endpoints |
| Board User Connection | Board Member | Sharing/permissions model |

### Endpoint Migration Map

```
# v1 (DEPRECATED)                          → v2 (CURRENT)
POST /v1/boards/{id}/widgets               → POST /v2/boards/{id}/sticky_notes
                                              POST /v2/boards/{id}/shapes
                                              POST /v2/boards/{id}/cards
                                              POST /v2/boards/{id}/texts
                                              POST /v2/boards/{id}/frames
                                              POST /v2/boards/{id}/images
                                              POST /v2/boards/{id}/documents
                                              POST /v2/boards/{id}/embeds
                                              POST /v2/boards/{id}/app_cards

GET  /v1/boards/{id}/widgets               → GET  /v2/boards/{id}/items
GET  /v1/boards/{id}/widgets/{widget_id}   → GET  /v2/boards/{id}/items/{item_id}
                                              (or type-specific: /v2/boards/{id}/sticky_notes/{item_id})

POST /v1/boards/{id}/widgets (type: line)  → POST /v2/boards/{id}/connectors
GET  /v1/boards/{id}/widgets?type=line     → GET  /v2/boards/{id}/connectors
```

### Request Body Changes

```typescript
// v1: Create a sticky note (via universal widgets endpoint)
// POST /v1/boards/{id}/widgets
{
  "type": "sticker",
  "text": "Hello World",
  "style": {
    "stickerBackgroundColor": "#FFFF00"
  },
  "x": 100,
  "y": 200,
  "width": 200
}

// v2: Create a sticky note (dedicated endpoint)
// POST /v2/boards/{id}/sticky_notes
{
  "data": {
    "content": "Hello World",      // "text" → "content"
    "shape": "square"              // Required in v2
  },
  "style": {
    "fillColor": "light_yellow"    // Named colors or hex
  },
  "position": {
    "x": 100,                      // Nested under "position"
    "y": 200
  },
  "geometry": {
    "width": 200                   // Nested under "geometry"
  }
}
```

```typescript
// v1: Connector (line)
{
  "type": "line",
  "startWidget": { "id": "123" },
  "endWidget": { "id": "456" }
}

// v2: Connector
{
  "startItem": { "id": "123", "snapTo": "right" },    // Gains snapTo/position
  "endItem": { "id": "456", "snapTo": "left" },
  "captions": [{ "content": "connects to" }],          // New: captions
  "shape": "curved",                                     // New: shape control
  "style": {
    "startStrokeCap": "none",
    "endStrokeCap": "stealth"
  }
}
```

## SDK Upgrade Steps

### Step 1: Check Current Version and Update

```bash
# Check current version
npm list @mirohq/miro-api

# View available versions
npm view @mirohq/miro-api versions --json | tail -5

# Create upgrade branch
git checkout -b upgrade/miro-api-v2

# Install latest
npm install @mirohq/miro-api@latest
```

### Step 2: Update Import Patterns

```typescript
// OLD: Some early SDK versions
import { MiroClient } from '@miro/sdk';

// CURRENT: Official @mirohq/miro-api
import { Miro, MiroApi } from '@mirohq/miro-api';

// High-level (OAuth-aware, stateful)
const miro = new Miro({ clientId, clientSecret, redirectUrl });
const userApi = await miro.as(userId);

// Low-level (stateless, pass token)
const api = new MiroApi(accessToken);
```

### Step 3: Migrate Widget Calls to Item Calls

```typescript
// BEFORE: Generic widget create
const widget = await client.createWidget(boardId, {
  type: 'sticker',
  text: 'Note content',
});

// AFTER: Type-specific item create
const stickyNote = await fetch(
  `https://api.miro.com/v2/boards/${boardId}/sticky_notes`,
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${token}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      data: { content: 'Note content', shape: 'square' },
      style: { fillColor: 'light_yellow' },
      position: { x: 0, y: 0 },
    }),
  }
);
```

### Step 4: Update Response Handling

```typescript
// v1 response: flat structure
// { id, type, text, x, y, width, style: { stickerBackgroundColor } }

// v2 response: nested structure
// {
//   id, type: 'sticky_note',
//   data: { content, shape },
//   style: { fillColor, textAlign },
//   position: { x, y, origin },
//   geometry: { width },
//   createdAt, modifiedAt, createdBy
// }

// Adapter for gradual migration
function adaptV2ToV1Shape(v2Item: any): any {
  return {
    id: v2Item.id,
    type: v2Item.type === 'sticky_note' ? 'sticker' : v2Item.type,
    text: v2Item.data?.content,
    x: v2Item.position?.x,
    y: v2Item.position?.y,
    width: v2Item.geometry?.width,
  };
}
```

### Step 5: Verify and Test

```bash
# Run tests
npm test

# Verify against a test board
MIRO_TEST_BOARD_ID=your-test-board npm run test:integration

# Check for any remaining v1 patterns
grep -r "widgets\|sticker\|startWidget\|endWidget\|shapeType" src/ --include="*.ts"
```

## v2 Response Pagination Change

```typescript
// v1: offset-based pagination
// GET /v1/boards/{id}/widgets?offset=100&limit=50

// v2: cursor-based pagination
// GET /v2/boards/{id}/items?limit=50&cursor=eyJ0...

async function getAllItemsV2(boardId: string): Promise<any[]> {
  const items: any[] = [];
  let cursor: string | undefined;

  do {
    const url = new URL(`https://api.miro.com/v2/boards/${boardId}/items`);
    url.searchParams.set('limit', '50');
    if (cursor) url.searchParams.set('cursor', cursor);

    const response = await fetch(url.toString(), {
      headers: { 'Authorization': `Bearer ${token}` },
    });
    const result = await response.json();
    items.push(...result.data);
    cursor = result.cursor;
  } while (cursor);

  return items;
}
```

## Error Handling

| Issue | Detection | Solution |
|-------|-----------|----------|
| `Cannot find module '@miro/sdk'` | Import error | Update to `@mirohq/miro-api` |
| `widgets is not a function` | SDK API change | Use per-type endpoints |
| `text` field undefined | v2 response shape | Access via `data.content` |
| Connector fails | v1 line syntax | Update to `startItem`/`endItem` |
| Position wrong | Flat vs nested | Wrap in `position: { x, y }` |
