Miro Web SDK

The Miro Web SDK enables you to build web plugins that extend Miro's functionality. Create custom tools, automate workflows, and integrate external data directly into Miro boards.

Quick Start

Install SDK:

npm install @mirohq/websdk-cli @mirohq/miro-webplugin

Create Plugin:

npm create @mirohq/websdk-cli my-plugin
cd my-plugin
npm start

Hello World Plugin:

import { Board } from '@mirohq/miro-webplugin';

miro.onReady(async () => {
  console.log('Plugin ready!');
  
  // Get current board
  const board = await miro.board.getInfo();
  console.log('Board name:', board.name);
  
  // Listen for shape creation
  miro.board.events.on('item:create', (event) => {
    console.log('New item:', event.data);
  });
});

Core Capabilities

1. Board Interaction

• Get board information (name, owner, size)
• Listen to real-time events (item creation, updates, deletions)
• Manage board selection and viewport
• Access board history and undo/redo

2. Create Items

• Shapes (rectangles, circles, diamonds, etc.)
• Text and rich text formatting
• Images and embeds
• Sticky notes and cards
• Frames and groups

3. Manipulate Items

• Move, resize, rotate items
• Change styling (colors, opacity, fonts)
• Update content and properties
• Apply connectors between shapes
• Delete items

4. Selection & Interaction

• Get selected items
• Listen to selection changes
• Programmatically select items
• Multi-select operations

5. User Interaction

• Viewport and zoom control
• Notification system
• Modal dialogs
• Context menus
• Keyboard shortcuts

6. Collaboration Features

• Real-time sync with other users
• User presence indicators
• Shared selections
• Live editing

7. Data Management

• Metadata and custom properties
• Board-level storage
• Plugin configuration
• Event tracking

8. Advanced Features

• Batch operations (bulk create/update)
• Search and filtering
• Viewport navigation
• Animation support
• Performance optimization

SDK Platforms

Web Plugin

Browser-based plugin running inside Miro app

Install:

npm install @mirohq/miro-webplugin

Use:

import { Board, Ui } from '@mirohq/miro-webplugin';

// Access board
const board = await miro.board.getInfo();

// Create UI
miro.ui.openPanel({
  url: 'panel.html'
});

Desktop App

Standalone desktop application using Electron

Install:

npm install @mirohq/miro-desktop

Supported Platforms:

• macOS
• Windows
• Linux

Authentication

Web Plugin Auth

Uses implicit flow - user already logged into Miro

miro.onReady(async () => {
  // User automatically authenticated
  const user = await miro.currentUser.get();
  console.log('Current user:', user.name);
});

Scopes

Define what your plugin can do:

{
  "requiredScopes": [
    "board:read",
    "board:write",
    "identity:read"
  ]
}

Available Scopes:

• board:read - Read board data
• board:write - Create/edit items
• board:history - Access history
• identity:read - Get current user info
