# PR Description

# Add Embed Iframe Block Support

## Overview

This PR introduces a new `EmbedIframeBlock` to enhance content embedding capabilities within our editor. This block allows users to seamlessly embed external content from various providers (Google Drive, Spotify, etc.) directly into their docs.

## New Blocks

### EmbedIframeBlock

The core block that renders embedded iframe content. This block:

* Displays external content within a secure iframe
* Handles loading states with visual feedback
* Provides error handling with edit and retry options
* Supports customization of width, height, and other iframe attributes

### Supporting Components

* **EmbedIframeCreateModal**: Modal interface for creating new iframe embeds
* **EmbedIframeLinkEditPopup**: UI for editing existing embed links
* **EmbedIframeLoadingCard**: Visual feedback during content loading
* **EmbedIframeErrorCard**: Error handling with retry functionality

## New Store Extensions

### EmbedIframeConfigExtension

This extension provides configuration for different embed providers:

```typescript
/**
 * The options for the iframe
 * @example
 * {
 *   defaultWidth: '100%',
 *   defaultHeight: '152px',
 *   style: 'border-radius: 8px;',
 *   allow: 'autoplay; clipboard-write; encrypted-media; fullscreen; picture-in-picture',
 * }
 * =>
 * <iframe
 *   width="100%"
 *   height="152px"
 *   style="border-radius: 8px;"
 *   allow="autoplay; clipboard-write; encrypted-media; fullscreen; picture-in-picture"
 * ></iframe>
 */
export type IframeOptions = {
  defaultWidth?: string;
  defaultHeight?: string;
  style?: string;
  referrerpolicy?: string;
  scrolling?: boolean;
  allow?: string;
  allowFullscreen?: boolean;
};

/**
 * Define the config of an embed iframe block provider
 */
export type EmbedIframeConfig = {
  /**
   * The name of the embed iframe block provider
   */
  name: string;
  /**
   * The function to match the url
   */
  match: (url: string) => boolean;
  /**
   * The function to build the oEmbed URL for fetching embed data
   */
  buildOEmbedUrl: (url: string) => string | undefined;
  /**
   * Use oEmbed URL directly as iframe src without fetching oEmbed data
   */
  useOEmbedUrlDirectly: boolean;
  /**
   * The options for the iframe
   */
  options?: IframeOptions;
};

export const EmbedIframeConfigIdentifier =
  createIdentifier<EmbedIframeConfig>('EmbedIframeConfig');

export function EmbedIframeConfigExtension(
  config: EmbedIframeConfig
): ExtensionType & {
  identifier: ServiceIdentifier<EmbedIframeConfig>;
} {
  const identifier = EmbedIframeConfigIdentifier(config.name);
  return {
    setup: di => {
      di.addImpl(identifier, () => config);
    },
    identifier,
  };
}
```

**example:**

```typescript
//  blocksuite/affine/blocks/block-embed/src/embed-iframe-block/configs/providers/spotify.ts

const SPOTIFY_DEFAULT_WIDTH = '100%';
const SPOTIFY_DEFAULT_HEIGHT = '152px';

// https://developer.spotify.com/documentation/embeds/reference/oembed
const spotifyEndpoint = 'https://open.spotify.com/oembed';

const spotifyUrlValidationOptions: EmbedIframeUrlValidationOptions = {
  protocols: ['https:'],
  hostnames: ['open.spotify.com', 'spotify.link'],
};

const spotifyConfig = {
  name: 'spotify',
  match: (url: string) =>
    validateEmbedIframeUrl(url, spotifyUrlValidationOptions),
  buildOEmbedUrl: (url: string) => {
    const match = validateEmbedIframeUrl(url, spotifyUrlValidationOptions);
    if (!match) {
      return undefined;
    }
    const encodedUrl = encodeURIComponent(url);
    const oEmbedUrl = `${spotifyEndpoint}?url=${encodedUrl}`;
    return oEmbedUrl;
  },
  useOEmbedUrlDirectly: false,
  options: {
    defaultWidth: SPOTIFY_DEFAULT_WIDTH,
    defaultHeight: SPOTIFY_DEFAULT_HEIGHT,
    allow:
      'autoplay; clipboard-write; encrypted-media; fullscreen; picture-in-picture',
    style: 'border-radius: 12px;',
    allowFullscreen: true,
  },
};

// add the config extension to store
export const SpotifyEmbedConfig = EmbedIframeConfigExtension(spotifyConfig);
```

**Key features:**

* Provider registration and discovery
* URL pattern matching
* Provider-specific embed options (width, height, features)

### EmbedIframeService

This service provides abilities to handle URL validation, data fetching, and block creation

**Type:**

```typescript
/**
 * Service for handling embeddable URLs
 */
export interface EmbedIframeProvider {
  /**
   * Check if a URL can be embedded
   * @param url URL to check
   * @returns true if the URL can be embedded, false otherwise
   */
  canEmbed: (url: string) => boolean;

  /**
   * Build a API URL for fetching embed data
   * @param url URL to build API URL
   * @returns API URL if the URL can be embedded, undefined otherwise
   */
  buildOEmbedUrl: (url: string) => string | undefined;

  /**
   * Get the embed iframe config
   * @param url URL to get embed iframe config
   * @returns Embed iframe config if the URL can be embedded, undefined otherwise
   */
  getConfig: (url: string) => EmbedIframeConfig | undefined;

  /**
   * Get embed iframe data
   * @param url URL to get embed iframe data
   * @returns Embed iframe data if the URL can be embedded, undefined otherwise
   */
  getEmbedIframeData: (url: string) => Promise<EmbedIframeData | null>;

  /**
   * Parse an embeddable URL and add an EmbedIframeBlock to doc
   * @param url Original url to embed
   * @param parentId Parent block ID
   * @param index Optional index to insert at
   * @returns Created block id if successful, undefined if the URL cannot be embedded
   */
  addEmbedIframeBlock: (
    props: Partial<EmbedIframeBlockProps>,
    parentId: string,
    index?: number
  ) => string | undefined;
}
```

**Implemetation:**

```typescript
export class EmbedIframeService
  extends StoreExtension
  implements EmbedIframeProvider
{
  static override key = 'embed-iframe-service';

  private readonly _configs: EmbedIframeConfig[];

  constructor(store: Store) {
    super(store);
    this._configs = Array.from(
      store.provider.getAll(EmbedIframeConfigIdentifier).values()
    );
  }

  canEmbed = (url: string): boolean => {
    return this._configs.some(config => config.match(url));
  };

  buildOEmbedUrl = (url: string): string | undefined => {
    return this._configs.find(config => config.match(url))?.buildOEmbedUrl(url);
  };

  getConfig = (url: string): EmbedIframeConfig | undefined => {
    return this._configs.find(config => config.match(url));
  };

  getEmbedIframeData = async (
    url: string,
    signal?: AbortSignal
  ): Promise<EmbedIframeData | null> => {
    try {
      const config = this._configs.find(config => config.match(url));
      if (!config) {
        return null;
      }

      const oEmbedUrl = config.buildOEmbedUrl(url);
      if (!oEmbedUrl) {
        return null;
      }

      // if the config useOEmbedUrlDirectly is true, return the url directly as iframe_url
      if (config.useOEmbedUrlDirectly) {
        return {
          iframe_url: oEmbedUrl,
        };
      }

      // otherwise, fetch the oEmbed data
      const response = await fetch(oEmbedUrl, { signal });
      if (!response.ok) {
        console.warn(
          `Failed to fetch oEmbed data: ${response.status} ${response.statusText}`
        );
        return null;
      }

      const data = await response.json();
      return data as EmbedIframeData;
    } catch (error) {
      if (error instanceof Error && error.name !== 'AbortError') {
        console.error('Error fetching embed iframe data:', error);
      }
      return null;
    }
  };

  addEmbedIframeBlock = (
    props: Partial<EmbedIframeBlockProps>,
    parentId: string,
    index?: number
  ): string | undefined => {
    const blockId = this.store.addBlock(
      'affine:embed-iframe',
      props,
      parentId,
      index
    );
    return blockId;
  };
}
```

**Usage:**

```typescript
// Usage example
const embedIframeService = this.std.get(EmbedIframeService);

// Check if a URL can be embedded
const canEmbed = embedIframeService.canEmbed(url);

// Get embed data for a URL
const embedData = await embedIframeService.getEmbedIframeData(url);

// Add an embed iframe block to the document
const block = embedIframeService.addEmbedIframeBlock({
  url,
  iframeUrl: embedData.iframe_url,
  title: embedData.title,
  description: embedData.description
}, parentId, index);
```

**Key features:**

* URL validation and transformation
* Provider-specific data fetching
* Block creation and management

## Adaptations

### Toolbar Integration

Added toolbar actions for embedded content:

* Copy link
* Edit embed title and description
* Toggle between inline/card views
* Add caption
* And more

### Slash Menu Integration

Added a new slash menu option for embedding content:

* Embed item for inserting embed iframe block
* Conditional rendering based on feature flags

### Adapters

Implemented adapters for various formats:

* **HTML Adapter**: Exports embed original urls as html links
* **Markdown Adapter**: Exports embed original urls as markdown links
* **Plain Text Adapter**: Exports embed original urls as link text

## To Be Continued:
