Embed

Embed

The embed item enables embedding, displaying, and accessing content from an external source inside a Miro board.

To embed content from a supported provider in a board, specify:

• The URL pointing to the resource that you want to embed in a board.
• (Optional):
  • x and y board coordinates where you want the content to be embedded.
  • width and height of the embed area.
    If you don't explicitly set any dimensions, width and height are are calculated automatically, based on the actual dimensions and the aspect ratio of the resource.
    If width and height values aren't available, a default embed preview placeholder is displayed on the board.
  • A URL pointing to an image to use as a preview for the embed item.
  • How to display the content in the embed item: either directly on the board, or inside a modal overlay on the board.

ℹ️ Note:

• It's possible to initially set url, but it's not possible to update it.

Example:

const embed = await miro.board.createEmbed({
  url: 'https://youtu.be/HlVSNEiFCBk',
  previewUrl:
    'https://miro.com/blog/wp-content/uploads/2020/10/organize-their-Miro-boards-for-trainings-and-workshops-FB.png',
  mode: 'modal',
  width: 1280,
  height: 720,
  x: 1600,
  y: 1600,
});

// Output the created item to the developer console
console.log(embed);

Embed item example:

Figure 1. Example of an embed item with a playable YouTube video and an assigned preview image.

Properties

mode

'inline' | 'modal'

Defines how the content in the embed item is displayed on the board.

Possible values:

• inline: the embedded content is displayed directly on the board.
• modal: the embedded content is displayed inside a modal overlay on the board.

Default: inline

previewUrl

string

A valid URL pointing to an image available online or representing the image. Supported formats:

• A publicly available absolute URL to an image.
  For example: https://amazing-images.com/categories/cats/cute-fluffy-kitten.png
• Experimental feature A base64-encoded data URL: data:image/<image-file-format>;base64,<base64-encoded-image>.
  For example: data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEASABIAAD/4gIcSUNDX...

Supported transport protocols:

• HTTP
• HTTPS

Supported image file formats:

• BMP
• GIF
• JPG, JPEG
• PNG
• PSD
• SVG (SVG will be sanitized)

ℹ️ Note:

• Relative URL paths pointing to local assets, such as /path/to/local-image.png, are not supported. As a workaround:
  • Use REST API to upload a local image to Miro.
  • Experimental feature Encode a local image to a base64 data URL string, and then assign it to url.
• When updating the preview URL, either by using data URL or a publicly available absolute URL, the current size and aspect ratio of the existing image item in the board is preserved. The new source will be adjusted to the existing container following the same strategy applied when updating the image from the UI.

url

readonly string

A valid URL pointing to the resource that you want to embed on the board.

It's possible to embed external content from hundreds of content providers via the Embedly service.

The transport protocol must be HTTPS.

ℹ️ Note:

• It's possible to initially set url, but at the moment it's not possible to update it.

id

readonly string

Unique ID of the item, assigned automatically upon creation.

Example: 3658432978520043388

x

number

The x-axis coordinate of an item is the horizontal distance in dp of the center point of the item from the center point of the board.

The center point of the board has x: 0 and y: 0 coordinates.

Default: 0

See also:

• Board coordinates
• x and y: -Infinity

y

number

The y-axis coordinate of an item is the vertical distance in dp of the center point of the item from the center point of the board.

The center point of the board has x: 0 and y: 0 coordinates.

Default: 0

See also:

• Board coordinates
• x and y: -Infinity

type

readonly 'embed'

Defines the type of item.
Item type is useful to retrieve specific items from a board. For example, you can fetch all card and shape items from the board, and then carry out an action on them.

Example:

// Get all items from the board
const items = await miro.board.get();

// Count all card and shape items on the board
let cards = 0;
let shapes = 0;

items.forEach((items) => {
  switch (items.type) {
    case 'card':
      cards++;
    case 'shape':
      shapes++;
  }
});

// Output to the console the total amount of card and shape items
console.log(`The current board has ${cards} cards and ${shapes} shapes.`);

parentId

readonly 'null' | string

If an item is a child of another item, the child's parentId returns the unique identifier of the corresponding parent item.
If an item has no parent, its parentId is null.

You can use the value to retrieve a tree structure when items are nested inside containers.
For example, sticky notes inside frames or text items inside mindmaps.

origin

'center'

origin marks:

• The positioning reference point of a board item.
  This is the point used to calculate the x and y coordinates of an item when it's positioned on the board, or when it's a child inside a parent item.
• The rotation pivot point of a board item that supports rotation.

origin accepts only one value: center.
Any other value throws an error.

relativeTo

'canvas_center' | 'parent_top_left' | 'parent_center'

The relativeTo property affects the x and y coordinate values of a board item.
relativeTo defines the positioning reference of a board item, which can be:

• Relative to the board
• Relative to a parent item

Depending on whether an item is a child of a parent item or not, relativeTo can have one of the following values:

Value	Description	On the board UI
canvas_center	The item is positioned on the board, and it's not a child of another item. The x and y coordinate values of the item are relative to the center of the board.	Figure 1. The relativeTo property of the board item—a sticky note in the example image—is set to canvas_center. The same mechanism applies to and works in the same way for all supported board items.
parent_top_left	The item is positioned on the board, and it is a child of a parent item. For example, a parent frame. The x and y coordinate values of the child item are relative to the top-left corner of the parent item).	Figure 2. The relativeTo property of the board item—a sticky note in the example image—is set to parent_top_left. The same mechanism applies to and works in the same way for all supported board items.
parent_center	Experimental feature The item is positioned on the board, and it is a child of a parent mind map node. The x and y coordinate values of the item are relative to the center of the parent mind map node item.	Figure 3. The relativeTo property of the child mind map nodes is set to parent_center.

• Position and coordinates
• Children inside parent items

linkedTo?

string

linkedTo is the namespace that enables links to be associated to items on the board.

When this property is utilized, the associated item will display an arrow icon on its top right corner. On click, this icon will navigate to the associated link.

For links that point to another item on the same board, the viewport will automatically move to that item when true is returned.

For links that point to an item on a separate board or an external url, a new tab tab will be opened.

Note: Items of type tag do not support the linkedTo property.

To link an item to another item on the same board, a valid url with an item id must be specified:

const [geoCard] = await miro.board.get({type: 'card'});

const widgetId = `00000000000000000`;
const boardId = 'xxxxxxxxxxx';

// Generate url based on boardId and widgetId
geoCard.linkedTo = `https://miro.com/app/board/${xxxxxxxxxxx}/?moveToWidget=${widgetId}`;

// OR you can use relative URL
geoCard.linkedTo = `/app/board/${xxxxxxxxxxx}/?moveToWidget=${widgetId}`;

// OR you can generate url based on current URL by simply change of query param
const searchParams = new URLSearchParams(window.location.search);
searchParams.set('moveToWidget', widgetId);
const newRelativePathQuery = `${window.location.pathname}?${searchParams.toString()}`;
geoCard.linkedTo = newRelativePathQuery;

To unlink an item to the provided url, set the property to undefined or pass an empty string "":

const [geoCard] = await miro.board.get({type: 'card'});
// Unlink the widget
geoCard.linkedTo = '';
// or
geoCard.linkedTo = undefined;

await geoCard.sync();

console.log(geoCard.linkedTo); // will return empty string: ''

Methods

sync

() => Promise<void>

🔒 Requires scope: boards:write

sync propagates to the board any changes to item and tag properties.
After updating the properties of an item or a tag, sync it with the board to:

• Propagate to the board the changes applied to the item or to the tag.
• Make the changes visible on the board.

All board items and tags require sync to make any changes to their properties visible on the board.

For more information and examples, see Update and sync item properties.

Example:
(The code example updates a text item using sync.
The same mechanism applies to and works in the same way for all supported board items.)

// Create an item.
// In this case, a text item.
const text = await miro.board.createText({
  content: '<p>This is a piece of text to remind me that I always finish what I ...</p>',
  style: {
    fillColor: 'transparent',
    textAlign: 'left',
  },
  x: 0,
  y: 0,
  width: 450,
  rotation: 0.0,
});

// Update the board item by modifying the values of its properties.
// In the text item case, the updated properties modify content, background color, and rotation of the item.
text.content = 'A fourteneer is "A line that rumbles on like this for being a bit too long."';
text.style.fillColor = '#a9fe65';
text.rotation = 180.0;

// Call 'sync' to make the changed board item properties visible on the board.
await text.sync();

// Output the updated board item to the developer console.
console.log(text);

Example:
(The code example updates a tag using sync.
The same mechanism applies to and works in the same way for all supported board items.)

// Create a tag.
const todo = await miro.board.createTag({
  title: 'todo',
  color: 'yellow',
});

// Create a sticky note and attach the tag to it.
const stickyNote = await miro.board.createStickyNote({
  content: 'sticky note with tag: "todo"',
  tagIds: [todo.id],
});
console.log(stickyNote.tagIds); // => ['3074457345627244742']

// Update the tag properties: title and color.
todo.title = "won't fix";
todo.color = 'green';

// Call 'sync' to make the changed tag properties visible on the board.
await todo.sync();

// Output the updated tag to the developer console.
console.log(todo);

getMetadata

(key: string) => Promise<T>

🔒 Requires scope: boards:read

🚦 Rate limit: Level 1

Fetches board item metadata, stored per app, for the specified metadata key.
The response contains the metadata value assigned to the requested key.

To fetch all the metadata for a board item, invoke the method without passing any arguments.
The response contains all the metadata associated with the board item as key/value pairs.

An app can access only the metadata that it sets.
It cannot access metadata set by other apps.

getMetadata and setMetadata are available for the following board items:

• Card
• Connector
• Embed
• Image
• Preview
• Shape
• Sticky note
• Text

The methods aren't available for the following board items:

• Frames
• Unsupported board items
• groups

ℹ️ Note:

• To access board item metadata, apps require the boards:read permission.
• To store board item metadata, apps require the boards:write permission.
• getMetadata returns a new object, not a reference to the object that was previously set with setMetadata.
• If the specified key isn't found, the method returns undefined.

⚠️ Warning:

• Total ItemMetadata storage limit: 6 KB per item.

Example:

// Get the board item you want to retrieve metadata from.
const [geoCard] = await miro.board.get({type: 'card'});

// Set item metadata for an imaginary geocaching game, and store it to the retrieved card item.
await geoCard.setMetadata('leaderboard', ['Ziltoid', 'Howard', 'Paul']);

// Get the specific 'leaderboard' metadata from the card item.
const leaderboard = await geoCard.getMetadata('leaderboard');

// Get all the metadata from the card item by passing no arguments.
await geoCard.getMetadata();

setMetadata

(key: string, value: title="Json">Json) => Promise<T>

🔒 Requires scope: boards:write

Adds board item metadata to make it available on the board that the app runs on.
An app can access only the board item metadata that it sets.
It cannot access metadata set by other apps.

Board item metadata is stored in the item it refers to. Therefore:

• When duplicating an item, the metadata is copied to the new item.
• When deleting an item, the corresponding metadata is removed with the deleted item.

Board item metadata is synced across, and available to, all the users who can:

• Access and view the board that the app is running on, AND
• Run the app on the board.

ItemMetadata is a key/value-pair object. It can contain values with the following data types:

• string
• number
• boolean
• Object
• Array
• null
• undefined

getMetadata and setMetadata are available for the following board items:

• Card
• Connector
• Embed
• Image
• Preview
• Shape
• Sticky note
• Text

The methods aren't available for the following board items:

• Frames
• Unsupported board items
• groups

To overwrite an existing key inside ItemMetadata:

• Pass the same key multiple times with different values. Only the last/most recent value is stored with the key.

To remove a key from ItemMetadata:

• Set the value of the existing key to either null, or undefined.
  This clears the key. If you call getMetadata(key) to retrieve a key that has been set to null or undefined, the method returns undefined.

ℹ️ Note:

• To access board item metadata, apps require the boards:read permission.
• To store board item metadata, apps require the boards:write permission.
• You can assign an empty array ([]) to a key. It's returned as an empty array.
• You can assign an empty string ('') to a key. It's returned as an empty string.

⚠️ Warning:

• Total ItemMetadata storage limit: 6 KB per item.

Example:

// Get the board item you want to set metadata to.
const [geoCard] = await miro.board.get({type: 'card'});

// Set item metadata for an imaginary geocaching game, and store it to the retrieved card item.
await geoCard.setMetadata('geoData', {
  name: 'null',
  coordinates: {
    latitude: '33.950278',
    longitude: '-105.314167',
  },

    },
  ],
});

// Get the specific 'geoData' metadata from the card item.
// The response contains the metadata value assigned to the key.
const geoCardGeoData = await geoCard.getMetadata('geoData');

// Get all the metadata from the card item.
// The response contains all the metadata assigned to the board item as key/value pairs.
const geoCardAllMetaData = await geoCard.getMetadata();

// Clear the metadata about the imaginary geocaching game in one of the following ways:
// 1. Assign 'geoData' an empty object.
await miro.board.setMetadata('geoData', {});
// 2. Set 'geoData' to 'undefined'.
await miro.board.setMetadata('geoData', undefined);
// 3. Set 'geoData' to 'null'.
await miro.board.setMetadata('geoData', null);

goToLink

() => Promise<boolean>

🔒 Requires scope: boards:read

goToLink navigates to the provided link associated with the item on a board.

For links that point to another item on the same board, the viewport will automatically move to that item when true is returned.

For links that point to an item on a separate board or an external url, a new tab tab will be opened.

Returns:

Promise<boolean>

• true: Link is successfully associated with the item, navigation is triggered, and the linkedTo property contains a valid value.
• false: Link is not successfully associated to the item due to an invalid or missing linkedTo property, and no navigation is triggered.

Example:

const [geoCard] = await miro.board.get({type: 'card'});

// Link item to some url
geoCard.linkedTo = 'https://google.com';

// Update widget props and apply changes
await geoCard.sync();

// Navigate to https://google.com (value of `linkedTo` property)
await geoCard.goToLink();

bringToFront

() => Promise<void>

🔒 Requires scope: boards:write

🚦 Rate limit: Level 1

In a stack of items, this method brings an item to the front so that it is at the top of the stack.
When the item is at the front, it is fully visible; The item can partially or completely hide underlying items in the same stack.

ℹ️ Note:

• Frame items don't support the bringToFront() method.
  As a frame item acts as a parent that can contain other items, a frame item is always at the back, relative to any other items on the board.
  The only object behind a frame is the board itself.

Example:

// Create three sticky notes
const first = await miro.board.createStickyNote({
  content: 'first',
});

const second = await miro.board.createStickyNote({
  content: 'second',
});

const third = await miro.board.createStickyNote({

// Bring the first sticky note to the front of the board.
await first.bringToFront();

sendToBack

() => Promise<void>

🔒 Requires scope: boards:write

🚦 Rate limit: Level 1

In a stack of items, it sends an item to the back so that it is at the bottom of the stack.
When it is at the back, item is partially or completely hidden by overlying items in the same stack.

ℹ️ Note:

• Frame items don't support the sendToBack() method.
  As a frame item acts as a parent that can contain other items, a frame item is always at the back, relative to any other items on the board.

bringInFrontOf

(target: BaseItem) => Promise<void>

🔒 Requires scope: boards:write

🚦 Rate limit: Level 1

In a stack of items, this method sends an item in front of another item (target).
When an item is moved to the front, the item can partially or completely hide underlying items in the same stack.

ℹ️ Note:

• As this method implements relative positioning, you can use this method to place items in front or behind other items.
  If you want to send an item all the way to the front,
  you can use the method bringToFront(), which places the item at the top of the stack.
• Frame items don't support the bringInFrontOf() method.
  As a frame item acts as a parent that can contain other items, a frame item is always at the back, relative to any other items on the board.
  The only object behind a frame is the board itself.

Example:

// Create three sticky notes

🔒 Requires scope: boards:write

🚦 Rate limit: Level 1

In a stack of items, this method sends an item behind another item (target).
When an item is moved to the back, the item can be partially or completely hidden by the overlying items in the top of the same stack.

ℹ️ Note:

• As this method implements relative positioning, you can use this method to place items in front or behind other items.
  If you want to send an item all the way to the back,
  you can use the method sendToBack(), which places the item at the bottom of the stack.

const third = await miro.board.createStickyNote({
  content: 'third',
});

// Send the third sticky note behind the second one
await third.sendBehindOf(second);

getLayerIndex

() => Promise<number>

🔒 Requires scope: boards:read

The getLayerIndex() method returns the position of an item in the item stack.

Items in a stack are layered on top of each other based on their layer index value. An item with a higher layer index appears above items with lower layer index values.

Each item on the board has a layer index position in the stack. The higher the layer index value, the "closer" to the user the item appears.

For example, with three items on the board - first, second, and third - their initial layer index values might be:
first[0], second[1], third[2].

The item with layerIndex === 2 (third) will be fully visible at the top of the stack. The item with layerIndex === 1 (second) may be partially hidden by the item above it. And the item with layerIndex === 0 (first) may be fully hidden by the items above it.

Returns:

• Promise<number> - calling getLayerIndex() allows you get the position of a specific item in the stack.

ℹ️ Note:

• The item stack is zero indexed.
• Frame items don't support the getLayerIndex() method.
  As a frame item acts as a parent that can contain other items, a frame item is always at the back, relative to any other items on the board.
  The only object behind a frame is the board itself.

Example:

// Create three sticky notes.
// Sticky notes are created on top of each other in the creation order, with the layer index equal to the creation index.
const first = await miro.board.createStickyNote({
  content: 'first',
});

const second = await miro.board.createStickyNote({
  content: 'second',
});

const third = await miro.board.createStickyNote({
  content: 'third',
});

await third.getLayerIndex(); // returns 2

getConnectors

() => Promise<Array<Connector>>

🔒 Requires scope: boards:read

🚦 Rate limit: Level 3

The getConnectors() method returns an array of connector items attached to the current item. The connectors returned correspond to the ids in the connectorIds property of the item.

Example:

// Create two sticky notes linked by a connector.
const startItem = await miro.board.createStickyNote({
  content: 'start',
});

const endItem = await miro.board.createStickyNote({
  content: 'end',
  x: 500,
});

const connector = await miro.board.createConnector({
  start: {
    item: startItem.id,
