##### width

This props defines the width of the Excalidraw component. Defaults to `window.innerWidth` if not passed.

##### height

This props defines the height of the Excalidraw component. Defaults to `window.innerHeight` if not passed.

##### initialData

This helps to load Excalidraw with `initialData`. Defaults to `[]`.
This should be array of [ExcalidrawElement[]](https://github.com/excalidraw/excalidraw-embed/blob/58178c388ae577140a1c679b5733f33e3722498a/src/element/types.ts#L44) as shown below.

```javascript
[
  {
    type: "rectangle",
    version: 141,
    versionNonce: 361174001,
    isDeleted: false,
    id: "oDVXy8D6rom3H1-LLH2-f",
    fillStyle: "hachure",
    strokeWidth: 1,
    strokeStyle: "solid",
    roughness: 1,
    opacity: 100,
    angle: 0,
    x: 100.50390625,
    y: 93.67578125,
    strokeColor: "#000000",
    backgroundColor: "transparent",
    width: 186.47265625,
    height: 141.9765625,
    seed: 1968410350,
    groupIds: [],
  },
];
```

You might want to use this if you are using some backend to store the excalidraw elements and want to preload excalidraw with those elements.

##### onChange

Every time component updates, this callback if passed will get triggered and has the below signature.

```javascript
onChange(ExcalidrawElement[], AppState)
```

Here you can try saving the data to your backend or local storage for example.

##### options

These contains the options object with which you can control the initial rendering of Excalidraw.
Currently it only contains the below keys, more to be added in future.

| Name                | type    | default | Description                        |
| ------------------- | ------- | ------- | ---------------------------------- |
| zenModeEnabled      | boolean | false   | Decides whether to enable zen mode |
| viewBackgroundColor | string  | #fff    | The background color of Excalidraw |

Here is how you use it

```javascript
{ zenModeEnabled: true, viewBackgroundColor: "AFEEEE" }
```

##### user

This is the user name which shows during collaboration. Defaults to `{name: ''}`. This is Object as later more attributes like user cursor colors can also be added.

##### onUsernameChange

This callback if passed gets triggered whenever username changes and has the below signature

```javascript
onUserNameChange(username);
```
