## Fields

### `size`

The size of the blob data in bytes.

```lua highlight={9} theme={null}
type DrawBlob = {
    myBlob: Blob?,
}

function init(self: DrawBlob, context: Context): boolean
    self.myBlob = context:blob('myBlob')

    if self.myBlob then
        print('Blob size:', self.myBlob.size, 'bytes')
    end

    return true
end

return function(): Node<DrawBlob>
    return {
        myBlob = nil,
        init = init,
    }
end
```

### `name`

The name of the blob asset.

```lua highlight={9} theme={null}
type DrawBlob = {
    myBlob: Blob?,
}

function init(self: DrawBlob, context: Context): boolean
    self.myBlob = context:blob('myBlob')

    if self.myBlob then
        print('Blob name:', self.myBlob.name)
    end

    return true
end

return function(): Node<DrawBlob>
    return {
        myBlob = nil,
        init = init,
    }
end
```

### `data`

The raw binary data as a buffer.

```lua highlight={9} theme={null}
type DrawBlob = {
    myBlob: Blob?,
}

function init(self: DrawBlob, context: Context): boolean
    self.myBlob = context:blob('myBlob')

    if self.myBlob then
        print('Blob data buffer:', self.myBlob.data)
    end

    return true
end

return function(): Node<DrawBlob>
    return {
        myBlob = nil,
        init = init,
    }
