Supported aura:attribute Types
aura:attribute describes an attribute available on
an app, interface, component, or event.
| Attribute Name | Type | Description |
|---|---|---|
| access | String | Indicates whether the attribute can be used outside of its own namespace. Possible values are public (default), and global, and private. |
| name | String | Required. The name of the attribute. For example, if you set <aura:attribute name="isTrue" type="Boolean" /> on a component called aura:newCmp, you can set this attribute when you instantiate the component; for example,<aura:newCmp isTrue="false" />. |
| type | String | Required. The type of the attribute. For a list of basic types supported, see Basic Types. |
| default | String | The default value for the attribute, which can be overwritten as needed. When setting a default value, expressions using the $Label, $Locale, and $Browser global value providers are supported. Alternatively, to set a dynamic default, use an init event. See Invoking Actions on Component Initialization. |
| required | Boolean | Determines if the attribute is required. The default is false. |
| description | String | A summary of the attribute and its usage. |
All <aura:attribute> tags have name and type values. For example:
1<aura:attribute name="whom" type="String" />
