angular component with attribute selector
You googled this because you're probably confused.
Yes, both components and directives can be used via angular's attribute
selector: { selector: '[my-attribute]' }
Generally, when should I use it with components?
- To not be restricted by speciication rules: <tr> must be a direct child of
<tbody> by the spec, you can encapsulate the rows of a table in a component via
attribute selector, for example.
<tbody>
<tr *ngFor="let dataRow of data" my-attribute [data]="data"></tr>
</tbody>
