Implementing a custom directive in a non-standalone component
I have developed a custom structural directive and I would like to use it across multiple components. Everything functions as expected when it is not standalone, but encountering an error when adding standalone: true: 'imports' is only valid on a standalone component.
I prefer to keep my component non-standalone while making the directive standalone. Is there a solution for this dilemma?
How can I achieve this desired setup?
When dealing with a non-independent element, and you wish to apply an independent custom directive to it, you must import the directives into the module file, such as app.module.ts.
It is important to note that when your custom directives are independent, you should only import them without declaring.
The imports attribute within a @Component decorator is specifically for standalone elements. If your element is not standalone and you attempt to modify the imports attribute, you will encounter an error.
Standalone directives can be easily imported into your modules just like you import a module.
