When working with Angular, consider having both module A and module B. If I intend to utilize "A-component" within components of module B, what is the distinction between importing module A in Module B compared to including the "A-component" in the exports of module A?
I experimented with both methods, and it appears they do not yield the same result. This situation can be quite perplexing.
In order to achieve proper functionality, it is crucial to export and import multiple components, not just one at a time.
If default exports are not in use, the code should be structured as follows:
Component A (a.mjs)
export class myClass {
...
}
Component B (b.mjs)
import { myClass as myClassFromA } from './a.mjs'
Alternatively, if default exports are employed:
Component A (a.mjs)
export default class myClass {
...
}
Component B (b.mjs)
import myClassFromA from './a.mjs'
Angular relies on the concept of Dependency Injection. So, when you want to utilize A-component from B-module in Angular, it is essential to make sure that A-component is exported from A-module and also imported into B-module.
But what happens if you try to use A-component directly without exporting it?
In such a scenario, you would have to manually provide all dependencies of A-component in B-module, which is not considered as good coding practice. Therefore, it is recommended to always export components from their respective modules for better code organization.
