Here is a scenario to consider
export class X{
y():void{}
z():void{}
}
I am currently in Module N I need to utilize method y() and z() within module N, but I want to restrict access to method y() from other modules while still allowing access to method z(). Is this achievable in Angular?
If your class represents a service, it's best to follow a structured approach.
You can create a base class that contains the common functionality for your service and then extend this class to implement different versions of the b() method. To prevent repeating the logic in the b() method, you can encapsulate it within a protected method in the base class and have both the public and private variations of b() call this method:
export class BaseService {
protected _b() {
return 'This string is from the b() method'
}
c() {
return 'This string is from the c() method'
}
}
@Injectable()
export class BaseServiceWithPublicB extends BaseService {
b() {
return super._b();
}
}
@Injectable()
export class BaseServiceWithPrivateB extends BaseService {
private b() {
return super._b();
}
}
Then you can provide BaseServiceWithPublicB in module M, and BaseServiceWithPrivateB in any other module:
@NgModule({
declarations: [],
providers: [{provide: BaseService, useClass: BaseServiceWithPublicB}],
exports: []
})
export class ModuleWithPublicB { }
@NgModule({
declarations: [],
providers: [{provide: BaseService, useClass: BaseServiceWithPrivateB}],
exports: []
})
export class ModuleWithPrivateB { }
