Use Interface with different namespaces in typescript

Question

I want to create an interface in 'parent.a' namespace and I want to use that interface in 'parent' namespace.

Is there any way to do that, please help me on this.

I have found one solution to access classes from different namespaces access class from namespace but I need to work with interface not classes.

my example:

module Parent.AInterface {    

    export interface AInterface {
        setParent(): void;
    }

}

My other module

module Parent {

    export class ParentClass implements AInterface {

    }

}

while doing so.. I'm getting an error that says Cannot find name 'AInterface'

please help me on this.

Are both modules declared in different files? If so, have you tried adding something like this ´///<reference path='pathToFile/first_file.ts'/>´ in the second class i.e. module Parent... ? — iberbeu

You should mention module name before interface name:

module Parent.AInterface {    

    export interface AInterface {
        setParent(): void;
    }

} 


module Parent {

    export class ParentClass implements AInterface.AInterface {
        setParent() {
        }
    }

}

This works fine for me in the typescript playground.

Parent.ts

///<reference path="./Parent.AInterface.ts" />
module Parent {
     export class ParentClass implements AInterface.AInterface {}
}
