What is the process for exporting a class to a module and then importing it into another module using TypeScript within an Angular environment?

I have a class called IGeneric that is exported to module A and imported into module B. However, I am unable to use this exported class in module B.

Please note that the exported class is not a component, directive, or service; it is a plain TypeScript class.

Any assistance would be greatly appreciated. Here is the class that I am attempting to export:


export class IGeneric {
    header: any[];
    content: [{
        label: any,
        value: any
    }]
}

One clever technique involves concealing module details through the use of barrel files, as explained in a helpful article on how to do so by barrel files. With this method, you can:

  • Add a barrel file (often named index.ts) to your module,
  • Export all desired elements within that barrel file, and then
  • Simply import the module path whenever you need to access the exported classes/interfaces or components.

For further insights, another informative post dives into the advantages gained from employing barrel files.

It seems like the issue you are facing is related to importing/exporting modules in ES6/Typescript rather than with the NgModule system. To resolve this, all you need to do is add an import statement at the top of your .ts file for the specific class you want to use, like so:

import { SpecialClass } from './path/to/definition';

After that, you can simply utilize the imported class within your component/service as needed.

public specialInstance: SpecialClass;

Answer №3

index document is a useful tool for concealing the complete path of your class.

Imagine you have a module named MyModule that contains a class called IGeneric.

igeneric.model.ts

export class IGeneric{
header : any[];
content : [{
   label :any,
   value :any
}]

The index file should reside within the directory of your Module MyModule.

index.ts

export * from 'app/MyModule/igeneric.model';

Subsequently, in your component, you can perform the import as follows:

import {IGeneric} from 'app/MyModule'
