Effortlessly adding custom classes in Angular 2 with a breeze

Imagine having a growing Angular2 typescript solution with numerous small classes and objects. Following the best practice, each class is placed in its own file.

However, manipulating these objects leads to long lists of imports like:


import {Object1} from '../core-data/object1';
import {Object2} from '../core-data/object2';
import {Object3} from '../core-data/object3';
{Object4} from '../core-data/object4';
import {Object5} from '../core-data/object5';

It would be more convenient if you could simplify this process by importing all core objects at once:


import {Object1, Object2, Object3, Object4, Object5} from '../core-data/CORE_OBJECTS';

The attempt to replicate the pattern used by the Angular team for CORE_DIRECTIVES did not work as expected, as those are added through the directives property on the Component annotation.

You don't want to create a new project or bundle it together as it may complicate things - these are simply core objects that should be easy to adjust.

What would be the most effective way to address this issue?

One way to make the most of Angular2 is by using the export from feature.

Imagine you have a file called core.objects.ts:

export {ItemA} from '../core-data/itemA';
export {ItemB} from '../core-data/itemB';
export {ItemC} from '../core-data/itemC';
export {ItemD} from '../core-data/itemD';
export {ItemE} from '../core-data/itemE';

You can then utilize the core.objects module like this:

import {
  ItemA, ItemB, ItemC, ItemD, ItemE
} from '../core-data/core.objects';

Just wanted to share some additional insights I came across:

If you establish an index.ts within the /core-data directory and populate it with the following:

export * from './core-terms';

You can simplify your import statement like so:

import { Object1, Object2, Object3, Object4, Object5 } from '../core-data/';

There's no need to specify both the folder and the specific file containing the exports :)

UPDATE: It's important to note that this method still relies on having the core-terms.ts file with the necessary exports. One alternative is to directly export from core-terms.ts instead of using the extra file. Alternatively, as the core-data folder expands, you could create additional sub files and consolidate them all in the index.ts. This way, index.ts serves as a comprehensive collection of all classes, allowing for further categorization such as core-terms.ts, core-components.ts, core-whatever.ts...
