Import component from a different repo

Question

I created a repo in bitbucket which called "angular-lister", the structure of the repo is:

Then I created another repo which have the same structure (sort of, cant put picture here and it doesnt really matter).
In this second repo I installed my repo using npm i --save path/to/angular-lister.git and I saw it was added to my package json + it's located under my node_modules folder.

I am trying to import a component from angular-lister (app/app.component) but I am unable to do it.

This is my app.module.ts of the second repo (NOT angular-lister):

import { ListerAppComponent } from 'node_modules/angular-lister/app/app.component'

@NgModule({
    imports:      [
        ...
    ],
    declarations: [
        ...,
        ListerAppComponent
    ],
    bootstrap:    [ ...]
})

and I get the following error:

zone.js:1382 GET http://localhost:3000/node_modules/angular-lister/app/app.component 404 (Not Found)

Why is that, what am I doing wrong here?

node_modules/agnular-lister:

Can you show the contents of 'node_modules/angular-lister/', your systemjs.config.js and the package.json for angular-lister? — JayChase, Dec 10 '16 at 01:29
@JayChase added what you asked for, this is what I currently have (I've tried Sakuto solution and reverted what I did because it didnt work). — Ron, Dec 10 '16 at 11:24
I would have to agree with Sakuto that creating a library module is the way forward. I have a post on it (along with links to a sample repo) [here](http://www.usefuldev.com/blog/post/using-ngc-to-build-an-angular-2-library-project). Note this approach uses the [compiler-cli](https://github.com/angular/angular/tree/master/modules/@angular/compiler-cli) which is needed it you want to use AoT. — JayChase, Dec 13 '16 at 03:28

node_modules should not be there since you are already telling SystemJS to check in that folder. Just edit it by this:

import { ListerAppComponent } from './angular-lister/app/app.component'

Keep in mind that you can't just import the project, you have to create a npm package and export the right thing. this tutorial is a good entrypoint to understand how it works.

when I change it, it says: `http://localhost:3000/angular-lister/app/app.component 404 (Not Found)` do I need to do something in SystemJS? – Ron Dec 02 '16 at 13:50
In your node module, what's the structure of your angular-lister folder? – LoïcR Dec 02 '16 at 13:54
node_modules/angular-lister/... where `...` is the same as the picture above. If I navigate to `http://localhost:3000/node_modules/angular-lister/app/app.component.js` the file exists.. – Ron Dec 02 '16 at 13:57

You can't just "import" a full project, check this [link](https://medium.com/@OCombe/how-to-publish-a-library-for-angular-2-on-npm-5f48cdabf435#.jkkb3y8qz) to understand how to create a A2 package – LoïcR Dec 02 '16 at 13:59
Alright, I will read it and see if it helps. Is this updated enough to understand? I can see it was published in Oct 15 – Ron Dec 02 '16 at 14:02
Well, you do not need typings to make it works, nor updating the systemjs.config, otherwise it's fine – LoïcR Dec 02 '16 at 14:04
I followed the instuctions - created a file in the root of my project (angular-lister) with export of my component and etc.. but I was unable to use it. is there a live example where I can see and understand what's going on? – Ron Dec 03 '16 at 13:31
