Typescript: Cannot find module of my custom library

Question

The Question

Why isn't my ng2-orm package being imported (or being recognized by vscode) when I do import Config from 'ng2-orm';

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { Config } from 'ng2-orm'; // ng2-orm/Config won't work either

@NgModule({
  imports:      [ BrowserModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

DETAILS

I am endeavoring to build my own TS library for use in angular2 and ionic2. I have researched and searched and cannot seem to come up with why this is failing, and it might just be due to some sort of incompleteness on my part.

I get that it's just the start, but I would imagine that anything exported from inside the project should be accessible. Is there an ngModule definition I need maybe?

I am providing the package.json, some folder structure, gulp (so you can see it), and tsconfig.json

Everything compiles fine etc.

But when I install it on the angular quickstart, it says it cannot find ng2-orm when I try to import. I have everything barreled into the index.js, and the package is in the node_modules folder.

Am I missing something that systemjs.config.js needs? I'm not sure. I have a typings.json, but it's basically empty, maybe I'm missing something there?

index.ts

export * from './Config/Config';

Config/Config.ts

export class Config {
  public test(): boolean { return true; }
}

Definition Files

index.d.ts

export * from './Config/Config';

Config.d.ts

export declare class Config {
    test(): boolean;
}

package.json

Folder Structure

gulpfile.js

I am including this so you can see that my gulp puts code in dist/js, dist/definitions, and dist/maps

var gulp = require('gulp');
var ts = require('gulp-typescript');
var sourcemaps = require('gulp-sourcemaps');
var merge = require('merge2');

var tsProject = ts.createProject('tsconfig.json');

gulp.task('scripts', function() {
  var tsResult = tsProject.src()
    .pipe(sourcemaps.init())
    .pipe(tsProject());

  return merge([
    tsResult.dts.pipe(gulp.dest('dist/definitions')),
    tsResult.js
      .pipe(sourcemaps.write('../maps'))
      .pipe(gulp.dest('dist/js'))
  ]);
});

gulp.task('watch', ['scripts'], function() {
  gulp.watch('./src/**/*.ts', ['scripts']);
});

gulp.task('default', ['scripts', 'watch']);

tsconfig.json

For your ng2-orm library, try making the typings entry of package.json point to index.d.ts, which re-exports everything e.g.

"typings": "./dist/definitions/index.d.ts"
