Publish angular2 module / component as npm package - node.js

Question

I would like to create my library in npm of Angular2 components (my generic grid, my generic buttons, etc.) and modules (my clients in grid module) but I can't find any working example online (I did find a few though, but it never works...
index.js :
export { PortalGridComponent } from './src/portal-grid/portal-grid.component';
Here is my package.config.json :
{
"name": "my-perso-components",
"version": "1.0.13",
"main": "index.js",
"scripts": {
"nbuild": "tsc index.ts --outDir ./lib",
"build": "tsc -p src/",
"build:watch": "tsc -p src/ -w",
"build:e2e": "tsc -p e2e/",
"serve": "lite-server -c=bs-config.json",
"serve:e2e": "lite-server -c=bs-config.e2e.json",
"prestart": "npm run build",
"start": "concurrently \"npm run build:watch\" \"npm run serve\"",
"pree2e": "npm run build:e2e",
"e2e": "concurrently \"npm run serve:e2e\" \"npm run protractor\" --kill-others --success first",
"preprotractor": "webdriver-manager update",
"protractor": "protractor protractor.config.js",
"pretest": "npm run build",
"test": "concurrently \"npm run build:watch\" \"karma start karma.conf.js\"",
"pretest:once": "npm run build",
"test:once": "karma start karma.conf.js --single-run",
"lint": "tslint ./src/**/*.ts -t verbose"
},

"rimraf": "^2.5.4",
"tslint": "^3.15.1",
"typescript": "~2.0.10"
},
"license": "ISC"
}
my tsconfig.json :
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": [ "es2015", "dom" ],
"noImplicitAny": true,
"outDir": "./lib",
"suppressImplicitAnyIndexErrors": true,
"typeRoots": [
"./node_modules/#types"
],
"types": [
"core-js"
]
}
}
and my project architecture looks like this :
- lib
- node_modules
- src
- app
- my-perso-grid
- my-perso-grid.component.ts
- my-perso-grid.html
- my-perso-grid.scss
- .npmignore
- index.ts
- package.json
- tsconfig.json
I then run tsc index.ts --outDir ./lib and do npm version patch , then npm publish.
My code is in npm for sure, I can then install it in another folder... However, I always get a 404 issue :
Error: (SystemJS) XHR error (404 Not Found) loading
http://localhost:3000/my-perso-components Error: XHR error (404 Not Found)
Which is weird, because I do have to autocompletion for the name of my component when I do the Import inside another component and no error shown !!
Any idea ? what can I try ? Do you have a recent and working tutorial to create, publish and use an npm package ?
Thanks a lot... will help a lot
