Mapping sockjs-client in systemjs - node.js

Question

I'm using typescript and angular2 and I want to use SockJS in my project. I run: npm install sockjs-client. Now I want to add mapping of node_modules/sockjs-client in systemjs.config.js. It is how the file looks now:
/**
* System configuration for Angular 2 samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
'#angular/core': 'npm:#angular/core/bundles/core.umd.js',
'#angular/common': 'npm:#angular/common/bundles/common.umd.js',
'#angular/compiler': 'npm:#angular/compiler/bundles/compiler.umd.js',
'#angular/platform-browser': 'npm:#angular/platform-browser/bundles/platform-browser.umd.js',
'#angular/platform-browser-dynamic': 'npm:#angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'#angular/http': 'npm:#angular/http/bundles/http.umd.js',
'#angular/router': 'npm:#angular/router/bundles/router.umd.js',
'#angular/forms': 'npm:#angular/forms/bundles/forms.umd.js',
// other libraries
'rxjs': 'npm:rxjs',
'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
'sockjs-client': 'npm:sockjs-client',
'stompjs': 'npm:stompjs/lib/stomp.min.js'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular2-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);
And I've the following exception in the browser:
localhost/:16 Error: Error: XHR error (404 Not Found) loading http://localhost:8080/node_modules/sockjs-client(…)
What is the proper systemjs mapping for sockjs-client library?

Try:
'sockjs-client': 'npm:sockjs-client/dist/sockjs.js'
