Używam kątowego-cli do generowania nowego projektu. Teraz chcę dodać socketJs do projektu, ale zachować uzyskiwanie błędy w konsoli Przeglądarka:Jak dodać SockJS do projektu Angular 2?

To jest moje kroki i konfiguracja:
typings install sockjs-client --save --ambient
kątowe-CLI-build.js
var Angular2App = require('angular-cli/lib/broccoli/angular2-app');
module.exports = function(defaults) {
return new Angular2App(defaults, {
vendorNpmFiles: [
'systemjs/dist/system-polyfills.js',
'systemjs/dist/system.src.js',
'zone.js/dist/**/*.+(js|js.map)',
'es6-shim/es6-shim.js',
'reflect-metadata/**/*.+(ts|js|js.map)',
'rxjs/**/*.+(js|js.map)',
'@angular/**/*.+(js|js.map)',
'sockjs-client/**/*.+(js)'
]
});
};
System-config.ts
/** Map relative paths to URLs. */
const map: any = {
'sockjs-client': 'vendor/sockjs-client/lib/entry.js'
};
/** User packages configuration. */
const packages: any = {
'vendor/sockjs-client/lib': {
'format': 'cjs',
'defaultExtension': 'js'
}
};
niestandardowej klasy usługi:
import { Injectable } from '@angular/core';
import * as SockJS from 'sockjs-client';
import BaseEvent = __SockJSClient.BaseEvent;
import SockJSClass = __SockJSClient.SockJSClass;
@Injectable()
export class WebsocketService {
private sockJs: SockJSClass;
constructor() {
console.log('constuctor');
this.sockJs = new SockJS('/hello');
}
}
Proszę dać mi znać, jak go naprawić, dzięki dużo!
Mogę jednak wyeliminować błąd poprzez dodanie brakującej biblioteki, dodając je po kolei w system-config.ts. Ale wątpię, czy to właściwe podejście.
const map: any = {
'sockjs-client': 'vendor/sockjs-client/lib/entry.js',
'json3': 'vendor/sockjs-client/node_modules/json3/lib/json3.js',
'url-parse': 'vendor/sockjs-client/node_modules/url-parse/index.js',
'inherits': 'vendor/sockjs-client/node_modules/inherits/inherits.js',
'debug': 'vendor/sockjs-client/node_modules/debug/debug.js',
...
};
nie wydaje się w katalogu node_module? –
