[RC0] How to import "xml2js"

Ionic Framework ionic-v3
1

After RC0 upgrade the xml2js import failed :

npm install xml2js --save
npm install @types/xml2js --save --save-exact

the code :

import xml2js from "xml2js";

@Injectable()
export class XMLDataService {
  constructor() {
    console.log(xml2js)
  }
}

ionic serve log me that no names are provided for module stream, string_decoder, events, timer…

[10:22:42]  bundle dev started ...

I still don’t know how to fix it…

After all, I uninstall xml2js and install x2js
if someone needs the procedure :

my ionic conf :

Cordova CLI: 6.2.0
Ionic Framework Version: 2.0.0-rc.0
Ionic CLI Version: 2.1.0
Ionic App Lib Version: 2.1.0-beta.1
OS: Windows 7 SP1
Node Version: v5.6.0

npm install :

npm install x2js --save
npm install @types/x2js --save-dev --save-exact

versions that I use :

"x2js": "3.0.1"
"@types/x2js": "0.0.27"

add declaration to the types index :

to add at the end of _./node_modules/@types/x2js/index.d.ts

declare module 'x2js' {
    export = X2JS;
}

code sample :

import X2JS from 'x2js';

let xml =  "MY XML STRING";
let parser : any = new X2JS();
let json = parser.xml2js(xml);
