Including node-uuid package in Ionic 2 application - ionic2

Question

I'm building an Ionic 2 (RC0) application and I'm trying to use node-uuid by following the official documentation.
I've done:
$ npm install --save node-uuid
$ npm install --save #types/node-uuid
node-uuid seems to be using the default export approach, so I'm importing it in my typescript file like this:
import uuid from 'node-uuid';
And using it as follows:
console.log(uuid.v4);
However, my app doesn't come up and I see this error in the logs:
TypeError: des$3 is undefined
What am I missing?
Most resources for Angular 2 recommend using the typings CLI to install the type definitions, but this made no difference for me. I tried:
$ npm install --global typings
$ typings install --save node-uuid
$ ionic info

Please note that node-uuid is deprecated. They merged with another project and now it's only called uuid. Everything up to the point of installing the #types library is correct. (note that you will have to redo those steps using just 'uuid' not 'nod-uuid')
However,
console.log(uuid.v4);
does not generate an id. As per the documentation you need to specify in your import which version of uuid you want to use and then call your variable as a method: uuid();
From docs: [Deprecation warning: The use of require('uuid') is deprecated and will not be supported after version 3.x of this module. Instead, use require('uuid/[v1|v3|v4|v5]') as shown in the examples below.]
Here is a code example using uuid/v1:
import { Component } from '#angular/core';
import uuid from 'uuid/v1'; //here change 'v1' with the version you desire to use
#Component({
selector: "page-uuid",
templateUrl: "uuid.html"
})
export class uuidTestPage {
id = uuid();
constructor() {
console.log(this.id); // outputs id. For example: 298da400-1267-11e8-a6e5-3148ee6706e9
}
}
After you serve your app and enter the uuidTestPage you should see the id logged to the console. The format of the id will vary depending on the version you use:
Version 1 (timestamp): my example.
Version 3 (namespace)
Version 4 (random)
etc...
Happy coding!

Answer 2

you can try it: (angular2-uuid)
npm install angular2-uuid --save
......
import { UUID } from 'angular2-uuid';
...
let uuid = UUID.UUID();
it works on angular 2 & ionic 2
