How to use this module on my Ionic project? - ionic-framework

Question

I am just starting using Ionic framework recently. I have been trying to import this vcard module.
https://github.com/Heymdall/vcard
I am able to use it in normal javascript environment, but so far I am not able to use it in my .ts file.
What I have done are:
Adding the module using
npm install vcard-parser --save
npm install ajv#>=5.0.0 --save
Import it inside .ts file
import * as v from 'vcard-parser'
Then this is the result from console.log(v)
Object {}
proto
:
Object
constructor
:
function Object()
hasOwnProperty
:
function hasOwnProperty()
isPrototypeOf
:
function isPrototypeOf()
propertyIsEnumerable
:
function propertyIsEnumerable()
toLocaleString
:
function toLocaleString()
toString
:
function ()
valueOf
:
function valueOf()
defineGetter
:
function defineGetter()
defineSetter
:
function defineSetter()
lookupGetter
:
function lookupGetter()
lookupSetter
:
function lookupSetter()
get proto
:
function proto()
set proto
:
function proto()
I don't know how to use the module, such as calling function "parse" or "generate".
Could anybody please help me with an example please?

Answer 1

So their documentation on the install is not quite correct.
npm install vcard-parser
should change to
npm install vcard-parser --save
To save it to your package.json
I not 100% but it does not look like the code conforms to the component -> module pattern ( might be wrong here, just looks a bit different )
For most ionic/angular extentions/components you want to import it in your app.module.ts using the name declared in the package.json.
for example ionic-network would be
import { Network } from '#ionic-native/network';
Because in the package.json it is declared as a dependency as
"#ionic-native/network": "^4.1.0",
You can also import for a specific page and add it to the constructor.
Here is a post from the official documentation on installing 3rd party libraries

Based on how is vcard-parser tested, it should be like this:
declare var require: any;
var vCard = require('vcard-parser').vCard;
vCard.parse(raw);
