Import Vanilla JavaScript library in Angular 6

Question

I am getting following error when try to import existing Vanilla JavaScript library to Angular 6 component. Please suggest how to fix it.

Syntax to import the library, I have written

import * as ExistingLibrary from 'app/main/libs/ExistingLibrary.js';

ExistingLibrary.doJob is not a function

External JavaScript library - ExistingLibrary.js

var ExistingLibrary = new (function () {
    this.doJob = doJob;
    function doJob(template, options) {

    function f1(template, options) {}
    function f2(template, options) {}
});

Answer 1

var ExistingLibrary = new (function () {
    this.doJob = doJob;
    function doJob(template, options) {

    function f1(template, options) {}
    function f2(template, options) {}
});

instead of this you need to export the functions like this:

export function doJob(template, options) { }
