WePay service used to integrate WePay Elements with Angular. Forked from (https://github.com/fireflysemantics/angular-stripe-service).

import { ɵɵdefineInjectable, Injectable } from '@angular/core';

const WEPAY_API_URL = "https://cdn.wepay.com/wepay.min.js";
/**
 * This service has a `wepay` property to that gets
 * initialized to `window["WePay"]`.
 *
 * The constructor calls `inject()` which will
 * inject a script tag with containing the URL that loads
 * wepay and return a `Promise<WePayFactory>`.
 *
 * The script tag will only load wepay if
 * it is not available.
 *
 * If `window["WePay"]` is available then `inject()` resolves
 * the promise with that instance immediately, and does not create and
 * wait for the script tag to load.
