Install the Dependencies

The required dependencies for using Auth0 in a Cordova application are auth0.js and auth0-cordova. Install them with npm or yarn.

# installation with npm
npm install auth0-js @auth0/cordova --save

# installation with yarn
yarn add auth0-js @auth0/cordova

Add the following lines to your base code

// src/App.js

var Auth0 = require('auth0-js');
var Auth0Cordova = require('@auth0/cordova');

  return document.querySelector(arg);
