The ideia here will be

Create TokenHelper.js and SharePointContext.js

Based in these files base/TokenHelper.cs and base/SharePointContext.cs

Setup

1. Go to /_layouts/15/AppRegNew.aspx and register a new application

2. Create a SharePoint App Provider hosted and delete the MVC project

3. Open AppManifest.xml

<RemoteWebApplication ClientId="{{app_client_id}}" />
<RemoteEndpoints>
  <RemoteEndpoint Url="https://localhost:3030" />
</RemoteEndpoints>

1. Create File config.js and them put the client_id and appSecret

module.exports = {
    client_ID:"{{clientID}}",
    appSecret:'{{appSecret}}'
}
