Modify MS Dynamics CRM client for Nodejs plugin to retrieve all CRM 8.1 On-premise Entity Fields

We are using a node.js plugin which has limitation on querying the data in CRM where we cannot query a contact based on mobile number, we can only query based on GUID. Also, it does not have a method to retrieve all the records of the contact entity or any entity. We're looking for someone who can: 1- Take the existing plugin [login to view URL] and adjust it 2- Create a new function RetrieveAll that retrieve everything in any entity and then we query the response through JavaScript code The change is particular and we dno't want to change anything else in the plugin, it's working fine. Just to safely add this code to enable retrieving all fields under the entity. We prefer someone with experience in modifying this plugin and has used this in previous projects with CRM On-premise in particular (NOT CRM Online, we want specifically for CRM 8.1 On-premise).
