myRESTApp | Architecting a Secure RESTful Node.js app | Runtime Evironment library

I'm using CodeIngiter to create a restful app.

I was wondering if is it possible to use the FormValidation class with a non $_POST data.

I was thinking: if the client send a GET request in this way:

https://myrestapp.com/controller?firstValue=val&secondValue=val2

how can I validate firstValue and secondValue using this:

I'm trying to create a website with a mobile application. I worked with web apps and REST apis separately but with this project I have to combine both.

My question is how do I have to combined this two sides of the projects.

Suposse I have a User model which has Tasks. Currently I have those models in an app called, for example, myRESTapp. But now, I want to be able to edit the tasks and take advantage of Django forms, but I'm not to do another application called webapp and implement forms based on models that are inmyRESTapi. I think it would not be a good practice considering the modularity of applications.

I build a Node.js REST implementation using this tutorial .And now i am having problems deploying it on heoroku , local works fine .

Heroku logs :

I believe the problem is with my directory structure. The "main" key of package.json and and the rest endpoints in index.js are not right

Next I was successfully able to deploy my app on Heroku but I am getting the error.My implementation is as follows :

EDIT : I removed the Procfile , compared to shown in following pics ,as I added the "start" key in package.json

Local :

Directory Structure - /webapp is the root directory :

I have package.json file at root directory and /server with different version (about which i am not sure how they should be actually for my ngClient and heroku confiurations )

Files contents of root , /webapp : package.json
