app_constants | simple way to manage your application 's environment

I am migrating code of old project in to new project. In old project I am using promises for rest api requests, however, in new project I am using rxjs.

Sample of rest api request method in old project:

I am trying to make a head message (like Massenger) for firebase notifications

But my problem is the message shows up directly when the app starts without receiving any message.

I think the reason for the first problem is that I am caling the code inside oncreate, but I am not adding the view unless a message sent.

Here is the code

This is my function in NodeJs app which I am using to create user in openfire.

Hi i have this error from angular Can't resolve all parameters for RoomService: (?). i have this two files, on is the service.

I am trying to use hapi-auth-bearer-simple module to enable bearer token on my app. However, I am getting the error shown in the title.

I am trying to implement this module to enable token authorisation in my app But I am getting error mentioned below

I have a route file

I am relatively new to node.js and trying to write a route which will check the authorization of all the users if the mentioned endpoint starts with /api. I read that for optional value ? can be used {_id?} like this but is it possible to use it like {?}. and How do I call this route into another route which actually does the job of GET method?

Currently the method looks like this

This is my code now the problem here is when I am running this with hapi version 14.x.x or below it works for me perfectly fine but when I am running this with hapi version 15.0.1 or greater it gives me following error.

Is there any change in authentication process?

I am working on a project where I am making sense of what a bunch of overseas developers did in Angular JS a year before I joined the company. It's a huge project with no documentation. I was curious about if anyone has seen anything like this with so many dependencies included in the code and then each dependency renamed as a variable like (e,t,n,r,s,a), which is then included in a complex nested structure that's 140 lines long for one controller. Is this considered best practices for coding?

I have a feeling it's messier than it needs to be. Does anyone know an effective tool or methodology way to map dependencies, variables, etc. and re-organize Angular JS code?

Sample Code

I am using below code.
