I am pretty new to web dev, and I wanted to create a simple UI in Javascript with the Google Maps Places API to familiarize myself with everything. My question is, would I just make direct URL requests with the user’s variables, or would I have to create something server side, and if so, what would I have to do?
It depends on your application's functionality. Generally, you could keep all everything on the client-side. If you app is a server-rendered one, meaning you would be using a JavaScript framework like React or Vue, you could use just the website state to keep track of users' variables and send out requests to the Google APIs to do the heavy work.
You could also look into tools like Firebase, also created by the folks at Google to handle storage or user authentication. There are rich docs on how to include Firebase in your web application for your framework of choice. This way you can create language-agnostic backend resources that conform to all of the security measures and scales automatically so you can focus on the users' experience.
In case you would like to offer some less-common functionality or have complete control over the backend you could write up an API of your own and have it deployed on a separate backend server.

Now I program all my web apps with Flask or Django. (blogs, social networks...). I need templates, db access, controllers, routing...
Now I want to do same web applications, but with javascript.
People tell me : You need NodeJs for server-side, Angular for the front, and for example firebase or mongodb. Or also you can use Express JS.
But can I just use Angular JS and Firebase for start a big web app ? Need I Node if Angular can Access/Update/Delete in my db ?
Angular is a client-side framework, so you'll have to at least have some web server to serve your static files. Other than that, if you're using Firebase, you wouldn't technically need any server-side code to handle your logic - but naturally, that depends strongly on what data your application deals with.
If what Firebase provides, doesn't cut it for your cases though, you will need a server-side, and pretty much any web application framework would do. Node.js (using Express), PHP, ASP.NET, whatever your heart desires.
And yes, Angular works perfectly well for creating big complex web applications.

Im new to javascript and want to start writing code as clean(correct) as possible. I use C# WebApi as backend and simple pure HTML + JavaScript project for frontend.
Up until now I stored configuration for my frontend in javascript files like this:
var serviceUri = 'http://localhost:666/api/service';
And just use them somewhere.
In real applications this should be outside any javascript files, at least in my opinion. Similar to how I do it with .NET stand-alone applications or WCF services. How I should store this kind of configuration for frontend application? What is best practises?
You do not need to specify the server location of the web api in javascript. If you just use var serviceUri = '/api/service'; it will take the current server location of your page.
And if you are using static files the problem that you have to change the service location both in the js and the web api will remain and cannot be get rid of without you implementing your own compile tools (which will be a pain in the ass to find the correct routing and so on).
In the enterprise solutions I've worked on we just deal with it. You could create a js file to have all the api endpoints in one place but this could easly get ugly when there are to many.

I'm using Trigger.io to make an app I can deploy to both the app store and google play.
I'm researching baas backends that offer native sdk's for android and apple, but also offer javascript sdk's which I assume are meant for things like Trigger or Phonegap.
My question is do the app store guidelines favor one kind of back end service over another? Is javascript risky for backend? I just want to be sure before I pay for a service. The services I'm considering are cloudmine and shephertz.
They shouldn't know anything about your back-end web service.
Sounds like you are talking about making a hybird app though, which is also fine (and is technically a client). There are a ton of hybrid frameworks out there: Ionic, Cordova, Cocoon, PhoneGap, apparently Trigger.io, etc. They wouldn't be useful if app stores rejected them.

Say I have a Facebook-like website with a high volume of traffic. Now I want to implement something like a Facebook "Like" plugin(?) for my site that other websites can use on their site. Let's call it "Hooray". How do I exactly implement one?
Or how does Facebook, Pinterest, etc. generally do it?
To implement your "Hooray" button you need to have components mentioned below:
A web service which will consumed by the client SDK to report that someone has ""Hoorayed" the post etc.
You need to have a database where you can store who "hoorayed" what.
You can consider every entry as a post or say "Hurricane".
Now every post is unique so you can identify who "Hoorayed" what.
Create a web service which tells the user who "Hoorayed" what.
Create a client SDK. It could be a JS library for web applications or Objective C framework for iOS etc. These client libraries will consume web services which are mentioned above.
Just like FB you will have to ask the consumer of your "Hooray" service to register an app on your platform. You can generate an appid for them and then all the data can be tagged with that.
Obviously these are just pointers and you can create a much sophisticated workflow based on your needs.
If you go on the Facebook developers page, you can access the code for a Facebook "like" plugin in multiple languages and try to figure it out from there.

I want to create my own application for monitoring traffic of my website without using any third party tools like google analytics. In which I want to log screenshots, user details, page details and cookies. So what technology should I opt so as to achieve this goal and which will be best suited and what work flow should I follow.
I've never done this kind of work previously so I'm new to this. Any help would be greatly appreciated.
The technologies I know are : javascript, nodejs, django(python).
You will have to break down your application as it is a humongous task to create something like GA.
You will have to track many user activities(click,spend time etc).so you can do that in plain js or use a cross-platform lightweight library(angular.js) that can make your life a little easy.
Now since you will have to send large set of traced data to you database with minimum latency,use Node.js in this scenario.Simple Ajax call would also work but then it would be very slow.
Now comes your database.Prefer NoSql since it suits your requirement of unstructured data ,preferrablly MongoDb which can help you with its own mapReduce,large storage capacity
.Since there will be lot of calculation involved you can use your python knowledge which can help you process data a lot faster.you can use other languages as well(eg.Go)
Your processed data and results can then be stored in Redis(which acts as a caching layer).
you can use sophisticated graphic library like d3.js,Highcharts.js for displaying Graphical data on the client-side.
There are a lot of factors that can be involved.This is just a very basic outline of what you could do.
