Tutorial about using Neo4js along with Node.js - node.js

Does anyone know about a tutorial or documentation on how to use neo4js in Node.js. I have successfully downloaded it but now I have no clue on how to start using it.
If there is no resources on-line that I can read, could someone point me in the right direction?
Thanks in advance!

Also,
there is an example app by Thomas Baum with a setup guide, see https://github.com/tbaum/heroku-node-neo4js

For a simplistic application you could start with this:
https://github.com/neo4j-contrib/node-neo4j-template
For a real tutorial check out this angular + node movie application:
https://github.com/kbastani/neo4j-movies-template

I know of is this screen cast - Johnny and Node.js - which shows how to get started on heroku with neo4j and node.js
There is also a neo4j challenge so you might find some examples come out of that over the next few days check twitter for #neo4jchallenge.

Is is possible to make Desktop App with Nodejs along with Online connectivity

I am trying build an application that can run offline and online too. If the application is offline it must run with minimum functionality and if it get an internet it automatically push data online Any references or tutorials would be appreciated.
any references that can help me to achieve this.
Yes, surely that's possible and you already mentioned the tools: node.js and electron are suitable. Most electron apps do that (whatsapp and joplin directly come to my mind).
You can look in the source of those already available apps, but it might be difficult. I would start with the tutorial of electron and search for the features as "check internet connectivity" (i.e. here on stackoverflow)
Your question is a bit to broadly stated to help in detail.
Yes, surely that's possible. you can use the node.js and electronJs with Angular are suitable.
For Angular and NodeJs refer the below document:
Build a Basic CRUD App with Angular and Node
For ElectronJs refer the below demo project:
Electron Samples
Best luck !!

Azure Communication Services with Ionic

I have a working project with Twilio + Ionic, but I'm wondering if you can help me with adding Azure Communication Services(video call) into my project. I tried to follow the example from the official website, but I think it's not just installing npm library and adding it as usual in my project.
If you want to see a working sample, you can use this: https://github.com/Azure-Samples/communication-services-web-calling-hero
If you're still stuck, please respond here and I'll try to help you directly.

Configuring ELK stack

I am learning to setup ELK stack.But no tutorial seems to work for me completely.
I tried to follow this guide.
Is any error here.Can any one help.Thanks in advance
I went the same path, but at the end of the day the best resource to learn is:
LOGSSTASH OFFICIAL DOCUMENTATION
and ELASTIC FORUM for logstash problems
I don't know the exact problem for above mentioned link. But i found another link and it work for me. Try ELK stack.
Could you be more specific about the OS and versions you need? Can you use Docker?
There is a nice guide for Ubuntu here
If you are using Docker, try docker-elk

Running a server MongoDB

I am trying to add a login/register system to my project (phonegap project) so I am following this guide trying to understand how to work in a server side. However I don't really get how to get the system working, nothing in the guide mentions how to setup&run the server so I am kind of stuck.
Can someone please explain to me how do I run the server with the MongoDB,Mongoose and node so that my login database would work? perhaps you can also suggest easier methods I would be glad to hear (I saw something about SQL maybe?)
Thank you :)

How Do I Set Up The MEAN (Mongo, Express, Angular & Node) stack on Nitrous.IO

I using the upcoming weekend to check two things off of my 2013 project list:
Give Cloud Development A Try
Try ANGULAR.JS
My game plan is to set up the MEAN stack on Nitrous.IO and then use the stack to complete one of the many Angularjs tutorial projects available online.
Questions:
I'd be interested in hearing if anyone has set up the MEAN stack on Nitrous or otherwise or if anyone is aware of any good blog post that go through the process for someone with little to no javascript development experience.
Also, if you have setup a MEAN stack are there any things you would do differently or are there any invaluable resources I should be aware of.
Some Resources I Found Useful:
I've been researching online for the past week and have uncovered some great resources, but it would be great to see what others have found or can suggest. Below are some links to some resources that I have come across that may be helpful to others:
Building Angular Start-up Stack - Toronto Meetup Stream
Egghead.io Offers some great Video tutorials on Angular
Google's Angular site has a wealth of info.
USC Linux User Group Youtube video on MEAN on Amazon AWS
Thanks in advance for any resources, insights or guidance.
Since you are starting on JavaScript I would suggest that you start simple. For example
Build a simple web site with Node.js and Express (no Angular, no Mongo).
Deploy it to the cloud.
Then add Angular and see how the structure changes when you use an MVC framework on the client side (e.g. your backend becomes a plain REST API).
Then, play with Node.js and Mongo probably outside your simple Node/Express/Angular app to get the hand of a NoSQL database and database access from Node.js (the fact that everything is async brings some interesting challenges for beginners)
Then integrate Mongo into your app.
Ok, here's how I successfully set-up the MEAN stack on Nitrous.IO.
First, many thanks to Valeri V. Karpov and his The Code Barbarian blog. In July he had a blog post titled Introduction to the MEAN Stack, Part One: Setting Up Your Tools. I primarily followed his article, only making adjustment dictated by the Nitrous cloud platform.
So here are the steps:
Create A Nitrous Box: Go to the Nitrous site and sign-up for an account. Please note the free account does not provide enough storage to accommodate the full MEAN Stack. You'll need at least a "Start" pricing plan - at $9.99 per month.
Create A Nodejs Box: Once you complete your registration and select a pricing plan, its time to create a Nodejs box. Follow the instructions on the Nitrous site. The box comes preconfigured Nodejs.
Install Mongodb: To install Mongodb on your box, go to the shell prompt and type: parts install mongodb You can confirm the installation was successful by typing parts start mongodb. To stop the mongodb server you type parts stop mongodb.
Confirm your Node & NPM Installations: Type node at the command prompt. You should see a > sign if node is installed correctly. You are now in the node shell. Type control-c to exit the shell. Type NPM at the prompt and you should see some usage information
Install Express: type npm install express -g The -g flag means the package will be installed so you can run it from the terminal. Note, if you are using the free box you will likely encounter errors during the Express installation as a result of you exceeded the allocated storage.
From here on you can follow Valeri's article at Step 4 Creating an ExpressJS application..
Good luck and enjoy.
Use Bitnami https://bitnami.com/stack/mean. I like it a lot, pretty simple and concise. In my case it was for Windows and it was a seamless experience
