I am planning to build a website and after that, to create an app with the access to the same database and the same functions as the website. So I heard, that with Ionic, I could save my time and develop a hybrid application, so I do not have to do the same work twice. The website should be a portal, which is a mix of a social network and an online shop.
What do you think, is it a good idea to use NodeJs for the Back-End for that?
So as I think my development stack would look this way:
Ionic2 with AngularJS2, NodeJS for Back-End and MySQL for storing data.
Can you say, how can I improve my development stack? Are there some things, which are bad compatible, or everything seems to be ok?
Kind regards,
Andrej
You can use web services like restful web services for accessing database from website and mobile application.

I was making a thinking exercise about how could I deploy a chat service like WhatsApp or Slack (just wondering), so people could really use it. You need two main parts, the client software (e.g. the app running on the smartphones), and the server software. So how would you develop the server-side code and make it work?
The first idea that came to me was the classic hosting service, but it cannot be the simple "web hosting service", probably because something like this should be programmed at a lower level and not working with HTTP requests and responses. Maybe using specific server-side technology like Node.js (any other suggestion?) to manage different type of requests at lower level, let's say at the layer where TCP lives, would be a better solution.
So I heard about the Amazon Web Services (AWS), which is not classic hosting, it's a cloud computing service. The problem is that I don't know exactly how this works. Could I deploy a server-side application that works at that low level of networking and also makes requests to databases? Would it be difficult to offer this kinf of service using AWS?.
I would like to hear all your opinions about any aspect of this. Would you use other kinf of technology on the server? What do you think about AWS, and if you would think it's a good option, where can I get some info to learn how to use it?
Server Side Code
You can create a chat service backend using NodeJS + express(or Hapi) to cater input Http Requests.
For Hosting: Cloud servers are pretty available these days and allow you to scale if your app grows with time.
Database:
if you already have your DB available (cool) just use ORMs ( like (Sequelize) which provides easy interaction of Nodejs service with your DB. (I have used MySQL + Sql Server + Oracle)
If not, you can create a new DB (MySql- free on your hosting server (cloud?)
I used Microsoft Azure to host a Nodejs(+ Hapi.js) Backend Service ,to be consumed by my mobile application, over the internet.
Azure gives you $200 free credit which is sufficient for you to try and make your hands dirty with them. There are numerous tutorials available for MS-Azure Api App hosting which will guide you to a successful deployment.
I have not yet explored AWS as of now, but i trust that they will be similar in their learning curves.
I'm just starting to learn more about the Node.js paradigm and finding it hard to grasp basic concepts. I'm familiar with front-end tools (HTML, CSS, JS) and have been using PHP with Apache server and mySQL db to deploy websites until now.
It seems to be that node is it's own server, and I would then need a SaaS platform like Heroku, or AWS (I'm not even sure if i'm understanding the purpose of these) if someone could explain the difference?
Is the database managed inside this service?
Is the website being hosted there?
In steps how would you get the node app to be served onto your domain name?
For Scalability purposes I understand how having dedicated big infrastructure can help, but if building a low traffic website with small number of members is there even a point in using node?
normal hosting services cost between $4-20 usd. per month and AWS or Heroku seem to start at a MUCH higher price. Is Node only to be used for large scale scaling business model?
Thank you for any answers or good recent external resources (websites or books) you could point me to.
You could easily host a low traffic website built with node.js absolutely for free on Heroku.
To see how easy that is, just go through the Getting Started With Node.js Heroku tutorial, in which you will do just that.
When you build your website with node.js, your own code that your write is the web server. You have no separate web server to configure and interact with (such as Apache). So what you see (or code...) is exactly what you get.
You will probably want to use a framework such as Express to build your web server functionality in your node.js app.
As for NoSQL databases, the way to do this on Heroku is to use an appropriate "add-on" from the Heroku Elements Marketplace. For example, you could easily add Heroku Redis or MongoLab. These are just some of the NoSQL "Database as a Service" options. That means that the Database is itself hosted somewhere in the cloud, and your app simply interacts with it. You don't need to worry about database maintenance, security upgrades etc. You just need to concentrate on your app's interaction with the DB.
Almost all add-ons in the Heroku Elements Marketplace feature a free-tier, that may suffice for your needs, at least initially. So you might be able to get your low-traffic website (including the DB) up and running completely for free, at least initially.
One thing you will need to understand is how Heroku free dyno hours work.
If you need your website to be continuously available 24/7, you may need to verify your Heroku account with a credit card (even though no charges would be incurred as long as you deploy only 1 free web dyno and are on a free-tier plan of your NoSQL DB as a Service). For further details, see this answer.
You also need to consider whether you can tolerate dyno sleeping in your low-traffic app. If not, you would need to prevent your web app from sleeping, which can also be done completely for free. For tips on how to do that see here.
As for serving your Heroku node.js app website from your own domain name, see here. Note that for this too you will need to verify your Heroku account with a credit card, although this too does not incur any charges.
Node.js is supported by many web hosting already, especially for those who use Plesk or cPanel as their web hosting control panel. Here is guide about how to setup a Node.js website via Plesk control, https://www.bisend.com/blog/how-to-set-up-a-node-js-site-in-plesk. As you said, it's very easy to host your website with a cheap shared web hosting.
I'm planning for an application that is a social media app with service like fiverr is integrated where user can communicate with each other and ask for advise.
Problem: What should be the best technology stack, weather it should be MEAN(Mongo, Express, Angular 2.x, Node) or MEN(Mongo, Express, React, Node).
Also I want it to be a REST web app, so that I can develop mobile apps later. So should I use some NodeJS framework like KeyStone or some generator like generator-meanjs. And what should be the directory structure or architecture for this.
Thanks
Choosing the best technology stack is up to the expertise of the group who would be working together. Since you are mentioning about MEAN I assume that you are well acquainted with Javascript. The answer to your other question of having the REST web app, Mean JS does provide you with the REST APIs (courtesy ExpressJS) while using CRUD module generators, You get that out of the box if you are going with mean.
Though all these utilities will help you get started from scratch in no time it really depends on the business logic of how you would want to capture the work flows. From what I get fiverr service seems to be a kind of free lancing website where one would show case their skill set and get hired. Unfortunately fiverr doesn't seem to be having an API where you can integrate your service.
Edit1: To build a service like fiverr you have to tie in various aspects not just the technology stack. There is business logic which hsa to be defined on what you'd want your app to acheive. For example let's assume you are doing some thing similar to fiverr, You would have to account for eCommerce stuff that would be happening. You would have to have user management built in to your app.(Mean.js does provide a few aspects of this, user signin/signup social media integration). Every thing else depends on what you'd actually want your service to acheive, All the best :)
Am I correct in the assumption that without access to the MongoDB server, there is not much point developing with Meteor?
Meteor is a great framework for building, packaging and deploy apps and sites. From a development POV, the templating and responsive DB work make prototyping so much easier than most MVC's.
I understand that underneath the hood, websockets and DDP provide the realtime sync'ing magic which means that you need access to the MongoDB server, something you don't have with PaaS solutions like GoogleAppEngine, Parse or Kinvey.
So, for the backend developer, they don't derive much benefit from Meteor since they need to maintain the server stack and scalability issues.
Is there a path to create and deploy products with Meteor without having to build and maintain the backend infrastructure? Heroku is still pretty close to the bone when it comes to managing infrastructure.
Wondering if there's a way to have CRUD operations through a REST driver that maps out to whatever PaaS you want and have the PaaS post log changes to a server that strictly handles websocket connections. Basically, pass the CRUD operation to a PaaS and maintain your own websocket server/s.
MeteorPedia has a page on deploying to PaaS: http://www.meteorpedia.com/read/Category:PaaS_providers
Recently, Google AppEngine has added support for custom VMs.
You can also use MongoHQ or similar for the database.
I'm trying to build a website myself but I also want to build a native mobile application that will access the same DB in the future.
What I'm thinking now is using Node.js to build Web Services wrapper for the DB and every DB operation will be executed via web service API. And for the website framework, I'm going to use Rails.
Please let me know whether this is a good architecture or not. I'm not sure whether encapsulate data with Web Services is a good idea. Will there be any performance issue? And if it's feasible, which DB should I use? And can rails communicate with DB via web services?
Thanks a lot!
Update
Why do people down vote this question??
I think you have more technology than needed in your architecture right now.
Personally I would create a REST api on top of the DB (using either node or Rails - both are super easy to do this with and both can use pretty well any db)
Then you can write any number of "apps" for the front end process, whether they are web apps, ios apps, android apps, etc... They will all get their data from your REST api on the backend.
You might even consider writing the front end as a single page app using Angular, Knockout or Backbone, something like that. If you do that with node, your entire stack will essentially be written in javascript. It can get confusing for a newb, but it's super powerful.
