I want to implement a chat service on my site, and wonder how to create a simple browser-based IRC client from scratch?
I have a linux box and can install whatever I want on it. Google finds tutors on how to setup an IRC server but no instructions on how to create an IRC client.
(As client languages, I can use JavaScript or Flash.)
As you are already familiar with JavaScript, I would recommend a combination of Node.js, Now.js and node-irc.
Node.js is an application that enables you to run JavaScript server-side and to develop web-applications very fast.
Now.js is a library for Node.js that enables you to RPC between client and server. You can just call a function on the server from your client application and vice-versa; their developers guide is in fact a web chat ;)
node-irc is also a library for node.js that enables you to easily create an IRC client.
Combine these three and you get a very nice, very easy self-coded web chat. For the browser interface, there are many possibilities, including application frameworks like ExtJS, JQueryUI, KendoUI or something easier.

Is there any limitation in using a library like stanza.io for communication with an XMPP server like MongooseIM in Nativescript? What other alternatives are there?
If stanza.io supports NativeScript then there should not be any limitations.
On their GitHub main pager they say it's a Modern XMPP in the browser, with a JSON API. So it's mainly for browser env and I'm not sure about NativeScript.
As an alternative way - there is a xmpp.js lib which supports NativeScript. Their doc is a little bit shitty, but using src code there is a way to integrate successfully it.
There is a guide on how to use it for ReactNative, but you can some part from it for NativeScript, especially these part that are connected to the lib itself.
https://medium.com/#connectycube/xmpp-real-time-chat-in-react-native-8d6d5d23dd47
Also you can use some ready XMPP high level platforms for Chat, e.g. https://connectycube.com/2018/12/11/connectycube-textchat-code-sample-for-nativescript/
In this case you do not need to carte about XMPP server installation and monitoring
You will have to find a third party server or host your own one that implements XMPP protocols and connect to same using Websockets or XMPP plugin from your {N} application.
FYI, This XMPP plugin implements the same pod library explained in the MongooseIM docs, but the JavaScript apis are not fully implemented so you might have to access the native apis directly as needed.
You may also refer nativescript-xmpp-client, another exampel for XMPP implementation.
In my iphone application I am calling (by SOAP post method) a web service which is written in .net and hosted on a server, and its all working fine. But my doubt is, can we write a web service in objective c? And host it on a server? so that we should be able to access it from any of the platforms like .net, php and objectiveC.
I read a fantastic tutorial regarding this question some time ago here.
To be honest, it can be quite difficult to really use this in a productive environment. If you want to get all the features and tools Apple gives to you (what seems to be the intention of your question), you'll have to use a Mac in order to run your service afterwards.
In my opionion using PHP for example (if you need a db also backed up by MySQL) is much easier. Almost all hosters support it and you won't have to worry about setting up a bunch of macs and connecting them via solid and stable cables to the internet (and with that: guarantee availability).
Yes. A web service is just some application that can provide a service over the web. As you can create an application in Objective C, it can be a web service the same as made in any other language.
You can make it run on any server where you have an objective C compiler, however, the framework you use may restrict your choices to the server (ie, you can write objective C on windows, but you wouldn't be able to use the NS framework)
Web services are not limited to a programming language, however you do need to find if there is any framework using objective-c can run on specific server. For example, iiS allows you to use Asp.net which could be implemented using C# or VB.Net.
From the clients who will consume web services, they don't have to be a specific type of device. I think that's the point of web services. The messages travel in between is formatted. For example, a SOAP message is using xml, and that would ensure the message travel on HTTP. Therefore no matter you use iPhone or Android or Blackberry, you should have no problem to make web service calls.
So in general, I think you have to see what kind of web services you want to create, and then see if Apple(I assume) can provide you with a good framework to do it. In terms of client side, as long as your web services are using XML or JSON, it should be well supported.
Hope it helps.
I need to interface a SOAP web service and, for demonstration purposes, I also need to show the API functionality in a graphical user interface.
I would like this interface to be simple, sleek and nice looking.
What's the best technology to create this UI? I'm familiar with Java, Javascript, CSS, HTML, XML, PHP, etc..
Well, there is are a bunch of different options. You can create an application from scratch using the technologies above.
I personally recommend the playframework at http://www.playframework.org, it provides a lightweight and easy to use Web Service API.
See http://www.playframework.org/documentation/1.2.4/libs#WebServiceclient for details.
PHP is also a very good option, but I think you will get up to speed faster with Play.
Node.js is another excellent option...
Not sure how far you need to go with your UI, if it's just a matter of showing the message being sent and the answer, SOAPui may be enough, there is osx SOAP Client and REST client for mac.
Is it possible to host a GWT-compiled web application in NodeJS?
I like NodeJS however there are lots of work already made with GWT for my projects.
Cheers.
On the client side, as #riley-lark said.
You can also use GWT code on the server-side on NodeJS; see https://github.com/cretz/gwt-node and http://code.google.com/p/gwt-exporter/
Yes. GWT is a client-side technology and does not need to interact with your server at all. It is possible to send arbitrary requests to any server and process the feedback.
You won't be able to use GWT-RPC or RequestFactory.
Looking for a recommendation of which framework/web server to go with on Linux. The idea is to build database backed RESTful web services.
I know Java, c++, c# (irrelevant I guess on linux) and C. Okay with developing in any of those.
Here is a table of frameworks that have varying degrees of support for REST and the languages they use.
You might want to check out RESTx. It is multi lingual: You can write code in Java, Python (server-side JavaScript coming soon). RESTx is specifically a platform for the creation of RESTful resources and web services. It is NOT a traditional application framework. DB backed web services are actually a specialty of RESTx: You identify the reusable components you want (in this case a JDBC capable DB access component), and then just configure it through the RESTful API or by filling out a small form in a browser. As a result, you get a new RESTful web service, which encapsulates the query you specified when creating the new resource.
I'm the lead developer on RESTx, so if you have any questions, please contact me or visit our forums.
If I were you I would go with Ruby 1.9.2 + Rails 3
they're fun and you get to learn something new
