My Worklight project contains two separate hybrid mobile applications. The applications have in common a good deal of HTML, CSS and JavaScript. I need a way to encapsulate the common code so that it can be shared by both applications.
Can Worklight Shell and Inner Applications help me to share common code across applications?
If so, where can I find detailed documentation, example code or tutorials that use Shell and Inner Applications for this purpose?
If not, is there another way to share code across Worklight applications?
Yes you can reuse, you can add to Shell common CSS, Javascript functions, Plugins and they will be applied to all the project that are build on top of that.
If it is a hybrid app you can add CSS, JS, Images under <<WLProject>>/components/<<ShellName>>/common
For any plugins related to android or IOS you can add them into respective folders under <<WLProject>>/components/<<ShellName>>
Cheers !!
Shell development in Worklight could potentially solve this for you, but its complexity is much greater and I am not convinced its price is worth it.
You can review shell development in the Advanced Topics section of the IBM Worklight Getting Started web page.

I am trying to build a desktop app.
I am thinking of using electron on the recommendation of a web-developer friend of mine, but as I am the only sole developer, I don't have the means to test the software on different platforms(OS, hardware etc.).So I am anticipating that this will cause a problem later, in the end, to test/debug software on different platforms and different OS.
I have ruled out web-apps because of some privacy concerns of the users for the remote data hosting.
Software is pretty lightweight and is almost equivalent to the image viewer apps with some slight modifications.
How to solve the problem of variations of different platforms?
Any literature suggestions pointing me in the general direction are also welcome.
Sometimes it helps to think of Electron as two processes.
The renderer vs the main processes. Generally the renderer process which runs the HTML/CSS/JS is it's own isolated component, and you communicate to the main process using IPC.
So generally for the UI, you can use mostly any web based testing framework to test reliability. At Amna, for example, we use Cypress as our E2E testing platform. You an also use something like QAWolf. Both should work with localhost. In general, most website testing tools should work fine, and consistently across platforms.
Where this gets tricky is when a UI functionality makes a call to the OS or the main process. For example, saving to the disk, or launching a program.
The general flow is this, and I've yet to find radically simpler options:
Set-Up a VM or buy a machine with the corresponding OS. I used Spot VMs in Azure for this.
Manually test the scenarios you care about in each VM before you ship
If you have a lot of cases that rely on the OS, then you should be able to further optimize this by using an automated test runner like Spectron.
From experience, what I've realized is that most of the iterations I do happen more on the UI than the underlying functions with the cross-platform capabilities. And if your code has good separation (e.g. contextIsolation:true, nodeIntegration:false), it should be pretty obvious when you need to do an entire "cross-platform" test vs just UI tests.
I'm not familiar with a lot of large-scale electron testing frameworks, I do know that ToDesktop handles package building and generating binaries to perform a smoke test and verify things open across different operating systems.
It depends.
The answer depends on what you are building, so it makes sense to figure out what you actually want to build. Some questions you might ask yourself:
Do I need a database?
Do I need authentication?
Do I need portability?
Do I need speed to market?
Do I want to pick a language I'm familiar in?
These are all good questions and there are dozens more we all ask ourselves. However, back to your original question.
Electron is a fine choice
Yes, there are alternatives. But Electron is used for Visual Studio Code, Facebook Messenger, Microsoft Teams and Figma. Choosing Electron means there are other developers making apps and there are proven apps in the market so you don't have to worry about a dead ecosystem.
Electron is easy to onboard if you know web technologies, think js, html and css. If you know these, you can transfer your web dev knowledge and make a cross-platform app. You don't have to worry about learning each OS since the UI is the webpage which will look mostly* the same between each OS. (*some very minor differences, but essentially the same).
Cross-platform deployment is easy
There are a few ways of bringing your app to multiple platforms, I happen to be most familiar with electron-builder, but the other two solutions work as well.
Many templates to start with
I am biased, since I'm the author of secure-electron-template which is one of the many templates you can choose from when starting an app. However, I recently reviewed all Electron templates and found that only 4 do not have serious security vulnerabilities.
The Electron framework frequently is updated, and over the course of the past few years there has been a shift in the way Electron apps are made. Some earlier frameworks didn't have good secure defaults which some of the older Electron templates inherited and thus, aren't as secure as new frameworks that follow security guidelines.
If you decide on Electron, give my template a try. It's got a number of features I'm building out in order to help the community with features they might want (ie. internationalization (i18n), saving local data, custom context menus, page routing, e2e unit testing, and how one can use license key validation, to name a few things).
I am working on a Hybrid Application, targeting (for the moment) iOS. Does Worklight have a utility to handle application settings/preferences for iOS? I know how to write the native code to do this, but do not yet know how to gain access to the application settings from the JavaScript. Can anyone point me in the right direction or provide a working example?
In application-descriptor.xml, there is a worklightSettings flag you can set, however the settings page it creates is not user facing. That is, it is meant only for development time, or internal usage, and not production. It allows control of the server address that athe client connects to and change the web resources it will fetch.
So the answer is, no.
The mentioned settings page has set items in it that cannot be altered much (settings.bundle which does not allow much room for play. Maybe you could change it a bit, but doing so would void giving support to you if problems arise). I would recommend against doing so.
So this leaves you the option of creating this on your own. Maybe there is an existing Cordova plug-in that does something similar. Review these training modules of how to incorporate Cordova plug-ins to your application. Cordova bridges between JavaScript to native code, so it could be what you're looking for.
In a nutshell: is RadPHP a toy? or can you build real web sites, such as a e-commerce/shopping carts app that will:
Support 100s of simultaneous users on a reasonably good web server, like any other PHP app
my specific concern is the RPCL library might be bloated and inefficient
Be easy to assign the CSS hooks and integrate CSS files supplied by designers
Be as easy as 'plain' PHP programming is to talk to external sites such as payment gateways
Easily integrate third party components; Javascript and PHP e.g. Lightbox, eg CKEditor.
I am coming from a Delphi background, not PHP, so please excuse my ignorance and trouble at evaluating RadPHP XE2's potential as an easier way to transition to web development without sacrificing potential to scale.
It has a demo app created for oscommerce the well known open source e-commerce app.
Yes
No appearent barrier.
It already has components integrating 3rd party stuff such as zend, qooxdoo, jquery etc..
I'm also coming from delphi background with almost no php. Currently I'm developing a prado framework based ERP application using eclipse as ide. On my leisure time I'm toying with radphp, and I think we could have used it as well as the eclipse-prado kit but I'm in no place to make the decision. In my experience radphp is developing well into form. The first releases / versions were really sluggish. But XE2 looks solid. If vcl for php is fine tuned for performance in the future releases, radphp will have better days.
How can I develop an installable desktop application on top of the Mozilla Engine or the Webkit engine.
We want to have best of both worlds, ease of development with DOM+Javascript+RenderingEngine+ContinuedImprovements in a Browser and user's control as in a desktop app
I looked at using C++ XPCOM for Mozilla but it seems to be quite complicated, Is there any other way to code like a WebApp using Javascript but burn it into the browser and dress it to give a feel of a desktop app. Also I require that javascript is compiled into native so that one cannot sneak into the source code
Are there any examples of desktop applications done this way ?
Web apps are fine but there are concerns of piracy, privacy, security and version control. The moot point is that in a web app the control lies with the software vendor, moreover the data is also with the vendor. Not only these, any changes to the application may also necessitate another around of training. What we want is that once the customer buys a version he is sure of what he owns and that he is in total control of it and we as software developer do not exposed our source code.
The issue is we have expertise in Web App development and we want to utilize that to develop a Desktop App
Your last point is that :

Well then BowLine can be an option though it requires Ruby, so you need to consider that. You can also take a look at WebKitDotNet if you are with .net Background.
Use XUL for the user interface and code your functions using JavaScript. You problably only need C++ to expose native functionality not yet available in Gecko. Examples of software that works this way: Komodo IDE, Songbird, Firefox and Thunderbird.
I'm trying to find a decent standalone webserver that I can load up on a jump drive.
My wife is a photographer, and I'd like to present the clients with their images on usb. When they plug it in, I'd like a web page to load up, and run some jQuery magic to show them a nice carousel of all there images.
So far, this is all fine since it can all be done client side and doesn't need a server at all.
The problem I'm facing is that I'd like some server-side code to be able to read the images out of the directory so that once the interface is built, I don't need to manually create all of the <img /> tags.
If it was primarily going to be used in a Windows environment, I'd have no problem going with IIS Express, since I'm mainly a .NET MVC developer and this would be perfect for me... However, the fact of the matter is that a large amount of our client base is also OS X users.
I did find this Java one jlHttp, and I also found this thread here on SO, but I don't think I understand enough about either one of them to accomplish what I'm looking for.
Thanks in advance for your suggestions.
I'm looking for the same thing, and the two best options I've found were Flying Ant cd web server and Stunnix. Of the two, Flying Ant is cheaper, and I've tested it with success on my project.
I found Mongoose very convenient for this exact purpose. It's crossplatform, lightweight and requires minimum configuration. You may be interested in this project that uses Mongoose to display pictures in a folder tree or FTP directory.
How about Node.js
It says it runs on Linux, OS X, and Windows.
