I have been developing an app using HTML, CSS, and JS, using the App Mode command line argument for Google Chrome. It works nice, but I would like some ability to use the local file system without manual input from the user. That is, if I want a file accessed directly, I want it automatically done, not requiring the user to load the file in.
One option is to disable web security, which I'm not doing because there is a need to use Google Chrome normally. I haven't been able to use a command line argument to create a separate instance of Chrome, either.
I tried working on an HTA, but any attempt to port the code to HTA ends in headaches. Also, it doesn't seem to enjoy the perks that Blink/Webkit grants.
I looked into Electron and other similar platforms, and it requires installing a handful of things, which is a no-go due to the computer setup.
Are there any solutions with a sort of portable app, that can be dropped in a folder with the HTML document (say, labeled index.html or main.html), and upon opening the browser it directly opens that file without having to configure anything? A sort of barebones chromium-based browser that only opens a single file, allowing use of HTML, JS, CSS, along with local file access? Kind of like HTA but modern?
The good news, is that it does exist, but it's not as "out-of-the-box" as HTA.
My team has migrated from HTA to WebView2.
The overall approach is to build a program with the WebView2 browser (you're basically building your own HTA like browser). Your javascript code can communicate back and forth with the program, which in turn has full access to local resources.
WebView2 is the Microsoft Edge Chromium browser, so you're getting the latest web tech and layouts (a big pain for HTA dev.). The program that contains the WebView2 control has full access to local files, scales, printers (without a pop-up dialog).
The approach has all the benefits of HTA (html / javascript programming, local file access, web based deployment, etc.), plus all layout and other benefits of a modern browser.
The program you'll build is very small, especially compared with the HUGE runtime of similar solutions, like Electron.
Rick Strahl has an excellent article on WebView2, and tips for building the program I'm describing. He has great advice on how to build an installer for it, including "Evergreen", which keeps the WebView2 up-to-date with the latest browser tech.

We have a very simple digital signage application that loads six web pages and rotates through them in an iframe.
We thought we would like to take this application and run in kiosk mode as a chromium app. However, simply using the HTML in the page has thrown all kinds of errors for the app. The most consistent on is the illegal use of external images, css, and fonts as well as complaints about javascript libraries, etc.
It looks as though it will be extremely painful to try to make this into a kiosk app.
Is it possible to make this type of conversion?
Does anyone have advice as to how to proceed?
Can you pull in external pages into a Chromium app?
You cannot run Javascript on a browser via local filesystem for security reasons. But what you could do is package the web app as a local app.
One option is to use Windows HTML Application (HTA)
http://en.wikipedia.org/wiki/HTML_Application
But this requires Internet Explorer to run.
Another option that sounds great is using Node Webkit. I have never done it before, but seems very powerful.
https://www.npmjs.com/package/nodewebkit
You can write a powerful Javascript app and run it locally this way.
UPDATE
Official Node Webkit website:
http://nwjs.io/
i am looking for an option to fully deploy the client side AJAX app written in js using qooxdoo framework.All view logic stays at Qooxdoo JavaScript framework. But i want to deploy it as desktop client too.
It already hosted on server and working fine but just to avoid Download time (JavaScript alone is 2 MB ) i also want to distribute as desktop client.
what i am looking for are :
Should work in Mac , Linux, and Windows and possibly android
Browser controls are unnecessary (location bar etc)
Should be able to run eval coz qooxdoo use eval selectively which make adobe air unable to work .
I know how to do in Xulrunner but I would prefer to do host it inside google chrome. I also finding a way to bundle xulrunner in portable way (is that already portable?can just download and run directly?)
EDIT: I looked Prism and its promising but is there anyway to bundle Client Side Web Content in a web bundle for Prism ? From its descrpition on Mozilla Wiki , we can't do that.
node-webkit looks like a viable option for packaging the entire application. I haven't used it and have only recently found out about it.
Appcelerator is an option, however there are some restrictions when using it. Some have successfully used the qx-oo (just the OO layer) with Appcelerator. Search "qooxdoo appcelerator" for more information. There may be issues when using it with the qooxdoo UI layer (which is likely the whole point of your using qooxdoo.
Lastly, one "low tech" option might be to save the web page to your local computer via your web browser and then re-distribute those saved files as the "app." I'd expect lots of problems with this, though. For example, if you're dynamically loading different components in qooxdoo these scripts might not be saved. It's easy enough to try, though.
I am thinking of building an application, kind of like TiddlyWiki in the sense that everything is self-contained in an HTML file, or at least in a bundle where a user won't have to install anything. It works on just about any browser, and on mobile phones (Android and iPhone), and in some browsers (e.g. Firefox), manages to save to the local filesystem without a plugin (albeit, it launches many security warnings, but there are other solutions for that). Other browsers happen to use a Java plugin to bypass this restriction.
Are there any technologies that exist that make this possible? HTML5's web storage sounds like it would be almost perfect, except that the data would be tied to the browser.
Any assistance would be appreciated (even if that just means editting / retagging the question to get more folks looking).
Whats about the fileapi: http://caniuse.com/#search=fileapi
I am just adding a relevant comment with this but not exactly an answer...
When you are saying that you want to develop application which contains everything... Then I would like to add about Titanium, PhoneGap, and others (Corona)...
This softwares provides JavaScript base which will be running on all the mobiles (if mobile applications), desktops (if desktop applications) and so on.... But Titanium (as i am working on it) works on the SDK of all the other languages for development...
Now TiddlyWiki, what i have understood from the link is that it is creating a web application or something like that which will work on all the other mobile devices. But this is NOT Good always, Since some application needs to be a NATIVE environment (which is supported by Titanium). Native applications will be much more faster than any other developed applications..
I am looking for Titanium Appcelerator alternatives for Desktop application development with HTML and JavaScript. I want to convert a web app to a desktop application. Hence, there will be a lot of server interaction. Appcelerator was a good choice, but it looks like the company is no longer interested in the Desktop SDK. Also, ajax request from Appcelerator does not retain cookies.
I read that Adobe Air can be used for desktop app development, but I don't want to use flash.
How good is XULRunner? Will it allow features like Growl notificaiton and creating tray icons?
Will I be able to develop applications using mostly Javascript and HTML in Qt?
I started looking into Titanium for desktop dev. I liked the concept but not the implementation. I then stumbled upon chromiumembedded and have been mostly very happy with it. It's basically a web browser control based on chromium.
http://code.google.com/p/chromiumembedded/
It's written in C++ so you can do all the low level OS stuff you want(Growl, tray icons, local file access, com ports, etc) in your container app, and then all the application logic and gui in html/javascript. It allows you to intercept any http request to either serve local resources or perform some custom action. For example, a request to http://localapp.com/SetTrayIconState?state=active could be intercepted by the container and then call the C++ function to update the tray icon.
It also allows you to create functions that can be called directly from javascript.
My biggest challenge has been debuging. It's very difficult to debug javascript directly in CEF. There's no support for anything like Firebug that I am aware of.
Appjs (appjs.org) looks very promising.
You could also check Bowline which is another alternative: http://bowlineapp.com/.
Although it's not officially intended for general-purpose use, a number of people have had success using brackets-shell for HTML/JS desktop apps. It embeds Chromium (CEF) and adds APIs for menu bar management and file IO. It also embeds an instance of Node.js so you get access to all its APIs for launching processes, etc. It's MIT-licensed and available for Mac & Win, with a Linux version currently making rapid progress.
As I mentioned, it's not officially a general-purpose app shell, but someone wrote a detailed blog post about how to customize brackets-shell for your own uses.
I notice that the other answer about Titanum says CEF is hard to debug. I'm not sure if that's true in Titanium, but in brackets-shell it's easy to debug JS – you just open http://localhost:9234/ to load a full instance of the Chrome Developer Tools (including breakpoints, profiling, etc.).
TideSDK is a continuation of the old Titanium desktop http://www.tidesdk.org/
I'm currently in the need of developing a Windows application. I want to keep things simple (in the spirit of uTorrent) and I would like the result program to be a single .exe file containing all that it needs.
The program is simple. It just needs some UI. It needs to run for a long period of time (lay there as a tray icon). It needs to do some routine tasks like simple I/O. It also needs to access the internet, specifically some web server.
Apart from these small requirements I would like to write all of it in JavaScript, as I feel more comfortable with it than any other language.
I know there's things like Windows Script Host that let you run JavaScript programs and interact with some Win32 API, but will I be able to do everything I need with Windows Script Host? Can I pack all of the Windows Script Host in a single .exe?
If not, what alternatives do I have for JavaScript?
I found that there's actually a JavaScript compiler that comes with the .NET framework called jsc.exe.
For more information:
http://www.phpied.com/make-your-javascript-a-windows-exe/
http://msdn.microsoft.com/en-us/library/7435xtz6(VS.80).aspx
I guess it's not really JavaScript since it introduces extra things like import and even some class syntax which is weird for me. But this works perfectly for me as I will just doing things as I am used to on the web.
Aside from Windows Script Host, there are
Windows Desktop Gadgets (Vista and Windows 7 only)
HTML Applications (HTAs)
Both are written with standard web technologies, HTML, JavaScript, Flash, etc. They can also be extended with COM objects/ActiveX controls such as FileSystemObject, WMI, WScript or even ones that you write yourself. Windows Desktop Gadgets have access to a separate API/namespace with various Win32-esque properties and methods.
It seems that nobody mentioned JSDB.
JSDB offers a command line environment which you can execute arbitrary javascript code. You can easily compile to a .exe file by using the command copy /b jsdb.exe+program.zip program.exe
It's important to know that you've got to call your main js file main.js within a standard zip file. Not sure if the name program.zip is required.
I haven't actually tried making GUI applications with this yet - although it seems to support various APIs like ActiveX.
It's possible that by using the copy /b command mentioned above, you could compile a script from the wscript.exe file - but I tried and couldn't get it working. Let me know if anybody tries and has success somehow.
I think you're looking for Adobe AIR
The Adobe® AIR® 2 runtime enables developers to use HTML, JavaScript, Adobe Flash® software, and ActionScript® to build web applications that run as standalone client applications without the constraints of a browser. ~ The AIR website
Internet Explorer introduced the concept of Hypertext Applications in IE 5. It never made a big breakthrough, so resources and documentation are scarce.
Mozilla-backed competitor Prism seems to be alive and well, though, and is definitely worth a look.
Prism is an application that lets users split web applications
out of their browser and run them directly on their desktop
I believe the best way to go is V8 JavaScript Engine provided by Google.
"V8 can run standalone, or can be embedded into any C++ application." - which I believe is perfect for your needs, because you can do most of the stuff in JavaScript and use provided interfaces to communicate with the system.
I'm not 100% but I believe WSH uses JScript or WScript, not JavaScript.
Color me crazy, but its only a short step form Javascript to Java or C#. I'd suggest C# as, on a windows machine, the libraries are already there. You can just copypaste your .exe and let 'er rip.
If you want a single .EXE, what runtimes are you okay if they are required pre-requisites?
If you're okay with requiring .NET runtime to be preinstalled, then you do all your work in JScript.NET
Chromium Embedded Framework (CEF) may give you some help. i have not clearly know how, but i realy found many Apps using this framework.
http://code.google.com/p/chromiumembedded/
Introduce for CEF are:
The Chromium Embedded Framework (CEF) is an open source project founded by Marshall Greenblatt in 2008 to develop a Web browser control based on the Google Chromium project. CEF currently supports a range of programming languages and operating systems and can be easily integrated into both new and existing applications. It was designed from the ground up with both performance and ease of use in mind. The base framework includes C and C++ programming interfaces exposed via native libraries that insulate the host application from Chromium and WebKit implementation details. It provides close integration between the browser control and the host application including support for custom plugins, protocols, JavaScript objects and JavaScript extensions. The host application can optionally control resource loading, navigation, context menus, printing and more, while taking advantage of the same performance and HTML5 technologies available in the Google Chrome Web browser.
Numerous individuals and organizations contribute time and resources to support CEF development, but more involvement from the community is always welcome. This includes support for both the core CEF project and external projects that integrate CEF with additional programming languages and frameworks (see the "External Projects" section below).
Why not use Rhino -- JavaScript on the JVM? You can even compile your scripts to .class files and package them into a JAR along with Rhino for easy distribution...
