I am developing an app which would need to have files pushed to its local store for its consumption.
Is it possible to transfer files from a PC to a windows phone app local folder or say one of the Special-use folders in the local folder such as Shared/Media from a desktop application in a wired or wireless manner ? Are there any size restrictions as to the maximum data a local folder could contain for transfers done this way ?
On further research on WP8 storage i got to know about isolated storage explorer and i envision the desktop client to be similar to isolated storage explorer but customized and simplified only for the app is that possible ? meanwhile let me search more.
Yes - it does seem like it is possible. You can use the Isolated Storage Explorer in WP8.
Look at the Replacing files in the local folder in the following article on how to move files between your computer and your phone:
How to use the Isolated Storage Explorer tool for Windows Phone
Eventually i ended up using socket programming to solve this, Stephen Cleary's blog post here helped a lot to brush up the basics

I am developing an invoice app with Angular + NodeJs + MySql.
The thing is, the app is planned to be used by one employee in his office. No need for online servers.
It is not problematic to deploy the app online, but the internet is unstable in the zone (Latinamerican problem. You may lose connection for hours, and even voltage variations that may shut down the PC).
So the app must be self sufficient to always work offline.
So my questions are:
Can I simply deploy the app offline? Like in local. If that is the case, I would need for everything to be initialized automatically when the user opens the app (server open, database connected...).
If I have no way but to deploy the app online, should I use Firebase? Also, what happen if the internet service shut downs for hours? Is there a way for the database to be available offline and sync when the internet gets back?
You could build the app as an Electron App, then its becomes a locally run program. https://www.electronjs.org/
You can host it anywhere, but turn the app in to a PWA, which means it will work locally in the browser after a successful visit (gets installed with a service worker in browser) For the database it self, you can store data in the browser but some are limited to 5mb of data in the localstorage / sessionStorage / indexdb. Firebase does have some locally cached data. But if the browser is closed it can be lost.
If it needs to run locally i would go the electron route. Its slightly harder to do but it fills out your usecase better.
You can use both ways if you want to be sync like situation you have to hold data if your internet is not working in local storage or indexed db.
and it is fine you can deploy locally also or make one dedicated server which is always on.so any body in same network can use that angular app easily.
Just take care of backup plan when you system corrupt you should have proper backup of database for such scenario.
I have accidentally killed one of my WP projects in VS2013. I receovered the source code from the backup, but now, if I try to recompile it and deploy to my device for further debugging, all my app data in the app IsolatedStodage area will be wiped (see this post).
The problem is that I have gathered some important data in my app, and need to save them for later use with newer versions of my app. Is there a way to access the file system on a WP device unlocked for development and save the corresponding IsolatedStorage files for the app? I know that it's possible for the WP8/8.1 emulator (we can mount the .vhd files), but what about a WP device? And if it it's possible, what files/folders do we need to save?
Try IsoStoreSpy.
It allows you to browse the IsolatedStorage of application on both emulator and device. You need to copy all the files from IsolatedStorage and upload them to device after updating the application.
I'm building a packaged app that's meant to interact with a website I wrote to get its localStorage data and send it to other devices using bluetooth. This seems like it would be easy with an extension, however with an extension I would not have access to chrome's bluetooth API. I'm not sure this is even possible, but if it is, how would I go about accessing and communicating with the website using the packaged app?
The answer is that you can't. The two local storage repositories are distinct ("sandboxed"), and one can't access the other.
If this website wants to make data available to any other website, or to a Chrome App, it should put it someplace on the server, accessible via a URL, and then the Chrome App can easily access it. But, there's no way to effect such sharing with the data on the client.
Two Chrome Apps can share data locally, because they can access the local file system. However, web apps (HTML/JavaScript loaded from a server) can't access the local file system, only a sandboxed file system.
If I write a web app that will run in Chrome or Firefox and uses IndexedDB (or localStorage), but it's not hosted anywhere and instead is run by the user double-clicking a local ".html" file, will the limits on storage size still apply?
I'm referring to this:
https://developers.google.com/chrome/whitepapers/storage#unlimited
[Unlimited Storage is] unique to Chrome extensions as well as hosted and installed web apps.
If it is not hosted, indexeddb won't work. The indexeddb is origin dependend, meaning it needs to have an address. Local file system doesn't meet that requirement.
Webapps are a different story, but these apps need to be installed and run inside a sandbox.
I'm writing a Google Chrome app that stores things locally with the HTML5 FileSystem API. Is there any way to use Windows Explorer to get to the directory where Chrome stores these files or is it entirely virtual and inaccessible from outside the app? I haven't been able to find the directory by poking around nor have I seen any reference online to it.
I suppose I could just write something within the app to allow me GUI management of the files my app stores or just use the developer console, but it would really be a time saver to use WE.
Nevermind, I just found it. For anyone looking, it's in (on my windows 7 machine at least)
C:\Users\ user \AppData\Local\Google\Chrome\User Data\Default\File System
Also note that this was in Chrome 11, in Chrome 13 there were some changes to the FileSystem (probably for security) that make it very difficult to find specific files by scrolling through the files in Chrome's AppData space.
