After the Microsoft Store for Business and Education administrator acquires an offline app, don't publish the app to users via the store. This configuration makes sure that users can't install or update online. Users only receive offline app updates via Configuration Manager.

The Microsoft Store supports two options to license apps: online and offline. Online licensing is the default licensing model. Online licensed apps require users and devices to connect to the Microsoft Store services to acquire an app and its license. Offline licensing is a new licensing option for Windows 10. With offline licenses, organizations can cache apps and their licenses to deploy within their network. ISVs or devs can opt-in their apps for offline licensing when they submit them to the developer center. Admins control whether or not offline apps are available in Microsoft Store with an offline app visibility setting.

Open a file: You can open Office files stored on your device. To work on a file on OneDrive, OneDrive Business, SharePoint, DropBox, or Google Drive, you'll need to have opened the file in online mode at least once. You can work on it offline after you have opened it.

Save a file: You can save a file on your disk when offline. If you downloaded the file from an online location, such as SharePoint, OneDrive, or Dropbox, your latest changes will be synchronized automatically with the online version. If you make further changes while offline, you'll need to save your changes by tapping File > Save.

In our example app, we serve content from the cache instead of the network as long as the resource is actually in the cache. We do this whether the app is online or offline. If the file is not in the cache, the app adds it there first before then serving it:

Welcome to Learn Progressive Web Apps!This course covers the fundamentals of Progressive Web App development in easy-to-understand pieces. Over the following modules, you'll learn what a Progressive Web App is, how to create one or upgrade your existing web content, and how to add all the pieces for an offline, installable app. Use the menu pane to navigate the modules. (The menu is at left on desktop or behind the hamburger menu on mobile.)You'll learn PWA fundamentals like the Web App Manifest, service workers, how to design with an app in mind, what's different from a classic web app, how to use other tools to test and debug your PWA. After these fundamentals, you'll learn about integration with the platform and operating system, how to enhance your PWA's installation and usage experience, and how to offer an offline experience.Each module includes interactive demos and self-assessments for you to test your knowledge. You will be able to test and try demos on your mobile phone, tablet, or laptop while playing with code to understand the fundamentals of what makes a Progressive Web App.This course is created for a beginner and advanced web developers alike. You can go through the series from start to finish to get a general understanding of PWA from top to bottom, or you can use it as a reference for specific subjects. For those new to web development you will need a grounding in HTML, CSS, and JavaScript to follow along. Check out Learn CSS, and the HTML and JavaScript courses on MDN.Here's what you'll learn:Progressive Web AppsProgressive Web Apps (PWAs) are web apps built and enhanced with modern APIs to deliver enhanced capabilities, reliability, and installability while reaching anyone, anywhere, on any device, all with a single codebase.Getting startedIf you want to build a Progressive Web App, you may be wondering where to start, if it's possible to upgrade a website to a PWA without starting from scratch, or how to move from a platform-specific app to a PWA. This article will help you answer these questions.FoundationsAll Progressive Web Apps are, at their core, modern websites, so it's important that your website has a solid foundation in responsive design, mobile and everything first, intrinsic design, and web performance.App designOne of the key differences between Progressive Web Apps and classic websites and web apps is installability. This creates a standalone experience more integrated into the platform and operating system. Installation enables new flexibility and new responsibility, as we won't have a browser's user interface around our content.Assets and dataA Progressive Web App is a website; all its assets are the same as on the web, but with new tools to make those assets load fast when online and available when offline.Service workersService workers are a fundamental part of a PWA. They enable fast loading (regardless of the network), offline access, push notifications, and other capabilities.CachingYou can use the Cache Storage API to download, store, delete or update assets on the device. Then these assets can be served on the device without needing a network request.ServingUsing the service worker's fetch event, you can intercept network requests and serve a response using different techniques.WorkboxWorkbox is a set of modules that simplify common service worker interactions such as routing and caching. Each module addresses a specific aspect of service worker development. Workbox aims to make using service workers as easy as possible while allowing the flexibility to accommodate complex application requirements where needed.Offline dataTo build a solid offline experience you need to implement storage management. Tools like IndexedDB, Cache, Storage Manager, Persistent Storage, and Content Indexing can help.InstallationInstalled apps are easy to access and can take advantage of some deeper integrations with the OS. Learn to make your PWA installable and gain those benefits.Web app manifestThe web app manifest is a JSON file that defines how the PWA should be treated as an installed application, including the look and feel and basic behavior within the operating system.Installation promptFor sites that pass the PWA install criteria, the browser triggers an event to prompt the user to install it. The good news is that you can use this event to customize your prompt and invite users to install your app.UpdateChances are your PWA needs updating. This chapter gives you the tools to update different parts of your PWA, from assets to metadata.EnhancementsYour user expects a good experience. In this chapter, you will see how to enhance your PWA with splash screens, app shortcuts, and how sessions work.DetectionIdentifying how your users interact with your app is useful in customizing and improving the user experience. For example, you can check whether your app is already installed on the user's device and implement features such as transferring navigation to the standalone app from the browser.OS IntegrationYour PWA now works outside the browser. This chapter covers how to integrate further with the operating system once users install your app.Window managementA PWA outside of the browser manages its own window. In this chapter, you will understand the APIs and capabilities for managing a window within the operating system.Experimental featuresThere are PWA capabilities that are still under construction and you can be part of their development. In this chapter you'll learn about the Fugu project, how to sign-up for an origin trial, and how to use experimental APIsTools and debugWe will explore the tools available to develop, debug, and test your Progressive Web Apps.ArchitectureYou make some decisions when developing a PWA, such as whether to create a single page application or a multi-page application, and whether you will host it in the root of your domain or within a folder.Complexity managementKeeping a web app simple can be surprisingly complicated. In this module, you will learn how web APIs work with threading and how you can use this for common PWA patterns such as state management.CapabilitiesPWAs are not just tied to the screen. This chapter is about the capabilities that a PWA has today in terms of hardware, sensors, and platform usage.ConclusionNext steps and resources.So, are you ready to learn PWA?This course was written by Maximiliano Firtman, with input and review from Rachel Andrew, Adriana Jara, Pete LePage, Sam Richard, and Joe Medley.Next and previous lessons Next001 Progressive Web Apps Progressive Web Apps (PWAs) are web apps built and enhanced with modern APIs to deliver enhanced capabilities, reliability, and installability while reaching anyone, anywhere, on any device, all with a single codebase.

To keep the focus on the offline aspects and showing some of these new capabilities we are going to keep the scenario very simple. In this case, we are going to build an application that allows you to read twitter posts while being offline as well as tweet while being offline and when the application comes online the tweets will be posted and the local data will be reloaded.

With this release of PowerApps you can now run PowerApps and launch apps even while being offline. However, to be able to run an application you must run it at least once while being online so we can download the app.

anvil.server.AppOfflineError is raised anytime an offline app attempts to communicate with the server.In the above example, we use the try/except strategy. First, we try and save data using anvil.server.call.If we find the app is offline, the code inside the except block runs.We would then need to consider strategies for storing (caching) data in the browser inside the except block.Later, when the app comes back online, we can make the server call using the cached data. 2ff7e9595c
