kandi X-RAY | serviceworker Summary

serviceworker is a JavaScript library typically used in Server, Web Framework applications. serviceworker has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

通常使用 service worker 只需要以下几个步骤:. 首先，检测当前环境是否支持 service worker,可以使用 'serviceWorker' in navigator 进行检测。. 如果支持，可以使用 navigator.serviceWorker.register('./sw.js'),在当前主线程中注册 service worker。如果注册成功，service worker 则在 ServiceWorkerGlobalScope 环境中运行; 需要注意的是: 当前环境无法操作DOM，且和主线程之间相互独立(即线程之间不会相互阻塞)。. 安装成功之后，准备进行激活 service worker,通常在激活状态下，主要进行缓存清理，更新service worker等操作。. 激活成功后，,service worker 就可以控制当前页面了。需要注意的是，只有在service worker成功激活后，才具有控制页面的能力，一般在第一次访问页面时，service worker第一次创建成功，并没有激活，只有当刷新页面，再次访问之后，才具有控制页面的能力。.

QUESTION

How do you configure JBOSS to allow port 8080 over HTTPS?

Asked 2021-Jun-10 at 15:15

I have a JBOSS server (7.0) running an application that uses ServiceWorkers, which requires an HTTPS connection. I was able to update the standalone.xml and Eclipse launch configuration to bind my JBOSS server to my local IP (I'll worry about port forwarding later). Connecting to http://192.168.0.197:8080/[application] works just fine, except that ServiceWorkers won't start because it isn't an HTTPS connection. If I try https://192.168.0.197:8080/[application], the connection fails with the browser reporting "unable to connect".

I've researched several documentation sources and can't figure out what needs to be updated. Please forgive any terminology errors - my background is with application programming and networking tends to be the bane of my existence.

This is the pertinent standalone.xml configuration:

I'll try to break it up as much as possible, but there are plenty of things to be done.

As per the documentation, when working with Flutter Web and Firebase, you need to add your Firebase dependencies in your index.html, like this:

Use the dependencies that you want, but if you aren't using analytics, leave it out. You have to import this first thing though firebasejs/8.3.0/firebase-app.js

Can't access Azure Function Api locally from Blazor WebAssembly app

I have a Blazor WebAssembly project in Visual Studio. I have now just added an Azure Function project to the solution. I intend to publish this to the new Azure Static Web App.

I have been following the instructions in this Microsoft documentation.

Publish a Blazor WebAssembly app and .NET API with Azure Static Web Apps

ANSWER

Answered 2021-May-19 at 05:03

According to Jest:

Modules that are mapped to an alias are unmocked by default, regardless of whether automocking is enabled or not.

This means the mapped module test-utils, is trying to import a module that is not mocked, thus the import error.

If you'd wanted to create an alias for your tests like the 'test-utils' I've been trying to do, you should use moduleDirectories instead.

ModuleDirectories is an array of directory names to be searched recursively up from the requiring module's location. The default value is node_modules and in fact this is how Jest imports your third-party libraries into the tests.

Here is an example that will create an alias to a folder named 'utils':

Answered 2021-May-16 at 19:51

Consider injecting the javascript so that it runs immediately after Blazor starts on the page.

One way we may be able to accomplish this is by changing the way Blazor begins when the page is first loaded.

In wwwroot/index.html (Blazor WebAssembly) or Pages/_Host.cshtml (Blazor Server) we can modify the Blazor initializing to invoke a script after Blazor starts.

For Example (Blazor WebAssembly):

Service Worker determine number of clients

Asked 2021-May-10 at 13:14

We've got a SaaS app that's PWA capable and we're using Workbox for the grunt work. Up to now we've been following the tried and trusted recipe of displaying an update is available banner to the users, prompting them to update their web app.

Viewing usage data (via Sentry.io) we've noticed that most users simply seem to ignore the update banner and continue with the version they're on.

So we're looking at trying something different. This is to perform the update automatically when they change the route in the web app (when we know there's an update available).

Testing this shows that it does work. However there's a side-effect, and that is if they've got web app open in multiple tabs, then all the tabs get updated. This could be problematic for users' if they've got an un-saved form open in one of the tabs in the background - they'll potentially loose their work.

This happens during this piece of code:

If you want to orchestrate the reload from entirely within the service worker, you can effectively do that by using the WindowClient interface to programmatically navigate to whatever the current URL is, which is roughly equivalent to a reload.

The two things to keep in in mind that navigate() will only work on WindowClients (not Workers) and that you can only call it if the service worker controls the WindowClient.

Putting that together, here's something to try:
