Those statistics are crushing! But there is an explanation to that! Native mobile apps are more engaging to users than web pages. Native apps are also designed for mobile purposes, as well as in terms of graphic design, features and technical aspects. Unlike web apps, native apps have push notifications, access to your camera, or mic, but is that still true?

PWA can that too! More characteristics you can find in Lighthouse and PWA checklist section and across the whole article. Vue CLI 3. When you have your plugin installed or app created, you can find in your app tree files which are crucial in PWA app. One of the ways to make your app more engaging is making it installable.

The full list of settings you can find in official MDN web docs. PWA template app also will generate a set of icons which will be used to represent your app on mobile devices.

Service Workers: an Introduction

Few more tweaks you can make also from vue. For the full list of tweaks you can make in vue. The core feature of service workers used in PWA is its ability to intercept and handle network requests usually done by caching but thanks to the service workers you can do a lot more than only to cache your network requests. By using service workers you can also achieve background sync or push notifications.

To precache the static assets, you can put this code at the beginning of your service-worker. You can then continue programming your service worker normally in the same file, either by using the basic service worker API or by using workbox's API.

Copying to clipboard might not work on a few platforms. If copying was successful, copied to clipboard is displayed next to the local dev server URL. The vue-cli-service serve command starts a dev server based on webpack-dev-server that comes with Hot-Module-Replacement HMR working out of the box.

In addition to the command line flags, you can also configure the dev server using the devServer field in vue.

Projects created via vue create are ready to go without the need for additional configuration. The plugins are designed to work with one another so in most cases, all you need to do is pick the features you want during the interactive prompts. However, we also understand that it's impossible to cater to every possible need, and the needs of a project may also change over time.

Projects created by Vue CLI allow you to configure almost every aspect of the tooling without ever needing to eject. Check out the Config Reference for more details.

vue service worker

I used vue-cli to create a Vue app for development and so far the experience has been great. However, I also wanted to add FCM support to it which requires me adding a service worker. I have been working on the integration for two days but I still don't know how to do it and register the service worker properly. I've tried adding a new service worker firebase-messaging-sw.

Can someone show me how to do the integration, cause I really don't know how to do it. First, I think it can be both. There's a registerServiceWorker. Second, runnable reproduction is simple enough I thought I didn't need to explicitly provide any.

The replication step is simple:. Third, I'm not even asking for a solution to solve a specific problem for myself, I asked for a way to register a service worker with or without using registerServiceWorker. My purpose was to illustrate what I need was not merging multiple service workers, but I also needed to make use of the registration. As for the vue. Fourth, I found it disappointing that instead of at least pointing me to the right direction to find a solution myself, you are more fixated on whether it's a bug report or feature request because a strict policy triumphs everything.

Before I opened an issue, I already looked at all the relevant issues here:. I even asked a question on StackOverflow and included a discussion from vuejs-templates here.

I'm not asking for handouts, I just want to make the app work, and opening issue here is what I thought I had to after trying different things for two days. Yet because of a "strict" policy I got shunned down.

Thank you very much. You have it. You just misunderstood the documentation, which, I have no problem admitting, has to be refined until we leave beta. If you need more help, please use the appropriate channels, like the forum where I'm very active. We explain in detail why we ask for runnable reproductions on new-issue.

This situation is not an exception. I understand that you are a bit frustrated about being stuck, and I'm sorry for that. But in order to keep the work that we do manageabe, we have a strict process in place. You filled out the issue template, in which we explain there we have both a dedicated forum and a dedicated chat, which should be used to address questions about usage.

We are active in both. You ignored that and opened and issue without trying these sources first, because you didn't get a reply on SO within a few minutes to an hour I compared timestamps, you did both posts hours ago. A strict policy is what keeps the project manageable.

If we make an exception for everyone and everyone will have an excuse somehowwe'd be just replying to issues all day without getting any real work done. As long as an explicit registration of the service worker is required, what LinusBorg said doesn't work.

I finally sort of made it work by ditching registerServiceWorker.

When I force update the service worker From dev tool then newer version of service worker is installed and only then it fetches fresh copy of project. LinusBorg addyosmani - Any suggestions? Here's a link to video, showing service worker not being updated on page reload. It shows service worker installing, but disappears without actually installing it.

Your problem is the caching header of the server for the service worker file.

Всеволод Родионов — Paranoid Service Worker

You need to set up your web server so the caching headers are set to 0. The caching headers on the service worker script are respected up to 24 hours when fetching updates. We're going to make this opt-in behaviour, as it catches people out. You probably want a max-age of 0 on your service worker script. I can reproduce the same issue, the browser simply loads the old version that the service worker installed first time and doesn't get updated.

I tried forcing hash regeneration by commenting the corresponding lines in webpack config, but no luck sadly. I recommend that first check out server side always could serve a newer version of service worker by requests in browser because of there are many reason to counteract updates assets like cache-control. Then finally decided to go with Vue Template because didn't want to get into caching issues on production. Added console. Had to manually remove SW cache an d clean cookies.

I am with the same problem, in mobile I do not have a clear cache button in browser, someone knows how to correct? I think it's a bad idea to cache index. If you don't cache index. If there are no change to your css or js assets, you will simply use your cache. Then, for offline first experience, is better only for index.

I used jakearchibald tips, for max-age: 0 to service-worker. Default behavior of sw-precache is to load resources from cache, them update the cache in the background. Next time you refresh the page, the browser will load the updated resources from cache. Ad 1: we're using Apache httpd with a. Ad 2: if a new version is available, this leads to a reload of the page some seconds after the user loaded the page.

This works for us, but might not work for everyone else.
