Progressive Web Apps: Escaping Tabs Without Losing Our Soul It happens on the web from time to time that powerful technologies come to exist without the benefit of marketing departments or slick packaging. They linger and grow at the peripheries, becoming old-hat to a tiny group while remaining nearly invisible to everyone else. Until someone names them. This may be the inevitable consequence of a standards-based process and unsynchronized browser releases. This eventual adding-up of new technologies changes how we build and deliver experiences. URLs and links as the core organizing system: if you can’t link to it, it isn’t part of the webMarkup and styling for accessibility, both to humans and search enginesUI Richness and system capabilities provided as additions to a functional coreFree to implement without permission or payment, which in practice means standards-based Major evolutions of the web must be compatible with it culturally as well as technically. These are just the ones that spring to mind offhand. But there is now another way.
Installable Web Apps with the Web App Manifest in Chrome for Android | Web | Google Developers For Web Apps to be successful, they need to work how the user would expect a native application to work. The ability for the developer to control how their web app is launched is just one part of UX that needs to be solved. The Manifest for Web applications is a simple JSON file that gives you, the developer, the ability to control how your app appears to the user in the areas that they would expect to see apps (for example the mobile home screen), direct what the user can launch and, more importantly, how they can launch it. In the future the manifest will give you even more control over your app, but right now we are just focusing on how your app can be launched. Deploying the manifest To integrate the manifest in your own site you just need to do two things: Create and deploy a manifest file.Add a link element from the pages in your app pointing to the manifest file. Creating the manifest You can call the manifest whatever you want. An example manifest is shown below. That's it. Games
Progressive Web App Checklist | Web | Google Developers Progressive Web Apps (PWA) are reliable, fast, and engaging, although there are many things that can take a PWA from a baseline to exemplary experience. To help teams create the best possible experiences we've put together this checklist which breaks down all the things we think it takes to be a Baseline PWA, and how to take that a step further with an Exemplary PWA by providing a more meaningful offline experience, reaching interactive even faster and taking care of many more important details. Baseline Progressive Web App Checklist The Lighthouse tool is able to automatically verify many items on the this list and may prove helpful in easily testing sites. Exemplary Progressive Web App Checklist Many of these checks must be performed manually, as they are not yet implemented in Lighthouse.

Découvrir les service workers Il y a quelque temps, nous nous sommes confrontés à un nouveau besoin client : un mode d'édition offline dans une application mobile. Si plusieurs solutions s'offraient à nous, l’idée des service workers semblait prometteuse. Elle s'apparente à un proxy : dans cette configuration, le mode offline est rendu possible par un script chargé indépendamment de l’application cliente elle-même, et capable de réagir aux requêtes réseau. L'idée a été écartée en raison du rapport coût / bénéfice de ce mode développement pour le client, et d'une autre raison que vous découvrirez à la fin de ce billet. Néanmoins, nous avons poursuivi l'exploration lors de hack days, pour comprendre exactement les implications de cette nouvelle technologie. Ce billet est notre retour d'expérience sur un prototype très simple, un gestionnaire de playlist, qui fonctionne en mode offline. Le code des exemples à suivre est disponible sur Github. Nous allons maintenant créer le fichier du service worker: service-worker.js,
Lighthouse | Tools for Web Developers | Google Developers Lighthouse is an open-source, automated tool for improving the quality of web pages. You can run it against any web page, public or requiring authentication. It has audits for performance, accessibility, progressive web apps, SEO and more. You can run Lighthouse in Chrome DevTools, from the command line, or as a Node module. You give Lighthouse a URL to audit, it runs a series of audits against the page, and then it generates a report on how well the page did. You can also use Lighthouse CI to prevent regressions on your sites. Run Lighthouse In Chrome DevTools bug_report File an issue Check out the video below from Google I/O 2019 to learn more about how to use and contribute to Lighthouse.

codebusking/react-pwa-guide-kit: React.js for Progressive Web Apps that say Hello! World Introducing Pokedex.org: a progressive webapp for Pokémon fans — Pocket JavaScript To work around this, I attached a single event listener to the entire <ul>, which is responsible for animating the ripple effect on individual <li>s. Browser support As it turns out, a lot of the APIs I mention above aren't perfectly supported in all browsers. Most notably, ServiceWorker is not available in Safari, iOS, IE, or Edge. (Firefox has it in nightly and will ship very soon.) Another hurdle I ran into is that Safari does not support IndexedDB in a web worker, meaning I had to write a workaround to avoid the web worker in Safari and just use PouchDB/LocalForage over WebSQL. Surprisingly, Edge and FirefoxOS both worked without a hitch (except for ServiceWorker). Of course, I could have fixed all these compatibility issues with a million polyfills – Apple touch icons instead of Web Manifests, AppCache instead of ServiceWorker, FastClick, etc. And I'm okay with that. If we only use features that work in IE8, then we're condemning ourselves to live in an IE8 world. TODOs
Building PWAs with Vue.js Looking to get started developing Progressive Web Apps with Vue.js? Learn how to easily get PWAs built quickly using Vue. If you’ve spent any time at all online or among other web developers lately, you’ve no doubt heard the acronym PWA, or Progressive Web App, bandied about. This term, originally championed by Google, labels a class of apps purpose-built for the mobile web and which offer many of the strengths of mobile apps (offline support, home screen installation) while still maintaining the broad reach that only the web can provide. PWAs have been a topic of much discussion in the web world for the past couple of years, but have been a fringe concept for much of that time due to limited support for key technologies in both Safari and Edge. What’s a PWA? Progressive Web Apps use modern web capabilities to deliver app-like user experiences, particularly on mobile devices. Creating PWAs with Vue Before we start, if you want to follow-along at home, you’ll want to install the Vue CLI..
A Gentle and Practical Introduction to Progressive Web Apps Progressive Web Apps (PWAs) are growing in popularity and are growing in importance for web developers. Let's—gently—dive into the basics. Progressive Web Apps Progressive Web Apps (PWAs) have increasingly become an important topic for web developers. If you've ever spent any time looking into the subject, it can be… a bit overwhelming. What I hope to do in this article, and the ones that follow, is gently, and slowly, introduce you to the basics of PWAs, what they mean to me, and give you practical advice on how you can start building PWAs today. PWAs are new to me as well, so please let me know in the comments if you think I've made a mistake, or perhaps when you simply have an alternative take on the subject matter. What is a Progressive Web App, Exactly? Let's break it down. Hopefully I don't have to explain "web" - spoiler - you're on the web right now. The final part, "app", is a bone of contention for me. However - every site can benefit from the features of a PWA. The Guidelines
Choosing Mobility Options in 2018 If you are a JavaScript developer, you have never had more options for building mobile apps. You can build for the web with a Progressive Web App, build a hybrid app using Cordova, build native iOS and Android apps using frameworks like NativeScript or React Native, or choose some combination of all of these things. Here at Progress, the two biggest approaches we see as on the rise are Progressive Web Apps and JavaScript-driven native frameworks like NativeScript and React Native. TIP: If you're curious to read more about the future of JavaScript, be sure to check out our new whitepaper on the topic, The Future of JavaScript: 2018 and Beyond. We’ll start by discussing the Progressive Web App and the JavaScript-driven native approaches in detail, and move on to give some clear guidelines on when each approach makes sense.
