Building Progressive Web Apps for Android and iOS

After consulting with several companies on performance related issues, it became clear that one of the biggest performance issues facing websites today is the sheer amount of JavaScript needed to power the page. The demand for more interactive and responsive applications has driven JavaScript usage through the roof. It’s quite common for large sites to end up with over 1 MB of JavaScript code on their page even after minification. But do today’s web applications really need that much JavaScript?

No one wants a slow loading, slow reacting application. As page weight has increased so has the dependency on JavaScript to drive rich user experiences. Today many pages load over 2MBs of JavaScript, but is this healthy? Do your scripts and dependencies perform well? In this session we will review common JavaScript performance bottlenecks, how to detect them and how to eliminate them. This session will review common bad coding syntax, architecture and how to replace them with better alternatives. You will also be exposed to caching, code organization, build and deployment best practices that produce the best user experiences. Finally, you will see how to use the navigation timing and performance timing APIs to fine tune your applications to produce a fast, lean application your customers will love.

In this presentation we'll take a look at building a full stack web application using Polymer and Web Components. After a quick introduction to Polymer, we’ll see how we can handle things like authentication, pagination of large data sets, and adapting our UI to different viewports. We’ll also review what’s needed for moving our app to production and optimizing our User Experience with quick load times and transition animations.

In the beginning, progressive enhancement was simple: HTML layered with CSS layered with JavaScript. That worked fine when there were two browsers, but in today's world of multiple devices and multiple browsers, it's time for a progressive enhancement reboot. At the core is the understanding that the web is not print - the same rules don't apply. As developers and consumers we've been fooled into thinking about print paradigms for too long. In this talk, you'll learn just how different the web is and how the evolution of progressive enhancement can lead to better user experiences as well as happier developers and users. This deck is a conference-agnostic one, suitable to be shown anywhere without site-specific jokes!

This document discusses using Polymer to build web component-based applications. It begins by explaining what web components are and how browsers support them through standards like custom elements, HTML imports and templates. It then introduces Polymer as a library that helps build web components and provides ready-made reusable components. The document outlines how to build full-stack apps with Polymer, including using Spring Boot on the backend to provide features like authentication. It also covers tools like Vulcanize, Crisper and build optimizations to improve performance of Polymer apps.

Over the years developers were used to thing that web is not user-friendly, performance efficient and powerful as native apps. But things have been changed so far; now you can build offline applications with notifications, Bluetooth and camera access and so on. Web development is great again. - Quick startup - I will show how to prioritize content loading in the application to show users meaningful pixels as soon as possible - Progressive enhancement - I will encourage you to use maximum of the platform but still support earlier browsers - Offline application - here I will explain how you can easily make your web application working offline - Push Notifications - one of the best way to increase conversion of your application and now it's possible on the web. I am going to show how to do it right with few steps. - Experimental APIs - I will show how to sign in once on all your devices with Credential API, use native share menu and make payments in few clicks

Polymer is the latest web framework out of Google. Designed completely around the emerging Web Components standards, it has the lofty goal of making it easy to build apps based on these low level primitives. Along with Polymer comes a new set of Elements (buttons, dialog boxes and such) based on the ideas of "Material Design". These technologies together make it easy to build responsive, componentized "Single Page" web applications that work for browsers on PCs or mobile devices. But what about the backend, and how do we make these apps secure? In this talk Scott Deeg will take you through an introduction to Polmyer and its related technologies, and then through the build out of a full blown cloud based app with a secure, ReSTful backend based on Spring ReST, Spring Cloud, and Spring Security and using Thymeleaf for backend rendering jobs. At the end he will show the principles applied in a tool he's currently building. The talk will be mainly code walk through and demo, and assumes familiarity with Java/Spring and JavaScript.

Presentation from Denver Open Source Users Group in February 2015. http://www.meetup.com/DOSUG1/events/219099019/ AngularJS is one of today's hottest JavaScript MVC Frameworks. In this session, we'll explore many concepts it brings to the world of client-side development: dependency injection, directives, filters, routing and two-way data binding. We'll also look at its recommended testing tools and build systems. Finally, you'll learn about my experience developing several real-world applications using AngularJS, HTML5 and Bootstrap.

HTML5 and its related technologies are enabling new ways to build beautiful sites and applications for contemporary mobile devices. Native mobile developers can now use web technologies to surmount cross-platform headaches, and desktop web developers can reach mobile users in familiar, app-like ways. This session explores the state of the art in HTML5-based mobile web frameworks, and demonstrates the practical possibilities that this powerful and standards-based approach can bring.

This document discusses how web design firms can compete with internal GIS teams by providing web-based GIS (WebGIS) applications. It notes that WebGIS requires learning new tools like JavaScript, AJAX, and RESTful services. To protect their work, internal GIS teams need to learn these new web technologies and prioritize usability over features to create responsive applications. The document advocates for an iterative development process with a focus on performance and usability testing.

Our application got popular and now breaks under load. The document discusses common issues that cause applications to break as user load increases, such as overuse of shared scopes, inefficient database queries, and slow client-side performance. It provides examples of better approaches and techniques to optimize performance, such as using distributed caching, improving query efficiency through joins, compressing assets, and prioritizing critical CSS and JavaScript.

Do you want to leverage HTML, CSS and JavaScripts APIs to deliver rich user experiences that outlive the framework du jour? Do You want to understand good front-end application architecture and performance principles. Then you want to build applications in Vanilla JS. Despite popular belief Vanilla JS is not as difficult to master and implement as you might think. In this tutorial Chris Love will demonstrate how to apply many common web performance optimization, good architecture and tricks to build a fast, native-like application user experience customers desire without dependency on large, fast food frameworks. This tutorial will demonstrate the following concepts: - Applying the 14kb Rule for Instant Loading - Markup Management - Eliminating Excess AJAX Calls - Working With and Around Application Cache - Applying Service Workers and HTTP/2 For Even Better User Experiences - Leveraging common browser APIs & good architecture

The document discusses the growing prevalence and performance issues of JavaScript-heavy websites. It argues that much of the client-side logic in JavaScript libraries can be moved to the server by sharing code between server and client. Several companies that have done this, like Twitter and Airbnb, are cited as seeing significant improvements to initial page load times and a better user experience. The document also advocates for a progressive enhancement approach to JavaScript, loading scripts intelligently based on user needs and minimizing unused code.

There's been a lot of talk lately about Progressive Web Apps. The main purpose is to provide an app-like user experience. For those who haven't heard of them, progressive web apps aim to bridge the gap between the mobile web and native apps by providing things like the ability to install, provide offline support, run background processes and send push notifications. What are the non-technical doubts about using it? How does it work? Is it worth to dig into PWA now?

Presented at Web Unleashed 2019 More info at www.fitc.ca/webu Andréa Crofts League Overview Examining our responsibility as creators to design for disconnection. The “restore connection” alert isn’t just for devices– it applies to people too. And it’s more important now than ever before. Digital creators, we need to talk. The rise in mental health as a result of situational stress is a prevailing theme in today’s society, and some of the products we’re building are the root cause. But we have the power to change this. As creators of digital products, how might we enable our users to be more present in their lives? How might we invest in features like Instagram’s activity timer, despite the fact that they’re fundamentally counterintuitive to the usage metrics most behemoth tech companies are driving towards? We have a responsibility as creators of digital products to enable others to disconnect …and re-connect with themselves, physically and mentally. This intersection is an emerging category Andrea likes to call digital health, and it’s something we can create together. Objective To share actionable strategies, principles and considerations for designing with digital health top of mind. Andrea will get into some #realtalk about how we can collectively create more balance and presence for the humans using our products. Target Audience Designers and digital creators of all kinds – especially those building digital products at scale! Level Open to audience members of any skill level (this is a more high-level talk) Five Things Audience Members Will Learn Tips and best-in-class examples of designing for digital health Design guidelines and principles for designing with digital health in mind Evidence-based practices to ground your future design decisions Strategies for re-framing the success metrics of digital products Design ethics resources
