My Slides about creating web sites which could also be useable even if you are not online! From Web Storages to Service Workers. Presented at Mobiletech Conference in Munich March 2017
The web is awesome despite it's detractors. But we can't forget our fundamentals when we're trying to forge ahead with new tech. This talk is about how to approach the building blocks of the web in a way that takes advantage of their strengths and avoids their weaknesses.
At this current time, HTML5 APIs are mature enough so that the web browser can now be a very good platform for applications that were before only implemented as native applications : offline applications with locally stored data, embedded SQL engines, etc. Although there are many good Javascript frameworks out there, the Java language allows to build, maintain, debug and work with ease on really big applications (> 100,000 LOC). You'll discover in this presentation all the tools we assembled to make an application available with its data 100% of the time, even without internet!
A presentation on Ajax suitable for college level presentations and seminars.Contains 32 slides - ideal for a 20 - 30 minutes seminar.
The document discusses unobtrusive JavaScript and the UJS plugin for Rails. It describes separating JavaScript behavior from HTML content and CSS styling. The UJS plugin allows defining behaviors via CSS selectors and keeping scripts in external files. Examples are given of attaching remote behaviors to links and forms using the UJS plugin.
Ajax presents a new way of developing web applications that is more event-driven like typical client-server GUI applications. While Ajax uses technologies like JavaScript, XML, and CSS to asynchronously update parts of a page without reloading, the role of backends like Caché is reduced to basic data storage and retrieval. However, Caché remains well-suited for large, high-performance enterprise applications as they grow beyond what technologies like MySQL can easily support. Frameworks like EWD that define applications independently of technologies allow easier migration between backends like MySQL and Caché as applications scale.

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
Over the past year we have seen a lot of excitement around Progressive Web Applications. Browser evangelist are selling developers and business owners on their advantages and promising future. But what is the real story? What are the details to proper execution? What do engineers need to know to make their web sites into Progressive Web Applications that not only meet the minimum criteria, but meet the sales hype? Searching the Pokedex offline is fun, what is the real experience like caching a business application? Caching application assets and data can be complex, especially for larger applications. What to cache, how long to cache and how to cache are all valid questions. Often, in an effort to just ship something, we cache nothing. When we don't cache, we disappoint the customer and miss a key promise of progressive web applications.
On Github: http://andrewrota.github.io/complementarity-of-react-and-web-components-presentation/index.html The component driven, performance focused approach of React is a perfect complement to the modularity and portability of native HTML Web Components. At first glance, React and Web Components might seem like two radically different solutions to the same problem. But when combined properly they complement each other to create an extremely powerful, expressive framework for developing complex web applications.
This document contains slides from a presentation on Polymer and modern web APIs. The slides discuss how Polymer uses web components to build reusable custom elements, and how this allows for component-based development. They provide examples of popular elements like <paper-tabs> and <core-toolbar> that are used as building blocks. The slides also showcase several production uses of Polymer at Google scale, including the Google Santa Tracker application. They emphasize how Polymer leverages modern web platform APIs to build fast, modular, and powerful applications.
The document discusses various security vulnerabilities in Ajax applications including CSRF, login CSRF, JavaScript hijacking, XSS, and history stealing. It provides examples of how these attacks can be carried out and emphasizes the importance of validating and sanitizing user input to prevent scripts from being executed maliciously on a site. The document also recommends techniques for protecting against these attacks, such as using authentication tokens and disabling client-side script evaluation for untrusted sources.
webOS is an open source mobile operating system from Palm built on HTML5, CSS, and JavaScript that uses the Mojo framework for application development and provides services through a plugin development kit and application programming interfaces, with apps distributed through an online app catalog.
HTML5 introduces new semantic elements like <header>, <nav>, <article>, and <section> to provide more meaning and better accessibility. It also defines new form input types, 2D/3D graphics via Canvas and WebGL, offline applications, geolocation, audio, and video elements. While browser support continues to improve with HTML5 features through sites like caniuse.com, some features may not work identically or at all across browsers yet. However, HTML5 is the future of the open web and its standards will continue to be supported and built upon.
Pam Selle Co-author of Choosing a JavaScript Framework, thewebivore.com Tuesday, Oct 20th 4:20 pm - Design/UX/UI
This document provides an overview of using WordPress and AJAX. It discusses loading scripts and styles properly, using JavaScript localization to capture dynamic PHP content, page detection techniques, the wp_ajax action for handling AJAX requests, and the WP_Ajax_Response class for returning XML responses from AJAX callbacks. It also provides an example of building an AJAX registration form plugin with classes for handling the form, scripts, and styles.
Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. It allows JavaScript to be run on the server-side and is well-suited for real-time, event-driven applications due to its asynchronous and non-blocking I/O model. It was created in 2009 by Ryan Dahl who was frustrated by the limitations of JavaScript in the server-side. Node.js uses an event loop that handles asynchronous callbacks and a single thread model to achieve scalable performance. Many large companies like Uber, LinkedIn, and Netflix use Node.js for applications that require real-time features or high throughput.

Webpack is the fundamental building block of all modern Javascript application frameworks. While being flexible and powerful its plain configuration can be quite hard to understand if you just want things to "work like expected". Symfony's opinionated webpack wrapper "Encore" allows you to setup a flexible asset pipeline with 20 lines of code. This talk and its supporting git repo shows some of the concepts and ends up with a fully working Symfony 4.1 application utilizing a combined React, Vue.js and jQuery (sic) frontend. https://github.com/elmariachi111/encore-demo
Sling is a RESTful web framework for building applications on top of Apache Jackrabbit. It allows resources like content, configurations, code, and binaries to be accessed over REST URLs. Sling maps URLs to resources rather than commands, supports various scripting languages as servlets, and has a modular OSGi-based architecture powered by Apache Felix. Examples shown include building a blog and coffee ordering application on Sling to demonstrate how it supports RESTful content creation and management.
What is JavaScript? JavaScript is a very powerful client-side scripting language. JavaScript is used mainly for enhancing the interaction of a user with the webpage. In other words, you can make your webpage more lively and interactive, with the help of JavaScript. JavaScript is also being used widely in game development and Mobile application development.
This document discusses how HTML5 can be used to build engaging mobile applications. Key features covered include offline storage using the Application Cache API, storing data locally using Web Storage, using a SQL database with Web SQL, advanced graphics capabilities with Canvas and SVG, real-time communications over WebSockets, and tools for developing HTML5 apps like jQuery Mobile, Sencha Touch, and Google Web Toolkit. It emphasizes testing on multiple platforms and browsers to ensure compatibility.
This document provides an overview of HTML5 features including new HTML5 elements, offline capabilities through the App Cache, local storage options, multimedia additions like video and audio, cross-domain messaging, and the Canvas API. It discusses using these features across browsers through polyfills and shims, and emphasizes the importance of JavaScript knowledge for full HTML5 implementation. Web Sockets are introduced as enabling real-time two-way communication through a persistent connection.
Empowering the “Mobile Web” with Chris Mills “Mobile web” applications are often criticised for having inferior performance and a limited feature set, compared to “native” apps. To redress the balance, browser vendors are working on a number of technologies to grant them superpowers. In this talk, Chris Mills will discuss the inherent historic problems with mobile apps and which technologies are stepping up to fill the holes. This includes device APIs such as Web Activities, Notification, Network Information and Vibration, offline apps, installable apps and performance enhancers such as asm.js and Emscripten. Presented at FITC Toronto 2014 on April 27-29, 2014 More info at www.FITC.ca

Apache Cordova is an open-source framework that allows developers to use standard web technologies like HTML, CSS, and JavaScript to build applications that can be deployed across various mobile and desktop platforms. It works by packaging the application's code and assets into a wrapper application that loads the content into a webview. Plugins can be added to access device capabilities. The Cordova CLI provides commands for creating, building, and running Cordova projects across platforms in a consistent way. Frameworks like Angular and UI frameworks like Ionic can be used to organize larger Cordova applications.
A look at some of exciting features of HTML5, a presentation given by me at Universtiy Seminar in 7th Semester.
This document provides an overview of techniques for developing high performance web applications. It discusses why front-end performance matters, and outlines best practices for optimizing page load times, using responsive interfaces, loading and executing JavaScript efficiently, and accessing data. The presentation recommends tools for monitoring and improving performance, such as Firebug, Page Speed, and YSlow.
This document provides a summary of the state of web APIs in 2017. It begins with a brief history of web browsers and the "Browser Wars" of the 1990s. It then discusses the rise of mobile web usage, particularly in Asia and Africa, and the need for web APIs to support mobile web applications. The document proceeds to summarize several important modern web APIs, including APIs for device access, animations, games, sensors, battery status, ambient light, networking information, orientation, audio, MIDI, VR, service workers, push notifications, Bluetooth, and speech synthesis and recognition.
This document discusses mediaman's implementation of a headless architecture using Typo3 as a content management system and Magento 2 as a shop system. Some key challenges included migrating existing content, connecting different existing systems, and ensuring one user interface. The solution involved using Typo3 and Magento 2 APIs to integrate the systems while keeping the content and shop separate. Lessons learned included that being an early adopter of new technologies like Magento 2 comes with difficulties as extensions and features may not be fully developed, and going headless requires rebuilding templates and processes that rely on extensions.
The document discusses Nightwatch.js, an open source end-to-end testing framework for browser-based apps and websites. It uses Selenium WebDriver to perform commands and assertions on DOM elements. Key features include a clean syntax, built-in test runner, support for CSS/XPath selectors, test grouping/filtering, and CI integration. The document provides information on installation, project structure, configuration, writing tests, using page objects, test execution, and ways to extend Nightwatch's functionality through custom commands/assertions.
This document provides an overview of WebVR and its history. It discusses early VR devices from the 1960s, popular VR headsets today like Oculus Rift and HTC Vive, and frameworks for building VR experiences on the web like A-Frame. It also summarizes the WebVR API and how it allows accessing VR sensors and rendering to head-mounted displays from web content. While WebVR shows promise, the document notes it is still an editors draft and has limitations in browser support and requiring expensive hardware.
Slides of a talk I've given at FH Bingen about a short history of Web Development. Slides are in german.
This document provides an overview of WebVR and its history. It discusses early VR devices from the 1930s through the 1990s. Modern VR head-mounted displays like the Oculus Rift and HTC Vive are described. The WebVR API allows creating VR experiences within browsers by accessing sensors and rendering to VR displays. Frameworks like A-Frame simplify development with markup. While WebVR has potential, the specification is not finalized and high-end VR hardware can be expensive.
- HTML5 Canvas allows for drawing and animation capabilities for building games directly in browsers - It has been standardized and is supported across browsers, enabling cross-platform games - While desktop games work well with HTML5 Canvas, mobile games face challenges like lower memory limits, different screen sizes and resolutions, and performance issues - Frameworks like Phaser, Impact and libraries like CocoonJS aim to address these challenges and allow building games using HTML5 that run cross-platform on desktop and mobile browsers
Responsive design allows webpages to adapt to different screen sizes and devices by using fluid widths, images, and CSS media queries. It began in 2010 with a combination of flexible layouts, media queries, and using the viewport to optimize content for varied screens. While responsive design improves the user experience across devices, developers must address challenges like conditionally loading appropriate images, scripts, and styles to avoid delivering unnecessary content.
The document discusses the evolution of web APIs and browsers. It describes how in the early days of the web, browser vendors competed by adding proprietary features without regard to standards, which led to inconsistent support across browsers. It then explains how modern browsers now prioritize standards compliance and collaboration to ensure features work across all browsers, and how new web APIs are enabling richer mobile web experiences through access to device capabilities.
The document summarizes the history of web browsers and standards. It describes how early browsers competed by adding proprietary features without regard to standards, resulting in developer headaches. It then discusses how modern browsers have embraced standards-based development and cooperate on new technologies and APIs. The talk outlines how web APIs are helping make the web more "native" and powerful on mobile devices.

Firefox OS is a fully open source, HTML5-based mobile operating system developed by Mozilla. Apps for Firefox OS are written as regular web apps using HTML5, CSS, and JavaScript. The OS provides web APIs to access device hardware and services. App development does not require an SDK - apps are just web apps that can be hosted, privileged with permissions, or certified for distribution. The Gecko rendering engine displays HTML5-based apps and the Gaia UI provides access to the underlying OS. Developers can test apps using simulators, remote debugging tools, and UI component libraries. Apps can be distributed by hosting them online or submitting them to the Firefox OS marketplace.
This document discusses modern web UI components and frameworks. It introduces templates, custom elements, and HTML imports that allow developers to build reusable components. It then summarizes the Brick library from Mozilla, which includes common UI elements like calendars, sliders, and tabs. Developers can also build their own custom elements. The document encourages using these techniques and libraries to rapidly develop cross-browser web apps.
The document discusses Traceur, a compiler that allows developers to write JavaScript code using ECMAScript 6 features while targeting browsers that do not yet support these features natively. It provides an overview of Traceur's capabilities, how to use it through command line, Grunt, or Gulp builds, and the benefits of using a compiler like Traceur to write ES6 code now while targeting older browsers through compilation to ES5. However, it also notes that Traceur does not support all ES6 features and requires a runtime, so developers must carefully consider if their projects truly need ES6 features.
