Testing Mobile JavaScript

The document discusses lessons learned from examining popular jQuery plugins. It summarizes 30 top plugins, describing why each was created and how it grew. Key takeaways are that authors build plugins to make something better, for fun/exploration, or client needs. Managing features and user feedback is challenging. The best plugins have great demos, documentation, browser support testing, and are fun. The author is available for questions.

The document promotes the JHipster development tool for generating Spring Boot and AngularJS projects and provides an overview of its features such as entity generation, authentication, deployment options, and testing tools. It also demonstrates generating a blog application using JHipster and discusses how JHipster can help developers stay on top of the latest trends in Java and web development.

The document summarizes techniques for improving JavaScript performance in web applications. It discusses how JavaScript execution blocks the browser UI thread, leading to unresponsive user experiences if scripts run for too long. It then provides recommendations to limit JavaScript execution times to under 50ms and describes load time techniques like placing scripts at the bottom of the page, combining files, and loading scripts dynamically or deferring their execution to improve page load performance.

Microservices are all the rage and being deployed by many Java Hipsters. If you’re working on a large team that needs different release cycles for product components, microservices can be a blessing. If you’re working at your VW Restoration Shop and running its online store with your own software, having five services to manage and deploy can be a real pain. Share your knowledge and experience about microservices in this informative and code-heavy talk. We’ll use JHipster (a Yeoman generator) to create Angular + Spring Boot apps on separate instances with a unified front-end. I’ll also show you options for securing your API gateway and individual applications using JWT. Heroku, Kubernetes, Docker, ELK, Spring Cloud, Stormpath; there will be plenty of interesting demos to see!

This document contains information from a presentation on testing Angular applications. It discusses various testing strategies like unit testing, end-to-end testing, and continuous integration/deployment. It also covers tools like Angular CLI, TypeScript, setting up tests, mocking dependencies. Examples of unit testing Angular services and components are provided. Resources like style guides, books, and the presenter's contact details are listed at the end.

The best reason for writing tests is to automate your testing. Without tests, you'll likely be testing manually. This manual testing will take longer and longer as your codebase grows. In this session, you’ll learn how to test an Angular 2 application. You'll learn how to use Jasmine to unit test components and Protractor for integration testing. We’ll also take a look at code coverage options and explore continuous integration tools.

Overhauling one of the most visited web sites in the world is a major task, and add on top of it the pressure of keeping performance the same while adding a ton of new features, and you have quite a task. Learn how the Yahoo! homepage team achieved performance parity with the previous version even while adding a ton of new features.

This document summarizes Nicholas C. Zakas' presentation on high performance JavaScript. It discusses how the browser UI thread handles both UI updates and JavaScript execution sequentially. Long running JavaScript can cause unresponsive UIs. Techniques to ensure responsive UIs include limiting JavaScript execution time, using timers or web workers to break up processing, reducing repaints and reflows, and grouping style changes. Hardware acceleration and optimizing JavaScript engines have improved performance but responsive UIs still require discipline.

For much of its existence, JavaScript has been slow. No one complained until developers created complex web applications with thousands of lines of JavaScript code. Although newer JavaScript engines have improved the situation, there’s still a lot to understand about what makes JavaScript slow and what you can do to speed up your code.

Learn the inner workings of JavaScript to learn what makes things slow and how to speed them up. Heavily focused on DOM manipulation and UI updates.

This document discusses how timers, power consumption, and performance are related on web pages. It explains that CPUs can enter low-power sleep states when idle, but timers used in JavaScript can prevent this and increase power usage. The document recommends using higher interval timers (over 15ms) when possible to improve battery life on mobile devices. It also notes that having too many concurrent timers can flood the browser's queue and negatively impact rendering performance.

This document discusses jQuery and web performance. It describes how the jQuery Foundation maintains jQuery code and supports developers. It then discusses recent jQuery releases and how jQuery can be customized and used in different environments. The document outlines how the browser loads pages and the importance of prefetching resources. It recommends tools for analyzing page performance like YSlow, PageSpeed, and webpagetest.org. It provides tips for improving performance such as avoiding unnecessary layouts, optimizing JavaScript loops, and using developer tools to profile scripts and identify bottlenecks.

The document discusses responsive interfaces and how to keep the user interface responsive when executing JavaScript. It explains that the UI thread is used for both drawing updates and running JavaScript, so no updates can happen while JavaScript runs. It recommends keeping JavaScript execution under 50ms to avoid unresponsiveness, and describes using timers and web workers to split processing over multiple ticks to keep the UI responsive.

In this session, I show how to build a Progressive Web App (PWA) AND a mobile app using Ionic, Angular and JHipster. PWAs are being hyped as the next big thing in mobile development. This talk describes the trials and tribulations of developing the Ionic Module for JHipster. It will show how you can easily generate Ionic UIs and describe the pain points of working with Node and Yeoman to develop this module.

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!

Take some time to try various art mediums on your own, recognize your strengths, do research to learn basics, get necessary supplies, observe the world, make time for art daily, and seek feedback to develop your style.

1) The Bible does not prescribe a specific posture or location for prayer, but rather that prayer should be a sincere connection between the individual and God without attention seeking. 2) Jesus teaches that prayer should be done privately and without empty, repetitive words. He provides the Lord's Prayer as a model for elements that should be included in prayer like worship, trust in God, requests, confession, and submission to God's will. 3) The proper way to pray is with an open heart to God, being honest while keeping in mind God's will and asking for things that would honor him. God is interested in the intentions and content of our hearts rather than the exact words used.
