Progressive Web Apps (PWAs) provide an app-like user experience through the use of features like service workers, web app manifests, and push notifications. They load instantly, work offline, and can be installed on the home screen without an app store. Service workers act as a proxy to cache resources, enabling fast and reliable performance even in uncertain network conditions. PWAs are responsive across devices and browsers, and feel natural on each platform due to their immersive, app-like interfaces.

This document summarizes the author's learnings in optimizing web performance while building a progressive web app. The author implemented 5 key steps: code splitting, server-side rendering, compressing static assets, caching, and preloading assets. These optimizations led to significant increases in conversion rates and decreases in page load times, helping reduce user acquisition costs. The author hopes to further improve performance through HTML streaming in the future.

The document discusses building single page web apps and provides tips for doing so efficiently. It recommends using templating to build markup on demand, destroying and rebuilding elements, and managing data through tombstoning, on-demand loading, and purging stale data. It also recommends libraries like Backbone.js, Upshot.js, Navigation.js, and Knockout.js and discusses using local storage and deferred loading of content to improve performance of single page apps.

by @thoaud from WordCamp Nordic 2019. Introduction to The Performance First Workflow in WordPress.

This document introduces the Django web framework. It discusses what frameworks are and compares them to content management systems (CMS). It outlines some key advantages of Django like its tight integration of components and built-in admin interface. It provides an overview of Django's Model-View-Controller (MVC) architecture and shows how to set up a Django project, create a model, define URLs and views, and output data to a template.

This document discusses various front-end performance tips for ASP.NET web applications, including minimizing HTTP requests, using a content delivery network, adding expiration headers, compressing content, optimizing stylesheet and script placement, avoiding redirects, caching AJAX requests, and minifying JavaScript. It provides details on tools like FireBug and YSlow for testing front-end performance, and how to implement many of the recommendations in ASP.NET.

The document summarizes Ryan King's recent favorite WordPress plugins in 5 sentences or less each. It lists 5 plugins that meet criteria like being well designed, highly rated, and maintained. The plugins recommended are WP Nested Pages for nested pages, Ninja Forms for forms, Enable Media Replace for replacing media, BackWPup for backups, and WP Core to improve WordPress core. It also provides alternatives and tips for finding and testing plugins.

MVC, which stands for Model-View-Controller, is a popular methodology used by modern PHP frameworks to separate the presentation (HTML) from the data and logic of an application. In this talk you’ll learn how to write plugins “the MVC way” while still doing things “the WordPress way.”

This document provides tips for optimizing web apps for performance. It recommends tools like YSlow and PageSpeed Insights for analyzing page speed performance. Compressing files like JavaScript and CSS can significantly reduce file sizes. Caching static content on the server and using compression methods like Gzip and Deflate can improve performance. Minifying and obfuscating JavaScript code can further reduce file sizes. Links to additional resources on web performance are also included.

To be a successful WebVR developer, one needs skills in HTML, Three.js, A-Frame, JavaScript, and WebGL. The document provides links to learning resources for each skill, with the most resources listed for HTML, Three.js, and JavaScript. It concludes by providing contact information for the author to answer any additional questions.

In the land of web performance metrics, Speed Index is one of the most promising and robust ones around. Taking the visual progress on the user's screen into account instead of merely relying on navigation timings, it promises to give real feedback on the user experience of your website. But is it really the silver bullet? What's the catch? Can we even "cheat" on getting a better score? In this talk, we will get to the bottom of Speed Index: – We will learn how Speed Index is calculated and what you need to measure your own site's Speed Index – We will see which pain points Speed Index tackles, and what you can do to optimise your site to get a better score – We learn where the downsides of this metric are and if it should be of any concern to you – Last, but not least, we will check how we can overcome those downsides with additional, non-disruptive monitoring to get an even better view of your site's performance.

Today, a web page can be delivered to desktop computers, televisions, or handheld devices like tablets or phones. While a technique like responsive design helps ensure that our web sites look good across that spectrum of devices we may forget that we need to make sure that our web sites also perform well across that same spectrum. More and more of our users are shifting their Internet usage to these more varied platforms and connection speeds with some moving entirely to mobile Internet. In this session we’ll look at the tools that can help you understand, measure and improve the web performance of your web sites and applications. The talk will also discuss how new server-side techniques might help us optimize our front-end performance. Finally, since the best way to test is to have devices in your hand, we’ll discuss some tips for getting your hands on them cheaply. This presentation builds upon Dave’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.” This talk was given at the Responsive Web Design Summit hosted by Environments for Humans.

A 5 minute lightening talk on why progressive enhancement is the best way to be creating things for the web. This was given at 300 Seconds held at the ODI in London November 2014

This document summarizes Otto Kekäläinen's talk about investigating and recovering from a WordPress security breach at his company Seravo. On November 9th, 2018 four WordPress sites hosted by Seravo were compromised due to a vulnerability in the WP GDPR Compliance plugin. Seravo's security team launched an investigation that uncovered malicious user accounts, identified the vulnerable plugin as the entry point, and cleaned up the sites. The experience highlighted the importance of having an incident response plan even when security best practices are followed.
