Reorganizing Website Architecture for HTTP/2 and Beyond
This document discusses reorganizing website architecture for HTTP/2 and beyond. It summarizes some issues with HTTP/2 including errors in prioritization where some browsers fail to specify resource priority properly. It also discusses the problem of TCP head-of-line blocking where pending data in TCP buffers can delay higher priority resources. The document proposes solutions to these issues such
Perl 5.28 new features

Async Redux Actions With RxJS - React Rally 2016
Redux-observable allows combining RxJS and Redux by introducing Epics. Epics are Observable streams that handle asynchronous logic in response to Redux actions. This avoids callback hell and enables features like cancellation. An Epic takes an action stream, performs asynchronous operations like AJAX calls using RxJS, and dispatches result actions. This keeps Redux synchronous while managing compl

DOM Performance (JSNext Bulgaria)
In the client-side development we manipulate the DOM very often. Some of these manipulations take some time to execute, others take even more time. In a complicated JS-based software, it is very important to find the optimal approaches in order to get best performance. We will meet few very common cases, where standard DOM manipulations are very expensive, and we will see what is the optimal way t
Towards 100% uptime with node
Eliminating every last bit of downtime caused by deployment and application errors takes some work. Learn how a combination of domains, sensible handling of uncaught exceptions, graceful connection termination, and process management with the cluster module and its friends can give you confidence that your application is always available.Read less
An introduction to React.js
This document provides an introduction to React.js, including: - React.js uses a virtual DOM for improved performance over directly manipulating the real DOM. Components are used to build up the UI and can contain state that updates the view on change. - The Flux architecture is described using React with unidirectional data flow from Actions to Stores to Views via a Dispatcher. This ensures state
