This document provides tips for boosting performance in React and Webpack applications. It discusses various optimizations that can improve build speed and bundle size for development and production environments. Some of the key recommendations include using PureComponent to minimize unnecessary re-renders, avoiding large JSX blocks, code splitting, tree shaking with Webpack 2, and leveraging tool
Gayathri Thiyagarajan Lead Software Engineer - Capgemini Andrew Harmel-Law Principal Software Engineer - Capgemini Eric Evans’ Domain Driven Design (DDD) is a core text for all developers, and it's experiencing a renaissance due to the rise of microservices. But are most of us really applying DDD when we're "doing" distributed systems development? Gayathri and Andrew are going to argue that we're

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
This document discusses moving from a traditional domain-driven design (DDD) architecture to an architecture using command query responsibility segregation (CQRS). It begins with an overview of DDD concepts like bounded contexts, the ubiquitous language, and core domains. It then discusses issues with a traditional "best practice" architecture, noting that reading and writing are different operati

This document discusses using Riot.js for building a component-based user interface. It mentions using Riot tags for article lists and individual articles. It also discusses using Gulp, concatenation, uglification, and the superagent library for AJAX requests. Modules are described for separating the View, Controller, and Model code. Examples are given of Riot tags for rendering different article

Atomic Design is a methodology for building user interfaces that advocates designing in isolation at the individual component level before assembling them into pages. The document provides examples of React component code for an announcement item, a divider, and a check toggle that demonstrate how to build reusable UI elements at an atomic level and compose them to build interfaces. It also shows
