Course Overview

Redux is a JavaScript library that tames your unruly data. Redux manages your app’s state. In every web app, data is critical. But while most JavaScript frameworks like Angular, Vue, and especially React are strong in presenting data, they are pretty weak in maintaining data.  

To solve this issue, the people who brought us React introduced Redux to shore up that weakness. Redux is laser-focused on taking your extremely complex data needs and simplifying them so that React (or Angular or Vue or anything else) can focus on presenting that data. It will make your UI components extremely simple and easy to change when new requirements arise in the business.

Redux Deep Dive is a comprehensive, hands-on React and Redux training course designed to teach you every aspect of Redux required to enable you to add it to any project and simplify its data needs.

Working in a hands-on learning environment, guided by our expert team, attendees will be able to:

  • Simplify complex state management with the Redux library
  • Use best practices for reducers, dispatchers, and action creators
  • Explain and leverage reducer composition
  • Understand when, how, and why to use Redux middleware
  • Handle asynchronous operations with Redux -- including Ajax
  • Integrate a Redux store into a React application

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional full stack developer, React and other related topics that may be blended with this course for a track that best suits your needs.  Our team can help design the course or learning path that best meets your needs and skills goals.
