While it’s lots of fun to create new applications from scratch using the latest and greatest technologies. Porting old applications to new approaches requires stepping back a bit. Updating to a modern framework means reconsidering many other connected decisions. In this project-based course, Emmanuel Henri helps you tackle the conversion process with confidence by demonstrating how to upgrade legacy apps or websites to React. To illustrate the different steps in this workflow, Emmanuel takes you through the conversion of a Vanilla JS project into a React app. He also covers the tools you’ll need to build a React app. He shows how to dissect an old webpage into components, set up the state with static data and add an external backend with Firebase, add navigation and routing, and ensure that you’re following best practices.
