React and Redux – Hands-on Workshop for Web Development
- 2 Days
React is one of the most popular and commonly used frontend frameworks. Developed and used by Facebook itself, it is a reliable and powerful tool for web application development. Whether it's a small single-page app (SPA) or a complex social network, React scales with the complexity of your application.
React has a modular structure and focuses on the essentials at its core: managing the application state and rendering components into the DOM with high performance. For almost all other problems, such as routing, you can find packages compatible with React. This way, you can create a customized solution that perfectly fits your requirements.
One of these additional packages is Redux, a state management library. It can be used as an alternative or in addition to React's state management. The architecture of Redux is simple and effective at the same time. Therefore, it is not only used in React but also in other frontend frameworks. So it's definitely worth taking a look at it.
There are also various approaches to styling with CSS. From CSS preprocessors such as LESS and SCSS, over CSS frameworks such as Bootstrap or Material Design, to design systems such as Storybook, you are spoiled for choice. We give an overview and look at the respective advantages and disadvantages.
The training is very practice-oriented. Over half of the workshop consists of applied exercises on a consistent topic. You will work through all aspects of React and Redux yourself using concrete tasks. For quality assurance, we look at both unit and integration testing using the testing frameworks Jest and Testing Library. The trainers will be at your side while you work on the tasks. After the workshop, your team will be able to apply the learned techniques directly in their daily work.
