React and MobX Training Overview
React is a popular, high-performance JavaScript library for building fast, composable user interfaces. The MobX library is a variant form of the Flux pattern, providing state management for React applications using functional reactive programming.
Accelebrate’s Building Web Applications with React and MobX training class teaches experienced JavaScript developers the skills they need to immediately implement React/MobX in their applications.
Location and Pricing
Accelebrate offers instructor-led enterprise training for groups of 3 or more online or at your site. Most Accelebrate classes can be flexibly scheduled for your group, including delivery in half-day segments across a week or set of weeks. To receive a customized proposal and price quote for private corporate training on-site or online, please contact us.
In addition, some courses are available as live, instructor-led training from one of our partners.
Objectives
- Understand what React and MobX are and what problems they solve
- Explore the basic architecture of a React component
- Gain deeper knowledge of React.js components and JSX
- Utilize React Hooks
- Learn React.js best practices and common patterns
- Employ React Routing to build larger apps
- Employ the principles of MobX to build easier to understand more maintainable applications
- Correctly incorporate MobX into React component trees using React’s Context API
- Integrate Server-Side Data Sources into a React/MobX application
- Explore how to integrate the requested React Library and frameworks into a React application
Prerequisites
All React training attendees must be experienced JavaScript developers with a fairly advanced understanding of JavaScript, including prototypes and functions as first class citizens. If your group doesn’t yet have this experience, we could readily add one or two days to the beginning of your course to appropriately prepare them.
