React.js Modern Web Development

Description

Components, state, effects and data fetching — building React applications that stay maintainable past the first thousand lines.

React for people building real applications rather than following tutorials. It covers component design, the state decisions that determine whether an app stays manageable, effects and their common misuse, data fetching, performance, and testing.

Who this is for

• Developers with JavaScript who need React for work
• Front-end developers moving from another framework
• Self-taught developers whose React app has become hard to change
• Full-stack developers who need the front end to be solid

What you’ll be able to do

• Design components with clear boundaries and honest prop interfaces
• Decide where state belongs — local, lifted, context or external
• Use effects correctly and recognise the cases that don't need one
• Fetch data with loading, error and empty states handled
• Diagnose and fix real performance problems rather than guessed ones
• Test components in a way that survives refactoring
