Simple React Snippets

The essential collection of React Snippets and commands.

snippets in action

Features

Only what you need and nothing more. No Redux. No React Native.

Simply, simple React snippets.

These snippets were selected carefully from my own day-to-day React use. Not everything in React is included here. This is a hand selected set of snippets that work the way that you would expect, not just a copy of the documentation.

Commands

React: class to className

Changes all occurences of class in JSX to className. This transform is safe to run multiple times on any document. No text needs to be selected as the command is executed on the entire document.

React: class to className

Thank You! ❤️

While I wrote the initial version of this extension, many people (too many to name) have helped make it what it is today. From providing TypeScript definitions to keeping up with changing API and best practices. If you are enjoying this extension, you have the great React community to thank.
