Description
It would be nice to provide a REPL for React codemods on the website, particular for ones like
createClass or PropTypes. This would be handy for one-offs like converting StackOverflow answers or fiddles and would also introduce people to the idea of codemodding in a playful way. The REPL could also include instructions for how to run the codemods on the command line.
These codemods live in reactjs/react-codemod and are published to NPM under the name react-codemod. Seems like we could add the NPM module to the website's dependencies and then embed a few of them into a new REPL component.
