Tasks

Handle Deprecations

Several ReactDOM methods have been deprecated in React 18

Instructions

• Replace ReactDOM.render with ReactDOM.createRoot
  • src/App.test.js
  • src/index.js

Update Client Rendering APIs

React 18 introduces a new root API which provides better ergonomics for managing roots. The new root API also enables the new concurrent renderer, which allows you to opt-into concurrent features.

Instructions

• If using render imported from react-dom, replace it with createRoot
  • src/App.test.js
  • src/index.js

Upgrade react

Instructions

• Run package commands to upgrade react
  • migrations/test/switchkeep/sample-react17-app/package-lock.json
  • migrations/test/switchkeep/sample-react17-app/package.json
