Does it support React 19.2.4?
Perfect! I found the information. Looking at the peerDependencies section in the Next.js package.json file (lines 111-113), I can see:
"react": "^18.2.0 || 19.0.0-rc-de68d2f4-20241204 || ^19.0.0",
"react-dom": "^18.2.0 || 19.0.0-rc-de68d2f4-20241204 || ^19.0.0",
Yes, Next.js 16.2.0-canary.18 supports React 19.2.4 ✅
The peerDependencies configuration explicitly includes ^19.0.0, which means:
- It supports any React 19.x version (19.0.0 and above)
- React 19.2.4 falls well within that range
- It also maintains backward compatibility with React 18.2.0+ (for users not ready to upgrade)
The same applies to react-dom - the matching peerDependency also includes ^19.0.0.
