Hello,
I have more than 30 errors while compiling the demo version. 
I can't paste them all, but how the demo version can have that much errors ?
Tried this, and works : 
yarn add @types/react@latest @types/react-dom@latest --dev
yarn add react@latest react-dom@latest
Please tell me if this is a good fix for you, and if i can continue like this.
Thanks
