Example #1
Source File: react-utils.ts    From utopia with MIT License 7 votes vote down vote up 
// Utility function to interact with react. Provides the following advantages:
  // - forces the use of a key
  // - by having key and children as separate properties, the attrs param has the correct shape for the component model
  // - it's shorter than createElement :p

  // DOM Elements
  static create<P extends HTMLAttributes<T>, T extends HTMLElement>(
    type: keyof ReactHTML,
    props?: { key: Key } & ClassAttributes<T> & P,
    ...children: ReactNode[]
  ): DetailedReactHTMLElement<P, T>
