React Typescript - Adding custom attribute

问题

React Typescript allow to add custom data-* attributes. But is it possible to add custom attributes like 'name' || 'test' act. ?

<span name="I'm causing a type error" data-test="I'm Working"/>

Bold added by me.

type error: Type '{ children: Element; name: string; data-test: string; }' is not assignable to type 'DetailedHTMLProps, HTMLSpanElement>'. Property 'name' does not exist on type 'DetailedHTMLProps, HTMLSpanElement>'. TS232

"react": "^16.7.0",
"typescript": "^3.2.4",

回答1:

in react 16+ it is possible, see

probem is that typescript didnt know about it(yet)

but you can still add @ts ignore for typechecking

{ //@ts-ignore
  <span name="I'm causing a type error" data-test="I'm Working"/>
}

回答2:

there is another way... skipping the static check (typescript don't do dynamic)

{ 
  const allowedProps = {test: "not-data-attribute"}
  <span {...allowedProps}/>
}
