React Typescript - Adding custom attribute

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",
Solution

  • 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"/>
}
