It seems this concept is so basic, there’s a lack of documentation about it. I can pass objects as props, but can’t seem to pass a basic string literal.
Functional Component
I have a functional component that takes a typed prop, like so:
const ChildComponent = (name: string) => { return ( <div className={styles.childComponent}> <p className={styles.styledName}> { name } </p> </div> ); }
and call it like so:
<ChildComponent name="testName" />
Error
VSCode throws the error on ChildComponent
:
Type ‘{ name: string; }’ is not assignable to type ‘string’
I’m very new to Typescript, but from what I can tell, it’s reading the string literal as an object.
Possible Solutions
Much of what I’ve read advises creating a custom typed prop, even for a single property, like so:
Type: NameProp { name: string }
and using that as the prop type, instead of string
.
Isn’t this overkill? Or am I missing something very basic.

Answer
const ChildComponent = ({ name }: { name: string }) => { return ( <div className={styles.childComponent}> <p className={styles.styledName}>{name}</p> </div> ); };
