createReactExtension()

Home > @backstage/core-plugin-api > createReactExtension

Used by createComponentExtension() and createRoutableExtension().

Signature:

function createReactExtension<T extends (props: any) => JSX.Element | null>(options: {
    component: ComponentLoader<T>;
    data?: Record<string, unknown>;
    name?: string;
}): Extension<T>;

Parameters​

ParameterTypeDescription
options{ component: ComponentLoader<T>; data?: Record<string, unknown>; name?: string; }

Returns:

Extension<T>

Remarks​

We do not use ComponentType as the return type, since it doesn't let us convey the children prop. ComponentType inserts children as an optional prop whether the inner component accepts it or not, making it impossible to make the usage of children type safe.
