https://start.solidjs.com/api/createRouteData#fetching-data-with-a-key Probably take a look at the docs again

aren't these params just the url params ? I will try anyway

Replied this in the general channel

export function routeData({ params }: RouteDataArgs<{userId:string}>) {
    return createRouteData<boolean,string>(
        async(userId) => {
        const response = await fetch(`${API_URL}/specialUser/${userId}`)
        .then(res => {
            if (res.ok) {
                return res;
            }
            return false;
        })

        if (!response) return false;

        return true;
        },
    // This is using the userId from the url to create a key for the data
    { key: () => params.userId },
    );
}


export default function SecretPage() {
    const data = useRouteData<typeof routeData>();

    return (
        <div>
            <h1>SecretPage</h1>
            {data.error && <p>{data.error}</p>}
            <Show when={data()} fallback={ <div>User is not allowed</div>}>
                <div>User can see secrets</div>
            </Show>
        </div>
    )
}

As far as I know you can't pass custom keys or signals unless they are top level/ global variables to any routeData function other that the route parameters some/path/[id] and useLocation() but I could be wrong

gmnss1917OP•17mo ago

yeah, that kinda sucks but okay, I can rearchitect around this thanks for the clarification

Carlo Nyte•17mo ago

No problem. The way I do it is to just use createResource and use the signal as my argument which will fire once the signal is updated And you can have the signal be updated in the onMount function. So it's essentially working the same just done manually plus more control
