Possible Bug with routeData

If I do this

// File PersonPage.tsx

import { Show } from "solid-js";
import { RouteDataArgs, useParams, useRouteData } from "solid-start";
import { createServerData$ } from "solid-start/server";

// Components
import ComponentA from "./ComponentA";

interface IPerson {
    name: string;
    age: number;
    email: string;

    favoriteColor: string;
}

class Person implements IPerson {
    name: string;
    age: number;
    email: string;
    
    favoriteColor: string;

    constructor(person: IPerson) {
        this.name = person.name;
        this.age = person.age;
        this.email = person.email;

        this.favoriteColor = person.favoriteColor;
    }
}

function emptyPerson(): Person {
    return new Person({
        name: "",
        age: 0,
        email: "",
        favoriteColor: "",
    });
}

export function routeData({ params }: RouteDataArgs<{id:string}>) {
    return createServerData$<Person, string>(
        async(personId) => {
            const response = await fetch(`some_url/${personId}`, {
                method: 'POST',
            })

            if (!response.ok) {
                return emptyPerson();
            }
            const data = await response.json() as IPerson;

            return new Person(data)
        },
        { key: () => params.id },
    );
}

export default function PersonPage() {
    const personDetails = useRouteData<typeof routeData>();

    return (<div>
        <Show when={ personDetails()}>
            <div> Hello {personDetails().name} </div>
            <div> Age: {personDetails().age} </div>
            <div> Email: {personDetails().email} </div>

            <ComponentA />
        </Show>
    </div>);

    email: string;
    
    favoriteColor: string;

    constructor(person: IPerson) {
        this.name = person.name;
        this.age = person.age;
        this.email = person.email;

        this.favoriteColor = person.favoriteColor;
    }
}

function emptyPerson(): Person {
    return new Person({

// File ComponentA.tsx

import { Show } from "solid-js";
import { useRouteData } from "solid-start";

import { routeData } from "./PersonPage";

export default function PersonPage() {
    const personDetails = useRouteData<typeof routeData>();

    return (<div>
        <Show when= { personDetails() } >
            <div>Your favorite color: { personDetails().favoriteColor } </div>
        </Show>
    </ div>);
}

// File ComponentA.tsx

import { Show } from "solid-js";
import { useRouteData } from "solid-start";

import { routeData } from "./PersonPage";

export default function PersonPage() {
    const personDetails = useRouteData<typeof routeData>();

    return (<div>
        <Show when= { personDetails() } >
            <div>Your favorite color: { personDetails().favoriteColor } </div>
        </Show>
    </ div>);
}

I can get the data from function routeData to work in the componentA in file ComponentA.tsx Which is great! But 1) If I try to move export function routeData({ params }: RouteDataArgs<{id:string}>) into it's own file the code will break. 2) If I change the name of routeData to anything besides routeData the code will break. Neither of which make sense to me

export { routeData }

Can you elaborate? I don't really understand

21_and_da_boi•16mo ago

if you import route data from another file, it has to still be exported from the page file as routeData

Gotcha. What I was trying to do was what i saw done in the Movies example: https://github.com/solidjs/solid-start/tree/main/examples/movies

The useMovie(params: any) function that contains createRouteData is used in 3 other components files and does not seem to follow the same practice that is shown in the docs - from what I understand at least

21_and_da_boi•16mo ago

createRouteData can be used anywhere so you should be good to wrap it. routeData can't

Carlo NyteOP•16mo ago

Got it. I understand now. routeData is a reserved word that works in accordance with useRouteData. I didn't understand that from the documentation. I thought routeData was just random variable name and not something unique. I wonder if there's a way to express that better, or if I'm just an outlier and it's clear to everyone else. In any case, thank you for taking the time to explain it
