Problem with createAsync.

When my client side try to get data from my server side with createAsync it just will always return a undefined values even when I change the getter to return a string without passing by other function or storage. It is build on the template with-auth of solidStart in typescripts. Here the function on the server side :

export const getProjects = cache(async () => {
    'use server';
    try {
        await userCheck();
        return { colDef: [], data: []};
    } catch (err) {
        throw new Error('Erreur lors de la récupération des projets');
    }
}, 'projects');

export const getProjects = cache(async () => {
    'use server';
    try {
        await userCheck();
        return { colDef: [], data: []};
    } catch (err) {
        throw new Error('Erreur lors de la récupération des projets');
    }
}, 'projects');

On the client side :

export const route = {
    load: () => getProjects(),
} satisfies RouteDefinition;

const listProject: Component = () => {
    const dataList = createAsync(() => getProjects(), {deferStream: true});
}

export const route = {
    load: () => getProjects(),
} satisfies RouteDefinition;

const listProject: Component = () => {
    const dataList = createAsync(() => getProjects(), {deferStream: true});
}

It will only run once in this case. You need to wrap in createEffect for it to run when it changes

I'm not sure to understand, why the fact that it run only once will make it so that it return undefined.

createAsync doesn't block so the data is undefined until the network request finishes

So i just need to do something like that :

const listProject: Component = () => {
const dataList = createEffect(() => createAsync(() => getProjects(),{deferStream: true})
}

const listProject: Component = () => {
const dataList = createEffect(() => createAsync(() => getProjects(),{deferStream: true})
}

Just wrap your console log in a createEffect Or render dataList in jsx

const listProject: Component = () => {
    const dataList = createAsync(() => getProjects(), {deferStream: true});
createEffect (() => console.log(dataList());
}

const listProject: Component = () => {
    const dataList = createAsync(() => getProjects(), {deferStream: true});
createEffect (() => console.log(dataList());
}

But is there a way to make it usable during the render without have to put it in a createEffect? Because I use ag-grid, so it need the data to load the grid or the only way during render is just to put everything inside a createEffect().

brenelz•6mo ago

The jsx is reactive so this should work

return <>{JSON.stringify(dataList())</>

return <>{JSON.stringify(dataList())</>

I'm using ag-grid in a project too. I use the onGridReady event and then manually set the data

It finally work with onGridReady event Thank you
