im trying to create a custom hook to search products.

import { useState } from 'react';
import {
    ITSProductQueryResponse,
    ITSTaxonomyProductQueryVars,
} from '../typesense/types/taxonomy';
import TSTaxonomy from '../typesense/taxonomy';
import { useUpdateEffect } from 'usehooks-ts';

const useFetchTsTaxonomyProducts = (queryVars: ITSTaxonomyProductQueryVars) => {
    const [data, setData] = useState<ITSProductQueryResponse>();
    const [error, setError] = useState(null);
    const [loading, setLoading] = useState(false);

    useUpdateEffect(() => {
        console.log('useFetchTsTaxonomyProducts useUpdateEffect');
        const controller = new AbortController();
        setLoading(true);
        let searchParameters = TSTaxonomy.generateSearchParams(queryVars);
        const searchOptions = {
            cacheSearchResultsForSeconds: 60,
            abortSignal: controller.signal,
        };

        TSTaxonomy.getProductDocument()
            .search(searchParameters, searchOptions)
            .then((results) => {
                setData(
                    TSTaxonomy.generateProductQueryResponse(queryVars, results)
                );
            })
            .catch(setError)
            .finally(() => setLoading(false));

        return () => {
            // controller.abort();
        };
    }, [queryVars]);

    return { data, error, loading };
};

export default useFetchTsTaxonomyProducts;

May I know what state you’re referring to? Because the search method call is stateless as it relates to query params

Jameshwart

and I need to set the loading true before the search actually happens

Ah I see…

im am doing this because we are using graphql before with useLazyQuery but not we are using your service and I am converting useLazyQuery to a custom hook. 🙂 I just don't know how useLazyQuery is done. That's why I use a library to only run an effect after first load.

typesense.js uses axios, so I wonder if axios exposes some hook

I’ve heard a few users use GraphQL with Typesense… so I’d imagine yes
