typescipt and react searchbar api fetch-CodePudding

I'm trying to fetch the author's name in this search bar component. the idea is to fetch the author's name in the search bar and display the author's picture with the author's name. but it's not working for me. Can someone help and explain why this is not working. Thank you.

import { useEffect, useState } from "react";

import "./Searchbar.css";

import axios from "axios";


function Searchbar() {

    const [query, setQuery] = useState("");
    const [data, setData] = useState([]);

    useEffect(() => {
        const fetchData = async () => {
            const res = await axios.get(`https://picsum.photos/v2/?=${query}`);
            setData(res.data);
        };
        if (query.length === 0 || query.length > 2) fetchData();
    }, [query]);

    return (
        <div className="app">
            <input
                className="search"
                placeholder="Search..."
                onChange={(e) => setQuery(e.target.value.toLowerCase())}
            />
            <div>{data}</div>
        </div>
    );
}

export default Searchbar;

CodePudding user response：

Your url is wrong.

`https://picsum.photos/v2/?=${query}`

This goes to a bad page. Can you go to picsum.photos and use their available API endpoints accordingly, such as their list endpoint.

https://picsum.photos/v2/list

It looks like there's only a limited number of authors currently so you could fetch it, and store the authors array in data and then handle the searching separately.

const [query, setQuery] = useState("");
const [data, setData] = useState([]);

// Add one more state to store the authors being searched for
const [searchResults, setSearchResults] = useState([]);

useEffect(() => {
        const fetchData = async () => {
            const res = await axios.get(`https://picsum.photos/v2/list`);
            setData(res.data);
        };
        fetchData();
    }, []);

// Query that handles searching
useEffect(() => {
  setSearchResults(data.filter((authorData) => authorData['author'].toLowerCase().includes(query)));
}, [query, data]);

    return (
        <div className="app">
            <input
                className="search"
                placeholder="Search..."
                onChange={(e) => setQuery(e.target.value.toLowerCase())}
            />
            <div>{searchResults}</div>
        </div>
    );
