I'm currently making a simple web frontend with react using react-autosuggest to search a specified user from a list. I want to try and use the Autosuggest to give suggestion when the user's type in the query in the search field; the suggestion will be based on username of github profiles taken from github user API.
What I want to do is to separate the AutoSuggest.jsx and then import it into Main.jsx then render the Main.jsx in App.js, however it keeps giving me 'TypeError: _ref2 is undefined' and always refer to my onChange function of AutoSuggest.jsx as the problem.
Below is my App.js code:
import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';
import Header from './views/header/Header';
import Main from './views/main/Main';
import Footer from './views/footer/Footer';
const App = () => {
return (
<>
<Header/>
<Main/> <- the autosuggest is imported in here
<Footer/>
</>
);
}
export default App;
Below is my Main.jsx code:
import React, { useState } from 'react';
import Container from 'react-bootstrap/Container';
import Row from 'react-bootstrap/Row';
import axios from 'axios';
import { useEffect } from 'react';
import AutoSuggest from '../../components/AutoSuggest';
const Main = () => {
const [userList, setUserList] = useState([]);
useEffect(() => {
axios.get('https://api.github.com/users?per_page=100')
.then((res) => setUserList(res.data))
.catch((err) => console.log(err));
}, [])
return (
<Container>
<br/>
<Row>
<AutoSuggest userList={userList} placeHolderText={'wow'} />
</Row>
</Container>
);
}
export default Main;
Below is my AutoSuggest.jsx code:
import React, { useState } from "react";
import Autosuggest from 'react-autosuggest';
function escapeRegexCharacters(str) {
return str.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');
}
function getSuggestions(value, userList) {
const escapedValue = escapeRegexCharacters(value.trim());
if (escapedValue === '') {
return [];
}
const regex = new RegExp('^' + escapedValue, 'i');
return userList.filter(user => regex.test(user.login));
}
function getSuggestionValue(suggestion) {
return suggestion.name;
}
function renderSuggestion(suggestion) {
return (
<span>{suggestion.name}</span>
);
}
const AutoSuggest = ({userList, placeHolderText}) => {
const [value, setValue] = useState('');
const [suggestions, setSuggestions] = useState([]);
const onChange = (event, { newValue, method }) => { <- error from console always refer here, I'm not quite sure how to handle it..
setValue(newValue);
};
const onSuggestionsFetchRequested = ({ value }) => {
setValue(getSuggestions(value, userList))
};
const onSuggestionsClearRequested = () => {
setSuggestions([]);
};
const inputProps = {
placeholder: placeHolderText,
value,
onChange: () => onChange()
};
return (
<Autosuggest
suggestions={suggestions}
onSuggestionsFetchRequested={() => onSuggestionsFetchRequested()}
onSuggestionsClearRequested={() => onSuggestionsClearRequested()}
getSuggestionValue={() => getSuggestionValue()}
renderSuggestion={() => renderSuggestion()}
inputProps={inputProps} />
);
}
export default AutoSuggest;
The error on browser (Firefox) console:
I have no idea what does the error mean or how it happened and therefore unable to do any workaround.. I also want to ask if what I do here is already considered a good practice or not and maybe some inputs on what I can improve as well to make my code cleaner and web faster. Any input is highly appreciated, thank you in advance!
