I am currently learning React, and I am trying to build a small weatherapp to practice with apis, axios and react generally. I built an input component where it's duty is getting the data from the API, and I am holding the data in the useState hook and I want to use the data in the main App component? I am able to pass data from parent App component to input component if I take the functionality in the app component, but this time I start to have problems with input text rendering problems. Here is the code: this is the input component where I search and get the data from the API, and I am trying to pass the weatherData into the main App component and render it there. How is it possible to achieve this?
import React, { useState, useEffect } from 'react';
import axios from 'axios';
const key = process.env.REACT_APP_API_KEY;
function SearchLocation() {
const [text, textChange] = useState('');
const [weatherData, setWeatherData] = useState([]);
const handleText = (e) => {
textChange(e.target.value);
};
const fetchData = async () => {
const { data } = await axios.get(
`https://api.weatherapi.com/v1/current.json`,
{
params: {
key: key,
q: text,
lang: 'en',
},
}
);
setWeatherData(data);
};
useEffect(() => {
try {
fetchData();
} catch (error) {
console.log(error);
}
// eslint-disable-next-line react-hooks/exhaustive-deps
}, [text]);
console.log(weatherData);
return (
<div>
<form>
<input
onChange={handleText}
className="locationInput"
type="text"
value={text}
required
></input>
</form>
</div>
);
}
export default SearchLocation;
EDIT:
After moving the states to main component and passing them to children as props I receive 3 errors, GET 400 error from the API, createError.js:16 Uncaught (in promise) Error: Request failed with status code 400 and textChange is not a function error. Here are how components look like. This is the input component:
import React, { useState, useEffect } from 'react';
import axios from 'axios';
const key = process.env.REACT_APP_API_KEY;
function SearchLocation({ weatherData, setWeatherData, text, textChange }) {
const handleText = (e) => {
textChange(e.target.value);
};
const fetchData = async () => {
const { data } = await axios.get(
`https://api.weatherapi.com/v1/current.json`,
{
params: {
key: key,
q: text,
lang: 'en',
},
}
);
setWeatherData(data);
};
useEffect(() => {
try {
fetchData();
} catch (error) {
console.log(error);
}
// eslint-disable-next-line react-hooks/exhaustive-deps
}, [text]);
console.log(weatherData);
return (
<div>
<form>
<input
onChange={handleText}
className="locationInput"
type="text"
value={text}
required
></input>
</form>
</div>
);
}
export default SearchLocation;
this is the parent app component:
import React from 'react';
import { useState } from 'react';
import './App.css';
import './index.css';
import SearchLocation from './components/Input';
function App() {
const [weatherData, setWeatherData] = useState([]);
const [text, textChange] = useState('');
return (
<div className="App">
<SearchLocation
setWeatherData={setWeatherData}
lastData={weatherData}
inputText={text}
/>
</div>
);
}
export default App;
