const api_call = await fetch(`.5/weather?q=${city}&appid=${API_KEY}&units=metric`);
const data = await api_call.json();
console.log(data)
if (city) {
this.setState({

Reset to default 4In order for you to display the icon, you need to use the URL and not just icon value. Something like this
The value returned from the API is '09d'. So you will have to append the URL with string url to have the weather api url appended with image and image extension.
{http://openweathermap/img/w/${props.icon}.png
}
Few other things noticed in your code is ,
You are setting default values as undefined, which is not correct.
Please use proper value, something like
state = { temperature: '', city: '' }
https://codesandbox.io/s/6102m4kn3r
as per your code in weather.js
<img src ={`http://openweathermap/img/w/${this.props.icon}.png`} alt="wthr img" />
it will display the weather icon...ie
import React, { Component } from 'react';
class Weather extends Component {
render() {
return (
<div>
<p>WeatherNow:
<img src ={`http://openweathermap/img/w/${this.props.icon}.png`}
alt="wthr img" />
</p>
</div>
);
}
}
export default Weather;
You have to make change in src attribute of <img>
.
As given in Weathermap api you have to request icon by http://openweathermap/img/w/10d.png.
Replace 10d.png
by props.icon+'.png'
. It will work.
In order for you to display the icon, you need to use the URL. Something like the below code
<img src={`http://openweathermap/img/w/${data.weather[0].icon}.png`} height="70px" />
