I am creating a weather app with react native for fun. I am using an api to get the weather information which is stored as json.
I would like to be able to display the hourly weather based on what time of the day it is.
export default class App extends React.Component {
constructor (props) {
super(props);
this.state = {
isLoading: true,
};
}
componentDidMount() {
const fetch = require('node-fetch');
fetch('https://api.weatherapi.com/v1/forecast.json', {
method: 'GET',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
}).then((response) => response.json())
.then((responseJson) => {
console.log(responseJson);
this.setState({
isLoading: false,
dataSource: responseJson,
})
console.log(responseJson.forecast.forecastday[0].hour[0].time.split(" ")[1]);
const time = responseJson.location.localtime.split(" ")[1];
}).catch((error) => {
console.error(error);
});
}
render() {
if (this.state.isLoading) {
return (
<View style=>
<ActivityIndicator />
</View>
);
}
return (
<View style=>
<Text style={styles.text}>{this.state.dataSource.location.name}</Text>
<Text style={styles.mainText}>{this.state.dataSource.current.condition.text}</Text>
<Text style={styles.tempText}>{this.state.dataSource.current.temp_c + '℃'}</Text>
<View style=>
<Text style={styles.maxTempText}>{'H: ' + this.state.dataSource.forecast.forecastday[0].day.maxtemp_c + '℃'}</Text>
<Text style={styles.maxTempText}>{'L: ' + this.state.dataSource.forecast.forecastday[0].day.mintemp_c + '℃'}</Text>
</View>
</View>
);
}
}
const myMainTime = () => {
const mainTime = this.state.dataSource.forecast.forecastday[0].hour[0].time.split(" ")[1];
{this.state.dataSource.forecast.forecastday[0].hour.map((item) => (
if ( mainTime >= time ) {
return (
<ScrollView horizontal={true}>
<View style=>
<View>
<Text>{item.time.split(" ")[1]}</Text>
<Image source=
style=
/>
<Text>{item.temp_c + '℃'}</Text>
</View>
))}
</View>
</ScrollView>
)
}
}Here is the json

}I would like to loop through the hourly weather and then if the current time is the same or greater than the time in the json I would like the display the information within the app.
Is there any way of doing this?
from if statement after looping through json in React Native
