fetchData = data => { this.setState({imgLink: data.items[0].snippet.thumbnails.default.url}); }

onPressedButton = channelId => { // fetch the value entered in the input field //alert(channelId); this.setState({channelId:channelId}) //fetch the value(channelId) that is enter in the input field // make a request var url = 'https://www.googleapis.com/youtube/v3/channels?key='+API_Key+'&id=' + this.state.channelId + '&part=snippet,contentDetails,statistics'; this.setState({url: url}); fetch(url,{ method: 'GET' }) .then((response) => response.json()) // fetchData(data); .then((data) => { fetchData(data); alert(imgLink); }) //now fetching the response from the yt api again and again .setInterval(() => { var url = 'https://www.googleapis.com/youtube/v3/channels?key='+API_Key+'&id=' + this.state.channelId + '&part=statistics'; fetch(url,{ method: 'GET' }) .then((response) => updateSubscribers(response.json())) },0)

.catch((error) => { console.log(error); }); }
