I have nearly finished the Jammming project but my website will not show any results when I type into the search bar. I feel like it might be an error with calling the APIs from Spotify or with my methods. I am very new to Javascript so I’m unsure. Below is my code from the main JS files. I have not included my clientID and similar codes for obvious reasons.
App.js
import './App.css';
import Track from '../Track/Track.js';
import React from 'react';
import SearchBar from '../SearchBar/SearchBar';
import SearchResults from '../SearchResults/SearchResults';
import Playlist from '../Playlist/Playlist';
import Spotify from '../../util/Spotify';
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
SearchResults: [],
playlistName: 'My Playlist',
playlistTracks: []
};
this.addTrack = this.addTrack.bind(this);
this.removeTrack = this.removeTrack.bind(this);
this.updatePlaylistName = this.updatePlaylistName.bind(this);
this.savePlaylist = this.savePlaylist.bind(this);
this.search = this.search.bind(this);
}
addTrack(track) {
let tracks = this.state.playlistTracks;
if (tracks.find(savedTrack => savedTrack.id === track.id)) {
return;
}
tracks.push(track);
this.setState({ playlistTracks: tracks });
}
removeTrack(track) {
let tracks = this.state.playlistTracks;
if (tracks.find(savedTrack => savedTrack.id === track.id)) {
return;
}
tracks.pop(track);
this.setState({ playlistTracks: tracks });
}
updatePlaylistName(name) {
this.setState({ playlistName: name });
}
savePlaylist() {
const trackURIs = this.state.playlistTracks.map(track => track.uri);
Spotify.savePLayList(this.state.playlistName, trackURIs).then(() => {
this.setState({
playlistName: 'New Playlist',
playlistTracks: []
})
})
}
search(term) {
Spotify.search(term).then(searchResults => {
this.setState({searchResults: searchResults})
})
}
render() {
return (
<div>
