Help Curl, Javascript/NodeJs

[Nenatik]

Bonjour depuis quelle jour je me suis lancer dans le développement d’une app utilisant l’api te twitter et l’api spotify, après quelle jour a galérer pour automatiser l’obtention de mon l’access token spotify, je veux essayer de récupérer le tracks du top 1 des charts spotify jusqu’à la rien de dur utilisation de curl et de child process de node js :

let execPlaylist = 'curl -X GET "https://api.spotify.com/v1/playlists/37i9dQZEVXbIPWwFssbupI/tracks?limit=1&offset=0" -H "Authorization: Bearer ' + AccessToken.AccessToken + '"'

exec(execPlaylist, (err, stdout, stderr) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(stdout);
});

et cela me donne :

donc je me demande comment en utilisant javascript je peux extraire des information tels que le nom du tracks et autre et le mettre par exemple dans une variable (je suis débutant en javascript et j’utilise cette application en grande parti pour apprendre le javascript)

[Haeresis]

Si vous êtes débutant en JavaScript, je vous conseil alors de faire une petite pause pour lire ce contenu en français et très complet : Table des matières -- JavaScript Éloquent

Je suis sur qu’il saura répondre à vos questions.

Par exemple le code suivant :

const trackName = stdout.items[0].track.name;
console.log(trackName)

affichera le nom « Djomb - Bien ou quoi »

Note : il faut plutôt utiliser JSON.parse(stdout).items[0].track.name; si stdout est une stringet non unObject`.
