Je développe une application musicale en Node.js qui gère des morceaux de musique (tracks). Voici l'architecture actuelle des données :Tracks : Morceaux de musique stockés sous forme de fichiers audio.
|
||||
Playlists : Ensembles de tracks regroupés dans un dossier spécifique sur le disque (ex. : un dossier par playlist). Actuellement, à chaque requête, le serveur scanne récursivement le dossier pour lister les tracks, ce qui génère la playlist dynamiquement.
|
||||
Compilations : Ensembles de tracks mixés ensemble, représentant un seul fichier audio unifié. Actuellement, les compilations sont hardcodées dans le code (pas de scan dynamique).
|
||||
|
||||
Problèmes actuels :Performances : Le scan des dossiers pour les playlists prend ~6 secondes par requête, ce qui est inacceptable pour une bonne UX.
|
||||
Manque d'uniformité : Les playlists sont générées dynamiquement (lourd), tandis que les compilations sont statiques (hardcodées), rendant la maintenance difficile.
|
||||
Pas de persistance : Aucune base de données, donc pas de cache ni de requêtes rapides.
|
||||
|
||||
Objectifs :Utiliser une base de données SQLite comme cache pour stocker les métadonnées des tracks, playlists et compilations, afin d'éviter les scans disque à chaque requête.
|
||||
Uniformiser l'architecture : Stocker à la fois les playlists (issues de scans de dossiers) et les compilations en base.
|
||||
Améliorer les performances : Les requêtes doivent renvoyer les données depuis la DB en <1 seconde, avec un scan disque initial ou périodique pour mise à jour.
|
||||
ORM : Utiliser Drizzle ORM pour interagir avec SQLite (facile à setup en Node.js).
|
||||
Schéma DB suggéré (à affiner si needed) :
|
||||
Table tracks : id, title, artist, duration, file_path (chemin du fichier), source_type ('playlist' ou 'compilation'), source_id (FK vers playlist ou compilation).
|
||||
Table compilations : id, name, file_path (chemin du fichier mixé), tracks_list (JSON ou relation many-to-many si needed).
|
||||
|
||||
Contraintes techniques :DB : SQLite uniquement (fichier local, pas de serveur).
|
||||
Environnement : Node.js (version récente, ex. 18+). Pas d'installation de paquets incompatibles. Deployable dans une app Nuxt 4, la partie typescript sera écrite dans le dossier server prevu dans nuxt avec h3.
|
||||
Gestion des mises à jour : Implémenter un mécanisme pour re-scanner les dossiers playlists seulement si des changements sont détectés (ex. : via fs.watch ou comparaison de timestamps). Pour les compilations, permettre un import manuel ou initial.
|
||||
Population initiale : Au démarrage de l'app, scanner les dossiers playlists et importer les compilations hardcodées actuelles en DB.
|
||||
|
||||
Output attendu :Étapes détaillées pour implémenter cela (setup DB, schéma avec Drizzle, code pour population initiale et mises à jour).
|
||||
Exemples de code Node.js : Setup de Drizzle avec SQLite.
|
||||
Fonctions pour scanner le dossier playlists
|
||||
Exemples de requêtes (ex. : getPlaylistById depuis DB, avec fallback sur scan si cache invalide).
|
||||
Gestion des erreurs et optimisations perf.
|
||||
|
||||
Si possible, un schéma DB en SQL ou Drizzle schema.ts.
|
||||
Assure-toi que la solution est scalable pour ~1000 tracks initiaux, et teste les perfs dans tes exemples.
