Dans un conteneur docker

Exemple de fichier docker-compose.yml

Il conviendra de créer les dossiers locaux correspondant au montage, ici :

/opt/projects/data/n8n_config
/opt/projects/data/n8n_node_modules

Ajout de module node

Exemple pour le module web_push afin qu'il soit exploitable dans un noeud "Code" de n8n :

docker exec -it nom_de_votre_conteneur_n8n /bin/sh -c "npm install -g web-push"

Dans le noeud "Code" il suffit de le déclarer ensuite pour pouvoir l'utiliser :

const webpush = require('web-push');
