| 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');
