n8n-nodes-firestore-database

Community node for n8n that connects to Firebase Firestore using a Service Account.
Read, write, update, delete and query documents.

Features

• Get / Create / Update / Delete document
• Query collection (where, orderBy, limit)
• Add document to collection (auto-id) or set a specific docId
• Supports nested paths like users/{userId}/orders/{orderId}
• Automatic conversion for basic JSON values

Credentials (Service Account)

Create a Firebase Service Account with role Firebase Admin SDK Administrator Service Agent (or minimally Firestore Admin permissions).
Upload or paste these fields into the credential in n8n:

• projectId
• clientEmail
• privateKey (paste as-is; both plain multi-line and \n escaped are supported)

Usage tips

• Paths are always relative to the root (no leading slash). Example: users/123 or users/123/orders.
• For queries, set the collection path (e.g. users) and your conditions.

Development

npm install
npm run build
# symlink into your n8n custom folder or copy dist files
