🚀 WeeDB: Persistent Data Storage for n8n

🎯 The Problem

One of the most challenging aspects of n8n custom node development has been persistent data storage. Common issues include:

• Data loss during node updates
• No built-in persistent storage solution
• State management complexity

💡 The Solution

WeeDB solves these challenges by providing:

1. True Persistence

   • Data stored in user's home directory (~/.weedb/)
   • Survives node updates and reinstalls
   • Cross-platform compatibility

2. Simple API

   // Store data that persists!
   await weeDB.create({ key: "settings", value: "important-data" });
   

3. Reliable Architecture

   ~/.weedb/
   ├── database1.json
   ├── database2.json
   └── settings/
       └── config.json
   

⚡ Features

1. Persistent Storage

• ✅ Survives node updates
• ✅ Survives n8n restarts
• ✅ Cross-platform support

2. Rich Operations

• 🔍 Pattern-based search
• 🗑️ Bulk operations
• 🔄 Atomic updates

3. Safety Features

• 🧪 Dry run mode
• ⚠️ Operation confirmation
• 🔒 Data integrity checks

🛠️ Installation

npm install n8n-nodes-weedb
