node-red-node-leveldb

A Node-RED node to read and write to a LevelDB database.

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-node-leveldb

Usage

Allows basic access to a LevelDB database.

Uses LevelDB for a simple key value pair database.

There are two node to choose from...

Use one node to either put (store) the msg.payload to the named database file, using msg.topic as the key, or to delete information select delete in the properties dialogue and again use msg.topic as the key..

Use the other node to get, or retrieve the data already saved in the database.

Again use msg.topic to hold the key for the database, and the result is returned in msg.payload. If nothing is found for the key then null is returned.
