node-red-node-leveldb
A Node-RED node to read and write to a LevelDB database.
Install
Run the following command in your Node-RED user directory - typically ~/.node-red
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.
