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.
