node-red-node-alchemy-sentiment

Node-RED node to work with the alchemy API to provide sentiment analysis of text. Works on the msg.payload passed in and returns the result as JSON in msg.alchemy field. You must first register with alchemyapi.com and get an API key to use this node.

Install

Install from npm

npm install node-red-node-alchemy-sentiment

Usage:

-- API key: Paste in your key here. If you do not have one, you can register for your API key at alchemyapi.com. If you have multiple alchemy sentiment nodes, you only need to configure this for one and the others will reference the same key.

-- Target: Optionally enter a target to give context to the sentiment analysis. If you do not specify a target, your sentiment analysis will be general.
