There is a more mature node.js module for NLP out there, but as both NLP and node.js are my hobbies I created this module to dig deeper into both topics.
npm install nlp-toolkit
var nlp = require("nlp-toolkit");
> nlp.tokenize("That is a tokenizer.");
[ 'That', 'is', 'a', 'tokenizer' ]
> nlp.tokenize("That is a tokenizer.", {
stopwords: 'english',
porter: true
};
'token'
