string-entropy
Calculate the information entropy of a string
As pointed out by other sources, string entropy is propably the most reliable way of scoring a password. This module implements the algorithm described here, using a variable sized alphabet based on the actual contents of the string.

See the annotated sources src/index.ts.
Example
var entropy = require('string-entropy');
console.log(entropy('correct horse battery staple'));
