What is string-similarity?

The string-similarity npm package provides functions to find the similarity between strings and to find the best match among a set of strings compared to a target string. It uses various algorithms to calculate a similarity score and can be used in applications such as fuzzy matching, search optimizations, and data deduplication.

What are string-similarity's main functionalities?

Comparing two strings for similarity

This feature allows you to compare two strings and get a similarity score between 0 and 1, where 1 means the strings are identical.

const stringSimilarity = require('string-similarity');
const similarity = stringSimilarity.compareTwoStrings('string1', 'string2');

Finding the best match in an array of strings

This feature allows you to compare a target string against an array of strings and find the one that is most similar to the target. It returns an object with the best match and ratings for all strings.

const stringSimilarity = require('string-similarity');
const matches = stringSimilarity.findBestMatch('string', ['string1', 'string2', 'string3']);
