normalize-url
A JavaScript library for normalizing URLs by adding protocols, removing duplicates, sorting parameters, and stripping unnecessary components.
What is normalize-url?
normalize-url is a JavaScript library that converts URLs into a standardized format by adding missing protocols, removing unnecessary components like 'www' and tracking parameters, sorting query strings, and ensuring consistency. It solves the problem of URL variability when comparing, storing, or deduplicating web addresses.
Developers working with web data, crawlers, analytics, or applications that need to handle URLs consistently, such as those building deduplication systems, comparison tools, or data pipelines.
It offers a comprehensive, configurable solution for URL normalization with sensible defaults, supporting custom protocols and fine-grained control over every URL component, unlike simpler string-based approaches.
