URL Parser

A URL parser breaks a URL into its named components: scheme (https), host (example.com), port, path (/blog/post), query parameters (?id=5&sort=new — split into individual key-value pairs), and fragment (#section). It reveals the anatomy of a URL that looks like one string but is really a structured address.

URLs pack a lot into a small space, and parsing untangles it — especially query strings, where multiple parameters cram together and the parser separates them into a readable list of what each one is and holds.

Paste a URL and see it decomposed — each component labeled, query parameters listed individually.

Where parsing helps: debugging query parameters — a URL with a dozen tracking and functional parameters becomes a clear table of what's being passed (utm_source, page IDs, filters, session tokens); understanding URL structure — learning how a URL is built, which components exist, what the fragment vs query does; API and integration work — verifying an endpoint's parts, extracting a specific parameter's value, checking the path structure; and SEO and analytics — seeing exactly which parameters a URL carries (and whether they're creating duplicate-content variants that need canonical tags).

Component meanings worth knowing: the fragment (#anchor) is client-side only — browsers use it to scroll, servers never receive it; the query (?key=value) IS sent to the server and drives behavior; and the port is usually implied (443 for https, 80 for http) unless specified.
