Utilities for working with URLs.

This module is browser compatible.

Get basename

basename returns the base name of a URL or URL string, optionally removing a suffix.

import { basename } from "https://deno.land/std@0.224.0/url/basename.ts";

basename("https://deno.land/std/assert/mod.ts"); // "mod.ts"

basename(new URL("https://deno.land/std/assert/mod.ts")); // "mod.ts"

basename("https://deno.land/std/assert/mod.ts?a=b"); // "mod.ts"

basename("https://deno.land/std/assert/mod.ts#header"); // "mod.ts"

basename("https://deno.land/"); // "deno.land"

Get directory path

dirname returns the directory path of a URL or URL string.

import { dirname } from "https://deno.land/std@0.224.0/url/dirname.ts";

dirname("https://deno.land/std/path/mod.ts?a=b").href; // "https://deno.land/std/path"

dirname("https://deno.land/").href; // "https://deno.land"

Get file extension

extname returns the file extension of a given URL or string with leading period.

import { extname } from "https://deno.land/std@0.224.0/url/extname.ts";

extname("https://deno.land/std/path/mod.ts"); // ".ts"

extname("https://deno.land/std/path/mod"); // ""

extname("https://deno.land/std/path/mod.ts?a=b"); // ".ts"

extname("https://deno.land/"); // ""

Join URL paths

join joins a base URL or URL string, and a sequence of path segments together, then normalizes the resulting URL.

import { join } from "https://deno.land/std@0.224.0/url/join.ts";

join("https://deno.land/", "std", "path", "mod.ts").href;
// "https://deno.land/std/path/mod.ts"

join("https://deno.land", "//std", "path/", "/mod.ts").href;
// "https://deno.land/path/mod.ts"

Normalize URL

normalize normalizes the URL or URL string, resolving .. and . segments. Multiple sequential /s are resolved into a single /.

import { normalize } from "https://deno.land/std@0.224.0/url/normalize.ts";

normalize("https:///deno.land///std//assert//.//mod.ts").href;
// "https://deno.land/std/path/mod.ts"

normalize("https://deno.land/std/assert/../async/retry.ts").href;
// "https://deno.land/std/async/retry.ts"
