basename

import { basename } from "jsr:@ende/path/posix/basename";

function

function basename(path: string | URL, suffix: string = ): string

Return the last portion of a path. Trailing directory separators are ignored, and optional suffix is removed.

path: string | URL: The path to extract the name from.
suffix: string =: The suffix to remove from extracted name.

Returns

The extracted name.

Example: Usage

import { basename } from "@ende/path/posix/basename";
import { assertEquals } from "@ende/assert";

assertEquals(basename("/home/user/Documents/"), "Documents");
assertEquals(basename("/home/user/Documents/image.png"), "image.png");
assertEquals(basename("/home/user/Documents/image.png", ".png"), "image");
assertEquals(basename(new URL("file:///home/user/Documents/image.png")), "image.png");
assertEquals(basename(new URL("file:///home/user/Documents/image.png"), ".png"), "image");

Example: Working with URLs

Only URL instances with the file: protocol are accepted. To process a non-file: URL, pass it as a string or pass its pathname property.

Note: This function doesn't automatically strip hash and query parts from URLs. If your URL contains a hash or query, remove them before passing the URL to the function. This can be done by passing the URL to new URL(url), and setting the hash and search properties to empty strings.

import { basename } from "@ende/path/posix/basename";
import { assertEquals } from "@ende/assert";

assertEquals(basename("https://ende.sh/std/path/mod.ts"), "mod.ts");
assertEquals(basename("https://ende.sh/std/path/mod.ts", ".ts"), "mod");
assertEquals(basename("https://ende.sh/std/path/mod.ts?a=b"), "mod.ts?a=b");
assertEquals(basename("https://ende.sh/std/path/mod.ts#header"), "mod.ts#header");
assertEquals(basename(new URL("https://ende.sh/std/path/mod.ts").pathname), "mod.ts");
