Path (@std/path)

@std/path manipulates filesystem paths as strings (POSIX / separators). It performs no I/O.

import { join, basename, extname } from "@std/path";

console.log(join(["usr", "local", "bin"]));   // usr/local/bin
console.log(basename("/etc/hosts"));          // hosts
console.log(extname("archive.tar.gz"));       // .gz

Node’s variadic join(...parts) / resolve(...parts) take a string[] here, since Zeus free functions are not variadic.

Reference

join(parts: string[]): string          // join + normalize
resolve(parts: string[]): string       // to an absolute path, using process.cwd()
normalize(p: string): string           // collapse "."/".."/duplicate slashes
dirname(p: string): string             // directory portion
basename(p: string): string            // final segment
extname(p: string): string             // extension incl. dot, or ""
isAbsolute(p: string): boolean
relative(fromPath: string, toPath: string): string
parse(p: string): ParsedPath           // { root, dir, base, ext, name }
format(pp: ParsedPath): string         // inverse of parse
sep(): string                          // "/"
delimiter(): string                    // ":"

import { parse, ParsedPath } from "@std/path";

let pp: ParsedPath = parse("/usr/local/zeus.tar.gz");
console.log(pp.dir);   // /usr/local
console.log(pp.base);  // zeus.tar.gz
console.log(pp.ext);   // .gz
console.log(pp.name);  // zeus.tar
