path.js

Browser-friendly enhanced path fully compatible with standard node.js path

A lightweight, cross-platform library for manipulating paths.

This package modifies and enhances the standard path from node.js

API

Path Class

import { Path } from 'path.js';

// Default constructor with optional string or object parameter
const myPath = new Path('custom_separator'); // String: sets custom path separator
const myPathWithOptions = new Path({
  sep: 'custom_separator', // Custom path separator
  delimiter: 'custom_delimiter', // Custom path delimiter
  splitPathReStr: 'custom_regular_expression', // Custom regular expression for splitting paths
});

Properties

• sep: The path separator character. Can be set at instantiation or later via a getter/setter.
• delimiter: The path delimiter character. Can be set at instantiation or later via a getter/setter.
• splitPathReStr: A string representing a regular expression used to split paths. Must include the placeholder &SEP&, which will be replaced with the current sep. Can be set at instantiation or later via a getter/setter.

Methods

• updateSplitPathRe(): Updates the internal splitPathRe regular expression based on the current splitPathReStr and sep.
• splitPath(filename): Splits a given filename using the current splitPathRe and returns the resulting array.
• toArray(aPath): Converts a given aPath to an array of path segments, trimming any leading or trailing empty elements.
• normalizeArray(parts, allowAboveRoot): Normalizes an array of path segments, resolving . and .. elements, and optionally allowing paths above the root.
• trimArray(arr): Removes leading and trailing empty elements from the given array.
• isAbsolute(path): Returns true if the given path is absolute, false otherwise.
• normalize(path): Normalizes the given path, resolving . and .. elements, removing redundant separators, and ensuring proper absolute or relative form.
• cwd(): Returns the current working directory as a string ('.' for default implementation).
• resolveArray(): Resolves a sequence of paths or path segments into an absolute path, taking the current working directory into account.
• _join(): Internal method for joining path segments, handling arrays and strings.
• join(): Joins multiple path segments into a single path, normalizing and resolving relative segments.
• _isSame(aDir1, aDir2): Compares two directories for equality, returning true if they are the same, false otherwise.
• relative(from, to): Computes the relative path from from to to.
• dirname(path): Extracts the directory name from the given path.
• basename(path, ext): Extracts the base name from the given path, optionally removing a specified extension.
• replaceExt(path, ext): Replaces the extension of the given path with a new one.
• extname(path): Extracts the extension from the given path.
• format(pathObject): Constructs a path string from an object with root, dir, and base properties.
• parse(pathString): Parses a path string into an object with root, dir, base, ext, and name properties.
• _makeLong(path): Returns the given path unchanged (internal placeholder for potential long path handling).

WinPath Class

import { WinPath } from 'path.js';
import path from 'path.js';

// path.win32
const winPath = new WinPath();

PosixPath class

import { PosixPath } from 'path.js';
import path from 'path.js';

// path.posix
const posixPath = new PosixPath();

Usage

import { Path, WinPath, PosixPath } from 'path.js';
import path from 'path.js';

// Using the default Path class
const _path = new Path();
console.log(_path.normalize('/path/to/../file.ext')); // '/path/file.ext'

// Using the WinPath subclass or path.win32
const winPath = new WinPath();

console.log(winPath.normalize('C:\\path\\to\\..\\file.ext')); // 'C:\path\file.ext'

// Using the PosixPath subclass or path.posix
const posixPath = new PosixPath();

console.log(posixPath.normalize('/path/to/../file.ext')); // '/path/file.ext'
