Installation (CJS/ESM/TypeScript)

npm install os-paths
# or... `npm install "git:github.com/rivy/js.os-paths"`
# or... `npm install "git:github.com/rivy/js.os-paths#v6.3.0"`
# or... `npm install "https://cdn.jsdelivr.net/gh/rivy/js.os-paths/dist/os-paths.tgz"`

Usage

CommonJS (CJS)

const osPaths = require('os-paths/cjs');
const home = osPaths.home();
const temp = osPaths.temp();

ECMAScript (ESM)/TypeScript

import osPaths from 'os-paths';
const home = osPaths.home();
const temp = osPaths.temp();

Deno

import osPaths from 'https://deno.land/x/os_paths/src/mod.deno.ts';
//or...
//import osPaths from 'https://deno.land/x/os_paths@v6.3.0/src/mod.deno.ts';
//or (via CDN, with optional version/version-range/latest/commit support)...
//import osPaths from 'https://cdn.jsdelivr.net/gh/rivy/js.os-paths@6.3.0/src/mod.deno.ts'; // v6.3.0
//import osPaths from 'https://cdn.jsdelivr.net/gh/rivy/js.os-paths@6/src/mod.deno.ts'; // v6.x.y
//import osPaths from 'https://cdn.jsdelivr.net/gh/rivy/js.os-paths/src/mod.deno.ts'; // latest
//import osPaths from 'https://cdn.jsdelivr.net/gh/rivy/js.os-paths@latest/src/mod.deno.ts'; // latest
//import osPaths from 'https://cdn.jsdelivr.net/gh/rivy/js.os-paths@COMMIT/src/mod.deno.ts'; // commit
const home = osPaths.home();
const temp = osPaths.temp();

API

Construction/Initialization

OSPaths()

const osPaths = require('os-paths/cjs'); // CJS
//or...
//import osPaths from 'os-paths'; // ESM/TypeScript
//import osPaths from 'https://deno.land/x/os_paths/src/mod.deno.ts'; // Deno

When importing this module, the object returned is a function object, OSPaths, augmented with attached methods. Additional OSPaths objects may be constructed by direct call of the imported OSPaths object (eg, const p = osPaths()) or by using new (eg, const p = new osPaths()). Notably, since the OSPaths object contains no instance state, all OSPaths objects will be functionally identical.

Methods

All methods return simple, platform-specific, and platform-compatible path strings which are normalized and have no trailing path separators.

The returned path strings are not guaranteed to already exist on the file system. So, the user is responsible for directory construction, if/when needed. However, since all of these are standard OS directories, they should all exist without the need for user intervention.

If/when necessary, make-dir or mkdirp can be used to create the directories.

osPaths.home(): string | undefined

  • Returns the path string of the user's home directory (or undefined if the user's home directory is not resolvable).
console.log(osPaths.home());
//(*nix) => '/home/rivy
//(windows) =>  'C:\Users\rivy'

osPaths.temp(): string

  • Returns the path string of the system's default directory for temporary files.
console.log(osPaths.temp());
//(*nix) => '/tmp'
//(windows) =>  'C:\Users\rivy\AppData\Local\Temp'

temp() will always return a non-empty path string (as sanely as possible).

Supported Platforms

NodeJS

Requirements

NodeJS >= 4.0[^*]

[^*]: With the conversion to a TypeScript-based project, due to tooling constraints, building and testing are more difficult and more limited on Node platforms earlier than NodeJS-v10. However, the generated CommonJS/UMD project code is fully tested (for NodeJS-v10+) and continues to be compatible with NodeJS-v4+.

CommonJS modules (CJS; *.js and *.cjs)

CJS is the basic supported output (with support for NodeJS versions as early as NodeJS-v4).

const osPaths = require('os-paths/cjs');
console.log(osPaths.home());
console.log(osPaths.temp());

Note: for CJS, require('os-paths') is supported for backward-compatibility and will execute correctly at run-time. However, this require construction links to the default package type declarations which, though correct for Deno/ESM/TypeScript, are incorrect for CJS. This, then, leads to incorrect analysis of CJS files by static analysis tools such as TypeScript and Intellisense.

Using require('os-paths/cjs') is preferred as it associates the proper CJS type declarations and provides correct information to static analysis tools.

ECMAScript modules (ESM; *.mjs)

  • Requires v6.0+.

OSPaths fully supports ESM imports.

import osPaths from 'os-paths';
console.log(osPaths.home());
console.log(osPaths.temp());

TypeScript (*.ts)

  • Requires v5.0+.

As of v5.0+, OSPaths has been converted to a TypeScript-based module. As a consequence, TypeScript type definitions are automatically generated, bundled, and exported by the module.

Deno

  • Requires v6.0+.

OSPaths also fully supports use by Deno.

import osPaths from 'https://deno.land/x/os_paths/src/mod.deno.ts';
console.log(osPaths.home());
console.log(osPaths.temp());
