How can I convert a windows path to posix path using node path

Question

I\'m developing on windows, but need to know how to convert a windows path (with backslashes \\) into a POSIX path with forward slashes (/)?

Answer 1

A one-liner mimicking slash and upath (see the multi-liner version for proof of validity)

//
// one-liner
//
let convertPath = (windowsPath) => windowsPath.replace(/^\\\\\?\\/,"").replace(/\\/g,'\/').replace(/\/\/+/g,'\/')

//
// usage
//
convertPath("C:\\repos\\vue-t\\tests\\views\\index\\home.vue")
// >>> "C:/repos/vue-t/tests/views/index/home.vue"

//
// multi-liner (commented and compatible with really old javascript versions)
//
function convertPath(windowsPath) {
    // handle the edge-case of Window's long file names
    // See: https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file#short-vs-long-names
    windowsPath = windowsPath.replace(/^\\\\\?\\/,"");

    // convert the separators, valid since both \ and / can't be in a windows filename
    windowsPath = windowsPath.replace(/\\/g,'\/');

    // compress any // or /// to be just /, which is a safe oper under POSIX
    // and prevents accidental errors caused by manually doing path1+path2
    windowsPath = windowsPath.replace(/\/\/+/g,'\/');

    return windowsPath;
};

// dont want the C: to be inluded? here's a one-liner for that too
let convertPath = (windowsPath) => windowsPath.replace(/^\\\\\?\\/,"").replace(/(?:^C:)?\\/g,'\/').replace(/\/\/+/g,'\/')

Answer 2

const winPath = 'C:\\repos\\vue-t\\tests\\views\\index\\home.vue'
const posixPath = winPath.replace(/\\/g, '/').slice(2)
// Now posixPath = '/repos/vue-t/tests/views/index/home.vue'

Answer 3

Slash converts windows backslash paths to Unix paths

Usage:

const path = require('path');
const slash = require('slash');

const str = path.join('foo', 'bar');

slash(str);
// Unix    => foo/bar
// Windows => foo/bar

Answer 4

There is node package called upath will convert windows path into unix.

upath = require('upath');

or

import * as upath from 'upath';

upath.toUnix(destination_path)

Answer 5

Given that all the other answers rely on installing (large) third party modules: this can also be done as a one-liner for relative paths (which you should be using 99.999% of the time) using Node's standard library path module, and more specifically, taking advantage of its dedicated path.posix and path.win32 namespaced properties/functions:

const path = require("path");

// ...

const definitelyPosix = somePathString.split(path.sep).join(path.posix.sep);

This will convert your path to POSIX format irrespective of whether you're already on POSIX platforms, or on win32, while requiring zero dependencies.
