deno-path-from-file-url

Convert file URLs to paths.

The functionality is bundled from @std/path.

Install

yarn add deno-path-from-file-url

Usage

import process from 'node:process'
import assert from 'node:assert/strict'
import fromFileUrl from 'deno-path-from-file-url'

if (process.platform === 'win32') {
  assert.equal(fromFileUrl('file:///home/foo'), String.raw`\home\foo`)
  assert.equal(fromFileUrl('file:///C:/Users/foo'), String.raw`C:\Users\foo`)
  assert.equal(fromFileUrl('file://localhost/home/foo'), String.raw`\home\foo`)
} else {
  assert.equal(fromFileUrl('file:///home/foo'), '/home/foo')
}

For POSIX-specific functions:

import assert from 'node:assert/strict'
import fromFileUrl from 'deno-path-from-file-url/posix'

assert.equal(fromFileUrl('file:///home/foo'), '/home/foo')

For Windows-specific functions:

import assert from 'node:assert/strict'
import fromFileUrl from 'deno-path-from-file-url/windows'

assert.equal(fromFileUrl('file:///home/foo'), String.raw`\home\foo`)
assert.equal(fromFileUrl('file:///C:/Users/foo'), String.raw`C:\Users\foo`)
assert.equal(fromFileUrl('file://localhost/home/foo'), String.raw`\home\foo`)

Motivation

Prettier need this functionality, can't use node:url.fileURLToPath() since it runs in both Node.js and browsers, can't install @std/path either since Prettier supports install from GitHub and not all NPM clients support jsr: protocol.
