Fetch the current file and directory path, no matter your environment

filedirname

Fetch the current file and directory path, no matter your environment (Deno, Node.js, Web Browsers, ESM, CJS)

Usage

Without Arguments

The following works for ESM (ECMAScript Modules) and CJS (CommonJS Modules) enviroments:

// for deno
import filedirname from 'https://unpkg.com/filedirname/edition-deno/index.ts'
// for web browsers
import filedirname from 'https://unpkg.com/filedirname'
// for node.js
import filedirname from 'filedirname'
// for commonjs
const filedirname = require('filedirname').default

// usage
const [__filename, __dirname] = filedirname()
console.log({ __filename, __dirname })

Via Error

The following works for ESM (ECMAScript Modules) and CJS (CommonJS Modules) environments:

// for deno
import filedirname from 'https://unpkg.com/filedirname/edition-deno/index.ts'
// for web browsers
import filedirname from 'https://unpkg.com/filedirname'
// for node.js
import filedirname from 'filedirname'
// for commonjs
const filedirname = require('filedirname').default

// usage
const [__filename, __dirname] = filedirname(new Error())
console.log({ __filename, __dirname })

Via `import.meta.url`

The following works only for ESM (ECMAScript Modules) environments and is the quickest solution:

// for deno
import filedirname from 'https://unpkg.com/filedirname/edition-deno/index.ts'
// for web browsers
import filedirname from 'https://unpkg.com/filedirname'
// for node.js
import filedirname from 'filedirname'

// usage
const [__filename, __dirname] = filedirname(import.meta.url)
console.log({ __filename, __dirname })
