extensionless

Node.js loader for import specifiers as file paths without extensions or as directory paths

 

Install:

npm i extensionless

 

Start node with the following flag added:

--experimental-loader=extensionless

 

You can now use import specifiers as file paths without extensions or as directory paths:

// imports from the first existing file in the candidates list as follows

import mod from './mod'
// ['./mod.js', './mod/index.js']

import mod from './mod' assert {type: 'json'}
// ['./mod.json', './mod/index.json']

 

If the specifier ends with a path separator, it only looks for index files in that directory:

// imports from the first existing file in the candidates list as follows

import mod from '../mod/'
// ['../mod/index.js']

import mod from '../mod/' assert {type: 'json'}
// ['../mod/index.json']

 

To configure this package, you can add the field extensionless to package.json:

"extensionless": {
  "lookFor": ["js", "mjs", "cjs"]
}

Field	Default Value
lookFor	["js"]
