JSPM – extensionless@1.4.3

Package Exports

extensionless
extensionless/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (extensionless) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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']

import api from '/apps/api'
// ['/apps/api.js', '/apps/api/index.js']

import web from 'file:///apps/web'
// ['file:///apps/web.js', 'file:///apps/web/index.js']

To configure the module, add the field extensionless to your project's package.json:

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

Field	Default Value
`lookFor`	`["js"]`

When it can be deduced from the specifier that its target is a directory, the resolver looks for only the index files:

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

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

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

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

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

import api from '/apps/api/'
// ['/apps/api/index.js']

import web from 'file:///apps/web/'
// ['file:///apps/web/index.js']

This loader also adds support for Windows path resolution with which you can use forward or backward slashes as separators.

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

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

import api from 'C:/apps/api'
// ['/C:/apps/api.js', '/C:/apps/api/index.js']

import web from 'C:\\apps\\web\\'
// ['/C:/apps/web/index.js']
