module

Options for resolving module entry points in installed modules (import foo from 'bar').

Must be set to an object to be enabled. That object may contain the following options.

module.entry

A list of entry point resolvers.

[
	{
		"type": "package.json",
		"field": "module",
		"extensions": [".mjs", ".js"]
	},
	{
		"type": "file",
		"path": "./module",
		"extensions": [".mjs", ".js"]
	}
]

submodule.ignoreExports

Set to true to ignore any modules that have an exports entry (very important).

Examples

Example package.json field module

.babelrc

{
	"presets": [
		[
			"@babel/preset-env",
			{
				"modules": false,
				"targets": {
					"node": "current"
				}
			}
		]
	],
	"plugins": [
		[
			"esm-resolver",
			{
				"module": {
					"entry": [
						{
							"type": "package.json",
							"field": "module",
							"extensions": [".mjs", ".js"]
						}
					],
					"ignoreExports": true
				}
			}
		]
	]
}

src/main.js

import {foo} from 'bar';

output:

import {foo} from 'bar/lib/index.mjs';

Example file path ./module

.babelrc

{
	"presets": [
		[
			"@babel/preset-env",
			{
				"modules": false,

				}
			}
		]
	],
	"plugins": [

							"path": "./module",
							"extensions": [".mjs", ".js"]
						}
					],
