babel-plugin-module-resolver
A Babel plugin to add a new resolver for your modules when compiling your code using Babel. This plugin allows you to add new "root" directories that contain your modules. It also allows you to setup a custom alias for directories, specific files, or even other npm modules.
Description
This plugin can simplify the require/import paths in your project. For example, instead of using complex relative paths like ../../../../utils/my-utils
, you can write utils/my-utils
. It will allow you to work faster since you won't need to calculate how many levels of directory you have to go up before accessing the file.
// Use this:
import MyUtilFn from 'utils/MyUtilFn';
// Instead of that:
import MyUtilFn from '../../../../utils/MyUtilFn';
// And it also work with require calls
// Use this:
const MyUtilFn = require('utils/MyUtilFn');
// Instead of that:
const MyUtilFn = require('../../../../utils/MyUtilFn');
Getting started
Install the plugin
npm install --save-dev babel-plugin-module-resolver
or
yarn add --dev babel-plugin-module-resolver
Specify the plugin in your .babelrc
with the custom root or alias. Here's an example:
{
"plugins": [
["module-resolver", {
"root": ["./src"],
"alias": {
"test": "./test",
"underscore": "lodash"
}
}]
]
}
.babelrc.js version
Specify the plugin in your .babelrc.js
file with the custom root or alias. Here's an example:
const plugins = [
[
require.resolve('babel-plugin-module-resolver'),
{
root: ["./src/"],
alias: {
"test": "./test"
}
}
]
];

Documentation
babel-plugin-module-resolver can be configured and controlled easily, check the documentation for more details
Are you a plugin author (e.g. IDE integration)? We have documented the exposed functions for use in your plugins!
ESLint plugin
If you're using ESLint, you should use eslint-plugin-import, and eslint-import-resolver-babel-module to remove falsy unresolved modules. If you want to have warnings when aliased modules are being imported by their relative paths, you can use eslint-plugin-module-resolver.
Editors autocompletion
- Atom: Uses atom-autocomplete-modules and enable the
babel-plugin-module-resolver
option. - VS Code: Configure the path mapping in
jsconfig.json
(tsconfig.json
for TypeScript), e.g.:
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"*": ["src/*"],
"test/*": ["test/*"],
"underscore": ["lodash"]
}
}
}
- IntelliJ/WebStorm: You can mark your module directories as "resources root" e.g if you have
../../../utils/MyUtilFn
you can mark../../../utils
as "resources root". This has the problem that your alias also has to be namedutils
. The second option is to add awebpack.config.js
to your project and use it under File->Settings->Languages&Frameworks->JavaScript->Webpack. This will trick webstorm into resolving the paths and you can use any alias you want e.g.:
var path = require('path');
module.exports = {
resolve: {
extensions: ['.js', '.json', '.vue'],
alias: {
utils: path.resolve(__dirname, '../../../utils/MyUtilFn'),
},
},
};
