What is babel-plugin-module-resolver?
The babel-plugin-module-resolver npm package allows you to customize the resolution of modules in your Babel projects. It can be used to alias paths, so you don't have to deal with relative paths, and it can also help in organizing the project's structure more logically from a developer's perspective.
What are babel-plugin-module-resolver's main functionalities?
Custom Aliases
This feature allows you to define custom aliases for directories within your project. Instead of using relative paths, you can use the aliases to require modules, making the code cleaner and easier to maintain.
{
"plugins": [
["module-resolver", {
"alias": {
"@app": "./src/app",
"@models": "./src/models"
}
}]
]
}
Extension Resolution
This feature enables you to specify which file extensions should be resolved by the plugin. This can be useful when you are working with different types of JavaScript files and want to import them without specifying the extension.
{
"plugins": [
["module-resolver", {
"extensions": [
".js",
".jsx"
]
}]
]
}
Root Directory Configuration
By setting a root directory, you can simplify the import statements in your project. This feature allows you to set a base directory from which all the modules will be resolved.
{
"plugins": [
["module-resolver", {
"root": ["./src"]
}]
]
}
Other packages similar to babel-plugin-module-resolver
tsconfig-paths-webpack-plugin
This package is used with webpack to automatically resolve modules based on the paths defined in tsconfig.json. It is similar to babel-plugin-module-resolver but is specifically tailored for TypeScript projects using webpack.
eslint-import-resolver-alias
This package is an ESLint resolver that allows you to configure aliases for module paths, similar to babel-plugin-module-resolver. It is used to help ESLint understand the custom path aliases defined in your project.
aliasify
Aliasify is a Browserify transform that provides similar aliasing functionality to babel-plugin-module-resolver. It allows you to rewrite module calls in your Browserify bundles, but it is specific to the Browserify ecosystem.
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.
import MyUtilFn from 'utils/MyUtilFn';
import MyUtilFn from '../../../../utils/MyUtilFn';
const MyUtilFn = require('utils/MyUtilFn');
const MyUtilFn = require('../../../../utils/MyUtilFn');
Getting started
Install the plugin
$ npm install --save-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"
}
}
]
];

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. - IntelliJ/WebStorm: You can add custom resources root directories, make sure it matches what you have in this plugin.
- VS Code: Configure the path mapping in
jsconfig.json
(tsconfig.json
for TypeScript), e.g.:
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"*": ["src/*"],
"test/*": ["test/*"],
"underscore": ["lodash"]
}
}
