Readme
Babel Root Import
Babel plugin to add the opportunity to use import
and require
with root based paths.
Example
// Usually
import SomeExample from '../../../some/example.js';
const OtherExample = require('../../../other/example.js');
// With Babel-Root-Importer
import SomeExample from '~/some/example.js';
const OtherExample = require('~/other/example.js');
Install
npm
npm install babel-plugin-root-import --save-dev
yarn
yarn add babel-plugin-root-import --dev
Use
Add a .babelrc
file and write:
{
"plugins": [
["babel-plugin-root-import"]
]
}
or pass the plugin with the plugins-flag on CLI
babel-node myfile.js --plugins babel-plugin-root-import
Extras
Custom root-path-suffix
If you want a custom root because for example all your files are in the src/js folder you can define this in your .babelrc
file
{
"plugins": [
["babel-plugin-root-import", {
"rootPathSuffix": "src/js"
}]
]
}
Custom root-path-prefix
If you don't like the ~
syntax you can just use your own symbol (for example a @
symbol or \
)
{
"plugins": [
["babel-plugin-root-import", {
"rootPathPrefix": "@"
}]
]
}
// Now you can use the plugin like:
import foo from '@/my-file';
Multiple custom prefixes and suffixes
You can supply an array of the above. The plugin will try each prefix/suffix pair in the order they are defined.
{
"plugins": [
["babel-plugin-root-import", [{
"rootPathPrefix": "~", // `~` is the default so you can remove this if you want
"rootPathSuffix": "src/js"
}, {
"rootPathPrefix": "@",
"rootPathSuffix": "other-src/js"
}, {
"rootPathPrefix": "#",
"rootPathSuffix": "../../src/in/parent" // since we suport relative paths you can also go into a parent directory
}]]
]
}
// Now you can use the plugin like:
import foo from '~/my-file';
const bar = require('@/my-file');
Don't let ESLint be confused
If you use eslint-plugin-import to validate imports it may be necessary to instruct ESLint to parse root imports. You can use eslint-import-resolver-babel-plugin-root-import
"import/resolver": {
"babel-plugin-root-import": {}
}
Don't let Flow be confused
If you use Facebook's Flow for type-checking it is necessary to instruct it on how to map your chosen prefix to the root directory. Add the following to your .flowconfig
file, replacing {rootPathPrefix}
with your chosen prefix and {rootPathSuffix}
with your chosen suffix.
[options]
module.name_mapper='^{rootPathPrefix}/\(.*\)$' -> '<PROJECT_ROOT>/{rootPathSuffix}/\1'
FYI
Webpack delivers a similar feature, if you just want to prevent end-less import strings you can also define aliases
in the resolve
module, at the moment it doesn't support custom/different symbols and multiple/custom suffixes.

Want to revert back to relative paths?
Sometimes tooling might not be up to scratch, meaning you lose features such as navigation in your IDE. In such cases you might want to revert back to using relative paths again. If you have a significant amount of files, it might be worth looking into tooling to help you with the conversion.
