forked from https://bitbucket.org/amctheatres/babel-transform-imports

  • add replace option
  'react-icons': {
    transform: 'react-icons/lib/${member}',
    replace: ['^(..)-', '$1/'],
    kebabCase: true,

import { MdCheck, FaCheck } from 'react-icons'
import MdCheck from 'react-icons/lib/md/check'
import FaCheck from 'react-icons/lib/fa/check'


npm install @gutenye/babel-transform-imports

Transforms member style imports:

    import { Row, Grid as MyGrid } from 'react-bootstrap';
    import { merge } from 'lodash';

...into default style imports:

    import Row from 'react-bootstrap/lib/Row';
    import MyGrid from 'react-bootstrap/lib/Grid';
    import merge from 'lodash/merge';

That's stupid, why would you do that?

When Babel encounters a member style import such as:

    import { Grid, Row, Col } from 'react-bootstrap';

it will generate something similarish to:

    var reactBootstrap = require('react-bootstrap');
    var Grid = reactBootstrap.Grid;
    var Row = reactBootstrap.Row;
    var Col = reactBootstrap.Col;

Some libraries, such as react-bootstrap and lodash, are rather large and pulling in the entire module just to use a few pieces would cause unnecessary bloat to your client optimized (webpack etc.) bundle. The only way around this is to use default style imports:

    import Grid from 'react-bootstrap/lib/Grid';
    import Row from 'react-bootstrap/lib/Row';
    import Col from 'react-bootstrap/lib/Col';

But, the more pieces we need, the more this sucks. This plugin will allow you to pull in just the pieces you need, without a separate import for each item. Additionally, it can be configured to throw when somebody accidentally writes an import which would cause the entire module to resolve, such as:

    import Bootstrap, { Grid } from 'react-bootstrap';
    // -- or --
    import * as Bootstrap from 'react-bootstrap';


npm install --save-dev babel-plugin-transform-imports


In .babelrc:

        "plugins": [
            ["transform-imports", {
                "react-bootstrap": {
                    "transform": "react-bootstrap/lib/${member}",
                    "preventFullImport": true
                "lodash": {
                    "transform": "lodash/${member}",
                    "preventFullImport": true

That's it!

Note: this plugin is not restricted to the react-bootstrap and lodash libraries. You may use it with any library, where the options keys (react-bootstrap and lodash above) are the actual names of the libraries.


Name Type Required Default Description
transform string yes undefined The library name to use instead of the one specified in the import statement. ${member} will be replaced with the member, aka Grid/Row/Col/etc.
preventFullImport boolean no false Whether or not to throw when an import is encountered which would cause the entire module to be imported.
kebabCase boolean no false When set to true, runs ${member} through _.kebabCase.
