Expose Two (or More) Node.js Babel Classes In A Npm Scoped Package

I have two Node.js Babel classes in a public scoped package and want to expose them both. Classes in the public scoped NPM: Index.js export default class Index { constructor()

Solution 1:

After many hours researching I was able to find a workaround using vanilla code but keeping the Babel usage.

For the main JS file in your scoped NPM package e.g. index.js you must export all classes like:

importSecondClassfrom'./SecondClass';
importThirdClassfrom'./ThirdClass';

export {
    SecondClass,
    ThirdClass
};

And in your usage project you can import like:

import { SecondClass, ThirdClass } from'@my-scope/my-package';

newSecondClass();
newThirdClass();

The package.json from your scoped NPM package only need to expose the index.js like "main": "./dist/index.js".

Dependencies and versions:

• "babel-cli": "^6.26.0"
• "babel-preset-es2015": "^6.24.1"
• $ npm -v: 3.10.10
• $ node -v: v6.11.3

Solution 2:

The common approach is to create a file named index.js such that it reexports the different modules in the folder:

/src
    /foo.js
    /bar.js
    /index.js

// index.js
export * from './foo';
export * from 'bar';

This will allow you to import directly from the folder instead of an specific file.

import {foo, bar} from'./src';

Solution 3:

It is possible, try this:

Index.js

importSecondClassfrom'./SecondClass';

classIndex {
    constructor() {
        console.log("abc!");
    }
}
export { Index, SecondClass };

Usage

import { Index, SecondClass } from'@my-scope/my-package';

newIndex();
newSecondClass();
