Create npm packages with no build configuration.

Table of Content


Creating npm packages is awesome but setting up the build tools every time is exhausting and not productive.


With Create Package you don't need to configure Babel, Rollup, Flow or TypeScript.
They are preconfigured and hidden behind a single dependency.

Just create a project and start coding. You don't have to worry how to set up the build tools and update them.

Why Use This?

If you want to create a npm package but don't want to configure build tools you should use Create Package. You will get everything you need to create modern npm packages:

  • Latest JavaScript features with Babel
  • Optional TypeScript and Flow support
  • Node and Web packages
  • Snapshot testing with Jest
  • Assistant while developing with ESLint and TSLint

Getting Started


Install Create Package once globally:

npm install -g create-package

Create Package supports Node >= 4 and npm >= 3. You can use n or nvm to easily switch Node versions between different projects.


To create a new package run:

create-package my-awesome-package
cd my-awesome-package

This will create a new directory called my-awesome-package inside the current working directory.
Inside this directory, we will create a simple initial project structure with our only dependency package-scripts installed.

├── .gitignore
├── node_modules
├── package.json
└── src
    ├── index.js
    └── index.test.js

Once the installation is done, you can run some commands inside the project folder:

npm test --watch or yarn test --watch

This will run the Jest test runner in watch mode.

npm run build or yarn build

This will compile all your files and creates a UMD bundle if you want to support the web.

What we do?

We check which environments you want to support with browserslist and the engines.node field in you package.json.

  • Node Environment — We compile all your JS, Flow and TypeScript files to the lowest Node version you want to support to the lib directory.

  • Web Environment — In addition to the lib folder we also compile your files to an es directory which is the same but with ES modules instead of CommonJS modules for Rollup and WebPack. We also create a UMD bundle which you can use for script tags or

npm run check or yarn run check

This will run ESLint to check for common errors. We don't want to stay in your way while hacking. Please feel free to open an issue if a linting rule annoys you.

If you have TypeScript or Flow installed we also check for type errors with this command.


  • One Dependency — Nice developer experience and easy way to update your build tools.

  • No configuration needed — We want you to focus on creating awesome packages so we will handle the configuration for you.

  • Latest JS Features — You can use the latest JS features and we will compile them down to support older environments.

  • Types with Flow and TS — Easily add support for TypeScript and Flow.
