A starter boilerplate for creating NPM modules. Includes a few goodies to get you going like ES6 ready, ES5 compatibility and compilation, NPM Commands, and more!

Build Status devDependencies Status Coverage Status Known Vulnerabilities

Want to create your own NPM module but have no idea where to start? Hate how tedious it is recreating common project files? Would you rather watch paint dry than setting up yet ANOTHER ES6 compatible development environment? My friend, you've come to the right place. This repo takes care of all the initial fluff with none of the initial fuss.



This project runs using the latest stable version of NodeJS. To see what version of NodeJS is currently running on your system, run node -v in your terminal application.

Current Stable Version of NodeJS: Node Version

Update your systems version of NodeJS to match the version listed above before continuing.


Check out the Feature Details section of this README for additional information regarding individual feature default configurations and, if needed, how to go about reconfiguring individual features for your project needs. To see a complete list of the available NPM commands provided by default in this project and what they do, check out the NPM Commands section of this README.

  • ES6
  • Backwards compatibility for older versions of NodeJS
  • ES6 => ES5 production build ready
  • Testing
  • Linting
  • All the basic, but necessary, NPM commands for writing code from development to production ready! Plus, hooks for publishing to NPM!
  • A folder for working examples of your module other Devs can use as reference.
  • Tutorials for configuring/reconfiguring everything here along the way included inside! Plus, nice NPM commands for removing all excess tutorial code when you're ready to get rollin' like a pro.
  • Code Coverage
  • Continuos Integration


To get started with your new project, run the following commands:

cd <path/to/YOUR_PROJECT_NAME>
rm -rf .git
npm i

And that's it! Edit the package.json file with your own project information.

Feature Details


ES6 support provided via Babel using babel-preset-env. To edit or add to preset configurations, edit the .babelrc file found in the root folder of this project.


Mocha is included by default for writing and running tests. However, this repo is compatible with any testing framework you prefer! Just swap out Mocha as a project dependency with your favorite testing framework. Then, make any pre-configuration edits your testing framework may need. As a bonus, all tests can be written in ES6!


ESLint is included by default for code linting. To edit or add to preset configurations, edit the .eslintrc file. The .eslintignore file can be used to define files/folders where you wish linting rules to be ignores. Both the .eslintrc and .eslintignore files can be found in the root folder of this project. Preconfiguration for linting provided via AirBnB.


Code Coverage provided via Istanbul. As a plus, ES6 code support is included in coverage!


Continuos Integration, a.k.a CI, provided via TravisCI.

NPM Commands

npm run clean

Removes the ./lib/ directory.

npm run test

Runs tests.

npm run test:watch

Runs your tests, and then has them re-run on any file changes.

npm run lint

Runs linting against codebase.

npm run build

Compiles all development code in ./src to ES5. Then, the compiled code is output to the newly created lib directory found at the root of this project.

npm run coverage

Runs code coverage.

npm run coverage:open

Opens code coverage report in browser as a human readable report.

npm run prepare

Hooks for module publication to NPM. Runs all checks (tests/linting) first and then, if successful, publishes to NPM.

npm run test:examples

Runs tests against examples provided in ./examples/ directory.


To start development on your project, run the following command:

npm run dev

Your project is now running in development mode! Get to makin' some sexy code.


To run tests, run the following command:

npm run test

Your project tests status will output to the console. Pro-Tip: Run the following command to run tests that re-run on each file change!

npm run test:watch

Production Build

To create a production ready version of your project, run the following command:

npm run build

A production ready version of your project is now ready! You can find it in the lib folder located at the root of your project directory.

Deployment / Publication

To publish your project to NPM, run the following command:

npm run prepare

That's it! Your beautiful new project is now available as a brand new sweet NPM module! Grab a beer, you deserve it!

I created this project to end the constant boilerplate syndrome that comes with starting new projects and plan on keeping it constantly active.

This project is completely open to new contributers. Got a way to improve this project? Check out for details to add your own idea!
