Install

The easiest way to use nod is through the Yeoman Generator.

$ npm install -g yo generator-nod
$ yo nod

If you don't want to use the generator, you can also download or git clone this repo

$ git clone https://github.com/diegohaz/nod my-module
$ cd my-module
$ rm -rf .git
$ npm install # or yarn

Just make sure to edit package.json, README.md and LICENSE files accordingly with your module's info.

Commands

$ npm test # run tests with Jest
$ npm run coverage # run tests with coverage and open it on browser
$ npm run lint # lint code
$ npm run docs # generate docs
$ npm run build # generate docs and transpile code

Publish

$ npm release
$ npm publish

It'll automatically run test, lint, docs, build, generate CHANGELOG.md, and push commits and tags to the remote repository.
