# Getting started developing videojs-contrib-ads ## Building videojs-contrib-ads is designed to be built with `npm`. If you don't already have `npm`, you will need to install [Node.js](http://nodejs.org/) (which comes with npm). We recommend using [NVM](https://github.com/creationix/nvm) to manage your installed Node versions. Either way, the supported Node version is listed in the project's [.nvmrc file](https://github.com/videojs/videojs-contrib-ads/blob/master/.nvmrc). With NPM ready, you can download the ads plugin's build-time dependencies and then build the ads plugin. Open a terminal to the directory where you've cloned this repository, then: ```sh $ npm install $ npm run build ``` We will run a suite of unit tests and code formatting checks, then create a `dist/` directory. Inside you'll find the minified ads plugin file `videojs.ads.min.js`, the unminified `videojs.ads.js`, and the CSS `videojs.ads.css`. ## Linting Checks for errors or style issues. ```sh npm run lint ``` ## Testing Runs QUnit tests. ### Using command line ```sh npm run test ``` ### In browser Run `npm start` and a Chrome instance will launch with Karma's debug interface at `localhost:9876`, allowing you to debug tests. Also, a static server will run and allow you to look at examples at `localhost:9999`. ## What's Next Check out the [architecture overview](overview.md) to learn your way around the code.
