## Custom builds

The folder `dist` contains bundled versions of vis.js for direct use in the browser. These bundles contain all the visualizations and include external dependencies such as *hammer.js* and *moment.js*.
The source code of vis.js consists of commonjs modules, which makes it possible to create custom bundles using tools like [Browserify](http://browserify.org/) or [Webpack](http://webpack.github.io/). This can be bundling just one visualization like the Timeline, or bundling vis.js as part of your own browserified web application.

#### Prerequisites
### Prerequisites
Before you can do a build:
- Install node.js and npm on your system: https://nodejs.org/
- Install *node.js* and *npm* on your system: https://nodejs.org/
- Install the following modules using npm: `browserify`, `babelify`, and `uglify-js`:
```
$ [sudo] npm install -g browserify babelify uglify-js
```

Then create a custom bundle using browserify, like:

This will generate a custom bundle *vis-custom.js*, which exposes the namespace `vis` containing only `DataSet` and `Timeline`. The generated bundle can be minified using uglifyjs:
