# Configuration Options

All of Elixir's configuration is to support Webpack. Most of the custom changes you will make to Elixir will come through the `mergeConfig` method.

```javascript
const elixir = require("coldbox-elixir");

elixir.config.mergeConfig({});
```

The `mergeConfig` method will intelligently merge your new config with the existing Webpack config (thanks to [`webpack-merge`](https://github.com/survivejs/webpack-merge)).

There are a few additional config options on the Elixir object.

* `elixir.isProduction`
  * By default checks for the production flag from the terminal (`-p`)
* `elixir.rootPath`
  * The root of the project
* `elixir.config`
  * A configured instance of `ElixirConfig`
* `elixir.versioning`
  * Defaults to `elixir.isProduction`
