### default defaults
```
{
  env: {
     production: {
       uglify: true,
       defineProduction: true,
       run: false,
       compile: true,
       useSourceMaps: false,
       sourceMapTool: 'hidden',
     },
     development: {
       noEmitErrors: true,
     },
  }
}
```

### adding your own defaults
this would make it so if `fusebox` [flag](#flags) are true, it would add the fusebox property to any app that has passed [filters](#filters) and is being built.
```js
fliphub.addDefaults({
  flags: {
    // this can also be a objects,
    // or an array of strings
    // or a string
    names: [{flag: 'fusebox', type: 'bool', default: false}],
    cb: ({fusebox}) => {
      return {fusebox}
    },
  },
})
```
