## Current Behavior
Some webpack output options, like `filename` are overwritten when using
the `NxWebpackPlugin`, e.g.
```ts
module.exports = {
output: {
path: join(__dirname, '../../dist/apps/my-app'),
// this has no affect:
filename: ({ runtime }) =>
migrationEntryPoints.some(({ entryName }) => entryName === runtime)
? 'migrations/[name].js'
: '[name].js',
},
plugins: [
new NxWebpackPlugin({ ... }),
]
};
```
## Expected Behavior
The `NxWebpackPlugin` should preserve base config where it makes sense.
I think this is the intended behaviour, but required some extra
parentheses to behave correctly.
