Sanity: Let me customize the webpack config

[miracle2k]

Is your feature request related to a problem? Please describe.

When I define a preview component for a type, it is often useful to re-use components that will later be used to render a type. If those components are written in typescript, it is problematic, because I cannot just import them directly.

Describe the solution you'd like

Allow me to customize the webpack config used by the sanity dev server and build.

Describe alternatives you've considered

Support a more extensive feature set out of the box, similar to create-react-app.

I agree we should provide the ability to use a custom webpack config. In the meantime you should be able to use TypeScript for your custom components by adding a .babelrc to your sanity project and use the @babel/typescript preset.

@bjoerge any update on this?

Is there some sort of workaround for example to allow custom webpack loaders?
