The theme can be accessed via our building block component props. E.g a Box's backgroundColor prop will map to the colours object in our theme. Similarly, a Text component's fontSizes property will map to the fontSizes object, etc.

Custom themes

As of version 3.0, themes can be overriden at the NDSProvider level. This allows changing all definitions of a property at once.

For example, if you were working in one of our legacy Operational Solution modules and wanted the "medium" font size used in all components to be 14px instead of 16px:

import { NDSProvider } from "@nulogy/components"
<NDSProvider theme={fontSizes: {medium: "14px"}}>
// app
