Typescript: missing interface for colorScales parameter of generateAdaptiveTheme function

[Federico Ciardi]

Description

colorScales parameter type of generateAdaptiveTheme should became a separated interface to simplify the use of the function when working in a typescript project.

function generateAdaptiveTheme({ 
    colorScales, 
    ...
  }: {
    colorScales: {
      name: string,
      colorKeys: string[],
      colorspace: InterpolationColorspace,
      ratios: number[] | { [key: string]: number },
      smooth?: boolean
    }[],
    ...
  }): AdaptiveTheme | never;

Why do you need this feature?

example of the advantage of using a separate interface:

const uiRatios = [1, 1.5, 2, 2.5, 3, 4.5, 7, 11, 16];

const redScale: ColorScales = {
   name: 'red',
   ratios: uiRatios,
   colorKeys:  [],
   colorspace: 'HEX'

}

const blueScale: ColorScales = {
   name: 'blue',
   ratios: uiRatios,
   colorKeys:  [],
   colorspace: 'HEX'
}

generateAdaptiveTheme({
   colorScales: [redScale, blueScale],
   baseScale: "red"
})
