get variant list from CVA definition

Hey all I'm using class-variance-authority to define component styles. Wondering if there's a way to reuse the defined variant keys. E.g.

import * as React from "react"
import { VariantProps, cva } from "class-variance-authority"
 
import { cn } from "@/lib/utils"
 
const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors",
  {
    variants: {
      variant: {
        default:
          "bg-slate-900 text-white hover:bg-slate-700 dark:bg-slate-50 dark:text-slate-900",
        destructive:
          "bg-red-500 text-white hover:bg-red-600 dark:hover:bg-red-600",
        outline:
          "bg-transparent border border-slate-200 hover:bg-slate-100 dark:border-slate-700 dark:text-slate-100",
        subtle:
          "bg-slate-100 text-slate-900 hover:bg-slate-200 dark:bg-slate-700 dark:text-slate-100",
        ghost:
          "bg-transparent hover:bg-slate-100 dark:hover:bg-slate-800 dark:text-slate-100 dark:hover:text-slate-100 data-[state=open]:bg-transparent dark:data-[state=open]:bg-transparent",
        link: "bg-transparent dark:bg-transparent underline-offset-4 hover:underline text-slate-900 dark:text-slate-100 hover:bg-transparent dark:hover:bg-transparent",
      },
      size: {
        default: "h-10 py-2 px-4",
        sm: "h-9 px-2 rounded-md",
        lg: "h-11 px-8 rounded-md",
      },
    },
    defaultVariants: {
      variant: "default",
      size: "default",
    },
  }
)

import * as React from "react"
import { VariantProps, cva } from "class-variance-authority"
 
import { cn } from "@/lib/utils"
 
const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors",
  {
    variants: {
      variant: {
        default:
          "bg-slate-900 text-white hover:bg-slate-700 dark:bg-slate-50 dark:text-slate-900",
        destructive:
          "bg-red-500 text-white hover:bg-red-600 dark:hover:bg-red-600",
        outline:
          "bg-transparent border border-slate-200 hover:bg-slate-100 dark:border-slate-700 dark:text-slate-100",
        subtle:
          "bg-slate-100 text-slate-900 hover:bg-slate-200 dark:bg-slate-700 dark:text-slate-100",
        ghost:
          "bg-transparent hover:bg-slate-100 dark:hover:bg-slate-800 dark:text-slate-100 dark:hover:text-slate-100 data-[state=open]:bg-transparent dark:data-[state=open]:bg-transparent",
        link: "bg-transparent dark:bg-transparent underline-offset-4 hover:underline text-slate-900 dark:text-slate-100 hover:bg-transparent dark:hover:bg-transparent",
      },
      size: {
        default: "h-10 py-2 px-4",
        sm: "h-9 px-2 rounded-md",
        lg: "h-11 px-8 rounded-md",
      },
    },
    defaultVariants: {
      variant: "default",
      size: "default",
    },
  }
)

I'd like to get the variant keys as an array of strings.

You can define an object with your variants, and then pass it to cva:

const yourVariants = {
  default: ...,
  destructive: ...,
  ...
}

const btnVariants = cva('base', {
  variants: {
    variant: yourVariants,
    ...
  },
  ...
})

const variantKeys = Object.keys(yourVariants)

const yourVariants = {
  default: ...,
  destructive: ...,
  ...
}

const btnVariants = cva('base', {
  variants: {
    variant: yourVariants,
    ...
  },
  ...
})

const variantKeys = Object.keys(yourVariants)

@Daryl I'm sure I tried this and got type errors! Works perfectly now, thank you :)
