CLI Argument Parser (utils/args.ts)

Parses and type-converts raw CLI string arguments into typed values (boolean, number, string combos) for Tailwind CLI commands using mri.

import parse from 'mri'

// Definition of the arguments for a command in the CLI.
export type Arg = {
  [key: `--${string}`]: {
    type: keyof Types
    description: string
    alias?: `-${string}`
    default?: Types[keyof Types]
  }
}

// Each argument will have a type and we want to convert the incoming raw string
// based value to the correct type. We can't use pure TypeScript types because
// these don't exist at runtime. Instead, we define a string-based type that
// maps to a TypeScript type.
type Types = {
  boolean: boolean
  number: number | null
  string: string | null
  'boolean | string': boolean | string | null
