object-replace-mustache/src/is-template-string.ts

replace placeholders of an object with a view like you would use mustache.render for strings

import { delimitersMustache, regexForDelimiters } from './utils'

export type IsTemplateStringOptions = {
  delimiters: [string, string]
}

export const isTemplateString = (
  str: any,
  options?: IsTemplateStringOptions,
): str is string => {
  if (!str || typeof str !== 'string') {
    return false
  }

  const regex = regexForDelimiters(options?.delimiters ?? delimitersMustache)

  return regex.test(str)
}
