vue-select/src/utility/sortAndStringify.js

Everything you wish the HTML <select> element could do, wrapped up into a lightweight, extensible Vue component.

/**
 * @param sortable {object}
 * @return {string}
 */
function sortAndStringify(sortable) {
  const ordered = {}

  Object.keys(sortable)
    .sort()
    .forEach((key) => {
      ordered[key] = sortable[key]
    })

  return JSON.stringify(ordered)
}

export default sortAndStringify
