Adonisjs Admin Panel Generator is a package that helps you quickly scaffold your typical CRUD admin interfaces. It generates the admin panel code based on the existing (migrated) table in the database

export function truncate(str, num = 50) {
  if (str.length > num) {
    return str.slice(0, num) + "...";
  } else {
    return str;
  }
}
