const handler = {
  // if path is localhost:3000/user
  user: (data, cb) => {
    const {
      method
    } = data;
    const allowedMethods = ["post", "get"];

    if (allowedMethods.indexOf(method) !== -1) {
      handler._count[method](data, cb);
    } else {
      cb(
        405, {
          err: "unknown method"
        },
        "json"

  _count: {
    // if method is post
    post: (data, cb) => {
      // do something
    },
    get: (data, cb) => {
      // do something more
    }
