javascript - Server and client side validators - library -

what best library validate objects on server , client side ? i'm searching simpler - 1 simple config file , in both sides like:

var is_valid = validation(object, validationrule);

but should have many validation options, example:

obj: a, b, c, d; = something; b, c - required; d - not needed/hidden   d = something: c - required; b - optional/has value - not needed/hidden 

on client side use aurelia framework. has validation plugin, have no idea how use on server. means that, use same functionvalidation , configvalidation on server, , client;

or perhaps - there plugin work aurelia-validation ?

on server use node.js backend;

i looking - great didn't have duplicate our work.

joi looks excellent server side validation (it powers walmart , paypal , fast) - it's kinda possible use on client.

then there's validate.js looks might both.

i opened reddit question since can't find info on this.
