Validator on js, recommend?

Question

JavaScript

We need a js validator, fresh and light.
Functionality:
1. The page is loading, all fields are standard.
2. The user starts entering data and at this time the validator must add the valid or invalid class according to the condition and data.
3. Ability to validate on blur.
4. Easy to integrate. In my case it is Vue.js.
Thank you.

https://github.com/vuejs/vue-validator though you need to think of something right away so that you don’t rewrite the highlight and text for each input
