## Validator For Express

* Install the package `npm i mevn-validator`

* The Validator must be instatiated with the `new KeyWord`

```javascript

   const Validator = require('mevn-validator')

   // Create a validator instance

   let validate = new Validator(fields: Object, rules: Object)

   validate.validate()

   .then(valid => {

       // do something when the validation passes

   })

   .catch(messages => {

       // You would probably need to send this to the user

       // the messages contains the error messages

   })

   // OR like a cool kid 😎

   new Validator(fields: Object, rules: Object).then(....).catch(...).finally(...)

```
