Basic tools that we use in our projects for validation and formatting of CPF, CNPJ and EMAIL.
Just npm install anywhere-tools or yarn add anywhere-tools and then you can import it in your project.
import {CPF} from 'anywhere-tools'
CPF.validate('561.559.244-30') //returns true because it's a valid CPF
CPF.format('56155924430') //returns the formatted CPF
