Formik Effect

Declarative Formik component for side-effects

``npm install formik-effect --save`

Note: this has peer dependencies of prop-types, react, and formik (obvs)

`Basic Usage`

Import the component and put it inside any Formik form. It renders null! Pass it an onChange() function and it will be called whenever your Formik form updates.

`js import React from 'react' import { Formik, Field, Form } from 'formik' import { Effect } from 'formik-effect'

export const Signup = () =>


    My Cool Form with a SideEffect

          onSubmit={values => console.log(values)}
      initialValues={{ firstName: '', lastName: '', email: '' }}
      render={props =>
        
           {
               // do whatevs
               // FYI if you alter state it will cause another render
            }} 
          />
          
          
          
          
         
        }
    />
