a redux-form Field component that supports a normalizeOnBlur property

npm install --save redux-form-normalize-on-blur

const { Field } = require('redux-form-normalize-on-blur')

or

const { Field } = require('redux-form-normalize-on-blur/immutable')

The following field will trim its text when it loses focus:

<Field
  name="name"
  normalizeOnBlur={(value) => value && value.trim()}
  component={YourInputComponent}
/>

Has the same API as redux-form's Field, but it accepts an additional normalizeOnBlur property:

Function that takes the current value and returns the normalized value. NOTE: this happens before parse or normalize!
