formik 2.1.0

on Node.js Yarn

Minor Changes

• Add FieldHelpers object to the array returned by useField: #2124. This
  exposes three helper functions to allow you to imperatively change the
  field in question:

  1. setValue(value: any)
  2. setTouched(value: boolean)
  3. setError(value: string)

  Before

  const MyInput = (props) => {
   const formik = useFormikContext() 
   const [field, meta] = useField(props)
   const handleThing = () => {
      formik.setFieldValue(props.name, 'boop') 
   }
   // ...
  }

  After

  const MyInput = (props) => {
   const [field, meta, helpers] = useField(props)
   const handleThing = () => {
      helpers.setValue('boop') 
   }
   // ...
  }
