Minor Changes

• 4148181 #​2794 Thanks @​jaredpalmer! - setValue can now optionally accept a function as a callback, exposing React.SetStateAction functionality. Previously, only the entire object was

v2.1.0

Compare Source

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') 
   }
   // ...
  }

v2.0.7

Compare Source

Improvements

• Massive perf boost over 2.0.6! We now save renders by comparing errors more efficiently in useFormik/Formik.
• FastField is now even faster. We fixed up our implementation of shouldComponentUpdate by refactoring the component away from using static contextType and back to using the connect() higher order component.

Bug fixes

• Fixed regression where dirty is wasn't re-evaluated after resetForm()

• Fixed regression where handleChange would explode when event.target didn't exist (e.g. event.currentTarget

• If there are validation errors while calling submitForm(), the promise will now rejects with errors (and of course abort the submit). Previously, it would abort the submit and resolve. The nuance is hard to describe so here is the difference.

  Before (2.0.6)

   submitForm() // imagine there are some Yup validation errors
    .then(() => console.log("abort submit, did not call onSubmit, and end up here"))
    .catch(() => console.log("abort submit, did not call onSubmit, but only because of a runtime error"));

  After (2.0.7)

   submitForm() // imagine there are some Yup validation errors
    .then(() => console.log("executed onSubmit"))
    .catch((err) => console.log("aborted submit attempt"));

Bugfix

• Change onSubmit's type signature to accept Promise<any>. This allows folks to return a promise that returns something (which is pretty common). Sorry about that folks.

v2.0.5

Compare Source

Bugfixes

• Changed onSubmit behavior to mimic v1 if the function is synchronous. This means fixes a bug where isSubmitting was never toggled. To summarize: If onSubmit is async, then Formik will automatically set isSubmitting to false on your behalf once the submission is completed. This means you do NOT need to call formikBag.setSubmitting(false) manually in v2. HOWEVER, if your onSubmit function is synchronous (e.g. v1), then you need to still call setSubmitting(false) on your own. (#​1987)
• Fix checkbox bug with null value (#​2027)
• Update validateFormWithLowPriority with to use fresh values (#​2025)
