Formik async email signup input

EmailInput.jsx

import React from 'react';
import debounce from 'utils/debounce';

class EmailInput extends React.Component {
  checkEmail = value => {
    // only check if the field passes Yup email validation first
    if (
      !this.props.form.errors[this.props.name].includes(
        'invalid' /* or whatever your error message is*/
      )
    ) {
      MyApi.checkEmail(value).then(
        success => {
          this.props.form.setFieldError(this.props.name, undefined);
          // if you need to show more info, like a checkbox:
          // this.props.form.setStatus({ email: true })
        },
        error =>
          this.props.form.setFieldError(
            this.props.name,
            transformErrorToEnglish(error)
          )
      );
    }
  };

  debouncedCheckEmail = debounce(this.checkEmail, 300); // 300ms debounce

  handleChange = e => {
    this.props.field.handleChange(e); // this will let Formik's default validation take place
    this.debouncedCheckEmail(e.target.value);
  };

  handleBlur = e => {
    this.props.field.handleBlur(e); // this will let Formik's default validation take place
    this.checkEmail(e.target.value);
  };

  render() {
    const { field, form, ...props /*  like placeholder */ } = this.props;
    return (
      <div>
        <input
          {...field}
          {...props}
          onChange={this.handleChange}
          onBlur={this.handleBlur}
        />
        {/** show errors */}
      </div>
    );
  }
}




export default EmailInput


// Usage

<Field name="email" component={EmailInput} placeholder="[email protected]" />

//  or

<Field name="email" render={props => <EmailInput {...props}  {...otherPropsYouMightNeed} />} />

FWIW I'm not sure this works on v1.1.1.
I get client side validation right after server-side validation and the errors are wiped out.
Similar to: jaredpalmer/formik#834

@cesarcf the field object has the onChange and onBlur methods, the form object has errors, touched, isValid, dirty etc. etc.

Can confirm this also does not work for me. Any error I set with setFieldError is cleared out on validation of another field.

@davetorbeck I had a similar issue with it being cleared out by my yup validation. Might not be the best solution but if you whack a setTimeout around it, it should run on the next loop and after the other validation has run, eg:

setTimeout(() => {
   form.setFieldError(this.props.name, EMAIL_EXISTS_ERROR_MESSAGE);
}, 0)

Hello!,
I think this lines is not correct:
this.props.field.handleChange (e);
this.props.field.handleBlur (e);

It should be like that, right?
this.props.form.handleChange (e);
this.props.form.handleBlur (e);

This example is so broken :( Did anyone ever get this to work and could you provide an example, please?
