Better form validation and value management for React. Provides minimal wiring while also allowing for complete input flexibility.

Built on yup and react-input-message.


npm i -S react-formal yup

(don't like the yup but like how the form works? Try: topeka)


For more complete api documentations, live examples, and getting started guide check out the documentation site.

react-formal uses a yup schema to update and validate form values. It treats the form like an input (representing an object) with a value and onChange. The form can be controlled or uncontrolled as well, just like a normal React input.

var yup = require('yup')
  , Form = require('react-formal')

var modelSchema = yup.object({
        name: yup.object({
            first: yup.string().required('Name is required'),
            last: yup.string().required('Name is required')
            .max(new Date(), 'You can be born in the future!')

// a component
render() {
    return (
            onChange={model => this.setState({ model })}
                <legend>Personal Details</legend>

                <Form.Field name='name.first'/>
                <Form.Message for='name.first'/>

                <Form.Field name='name.last'/>
                <Form.Message for='name.last'/>

                <Form.Field name='dateOfBirth'/>
                <Form.Message for='dateOfBirth'/>
            <Form.Submit type='submit'>Submit</Form.Submit>
