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')
}),
dateOfBirth: yup.date()
.max(new Date(), 'You can be born in the future!')
})
// ...in a component
render() {
return (
<Form
schema={modelSchema}
value={this.state.model}
onChange={model => this.setState({ model })}
>
<fieldset>
<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'/>
</fieldset>
<Form.Submit type='submit'>Submit</Form.Submit>
</Form>
)
}
