React components to integrate Braintree hosted fields

A few small React components to make integrating Braintree's Hosted Fields easier.

Introduction

import { Braintree, HostedField } from 'react-braintree-fields';
class MySillyCheckoutForm extends React.PureComponent {

    function onSubmit() {
        // could also obtain a reference to the Braintree wrapper element and call `.tokenize()`
       this.getToken({ cardholderName: 'My Order Name' }).then((payload) => {
         console.log("nonce=" , payload.nonce)
       })
    }

    onCardTypeChange() {
        this.setState({ card: (1 === cards.length) ? cards[0].type : '' });
    }

    function onFocus(event) {
        console.log("number is focused", event);
    }

    onError(err) {
       console.warn(err);
       this.ccNum.focus(); // focus number field
    }

    render() {
        return (
            <Braintree
                authorization='sandbox_g42y39zw_348pk9cgf3bgyw2b'
                onError={this.handleError}
                onCardTypeChange={this.onCardTypeChange}
                getTokenRef={ref => (this.getToken = ref)}
                styles={{
                    'input': {
                        'font-size': '14px',
                        'font-family': 'helvetica, tahoma, calibri, sans-serif',
                        'color': '#3a3a3a'
                    },
                    ':focus': {
                        'color': 'black'
                    }
                }}
            >
                <div className="fields">
                    <HostedField type="number" onFocus={onFocus} ref={ccNum => (this.ccNum = ccNum)} />
                    <HostedField type="expirationDate" />
                    <HostedField type="cvv" />
                </div>
                <button onClick={onSubmit}>Submit</button>
            </Braintree>
        );
    }
}

See demo site for a working example. It renders demo.jsx

Braintree Component

Props:

• authorization: Required, either a tokenization key or a client token
• styles: Object containing valid field styles
• onError: Function that will be called if an Braintree error is encountered.
• getTokenRef: A function that will be called once Braintree the API is initialized. It will be called with a function that can be used to initiate tokenization.
  • The tokenization function will return a Promise which will be either resolved or rejected. If resolved, the promise payload will contain an object with the nonce and other data from Braintree.

HostedField Component

Props:

• type: Required, one of:
  • 'number', 'expirationDate', 'expirationMonth', 'expirationYear', 'cvv', 'postalCode'
• onBlur
• onFocus
• onEmpty
• onNotEmpty
• onValidityChange
• onCardTypeChange - accepted on any field, but will only be called by type="number"
• placeholder - A string to that will be displayed in the input while it's empty
• formatInput
• maxlength,
• minlength
• select

See the Braintree api docs for more details

Fields also have "focus" and "clear" methods. These may be called by obtaining a reference to the field.
