React

The React version of Money Button is what we use throughout the main Money Button app and every other app we build. It is very similar to and is based on the pure javascript version of Money Button. In fact, it is simply a wrapper for the pure javascript version.

Because the React version of Money Button is simply a wrapper for the pure javascript version, this page has only introductory information to explain the difference between the two versions. For more detailed information about the API, please see the javascript documentation. Most of the documentation of the pure javascript version applies directly to the React version as well.

How to install the React component:

npm install @moneybutton/react-money-button

How to use it in your react project:

let MoneyButton = require('@moneybutton/react-money-button').default

How to use it to receive a specific amount at a specific address:

<MoneyButton
  to=[paymail, user ID, address, or script]
  amount=[amount]
  currency=[currency]
/>

The MoneyButton component can take a number of props:

prop	type	default value
to	string (paymail, user ID, address, or script)	null
amount	string	null
currency	string (USD, BSV, etc.)	'USD'
label	string	''
successMessage	string	'It's yours!'
outputs	array	[]
cryptoOperations	array	[]
clientIdentifier	string	null
buttonId	string	null
buttonData	string	null
type	string ('buy', 'tip')	'buy'
onPayment	function	null
onCryptoOperations	function	null
onError	function	null
onLoad	function	null
editable	boolean	false
disabled	boolean	false
devMode	boolean	false

outputs is a list of output objects. Each output object has these parameters:

name	type	required?
to	string	optional
paymail	string	optional
userId	string	optional
address	string	optional
script	string	optional
amount	string	required
currency	string (USD, BSV, etc.)	required

to, amount and currency work exactly as the top level attributes with the same name, except for the detail that all the outputs have to use the same currency. If there are 2 outputs using different currencies the button will fail before rendering.

Instead of using to argument you can specify which kind of output you are using with one of the attributes paymail, userId, address, or script.

cryptoOperations is a list of cryptographic operations, such as signatures, encryption and decryption, to be performed in the transaction or on off-chain data. See the crypto operations documentation.

Also, the onPayment function must look like this:

function myOnPaymentCallback (payment) {
    // ...
}

Where the payment is an object that looks like this:

name	type
id	string
buttonId	string
buttonData	string
status	string
txid	string
normalizedTxid	string
amount	string
currency	string
satoshis	string
outputs	array
cryptoOperations	array
userId	string
rawtx	string

Where in this case the outputs are slightly more sophisticated:

name	type
to	string
paymail	string
userId	string
script	string
address	string
amount	string
currency	string
satoshis	number
asset	string
assetOptions	object

to is optional. It can be a paymail, a user ID, an address, or a script.

onCryptoOperations function look like this:

function myOnCryptoOperationsCallback (cryptoOperations) {
    // ...
}

It receives a crypto operations array with replacements applied. Please see the crypto operations documentation.

onError function look like this:

function myOnErrorCallback (error) {
    // ...
}

It receives an object describing the error.

onLoad function look like this:

function myOnLoadCallback () {
    // ...
}

It is called when the button has loaded.

When devMode is set to true no transactions are made when you swipe the button. It's just to try the button.
