# Malga Checkout - React

A simple, fast and customizable way of integrating with Malga, with no need to stop using your favorite front-end framework.

## Introduction

[Here is a demonstration](https://github.com/plughacker/demo-malga-checkout-react) of a React application integrated with Malga Checkout.

## Get Started

To start it, simply install the dependency on your project

```bash
yarn add @malga-checkout/react
# or
npm install --save @malga-checkout/react
```

Import Malga Checkout in one of your components

```js
import MalgaCheckout from '@malga-checkout/react'
```

And use it like this. Its most basic way, with no customization, needs very few configurations.

```tsx
<MalgaCheckout
  publicKey="<YOUR_PUBLIC_KEY>"
  clientId="<YOUR_CLIENT_ID>"
  merchantId="<YOUR_MERCHANT_ID"
  statementDescriptor="#1 Demonstration Malga Checkout"
  amount={100}
  onPaymentSuccess={({ detail }) => handlePaymentSuccess(detail.data)}
  onPaymentFailed={({ detail }) => handlePaymentFailed(detail.error)}
/>
```

## UI Customization

For the checkout to be completely transparent and extensible, we provide some forms of customization so that it has the “face” of your company.

### Theme

For theme customization (color pallet, spacing and typography) you may overwrite the variable values on your main file of CSS of application (usually the index.css). The variables we currently use are the ones below:

```css
:root {
  /* Colors */
  --malga-checkout-color-brand-accent-light: #4ebff1;
  --malga-checkout-color-brand-accent-normal: #0055a2;
  --malga-checkout-color-brand-light: #0091ea;
  --malga-checkout-color-brand-normal: #5c7ec0;
  --malga-checkout-color-brand-middle: #344383;
  --malga-checkout-color-brand-dark: #141b4d;
  --malga-checkout-color-grey-light: #aaafc5;
  --malga-checkout-color-grey-normal: #8b90a7;
  --malga-checkout-color-grey-middle: #5e6277;
  --malga-checkout-color-grey-dark: #3f4252;
  --malga-checkout-color-accent-light: #ffffff;
  --malga-checkout-color-accent-normal: #eef2f6;
  --malga-checkout-color-accent-middle: #aebfd0;
  --malga-checkout-color-warning-light: #fff8e1;
  --malga-checkout-color-warning-normal: #fac30e;
  --malga-checkout-color-warning-middle: #ffa200;
  --malga-checkout-color-success: #32c000;

  /* Typography */
  --malga-checkout-typography-family: 'Lato', sans-serif;

  /* Spacings */
  --malga-checkout-spacing-xxs: 4px;
  --malga-checkout-spacing-xs: 8px;
  --malga-checkout-spacing-sm: 16px;
  --malga-checkout-spacing-default: 24px;
  --malga-checkout-spacing-md: 32px;
  --malga-checkout-spacing-lg: 48px;
  --malga-checkout-spacing-xlg: 64px;
  --malga-checkout-spacing-xxlg: 96px;

  /* Sizes */
  --malga-checkout-size-min-width: 250px;

  /* Border Radius */
  --malga-checkout-border-radius-default: 4px;

  /* Transitions Time */
  --malga-checkout-transition-slow: 0.3s;
  --malga-checkout-transition-default: 0.5s;
}
```

### Components

For customization focused directly on visual components that are part of the Malga Checkout, we provide the prop customFormStyleClasses which accepts an object with a series of properties that may be attributed CSS classes, that are created on your main file of CSS of application (usually the index.css). Below there is a list of properties the customFormStyleClasses supports:

```js
const defaultCustomStyles = {
  formContainer: '<YOUR_CUSTOM_CLASS>',
  formContent: '<YOUR_CUSTOM_CLASS>',
  creditCardFieldContainer: '<YOUR_CUSTOM_CLASS>',
  creditCardFieldLabelContainer: '<YOUR_CUSTOM_CLASS>',
  creditCardFieldInputContainer: '<YOUR_CUSTOM_CLASS>',
  expirationDateFieldContainer: '<YOUR_CUSTOM_CLASS>',
  expirationDateFieldLabelContainer: '<YOUR_CUSTOM_CLASS>',
  expirationDateFieldInputContainer: '<YOUR_CUSTOM_CLASS>',
  cvvFieldContainer: '<YOUR_CUSTOM_CLASS>',
  cvvFieldLabelContainer: '<YOUR_CUSTOM_CLASS>',
  cvvFieldInputContainer: '<YOUR_CUSTOM_CLASS>',
  nameFieldContainer: '<YOUR_CUSTOM_CLASS>',
  nameFieldLabelContainer: '<YOUR_CUSTOM_CLASS>',
  nameFieldInputContainer: '<YOUR_CUSTOM_CLASS>',
  installmentsFieldContainer: '<YOUR_CUSTOM_CLASS>',
  installmentsFieldLabelContainer: '<YOUR_CUSTOM_CLASS>',
  installmentsFieldSelectContainer: '<YOUR_CUSTOM_CLASS>',
  submitButton: '<YOUR_CUSTOM_CLASS>',
}
```
