[BETA] Vue wrapper of Checkout.com Frames.

❗️BETA

This project is a minimal Vue wrapper of Checkout.com Frames. This version only supports the multiple iframes configuration.

🚀 Install

npm install frames-vue

🌐 Load the CDN script

Make sure that you load the Checkout.com CDN script before you mount any Frames components. You can add this, for example, in your index.html file.

<script src="https://cdn.checkout.com/js/framesv2.min.js"></script>

If you use server-side rendering, such as with Nuxt.js, you can add this inside your head object script array:

head: {
    script: [
      {
        src: "https://cdn.checkout.com/js/framesv2.min.js",
      },
    ],
  }

✨ Import the components

import { Frames, CardNumber, ExpiryDate, Cvv } from "frames-vue";

📖 Example Usage

To tokenize the payment card, this wrapper includes method submitCard(). In the below example, we call this when the "Pay Now" button is clicked.

<template>
  <div id="payment-form">
    <Frames
      :config="config"
      @ready="ready"
      @frameFocus="frameFocus"
      @cardTokenized="cardTokenized"
    />
    <CardNumber />
    <ExpiryDate />
    <Cvv />
    <button id="pay-button" @click="submitCard">Pay Now</button>
  </div>
</template>

<script>
import { Frames, CardNumber, ExpiryDate, Cvv } from "frames-vue";

export default {
  name: "App",
  components: {
    Frames,
    CardNumber,
    ExpiryDate,
    Cvv,
  },
  data() {
    return {
      config: {
        debug: true,
        publicKey: "pk_test_42e79f8e-28ad-4eed-8586-2764b1cc78e2",
        localization: {
          cardNumberPlaceholder: "Card number",
          expiryMonthPlaceholder: "MM",
          expiryYearPlaceholder: "YY",
          cvvPlaceholder: "CVV",
        },
        style: {
          base: {
            fontSize: "17px",
          },
        },
      },
    };
  },
  methods: {
    cardTokenized(e) { console.log(`Card token: ${e.token}`) },
    ready(e) { console.log("ready", e) },
    frameFocus(e) { console.log("frameFocus", e) },
    submitCard() { Frames.submitCard() },
  },
};
</script>

💳 Cardholder

For cases where you render the payment form at the same time as the billing and cardholder name input, you can use method setCardholder() to update Frames with this data before submitting.

<template>
...
<input
  id="cardholder-name"
  placeholder="Cardholder Name"
  v-model="config.cardholder.name"
/>
<input
  id="cardholder-phone"
  placeholder="Phone Number"
  v-model="config.cardholder.phone"
/>
<input
  id="cardholder-address-one"
  placeholder="Address 1"
  v-model="config.cardholder.billingAddress.addressLine1"
/>
...
<Frames :config="config" />
...
</template>

<script>
...
  data() {
    return {
      config: {
        cardholder: {
          name: "",
          billingAddress: {
            addressLine1: "",
            addressLine2: "",
            zip: "",
            city: "",
            state: "",
            country: "GB"
          },
          phone: "",
        },
        ...
      },
    };
  },
  methods: {
    submitCard() {
      Frames.setCardholder(this.config.cardholder);
      Frames.submitCard();
    },
  },
  ...
</script>
