Request for Help with Integrating PayPal in Vue.js 3 Project

Hi everyone,

I've been struggling to find useful Vue.js 3 examples for integrating PayPal into real projects. It seems like everything available is only partially implemented. It would be fantastic if developers using Vue.js had the opportunity to seamlessly integrate PayPal with the help of good and comprehensive examples. This would undoubtedly benefit not only us but also PayPal.

I, along with many other developers, would greatly appreciate at least one example that we could use as a foundation for real projects.

Specifically, what I'm missing at this point is the ability to validate user input in the form as soon as the user clicks on a PayPal button. The payment window should only open if the entered data complies with all rules (e.g., Laravel Request Validation). Otherwise, an error message should be displayed (e.g., Laravel Request Validation Errors). If my approach is incorrect, I would appreciate a proper example that I can also use in practice.

Thank you for any code snippets you can provide!

Here is the structure I have so far. I've created a separate component for the PayPal buttons (with the idea of having a reusable component, possibly a wrong approach?).
The content of the file looks like this:

<template>
    <div>
        <div v-if="!paid" id="paypal-button-container"></div>
    </div>
</template>

<script>
import { loadScript } from '@paypal/paypal-js';
import axios from 'axios';

export default {
    name: 'PaypalButtons',
    emits: [
        'orderApproved',
    ],
    props: {
        item: {
            type: Object,
            required: true,
        },
        form: {
            type: Object,
            required: true,
        }
    },
    data() {
        return {
            paid: false,
            ppOptions: {
                'client-id': import.meta.env.VITE_PAYPAL_SANDBOX_CLIENT_ID,
                locale: import.meta.env.VITE_PAYPAL_LOCALE,
                currency: import.meta.env.VITE_PAYPAL_CURRENCY,
            },
            ppActions: null,
        };
    },
    methods: {
        createOrder(data, actions) {
            console.log('Creating order...');

            return axios.post(route('donation.create-order'), data)
                .then(res => {
                    // TODO: Call backend
                })
                .catch((error) => {
                    console.log("An error has occurred.")
                });
        },
        onApprove(data, actions) {
            console.log('Order approved...');

            return axios.post(route('donation.capture-order'), data)
                .then(res => {
                    this.paid = true;
                    this.$emit('orderApproved', res.data);

                    console.log('Order complete!');
                })
                .catch((error) => {
                    console.log("An error has occurred.")
                });
        },
        // Called when the button first renders.
        onInit(data, actions) {
            this.ppActions = actions;

            // Disable the payment buttons.
            this.ppActions.disable();
        },
        // Called when the button is clicked.
        onClick(data, actions) {
            console.log('Button is clicked.');

            // According to the PayPal documentation, the user input could be validated here. But what is the correct procedure here?

            let valid = false;

            // Enable or disable the button when it is checked or unchecked.
            if (valid) {
                this.ppActions.enable();
                return actions.resolve();
            } else {
                this.ppActions.disable();
                return actions.reject();
            }
        },
        // Handles any errors that occur while the payer submits the form.
        onError(error) {
            // Handle the error object
            console.error(error);
            // TODO: Informs the user about an error that has occurred. Output of a message in a pop-up window or similar.
        },
        // Buyer cancels a payment.
        onCancel(data) {
            console.info('Payment cancelled.');
            // TODO: Inform the user about the cancelled process. Output of a message in a pop-up window or similar.
        },
    },
    beforeMount() {
        loadScript(this.ppOptions)
            .then((paypal) => {
                paypal
                    .Buttons({
                        createOrder: this.createOrder,
                        onApprove: this.onApprove,
                        onInit: this.onInit,
                        onClick: this.onClick,
                        onError: this.onError,
                        onCancel: this.onCancel,
                        style: {
                            shape: 'pill',
                        },
                    })
                    .render('#paypal-button-container');
            })
            .catch((err) => {
                console.error("failed to load the PayPal JS SDK script", err);
            });
    },
};
</script>

This is how I plan to use the component:
<PaypalButtons :item="form.flower" :form="form" @order-approved="donationSuccessful"></PaypalButtons>

I would be very grateful for any contribution, no matter how small. And thank you already now on behalf of all Vuejs developers who are interested in the PayPal integration.

P.S.: I've already looked through the official PayPal documentation multiple times, but so far, it hasn't been of much help.

Upgrade to Vue 3

Move the codebase to use Vite and Vue 3 instead of Vue CLI(Webpack) and Vue 2
