如何将Paddle与NextJS集成

Question

Paddle要求将这两个脚本插入到HTML中</body>之前：

<script src="https://cdn.paddle.com/paddle/paddle.js"></script>
<script type="text/javascript">
    Paddle.Setup({ vendor: 1234567 });
</script>

但是NextJS没有超文本标记语言文件，当我插入到返回函数中时，{ vendor: 1234567, debug: true }部件创建了一个'}' expected错误。

有人知道怎么解决这个问题吗？

您可以使用Next.Js提供的Script组件

https://nextjs.org/docs/basic-features/script

import Script from 'next/script'


<Script
  key="init-paddle"
  src="https://cdn.paddle.com/paddle/paddle.js"
  onLoad={() => {
    console.log('On paddle load')
    if (PADDLE_SANDBOX) {
      window.Paddle.Environment.set('sandbox')
    }
    window.Paddle.Setup({
      vendor: 12345,
      eventCallback: function (data) {
        // The data.event will specify the event type
        if (data.event === 'Checkout.Loaded') {
          console.log(data.eventData) // Data specifics on the event
        } else if (data.event === 'Checkout.Complete') {
          console.log(data.eventData) // Data specifics on the event
        } else if (data.event === 'Checkout.Close') {
          console.log(data.eventData) // Data specifics on the event
        }
      },
    })
  }}
/>

如果您使用的是typescript，并且您想要键入paddle集成，则可以使用：

(不是详尽的，但总比什么都没有好)

/// paddle.d.ts

export declare global {
  interface Customer {
    total: number
    total_tax: number
    currency: string
  }

  type PaddleEvent =
    | 'Checkout.Loaded'
    | 'Checkout.Close'
    | 'Checkout.Complete'
    | 'Checkout.User.Subscribed'
    | 'Checkout.Quantity.Change'
    | 'Checkout.Login'
    | 'Checkout.Logout'
    | 'Checkout.PaymentMethodSelected'
    | 'Checkout.Coupon.Add'
    | 'Checkout.Coupon.Submit'
    | 'Checkout.Coupon.Cancel'
    | 'Checkout.Coupon.Applied'
    | 'Checkout.Coupon.Remove'
    | 'Checkout.Error'
    | 'Checkout.Location.Submit'
    | 'Checkout.Language.Change'
    | 'Checkout.Vat.Add'
    | 'Checkout.Vat.Cancel'
    | 'Checkout.Vat.Submit'
    | 'Checkout.Vat.Applied'
    | 'Checkout.Vat.Remove'
    | 'Checkout.WireTransfer.Complete'
    | 'Checkout.PaymentComplete'
    | 'Checkout.PaymentMethodChange'
    | 'Checkout.WireTransfer.PaymentMethodChange'

  interface Window {
    Paddle: {
      Checkout: {
        open: (options: {
          product: string | number

      Environment: {

      }
      Setup: (options: {

                  length: number
                }
              }
              prices: {
                customer: Customer
              }
            }
            product: { id: number; name: string; quantity: number }
            user: { id: string; email: string; country: string }
          }
          checkoutData: {
            'paddlejs-version': '2.0.9'
            apple_pay_enabled: string
            display_mode: string
            guest_email: string
            is_popup: string

Answer 2

您需要将其设置为内部HTML

<script
        type="text/javascript"
        dangerouslySetInnerHTML={{
          __html: `
          Paddle.Setup({ vendor: 123456 });`,
        }}
      ></script>

不要从字面上理解文档。既然您使用的是React，那么包含任何内联JavaScript就没有意义了。Paddle.js只是客户端的，所以应该在根组件的useEffect回调中初始化它。

// pages/_document.js

import Document, { Html, Head, Main, NextScript } from 'next/document'

export default class MyDocument extends Document {
  static async getInitialProps(ctx) {
    const initialProps = await Document.getInitialProps(ctx)
    return { ...initialProps }
  }

  render() {
    return (
      <Html>
        <Head />
        <body>
          <Main />
          <NextScript />
          <script src="https://cdn.paddle.com/paddle/paddle.js" />
        </body>
      </Html>
    )
  }
}

// pages/_app.js

import { useEffect } from 'react'

function MyApp({ Component, pageProps }) {
  // Initialize Paddle
  useEffect(() => {
    Paddle.Setup({ vendor: 1234567 })
  }, [])

  return <Component {...pageProps} />
}
