paypal-basket

A simple basket & product manager for the PayPal-node SDK.

This module will assist you in managing your products and baskets, in order to craft the Paypal payment request (JSON doc).
Ultimatively it can also request the actual PayPal payment details for you.

Features:

Easy product & basket management
ES8, ES6, ES5 support
Async/Await, Promises & Callbacks
Tests

Variants:

Due to migration of the package over the last years, it comes in 3 variants.
All of them share the same code, version, receive all future updates, and
you won't have to update your package.json:

Adding products to a basket

/* Synchronous */
demoBasket.add(demoProduct)
demoBasket.add(demoProduct, 10)

/* Async/Await */
await demoBasket.add(demoProduct)
await demoBasket.add(demoProduct, 10)

/* Promise */
demoBasket.add(demoProduct)
  .then(() => console.log('Product has been added!'))
  .catch(err => console.log(err))

/* Promise batch */
demoBasket.add(demoProduct)
  .then(demoBasket.add(demoProduct))
  .then(demoBasket.add(demoProduct))
  .then(demoBasket.add(demoProduct))

/* Callback */
demoBasket.add(demoProduct, err => {
  if (err) { return console.log(err) }
  console.log('Product has been added!')
})

Deleting products from a basket

Selling a basket (crafting manifest / payment request)

Available options:

		Required
currency	ISO 4217 currency code (eg. USD, EUR, GBP,...)	No
description	Describe the payment (eg. Mike's payment)	No
norequest	Enable/Disable payment-request processing by paypal-basket.	No
	If this option is set to `true`, paypal-basket will not perform the actual payment-request. In addition, the `.payment` property of the manifest won't be available. If this option is set to `false`, paypal-basket will perform the actual payment-request, and the `.payment` property of the manifest will be available.

Auto payment-request processing:

/* Async/Await */
const manifest = await demoBasket.sell({ 'currency': 'USD' })
// Payment request has been performed and you can access
// the data (links, timestamp, etc) by using manifest.payment
console.log("Payment ID: " + manifest.payment.id)
console.log("Payment created: " + manifest.payment.create_time)
console.log("Payment URL: " + manifest.payment.links[1].href)

/* Promise */
demoBasket.sell({ 'currency': 'USD' })
  .then(manifest => {
    // Payment request has been performed and you can access
    // the data (links, timestamp, etc) by using manifest.payment
    console.log("Payment ID: " + manifest.payment.id)
    console.log("Payment created: " + manifest.payment.create_time)
    console.log("Payment URL: " + manifest.payment.links[1].href)
  })
  .catch(err => console.log(err))

/* Callback */
demoBasket.sell({ 'currency': 'USD' }, (err, manifest) => {
  if (err) { return console.log(err) }
  // Payment request has been performed and you can access
  // the data (links, timestamp, etc) by using manifest.payment
  console.log("Payment ID: " + manifest.payment.id)
  console.log("Payment created: " + manifest.payment.create_time)
  console.log("Payment URL: " + manifest.payment.links[1].href)
})

Manual payment-request processing:

const paypal = require('paypal-rest-sdk')

/* Async/Await */
const manifest = await demoBasket.sell({ 'currency': 'USD', 'norequest': true })
// Payment request has not been performed and you can use
// the manifest to perform it yourself
const payment = await paypal.payment.create(manifest)
console.log("Payment ID: " + payment.id)
console.log("Payment created: " + payment.create_time)
console.log("Payment URL: " + payment.links[1].href)

/* Promise */
demoBasket.sell({ 'currency': 'USD', 'norequest': true })
  .then(manifest => {
    // Payment request has not been performed and you can use
    // the manifest to perform it yourself
    paypal.payment.create(manifest, (errPP, payment) => {
      if (errPP){ console.log(errPP) }
      console.log("Payment ID: " + payment.id)
      console.log("Payment created: " + payment.create_time)
      console.log("Payment URL: " + payment.links[1].href)
    })
  })
  .catch(err => console.log(err))

/* Callback */
demoBasket.sell({ currency: 'USD', 'norequest': true }, (err, manifest) => {
  if (err) { return console.log(err) }
  // Payment request has not been performed and you can use
  // the manifest to perform it yourself
  paypal.payment.create(manifest, (errPP, payment) => {
    if (errPP) { console.log(errPP) }
    console.log("Payment ID: " + payment.id)
    console.log("Payment created: " + payment.create_time)
    console.log("Payment URL: " + payment.links[1].href)
  })
})

Payment request-data:

Examples

Example 1 (Music Store)

In this example paypal-basket will craft the manifest and request the actual payment by using the internal Paypal-SDK.

const { Paypal, Basket, Product } = require('@notixbit/paypal-basket')

/* Configure paypal sdk */
Paypal.configure({
  mode: 'sandbox',
  client_id: '',
  client_secret: ''
})

/* A JSON collection of music albums */
const albums = [
  {
    "sku": "davidguettalisten",
    "name": "David Guetta - Listen",
    "price": "5.00"
  },
  {
    "sku": "michaeljacksonworld",
    "name": "Michael Jackson - World",
    "price": "10.00"
  },
  {
    "sku": "simplyredthrillme",
    "name": "Simply Red - Thrill me",
    "price": "10.00"
  }
]

/* 
  A collection of music products
  to contain the actual album products
*/
const products = {}

/* 
  Create products from albums 
  and push to collection
*/
for(const index in albums) {
  const album = albums[index]
  products[album.sku] = new Product(album)
}

/* 
  At this point you can access a product like:

  products['michaeljacksonworld']
  products['davidguettalisten']
*/

/* Create a basket (eg. for a customer) */
const sessionxyzBasket = new Basket({
  label: 'Basket of session xyz',
  urls: {
    return_url: 'http://return.url',
    cancel_url: 'http://cancel.url'
  }
})

/* 
  Now let the customer add/del 
  some products to/from their basket.
  Presumably via website
*/
sessionxyzBasket.add(products['davidguettalisten'])
sessionxyzBasket.add(products['michaeljacksonworld'])
sessionxyzBasket.add(products['simplyredthrillme'])
sessionxyzBasket.del(products['davidguettalisten'])

/* Print current total */
console.log('Current total is: $' + sessionxyzBasket.total)

/*
  Now sell the basket (generate manifest)
  and request actual payment details
*/
try {
  const manifest = await sessionxyzBasket.sell({ 'currency': 'USD' })
  console.log("Payment Response:")
  console.log(manifest.payment)
} catch (err) {
  console.log(err)
}

Result:

Example 2 (Manual payment-request)

In this example paypal-basket will craft the payment manifest, but it won't perform the actual payment request.
Just perform the request yourself.

Make sure norequest is true.

const paypal = require('paypal-rest-sdk')
const { Basket, Product } = require('@notixbit/paypal-basket')

/* Configure external paypal sdk */
paypal.configure({
  mode: 'sandbox',
  client_id: '',
  client_secret: ''
})

/* Some sample products */
const demoProduct1 = new Product({
  sku: 'demoproduct1',
  name: 'Demo Product 1',
  price: 15.00
})

const demoProduct2 = new Product({
  sku: 'demoproduct2',
  name: 'Demo Product 2',
  price: 6.53
})

/* Create a basket (eg. for a customer) */
const demoBasket = new Basket({
  label: 'Demo Basket',
  urls: {
    return_url: 'http://return.url',
    cancel_url: 'http://cancel.url'
  }
})

/* 
  Add the demo products
*/
demoBasket.add(demoProduct1)
demoBasket.add(demoProduct2)

/* Print current total */
console.log('Current total is: $' + demoBasket.total)

/*
  Now sell the basket (generate manifest)
  and perform actual payment request with external paypal sdk
*/
try {
  const manifest = await demoBasket.sell({ currency: 'USD', norequest: true })
  const payment = await paypal.payment.create(manifest)
  console.log("Payment Response:")
  console.log(payment)
} catch (err) {
  console.log(err)
}

Setup / Install

Use npm install @notixbit/paypal-basket
