Simple-Stripe wrapper module

The Simple-Stripe module is made with simplicity in mind, in order to provide basic Stripe Payments functionalities in the most readable API possible.

Requirements

Node 14 or higher.

Installation

Install the package with:

npm install simple-stripe --save
# or
yarn add simple-stripe

Usage

The package needs to be configured with your account's secret key, which is available in the Stripe Dashboard. Import it and create an instance like this :

import SimpleStripe, { StripeError } from "simple-stripe"
const simpleStripe = new SimpleStripe('sk_test_...')

Usage with TypeScript

Simple-Stripe provides its own type declarations

it also exposes StripeError as an export to ease Error handling

import SimpleStripe, { StripeError } from "simple-stripe"

Configuration

Initialize with config object

The package can be initialized with the usual StripeConfig parameters:

const simpleStripe = new SimpleStripe('sk_test_...', {
  apiVersion: '2019-08-08',
  maxNetworkRetries: 1,
  timeout: 1000,
  host: 'api.example.com',
  port: 123,
  telemetry: true,
});

API

paymentIntent

Exposes several methods used to handle paymentIntents

generate: async (amount: number, customer?: string, setupOffSession = false, currency = 'eur'): Promise<SimplePaymentIntent>
// creates a new paymentIntent on your Stripe Dashboard and returns it as a `SimplePaymentIntent` object

getClientSecret: async (id: paymentintent_id): Promise<string | null>
// Retreives the client secret of a payment intent

getStatus: async (id: paymentintent_id): Promise<PaymentIntentStatus>
// Retreives the status of the paymentIntent and wraps it in an enum

getDetails: async (id: paymentintent_id): Promise<PaymentIntentDetails>
// Retreives the details of a paymentIntent and provides the most interesting properties in a PaymentIntentDetails

// WIP
payOffSession: async (payment_intent: paymentintent_id, payment_method: paymentmethod_id ): Promise<SimplePaymentIntent>
// WIP
// Complete a payment of an existing paymentIntent server-side. Does not handle errors very well for now

customer

Exposes several methods used to handle customers

create: async (infos?: Stripe.CustomerCreateParams): Promise<SimpleCustomer>
// Creates a customer on your Stripe Dashboard and returns its id
// optional param "infos" are a Stripe.CustomerCreateParams object

findByEmail: async (infos?: Stripe.CustomerCreateParams): Promise<SimpleCustomer>
// Finds a list of customers based on email

getDetails: async (id: customer_id): Promise<CustomerDetails>
// Get a customer's details and wraps them inside a CustomerDetails object

getPaymentMethods: async (id: customer_id): Promise<PaymentMethod[]>
// Returns the details of a customer's PaymentMethod[]
// This could be useful to send a list of saved card to a front-end

flushDuplicatePaymentMethods: async (id: customer_id): Promise<number>
// Go through a customer's payment cards, find duplicates and detach the older ones
// This is good to call before sending payment methods infos to a front-end to prevent duplicates

charge: async (
    customer: customer_id,
    payment_method: paymentmethod_id,
    amount: number,
    currency = 'eur',): Promise<SimplePaymentIntent | void>
// This method can charge an off_session saved payment id, and returns the result in form of a SimplePaymentIntent object

Types

This module is written 100% in TypeScript, you can find the types in the src folder on the GitHub repository

Roadmap

This module is a work in progress.

First major milestome will be to wrap everything in structured classes, e.g :

class Customer{
  public id: string
  public name: string
  public created: Date
  public ...
  ...
  public paymentCards: PaymentCard[] // inherits from PaymentMethod etc..
  public paymentIntents: PaymentIntent[]

  constructor(id: string, options: tbd){
    // fetch the customer, its payment methods and intents etc...
  }

  // Static methods to create or retreive a Customer?

  // methods to charge the customer, retreive information ...
}

Following work will focus on supporting more scenarios :

• Subscriptions
• Card holds and captures
• Support for SEPA transferts
• Support for Apple Pay transactions (nothing much to do backend)

Let's keep it simple though, I don't plan on supporting everything Stripe does

Collaboration
