moleculer-stripe

Stripe product available in this service

Ready for new PSD2 EU reglementations (SCA)

How to use it

const StripeMixin = require('moleculer-stripe')

module.exports = {
  name: 'stripe',
  mixins: [StripeMixin],
  settings: {
    stripe: {
      /** @type {String} Secret key from Stripe dashboard. */
      secret: 'pk_',
      /* Before using webhook look in the README how to integrate it */
      webhook: {
        /** @type {Object?} Platefrom webhook (Default webhooks) */
        platform: {
          /** @type {String} Webhook signing from Stripe dashboard. */
          key: 'whsec_',
          /** @type {String?} Which action will be call when a webhook is received */
          action: undefined,
          /** @type {String?} Which event will be emitted when a webhook is received */
          event: undefined
        },
        /** @type {Object?} Connect webhook (Only if you use connect) */
        connect: {
          /** @type {String} Webhook signing from Stripe dashboard. */
          key: 'whsec_',
          /** @type {String?} Which action will be call when a webhook is received */
          action: undefined,
          /** @type {String?} Which event will be emitted when a webhook is received */
          event: undefined
        }
      },
      /** @type {String?} Version of this API (Default : latest). */
      version: undefined,
      /** @type {Boolean?} Enable/Disable telemetry for stripe (Default : true). */
      telemetry: true,
      /** @type {Function?} Custom function for config stripe, like setAppInfo for your plugin, ... (First args is stripe instance). */
      custom: undefined
    }
  }
}

All this options can be per call based :

const customStripeOptions = {
  secret: 'pk_',
  version: '2019-08-26',
  telemetry: false
}
broker.call('stripe.payment.intents.create', charge, { meta: { stripe: customStripeOptions } })

When using with Connect you can have an account meta (It's the stripe_account from the Connect documentation)

broker.call('stripe.payment.intents.create', charge, { meta: { stripe: { account: 'acc_' } } })

You can go further with stripe and there idempotency key (Because the Stripe API is freaking well thought)

// Get autogenerated idempotency key (UUID V4)
await ctx.call('stripe.payment.intents.create', charge)
console.log(ctx.meta.stripe.idempotency)

// Or you want to use from your side
await ctx.call('stripe.payment.intents.create', charge, { meta: { stripe: { idempotency: UUIDV4() } } })

Webhooks

Integration with moleculer-web

Declare your stripe service like above :

const StripeMixin = require('moleculer-stripe')

module.exports = {
  name: 'my.stripe.service',
  mixins: [StripeMixin],
  settings: { ... }
}

And in your web service add one route with the path of your webhook and the name of the stripe service :

const MoleculerWeb = require('moleculer-web')
const { StripeRoute } = require('moleculer-stripe')

module.exports = {
  name: 'web',
  mixins: [MoleculerWeb],
  settings: {
    routes: [StripeRoute('/webhook/stripe', 'my.stripe.service')]
  }
}

If you want to use Connect webhook, just add a third arguement at true :

const MoleculerWeb = require('moleculer-web')
const { StripeRoute } = require('moleculer-stripe')

module.exports = {
  name: 'web',
  mixins: [MoleculerWeb],
  settings: {
    routes: [StripeRoute('/webhook/stripe/platform', 'my.stripe.service'), StripeRoute('/webhook/stripe/connect', 'my.stripe.service', true)]
  }
}

If you want more "Pimp my ride" options on this route, look at src/index.js#78

Integration with any other web gateway

Declare your stripe service like above :

const StripeMixin = require('moleculer-stripe')

module.exports = {
  name: 'my.stripe.service',
  mixins: [StripeMixin],
  settings: { ... }
}

Then you need to call a specific action with the body of the webhook (:warning: RAW Body, not json parsed :warning:)

// Example with express (If you use that, checkout the offical 'moleculer-web')
// Do your express init things + moleculer init broker
app.post('/webhook/stripe', bodyParser.raw({ type: 'application/json' }), async (request, response) => {
  const result = await broker.call('my.stripe.service.webhook', { body: request.body, signature: request.headers['stripe-signature'], connect: false })
  return result ? response.json(result) : response.status(400).end()
})

API

A possiblity for every list actions, is to use 'autoPagination' from stripe node lib :

// When it's a number it will use `autoPagingToArray` and use the value of `pagination` as the limit
ctx.call('stripe.payment.intents.list', {}, { meta: { pagination: 10000 } })
// When i's a string it will use `autoPagingEach` and use the value of `pagination` as the action to call for each and pass the item as parameter
ctx.call('stripe.payment.intents.list', {}, { meta: { pagination: 'my.service.each.payment' } })

// Service will receive item from list
module.exports = {
  name: 'my.service',
  actions: {
    // Params is the stripe item
    'each.payment': ({ params }) => console.log(params.id, params.amount)
  }
}
