Features

Easy channel integration — Want to start sending emails | SMS | pushes | webpushes | slack? Do so in no time!
Unique documentation — Don't look everywhere for the parameters you need to pass, just do it once. Switching provider becomes a no-brainer.
Multiple providers strategies — Want to use more than one provider? Use fallback and round-robin strategies out of the box.
Tools for local testing — Run a catcher locally to intercept all your notifications and display them in a web interface.
MIT license — Use it like you want.

Getting Started

$ yarn add notifme-sdk

import NotifmeSdk from 'notifme-sdk'

const notifmeSdk = new NotifmeSdk({}) // empty config = all providers are set to console.log
notifmeSdk
  .send({sms: {from: '+15000000000', to: '+15000000001', text: 'Hello, how are you?'}})
  .then(console.log)

✨ Congratulations, you should see the following lines in your console:

[Recommended] Setup Notification Catcher for your local tests

Notification Catcher is a web interface for viewing and testing notifications during development.

$ yarn add --dev notification-catcher
$ yarn run notification-catcher

import NotifmeSdk from 'notifme-sdk'

const notifmeSdk = new NotifmeSdk({
  useNotificationCatcher: true // <= this sends all your notifications to the catcher running on port 1025
})
notifmeSdk
  .send({sms: {from: '+15000000000', to: '+15000000001', text: 'Hello, how are you?'}})
  .then(console.log)

😻 Open http://localhost:1080 on your favorite browser, you should see the notification:

1. General options

new NotifmeSdk({
  channels: ..., // Object
  useNotificationCatcher: ... // boolean
})

Option name	Required	Type	Description
`channels`	`false`	`Object`	Define `providers` (`Array`) and `multiProviderStrategy` (`string`) for each channel (email, sms, push, webpush, slack). See all details below: 2. Providers.
`useNotificationCatcher`	`false`	`boolean`	If true, all your notifications are sent to the catcher running on localhost:1025 (channels option will be completely ignored!)

Complete examples

// Env: development
new NotifmeSdk({
  useNotificationCatcher: true
})

// Env: production
new NotifmeSdk({
  channels: {
    email: {
      // If "Provider1" fails, use "Provider2"
      multiProviderStrategy: 'fallback',
      providers: [{
        type: 'Provider1',
        // ...credentials
      }, {
        type: 'Provider2',
        // ...credentials
      }]
    },
    sms: {
      // Use "Provider1" and "Provider2" in turns (and fallback if error)
      multiProviderStrategy: 'roundrobin',
      providers: [{
        type: 'Provider1',
        // ...credentials
      }, {
        type: 'Provider2',
        // ...credentials
      }]
    }
  }
})

HTTP proxy option

If you want to use a HTTP proxy, set an environment variable NOTIFME_HTTP_PROXY.

$ # Example
$ NOTIFME_HTTP_PROXY=http://127.0.0.1:8580 node your-script-using-notifme.js

Multi-provider strategies

A multi-provider strategy allows you to customize the send process on a channel.

Predefined strategies

Strategy name	Description
`fallback`	If the used provider returns an error, try the next in the list.
`roundrobin`	Use every provider in turns. If one of them returns an error, fallback to the next.
`no-fallback`	Deactivates fallback strategy.

Custom

You can also provide your own strategy. You have to pass a function implementing:

(Provider[]) => Sender
// See examples below for more details

Examples:

Random strategy

/*
 * `providers` is an array containing all the instances that were
 * created from your configuration.
 */
const randomStrategy = (providers) => async (request) => {
  // Choose one provider at random
  const provider = providers[Math.floor(Math.random() * providers.length)];

  try {
    const id = await provider.send(request)
    return {id, providerId: provider.id}
  } catch (error) {
    error.providerId = provider.id
    throw error
  }
}

new NotifmeSdk({
  channels: {
    email: { // Example for email channel
      providers: [...],
      multiProviderStrategy: randomStrategy
    }
  }
})

Cheap SMS strategy with fallback

import strategyFallback from 'notifme-sdk/lib/strategies/fallback'

function getCountryFromNumber(number) {
  // extract the country from a phone number (+33670707070) -> 'fr'
}
function orderProvidersByPrice(country, providers) {
  // giving a country return an array of ordered providers by price
}

const smsCheapStrategy = (providers) => async (request) => {
  const country = getCountryFromNumber(request.from)
  const providersOrdered = orderProvidersByPrice(country, providers)

  return strategyFallback(providersOrdered)(request)
}

Returned type

send returns a Promise resolving with an Object of the following type:

  status: 'success' | 'error',
  channels?: {[channel: ChannelType]: {
    id: string,
    providerId: ?string
  }},
  errors?: {[channel: ChannelType]: Error}
}

Examples:

Case	Returned JSON
Success (when Promise resolves)	`{status: 'success', channels: {sms: {id: 'id-116561976', providerId: 'sms-default-provider'}}}`
Error (here Notification Catcher is not running)	`{status: 'error', channels: {sms: {id: undefined, providerId: 'sms-notificationcatcher-provider'}}, errors: {sms: 'connect ECONNREFUSED 127.0.0.1:1025'}}`

4. In production

Recommended options

Option name	Usage in production	Comment
useNotificationCatcher	`false`	Don't forget to deactivate notification catcher (it overrides channels configuration).

Logger

This project uses winston as logging library. You can add or remove loggers as you wish.

import NotifmeSdk from 'notifme-sdk'
import winston from 'winston'

const notifmeSdk = new NotifmeSdk({})

// To deactivate all loggers
notifmeSdk.logger.mute()

// Or set the loggers you want
notifmeSdk.logger.configure([
  new (winston.transports.File)({filename: 'somefile.log'})
])

See winston's documentation for more details.

Use a request queue

RabbitMQ: see RabbitMQ Notif.me plugin documentation.

Send us a message

So that we can make a list of people using this library ;)
