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)
[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)
Custom connection settings
If you have the Notification Catcher running on a custom port, domain, or you need to change any other connection setting, set the environment variable NOTIFME_CATCHER_OPTIONS
with your custom connection smtp url.
$ # Example
$ NOTIFME_CATCHER_OPTIONS=smtp://127.0.0.1:3025?ignoreTLS=true node your-script-using-notifme.js
How to use
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
}]

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)
}
Adding a provider or a channel
If you would like to see another provider or channel, please upvote the corresponding issue (or create one if it does not exist yet).
3. Custom channels
If you want to have custom channels (and providers) you can add them.
Example:
Custom channel and provider
new NotifmeSdk({
channels: {
socket: {
multiProviderStrategy: 'fallback',
providers: [
{
type: 'custom',
id: 'my-socket-sender',
send: async () => {
return 'custom-socket-id'

5. 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 ;)

Next for this project
- Implement other providers for each channel (ask or vote for a provider)
- Add other types of notifications based on what people ask (slack, messenger, skype, telegram, kik, spark...)
- A plugin system (for queues, retry system on error, templating, strategies...)
