## 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
```shell
$ yarn add notifme-sdk
```
```javascript
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)
```
:sparkles: Congratulations, you should see the following lines in your console:
### [Recommended] Setup Notification Catcher for your local tests
[Notification Catcher](https://github.com/notifme/catcher) is a web interface for viewing and testing notifications during development.
```shell
$ yarn add --dev notification-catcher
$ yarn run notification-catcher
```
```javascript
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)
```
:heart_eyes_cat: Open [http://localhost:1080](http://localhost:1080) on your favorite browser, you should see the notification:
#### 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](https://nodemailer.com/smtp/).
```shell
$ # Example
$ NOTIFME_CATCHER_OPTIONS=smtp://127.0.0.1:3025?ignoreTLS=true node your-script-using-notifme.js
```
## How to use
- [1. General options](#1-general-options)
- [2. Providers](#2-providers)
- [3. Custom channels](#3-custom-channels)
- [4. Send a notification](#4-send-a-notification)
- [5. In production](#5-in-production)
### 1. General options
```javascript
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](#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
```javascript
// 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`.

#### 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:
```javascript
(Provider[]) => Sender
// See examples below for more details
```
Examples:
Random strategy
```javascript
/*
* `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
```javascript
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](https://github.com/notifme/notifme-sdk/issues) (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'
}
}
]
}
}
})
```

#### Returned type
`send` returns a Promise resolving with an `Object` of the following type:
```javascript
type NotificationStatusType = {
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'}}` |
### 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](https://github.com/winstonjs/winston) as logging library. You can add or remove loggers as you wish.
```javascript
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](https://github.com/winstonjs/winston) for more details.
#### Use a request queue
- RabbitMQ: see [RabbitMQ Notif.me plugin documentation](https://github.com/notifme/notifme-sdk-queue-rabbitmq).
#### 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](https://github.com/notifme/notifme-sdk/issues))
- 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...)
