smpp-gateway

Module provides SMPP External Short Messaging Entity (ESME) behaviour 'out of the box'.

It also contains Express routers for HTTP to SMPP gateway and Prometheus metrics.

Usage example

const express = require('express')
const app = express()

const { ESME, gateway, metrics } = require('smpp-gateway')
const config = {} // see examples/client.js

const esme = new ESME(config)

esme.on('ready', async() => {
  await esme.sendMessage({
    destination: '111',
    content: 'hello',
    udh: {
      port: {
        src: 37273,
        dst: 37273
      }
    }
  })
})

app.use('/send', gateway(esme))
app.use('/metrics', metrics(esme))

esme.connect()

app.listen(3000)

Example JSON body for HTTP request

{
  "destination": "111",
  "content": "hello",
  "udh": {
    "port": {
      "src": 37273,
      "dst": 37273
    }
  }
}
