Usage

Electron example:

const path = require('path')
const fs = require('fs')
const { fork } = require('child_process')
const { remote } = require('electron')
const userDataPath = remote.app.getPath('userData')
const filePath = path.join(__dirname, '/node_modules/telios-client-backend/index.js')

let cwd = path.join(__dirname, '..');

if (!fs.existsSync(path.join(cwd, 'app.asar'))) {
  cwd = null;
}

const child = fork(filePath, [userDataPath, 'development', 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:107.0) Gecko/20100101 Firefox/107.0'], {
  stdio: ['pipe', 'pipe', 'pipe', 'ipc'],
  cwd
})

// listen for channel events
child.on('message', m => {
  const { event } = m
  
  this.emit(event, m)
})

child.stderr.on('error', data => {
  this.emit('error', data.toString())
})

// Send channel events
child.send({ 
  event: 'account:create', 
  payload: {
    email: '[email protected]',
    password: 'letmein123',
    vcode: 'btester1',
    recoveryEmail: '[email protected]'

Custom Domains API

channel.send({ event: 'domain:isAvailable', payload })

Checks if a domain has already been registered.

const payload = {
  domain: 'telios.app'
}

Example response:

// Use verification to send DNS instructions for creating verifcation TXT record
{
  domain: "telios.app",
  verification: {
    name: "@",

  }
}

channel.send({ event: 'domain:verifyOwnership', payload })

Verify that the user owns the domain they're trying to register. Once verified, the domain is created on the mailserver. Mail will not start routing through this domain until all checks are passed on the verifyDNS step.

const payload = {
  domain: 'telios.app'
}

channel.send({ event: 'domain:verifyDNS', payload })

Returns additional DNS records that need to be set and their verification status. Once all records have been verified, the domain is set to active and mail will start being delivered.

  domain: 'telios.app'
}

Example response:

[
