Ember fastboot-app-server notifier which polls for filesystem events to restart server. Polls to support use within virtual machines (e.g. Vagrant vm dev box with NFS mounted source).

fastboot-watch-notifier.js

const debounce = require('debounce')
const FastBootAppServer = require('fastboot-app-server')
const Sane = require('sane')

const distPath = '/app/dist'

const server = new FastBootAppServer({
  distPath,
  notifier: {
    subscribe(notify) {
      const watcher = new Sane(distPath, { poll: true })
      watcher.on('all', debounce(notify, 100))
      return Promise.resolve()
    },
  },
})

server.start();
