API

const pm = require('toa-pm')

pm(app[, handle])

It will add handle to process's message event, or add one more event-handle to process. ** Use it after app.listen **

• app: Toa application.

• handle: {Function|Object}, if omit handle, the default handle will be used:

  function defaultHandle(message) {
    if (message === 'shutdown') {
      this.server.close(() => process.exit(0))
    }
  }

  Default handle accept a 'shutdown' message to stop from accepting new connections and keeps existing connections. The server is finally closed and exit gracefully when all connections are ended. For example: pm2 gracefulReload app
