[template-helpers] propose default QoS for node clients and server

[b-ma]

description

We could have:

• import initQoS from '@soundworks/template-helpers/client/init-qos-browser.js';
• import initQoS from '@soundworks/template-helpers/client/init-qos-node.js';
• import initQoS from '@soundworks/template-helpers/server/init-qos.js';

Even better would be to hide init-qos-browser.js and init-qos-node.js behind the same init-qos.js file, it would not require a major version

examples

node clients

function exitHandler(msg) {
  console.log(msg);
  pd.destroy(); 

  console.log('------------------------- TERM');
  process.kill(process.pid, 'SIGKILL');
}

function initQoS(client) {
  client.socket.addListener('close', () => {
    exitHandler('Disconnected from server');
  });

  process.on('exit', () => exitHandler('none'));
  process.on('uncaughtException', err => exitHandler(err));
  process.on('unhandledRejection', err => exitHandler(err));
}

server

we could at least have something like:

process.on('unhandledRejection', err => exitHandler(err));
