Can not run Node.Js on Drupal 8

I want to install Node.js on my Drupal 8 server to set up instant messaging.

I installed Node.js on Ubuntu 16.04 with the following command :

    # curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
    # apt-get update
    # apt-get install nodejs

My site is installed with "Composer" in `/home/www.domaine.com/public_html/web`

And entered the following commands :

(in `/home/www.domaine.com/public_html`)

    # npm install drupal-node.js
    # npm install pm2 -g

and :

    # cd node_modules/drupal-node.js
    # cp nodejs.config.js.example nodejs.config.js
    # nano nodejs.config.js

Here is my file `nodejs.config.js` :

    settings = {
      scheme: 'http',
      port: 8080,
      host: 'localhost',
      resource: '/socket.io',
      serviceKey: 'test',
      backend: {
        port: 443,
        host: 'domaine.com',
        scheme: 'https',
        basePath: '/web',
        messagePath: '/nodejs/message'
      },
      debug: true,
      sslKeyPath: '/etc/letsencrypt/live/www.domaine.com/privkey.pem',
      sslCertPath: '/etc/letsencrypt/live/www.domaine.com/cert.pem',
      sslCAPath: '',
      baseAuthPath: '/nodejs/',
      publishUrl: 'publish',
      kickUserUrl: 'user/kick/:uid',
      logoutUserUrl: 'user/logout/:authtoken',
      addUserToChannelUrl: 'user/channel/add/:channel/:uid',
      removeUserFromChannelUrl: 'user/channel/remove/:channel/:uid',
      addChannelUrl: 'channel/add/:channel',
      removeChannelUrl: 'channel/remove/:channel',
      setUserPresenceListUrl: 'user/presence-list/:uid/:uidList',
      addAuthTokenToChannelUrl: 'authtoken/channel/add/:channel/:uid',
      removeAuthTokenFromChannelUrl: 'authtoken/channel/remove/:channel/:uid',
      toggleDebugUrl: 'debug/toggle',
      contentTokenUrl: 'content/token',
      publishMessageToContentChannelUrl: 'content/token/message',
      extensions: [],
      clientsCanWriteToChannels: true,
      clientsCanWriteToClients: true,
      transports: ['websocket', 'flashsocket', 'htmlfile', 'xhr-polling', 'jsonp-polling'],
      jsMinification: true,
      jsEtag: true,
      logLevel: 1
    };

I installed the "Node.js integration" module on my site :

(in `/home/www.domaine.com/public_html`)

    # composer require drupal/nodejs
    # drush en -y nodejs_watchdog

Here is the configuration of the module :

I then enter the following commands and I clean the drupal cache :

(in `/home/www.domaine.com/public_html/node_modules/drupal-node.js`)

    # pm2 start app.js
    # pm2 logs

image2

drupal-node.js starts, but nothing works.

To cause a 404 error, I enter the address bar of the browser `https://www.domaine.com/shjsdhdshsd` The terminal displays :

publishMessageToContentChannel: The channel watchdog_dblog does not exist

that I simulate a 404 error or notification, the message is always the same.

The module "Node.js integration" looks completely dead, same for the module "Private Message".

There is absolutely nothing on Drupal 8 to exploit the Node.js technology

What solution is there to set up instant messaging on Drupal 8 ?

Has anyone managed to make Node.js work with Drupal 8 ?

If I update to the dev version, it does not work :
