В настоящее время я пытаюсь внедрить функцию живого чата на своем веб-сайте с помощью Node.js и Heroku. Я сделал все возможное, чтобы выполнить следующие шаги для развертывания безрезультатно: http://tutorialzine.com/2014/03/nodejs-private-webchat/
Я создал исходный чат-сервер, просмотрев следующие обучающие видео: https://www.youtube.com/playlist?list=PLfdtiltiRHWHZh8C2G0xNRbcf0uyYzzK_
Одна вещь, которая меня озадачивает, это то, что у меня нет файла app.js, который описан в пошаговом руководстве по первой ссылке, которую я разместил. Это просто похоже на мой server.js?
Вот мой код:
HTML (ОБНОВЛЕНО): (у меня есть скрипт на пару строк ниже кода src="http://127.0.0.1:8080/socket.io/socket.io.js" мне нужно удалить/отредактировать это? Я' мы уже удалили локальный хост из var socket = io.connect();)
