如何在现有网站中实现 Node.js 聊天应用程序？

Question

I've been getting into Node.js recently and I really like the example shown on Socket.io's website showing a real time chat application. However, in all of the examples I see the URL used is localhost:8080 or whatever ip and port is applicable. However, is there any way to implement this into an existing webpage so that it isn't a separate URL? If not, how are these real-time chat apps done in real life?

Answer 1

these sort of questions are usually not meant for stackoverflow, but everyone has been where you are, Stackoverflow is dedicated for code related questions: but this might help you get to your next steps:

NodeJS is a backend server language, you will have to deploy it to a production environment.

New developers typically learn by using services like heroku.com to quickly host backend apps, they take a lot of the complexity of learning Linux or Microrost Server out of the mix, but they are not typically used by more advanced developers.

More advanced (real world apps) run on AWS/Azure/Other hosts.

Implementing it in an existing website requires both frontend and backend languages. Nodejs gives you a leg up in that it's javascript, and can run in both frontend and backend situations.

There are many places online that provide tutorials for creating backend servers and frontend websites.

the list is endless, but some good places for new developers are
