Need to create an online chat on js socetio and using api?

Question

JavaScript

I have a site where I need to create an online chat for all users, is there any documentation on this issue, and is it possible to implement this only in js without php?

Answer 1

Can.

1. You can write js on the server (Node.js)
   
2. You can generally do without a server with all sorts of serverless products
   
3. Can be generally ready to attach
   

Answer 2

Yes, you can write a server on node.js/express.js. JavaScript has been allowing you to write server-side applications for many years, but I recommend using a framework rather than reinventing the wheel. Try exppress first, then nest.js when you get comfortable with express. All the documentation is available on the official websites of these technologies, in addition, this ecosystem has a huge community, a huge number of examples, video tutorials, etc.
