Feature Request: Add CORS Support to the Signalling Server API

[Sohail05]

Component your feature request relates to:

• Signalling server
• Frontend library
• Frontend UI library
• Matchmaker
• SFU
• This repo

---

Problem your feature solves? Please describe.

I have enabled the API on the Signalling Server.
I am using a custom frontend hosted on a different domain and would like to retrieve information using the built-in API.

However, this currently does not work in the browser due to CORS restrictions. The browser blocks the requests, making it impossible to fetch data from the Signalling Server in this setup.

---

Describe the solution you'd like.

I propose adding parameters to the config.json file to enable and configure CORS on the API.

For example:

{
  "cors": {
    "enabled": true,
    "allowed_origins": ["http://example.com"],
    "allowed_methods": ["GET", "POST", "OPTIONS"],
    "allowed_headers": ["Content-Type", "Authorization"]
  }
}
