Learn how to configure the UWS HTTP Service

UWS is enabled throughout all endpoints by setting the httpServer type to uws.


UWS does not work on alpine images and returns C++ error traces on failure. If you run into a bug please try it out with the default http server to see if it can be reproduced on both types.

Currently uws doesn’t have as many configurations options as the node server, but this will be expanded in the future, please raise an issue for anything you thing is missing.

To enable SSL on uws, all you need to do is pass in the location to a key and cert.

You can either do this using an explicit path:

key: /location/to/ssl/key.pem

or relative to the config file (less likely on a production install):

key: file(relative/to/config/ssl/key.pem)

How to configure:

  type: uws
    # url path for http health-checks, GET requests to this path will return 200 if deepstream is alive
    healthCheckPath: /health-check
    # Headers to copy over from websocket
      - user-agent
    # Options required to create an ssl app
    # ssl:
    #   key: file(ssl/key.pem)
    #   cert: file(ssl/cert.pem)
    ##  dhParams: ...
    ##  passphrase: ...
