Hello! How to implement multi-user problems with the TRARE framework. Note that for multi-users you need to use and configure a launcher.

We expose a [docker image](https://github.com/Kitware/trame/tree/master/docker) on which you can install your trame app. That docker image will handle the multi-user setup for you.
We have a [single file trame app example](https://github.com/Kitware/trame-app-cone) making use of that docker.
Also if you use the [cookiecutter](https://github.com/Kitware/trame-cookiecutter) to build your trame application it will provide a setup for bundling your app into such docker image as well.

What are you asking? How to delete the import for the setup\_dev or something else?
That part was deprecated to use the new infrastructure that support hot reloading…

If all the infromation above is not enough, you can use [that caprover demo](https://github.com/Kitware/trame-app-cone).

app.py we run the trame framework, two URLs appear, why can’t the second one be accessed? Why can’t the network be accessed?

On linux, you need to set the host to 0.0.0.0 (`--host 0.0.0.0`) otherwise it is not accessible from another machine.

Hi @Sebastien_Jourdain
I tried using wslink to connect to trame-server. How can the client send messages to be received by the trame-server?

It might be easier to use the JS library for trame which rely on wslink.

You can also look at the code to see which RPC + pub/sub endpoints we have with trame-server.
