Is it possible to run a golem application on shiny-server?

[gioneves]

I have a shiny app (golem) and I would like to put it on a shiny-server (locally).

golem::add_shinyserver_file()

Which creates an app.R file.

I downloaded the package with devtools::install_github() in other computer.

And I put the folder of this package inside srv/shiny-server/

Suppose my package name is mygolempackage, this is what appears when I run it http://192.000.0.000:3838/mygolempackage/:

When I run a conventional app (with .ui and .server files), it works normally.

But I would like to know if there is a possibility to serve other users through a packaged shiny (created with golem). I appreciate the support.

golem::add_shinyserver_file() should add mygolempackage/app.R. It looks like you're missing that file.

yes, the app.R file is missing in your server.

do you manage to deploy your app ?

✔ Created

• rsconnect::deployApp()

• Note that you'll need to upload the whole package to Shiny Server

• As you can see the app.R is created to inside the package.

• The note does state that you'll need to upload the whole folder to your server (I agree though that the message could be made clearer)

• Note that you'll need to upload the whole package to Shiny Server

• If you need to deploy after installing from remotes::install_github() or via a package manager, you'll need to create the app.R file yourself, with the following code mypkg::run_app() . This solution is documented here : https://engineering-shiny.org/deploy.html#rstudio-environments, but this should be documented in the vignette too.

Let me know if this helps :)

do you manage to deploy your app ?

I can not. I already inserted the app.R file and it doesn't work.

I can't leave the source code with the client, just the package. I put the app.R file in the package folder, but now another error appears:

An error has occurred
The application failed to start.

The application exited during initialization.

Thank you for your support.

As far as I can tell, the message on a server

An error has occurred
The application failed to start.

The application exited during initialization.

Is not link to golem but to an issue with the app itself.

I'm closing it as it's an old issue and I'm not sure i can still help :)

But if ever, feel free to comment and I'll reopen
