Shiny app which depends on package on GitHub?

[Rainer]

I want to deploy a shiny app which depends on a package on GitHub - how can I do this? All tries failed, as the package can not be installed as it is not on CRAN?

I get the following messages, even though I have the following lines on top of the ui.R and sever.R:

  library(remotes)
  remotes::install_github("Exp-Micro-Ecol-Hub/dmdScheme", ref = "separateDefinition")
  library(dmdScheme)

You should not install packages inside your shiny app, just install it locally and rsconnect will figure out how to install it based on your local library, you just have to load the library inside your app.

Some additional documentation on the subject.
