Because of delays with my scholarship payment, if this post is useful to you I kindly ask a minimal donation on Buy Me a Coffee. It shall be used to continue my Open Source efforts. The full explanation is here: A Personal Message from an Open Source Contributor. If you play the electric guitar, the same scholarship chaos led me to turn my guitar pedals and DIY kits hobby into a business, and you can check those here.
I uploaded a Shiny app made with Golem to Shiny Apps for a live demo. I had to troubleshoot a few issues with the deployment so here are the steps I used. I hope this is useful 🙂
After creating a Shiny app skeleton with golem::create_golem("pkgname") you can create an app such as the 2×2 Cobb-Douglas General Equilibrium viewer (code on [GitHub(https://github.com/pachadotdev/cobbdouglasge]).
When I tried to deploy that Cobb-Douglas app to ShinyApps.io I got this message:
> rsconnect::deployApp() ℹ Capturing R dependencies The following package(s) were installed from an unknown source: - cobbdouglasge [0.0.0.9000] renv may be unable to restore these packages in the future. Consider reinstalling these packages from a known source (e.g. CRAN). Error in renv_snapshot_validate_report(valid, prompt, force) : aborting snapshot due to pre-flight validation failure
The cause of the problem is that when testing my app, I installed it locally with devtools::install(), and ShinyApps needs CRAN or GitHub as a source for the dependencies.
To remedy that, I added the following to dev/03_deploy.R without running it:
golem::add_shinyappsio_file()
remotes::install_github("pachadotdev/cobbdouglasge")
use_git_ignore("rsconnect/")
rsconnect::deployApp()
I know pak is the standard these days, but it gave me a compilation error when I tried to install it, so I used remotes.
As an optional step to save space in my ShinyApps account, I created the file .rscignore containing:
.here CODE_OF_CONDUCT.md LICENSE* NEWS* README* dev man vignettes tests
Then I ran the previous chunk that allowed me to deploy the Cobb-Douglas app without errors.
