R Shiny template

[eroten]

We need a function that will create an R Shiny app from a template.

Needs

• Standardized CSS
• Bare bones UI and server
• Checklists for accessibility
• Frequently used libraries, such as {data.table}, {ggplot2}, {plotly}, etc.
• Example elements (we can use {shinipsum})
• FAQs and links to all other CD/MTS Shiny apps (once we have all our GH repos topic tagged with shiny and golem, this would be fairly easy to generate automatically).

Ideas

• A {usethis} type function
• Something like golem::create_golem()
• See MetroTransitR::load-shiny-template.R

Note; use tags @shiny @shiny-apps @golem-apps

App styling

• logo and favicon, as seen here
• colors.css
  • includes the full series of blue gradients and corresponding text colors for cascading menus on metrocouncil.org
• font.css
  • Only works when accompanied by the relevant .woff files
• shinydashboard element styling
  • boxes! wells! modals! Examples here

Element specific styling

• Plotly
  • hide plotly online toolbar
  • Standard layout() (example here)
• Leaflet
  • tooltip, legend, layer control styling. Example here
  • CTU names with highest zIndex (see examples here and here)
  • including scale, pseudo full screen
• DT
  • fonts, row striping. Example here
• gt
  • fonts, row striping

IDEALLY we would create a fully-fledged bootstrap theme, created with something like {bslib}

Standard elements

These are not all absolutely essential for every app, but are a good starting point

• data download
• documentation
• explainers (likely using {shinyhelper})
• icons! like those used here
  • FontAwesome would be easier to use
• MIT license and MetC as copyright holder
