spsComps
A collection of custom Shiny UI and server components that help developers build richer, more interactive apps.
spsComps is a toolbox of Shiny UI and server components for the things base Shiny leaves out — animations, loading spinners, a whole family of buttons, galleries, tooltips, progress panels, and timelines, plus server-side helpers for updating UI and validating input.
Most components are self-contained and lean on bundled JavaScript and CSS, so many work not just in Shiny apps but directly inside R Markdown. It was carved out of systemPipeShiny for reuse, and ships on CRAN with a live gallery demoing every component.
