在 bslib 包和 Shinydashboard 上

Question

This a question on bslib, by the way, a great package.

I'd like to know if it is primarily intended for shiny and flexdashborad or it will be also operative with shinydashboard.

Thanks!

Answer 1

bslib is not intended to be used with shinydaashboard and should instead be leveraged in conjunction with shiny . Granted, you shouldn't have issues using bslib for flexdashboard , please see the Theming {flexdashboard} writeup . To elaborate more on Shiny, some additional thoughts:

• shinydashboard provides new verbs for theming your Shiny apps for use with Bootstrap 3 + AdminLTE v2.4 HTML templates
• bslib makes it easy to customize "stock" Shiny apps with modern Bootstrap 4 (or 5) themes - This is accomplished through the introduction of Sass variables for use with Shiny and R Markdown and bslib pre-packages Bootswatch themes without the need to load other packages
• The customization of your bslib themes can be further expanded by using Sassy CSS (you'll need a custom *.scss file as opposed to a *.css file)

The RinteRface team have done an excellent job developing the bs4Dash package to solve the problem that I believe you're attempting to solve, ie, using newer Bootstrap themes on top of the shinydashboard framework. More on the bs4Dash package:

• shinydashboard is the basis of bs4Dash with 1:1 support so upgrading your old apps to bs4Dash can be accomplished by simply changing library(shinydashboard) to library(bs4Dash)
• bs4Dash brings Bootstrap 4 + AdminLTE v3.1 dependencies to your traditional shinydashboard templates
• On the Introduction page of the bs4Dash pkgdown site, there is a table comparing the features of shinydashboard , shinydashboardPlus , and bs4Dash (the latter two being developed by the RinteRface team)
