In fresh: Create Custom 'Bootstrap' Themes to Use in 'Shiny'

Create a custom Bootstrap theme

Description

Allow to customize some CSS variables from Bootstrap themes to be included in Shiny applications.

Usage

create_theme(
  ...,
  theme = c("default", "cerulean", "cosmo", "cyborg", "darkly", "flatly", "journal",
    "lumen", "paper", "readable", "sandstone", "simplex", "slate", "spacelab",
    "superhero", "united", "yeti"),
  output_file = NULL,
  include_assets = FALSE
)

Arguments

...	Lists of CSS variables declared with bs_vars_* or adminlte_* functions.
theme	Base theme to use.
output_file	Specifies path to output file for compiled CSS.
include_assets	Logical. Only use if output_file is not NULL, it will copy fonts file used in Bootstrap and Bootswatch themes. Note that output path will be modified to add an intermediate directory "stylesheets" where the CSS file will be located.

Value

If output_file = NULL, the function returns a string value of the compiled CSS. If the output path is specified, the compiled CSS is written to that file and invisible() is returned.

Examples

# using a temporary file but use the path you want
tmp <- file.path(tempdir(), "custom-theme.css")

# Create the new theme
create_theme(
  theme = "default",
  bs_vars_color(
    brand_primary = "#75b8d1",
    brand_success = "#c9d175",
    brand_info = "#758bd1",
    brand_warning = "#d1ab75",
    brand_danger = "#d175b8"
  ),
  bs_vars_navbar(
    default_bg = "#75b8d1",
    default_color = "#FFFFFF",
    default_link_color = "#FFFFFF",
    default_link_active_color = "#FFFFFF"
  ),
  output_file = tmp
)

# Use the file created at the path provided
# in your Shiny app by moving it in the
# www/ folder, then use it in UI

library(shiny)
fluidPage(
  theme = "custom-theme.css"
)

# clean up
unlink(tmp)
