board_server: Board server

Description

A call to board_server(), dispatched on objects inheriting from board, returns a shiny::moduleServer(), containing all necessary logic to manipulate board components via UI. Extensibility over currently available functionality is provided in the form of S3, where a board_server() implementation of board sub-classes may be provided, as well as via a plugin architecture and callback functions which can be used to register additional observers.

Usage

board_server(id, x, ...)
# S3 method for board
board_server(
  id,
  x,
  plugins = board_plugins(x),
  options = board_options(x),
  callbacks = list(),
  callback_location = c("end", "start"),
  ...
)

Value

A board_server() implementation (such as the default for the board base class) is expected to return a shiny::moduleServer().

Arguments

id

Parent namespace

x

Board

...

Generic consistency

plugins

Board plugins as modules

options

Board options (NULL defaults to the union of board, block and registry sourced options)

callbacks

Single (or list of) callback function(s), called only for their side-effects)

callback_location

Location of callback invocation (before or after plugins)
