Board server — board_server • blockr.core

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 class 'board'
board_server(
  id,
  x,
  plugins = board_plugins(x),
  options = board_options(x),
  callbacks = list(),
  callback_location = c("end", "start"),
  ...
)

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)

Value

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