module_template: Golem Module Template Function

Description

Module template can be used to extend golem module creation mechanism with your own template, so that you can be even more productive when building your {shiny} app. Module template functions do not aim at being called as is by users, but to be passed as an argument to the add_module() function.

Usage

module_template(name, path, export, ph_ui = " ", ph_server = " ", ...)

Value

Used for side effect

Arguments

name: The name of the module.
path: The path to the R script where the module will be written. Note that this path will not be set by the user but via add_module().
export: Should the module be exported? Default is FALSE.
ph_ui, ph_server: Texts to insert inside the modules UI and server. For advanced use.
...: Arguments to be passed to the module_template function.

Details

Module template functions are a way to define your own template function for module. A template function that can take the following arguments to be passed from add_module():

name: the name of the module
path: the path to the file in R/
export: a TRUE/FALSE set by the export param of add_module()

If you want your function to ignore these parameters, set ... as the last argument of your function, then these will be ignored. See the examples section of this help.

  my_other_tmpl <- function(name, path, ...) {
    # Copy and paste a file from somewhere
