Shiny Module Overview

Shiny modules consist of a pair of functions that modularize, or package, a small piece of reusable functionality. The UI function is called directly by the user to place the UI in the correct location (as with other shiny UI objects). The module server function that is called only once to set it up using the module name as a function inside the server function (i.e. user-local session scope. The function first arguments is string represents the module id (the same id used in module UI function). Additional arguments can be supplied by the user based on the specific shiny module that is called. There can be additional helper functions that are a part of a shiny module.

The appReset Shiny Module is a part of the periscope2 package and consists of the following functions:

appResetButton

App Reset Toggle Button
Reset Warning
Cancel Reset
Canceled reset request
# Inside ui_body.R or similar UI file

appResetButton('appResetId')

appReset

The appReset function is called directly. The call consists of the following:

# Inside server_local.R

appReset(id = 'appResetId', logger = logger)

Sample Application

For a complete running shiny example application using the appReset module you can create and run a periscope2 sample application using:

library(periscope2)

app_dir = tempdir()
create_application(name = 'mysampleapp', location = app_dir, sample_app = TRUE)
runApp(paste(app_dir, 'mysampleapp', sep = .Platform$file.sep))
