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 first function argument is a string that 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 logViewer Shiny Module is a part of the periscope2 package and consists of the following functions:

logViewerOutput

The logViewerOutput function is called from the ui_body.R (or equivalent) file in the location where any other UI element (box) can be placed.

# Inside ui_body.R

logViewerOutput("logViewerId")

Sample Application

For a complete running shiny example application using the logViewer 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))
