How to use exportModule

Introduction

scissor’s exportModule export (download) inputData, which is transformed by other scissor’s functions.

In this article, we’ll use scholarship dataset of datatoys

This article is based on 0.2.0 Version of scissor

Declare module

scissor’s module assumes that used in the Shiny application.

and You can use snippet(type shinyapp) to build very basic shiny application.

library(shiny)

ui <- fluidPage(
 
)

server <- function(input, output, session) {
  
}

shinyApp(ui, server)

This application will show nothing.

So let’s add exportModule in ui.

ui <- fluidPage(
  mod_exportModule_ui(
    id = 'module'
  )
)

also, exportModule in server.

server <- function(input, output, session) {
  mod_exportModule_server(
    id = "module", 
    inputData = reactive(datatoys::scholarship)
  )
}

So final (which is very basic) code will like this.

library(shiny)

ui <- fluidPage(
  mod_exportModule_ui(
    id = 'module'
  )
)

server <- function(input, output, session) {
  mod_exportModule_server(
    id = "module", 
    inputData = reactive(datatoys::scholarship) # remotes::install_github('statgarten/datatoys')
  )  
}

shinyApp(ui, server) # run application

You should notice 3 things.

1. both id in ui and server should be same.
2. inputData in server should be format of reactive

Structure of reorderModule

exportModule is consisted with Control Area

and below using flow.

1. Declare module (we did already)
2. select output format and filename (like ‘download.csv’)
3. Export

Usage of reorderModule

You can select csv, xlsx, rda and sqlite.
