initStore: Included package scripts

In shinyStorePlus: Secure in-Browser and Database Storage for 'shiny' Inputs, Outputs, Views and User Likes

Included package scripts

Description

Include Dexie and the package script in the header

Usage

initStore(src = c("browser", "rpkg", "all"), rpkg.api.key)

Arguments

src	scripts to include
rpkg.api.key	API key obtained from rpkg.net to use if src = "rpkg" or "all"

Details

To unlock the "rpkg" or "all" functionality, you'll need to obtain a FREE API key from https://api.rpkg.net
However, before requesting your API key, it's recommended to do an initial deployment of your app. This is because the API key generation process requires you to provide the link to your Shiny app.

Value

Initialize the storage by including scripts necessary for the persistent storage handling

Note

Choices for "src":

"browser" - include only scripts relevant for storing data within browser

"rpkg" - include scripts relevant for storing app views, likes and followers in rpkg.net

"all" - include all scripts

Examples

library(shinyStorePlus)

if (interactive()) {
  ui <- shiny::fluidPage(
    # initialize stores
    initStore(),
    titlePanel("Sample
             shinyStorePlus Init Inputs"),
