# shinyStorePlus R package 
### FOUR MAIN FEATURES:
- [x] In-browser storage for Shiny persistent, synchronized data from the inputs using IndexedDB.
- [x] Transfer browser link parameters to Shiny input or output values.
- [x] Execute shiny::observe once across multiple browser sessions e.g show welcome message only once to a user
- [x] __Store shiny app visitor views, likes and followers using api.rpkg.net !NEW__
Note: As of version 1.4, shinyStorePlus now allows storage of visitor views, likes and followers
Note: As of version 1.5, shinyStorePlus now use of "*" in the __dyn.inputs__ of setupStorage(). [check](inst/example/dynamicInput/app2.R)

There has been tremendous contribution from the R community on the topic of storing Shiny data and re-using them within an application. The current solutions include Dropbox, Amazon s3, Googlesheets, SQLite, MongoDB and so on. However, a problem with these methods is that it takes a number of steps in order to correctly program your Shiny application for them. More so, the owner of the accounts may need to consistently monitor the storage accounts to ensure that it is not expire or that the data storage is not exhausted.
__So let's face it. When you develop a shiny app that allows a user to change inputs and see the results immediately, guess what the user is itching to have?? The ability to change the inputs and when they refresh or reopen the shiny app at a later time, still see the inputs they previously entered. Well, shinyStorePlus R package gives that!__
----------------------------------------------------------------------------------------------
As of __version 0.8__ , you are also able to transfer the parameters in a browser link to Shiny inputs and outputs. e.g extracting the value of name from __http://127.0.0.1:6692/?data=pressure&name=obinna&num=50&outt=wowowow__. See [link](https://shinystoreplus.obi.obianom.com/articles/shinystoreplus_v08.html)

selectInput("sel_color", "Color (should be stored):", choices = c("", "green", "blue", "red", "yellow", "cyan"), selected = ""),
tags$h2(id="dyn1","Dynamic Input Selected By Full ID name"),
hr(),tags$p(tags$i("Like or Follow and Refresh the page - the values are saved and the views are incremented."))
)
server <- function(input, output, session) {
insertUI( selector = "#dyn1", where = "afterEnd", ui = textInput("dynamicinput1", "Dynamic input","test" ) )
# set up views, likes and follows, leave as NULL if you don't need tracking for either
# in this case, we leave followID as NULL since we don't need to use that
setupRPKG(viewsID = "viewsshow", likesID = "liket", followID = "followt")
# setup for in browser tracking for all inputs
# setupStorage(appId = "shinestz12", inputs = TRUE, session = session)
# setup for in browser tracking for specific inputs
# setupStorage(appId = "shinesty12", inputs = c("sel_not0","sel_color"), session = session)
# setup for in browser tracking for dynamic inputs
setupStorage(appId = "shinestx12", dyn.inputs = list("dynamicinput1"), session = session)
}
shinyApp(ui = ui, server = server)
