Hi Shiny devs!
I'm attempting to start a shiny app using modules.
I have some doubts that make my app not start or crash.
Basically I want a dummy menu with 3 widgets:
- drop down menu with some country names
- button to submit the country name input
this button later on will be connected to create a word file with the name of the country. - button 2 or downloadbutton that will download the word doc created.
I have been reading all about shiny app modules and also I am aware of using moduleServer() for shiny versions 0.15 or above. I'm using 0.15.0.
I know so far I haven't implemented "commented out" the server side of each module.
It doesn't work anyway.
Any pointers on how to get going will be really appreciated.
btw:
In the following link I found a repo which uses two modules:
My question is:
the name of the R file module eg: UploadModule.R
is the same name as the function module server.
uploadModule <- function(input, output, session, ...) {
userFile <- reactive({ …. }) …. }
When calling the module in the app.R
source("uploadModule.R")
….
datafile <- callModule(uploadModule, "datafile")
….
This the bold uploadModule the actual server function from the module named the same?
and
Do we have to have same names?
As mentioned earlier
Any input is really appreciated! I'm sure it will help me to become a better shiny app dev.
Hope you have a great day.
Shiny Regards,
Elia
