# excalidrawr

Quick experiment to wrap [Excalidraw](https://excalidraw.com/) for use in R.

## Installation

``` r

remotes::install_github("timelyportfolio/excalidrawr")

```

## Example

Currently, the package does very little except open an `Excalidraw` instance ready for your creative adventures.

``` r

library(excalidrawr)

excalidraw()

```

We can also use the `onChange` prop to communicate with Shiny.

``` r

library(htmltools)

library(shiny)

library(excalidrawr)

ui <- excalidraw(

  onChange = htmlwidgets::JS(

"

function(elements, state) {

  if(Shiny && Shiny.setInputValue) {

    Shiny.setInputValue('excal1', {elements})

  }

}

"

  ),

  elementId = "excal1"

)

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

  draw <- reactive({

    input$excal1

  })

  draw_d <- debounce(draw, 1000)

  observe({

    str(draw_d())

  })

}

shinyApp(ui, server)

```
