webR 0.2: R Packages and Shiny for WebAssembly | George Stagg | Posit

WebR makes it possible to run R code in the browser without the need for an R server to execute the code: the R interpreter runs directly on the user’s machine. But just running R isn't enough, you need the R packages you use every day too.
webR 0.2.0 makes many new packages available (10,324 packages - about 51% of CRAN!) and it's now possible to run Shiny apps under webR, entirely client side.
George Stagg shares how to load packages with webR, know what ones are available, and get started running Shiny apps in the web browser. There’s a demo webR Shiny app too!

I have data stored on a server for my shiny apps. How would webr access that data? It's medium size data.

I have a package that uses rJava to launch a jar and am having trouble converting it to wasm. Do you know if this is possible? I tried using the docker image, installing java in it, and converting rJava first, but get Make sure you have Java Development Kit installed and correctly registered in R. If in doubt, re-run "R CMD javareconf" as root. emconfigure: error: 'sh -c "./configure.orig --build=x86_64-pc-linux-gnu --host=wasm32-unknown-emscripten ac_cv_func_getrandom=no"' failed (returned 1) I tried the suggestion and still can't seem to figure it out.
