Super excited for the new release of #rstats V8 which now also works in WebR by running js/wasm natively in web worker (thanks to @gws.phd). Will release some cool new packages soon to show the potential of WASM in R ✨

PSA for anyone beginning to use #wasm #webR to share R code snippets: We have a new short URL for the webR app: webr.sh!

webR - R in the browser

Interactive R environment running in your browser. Execute R code, create plots, and analyze data without installing anything.

That’s correct, unfortunately. It’s a fundamental limitation of running the Shiny server under Wasm in the user’s browser. Everything is visible in the browser dev tools.

The webR changes haven’t filtered down into Shinylive yet. Once we cut a new release, and Shinylive is updated, we’re hoping curl and friends should work well!

Even ellmer works! Here using a provider that does not require auth: webr.r-wasm.org/latest/#code...

Of course, the usual rules about API keys in webR still apply: *ALL* R source is visible client-side, so *NEVER* publish anything that actually includes any secret keys. This is just a neat demo!

We explain how to make libcurl based applications work in webassembly without changes by tunneling all traffic over a websocket proxy.

Thanks to some joint work with @jeroenooms.bsky.social the latest dev build of webR now supports the {curl} package, along with many other packages that rely on it! 🎉 If you're able to use a WebSocket SOCKS proxy (outside of the browser), you can now use {curl} to make HTTP requests in webR.

As far as I’m concerned, #webr and #shinylive is indistinguishable from magic.

I can’t believe that since first installing #quarto-webr a few hours ago till now, I’ve gotten a relatively complicated #shinyapp exported, deployed, and running serverless.

This is magic. #rstats

I have now also ported the color vision deficiency simulation app to Shiny live. Advantage is this runs entirely in your browser, even though you "upload" the image it never leaves your computer.

Recently I've been working on getting #polars running in #pyodide. This was a fun one, even requiring patches to LLVM's #wasm writer! Everything has now been upstreamed and earlier this week Pyodide v0.27.0 released, including a Wasm build of Polars usable in Pyodide, Shinylive and Quarto Live 🎉

A screenshot of a Pyodide REPL executing Polars code:

import polars as pl
import requests
r = requests.get("https://raw.githubusercontent.com/pola-rs/polars/refs/heads/main/examples/datasets/foods2.csv")
pl.read_csv(r.content).group_by("category").mean()

A screenshot of a Quarto Live code cell executing Polars code:

import polars as pl
import requests
r = requests.get("https://raw.githubusercontent.com/pola-rs/polars/refs/heads/main/examples/datasets/foods2.csv")
pl.read_csv(r.content).group_by("category").mean()

A screenshot of a Shinylive app using Polars code:

from shiny import App, render, ui
import polars as pl
from pathlib import Path

app_ui = ui.page_fluid(
ui.input_select("cyl", "Select Cylinders", choices=["4", "6", "8"]),
ui.output_data_frame("filtered_data")
)

def server(input, output, session):
df = pl.read_csv(Path(__file__).parent / "mtcars.csv")

@output
@render.data_frame
def filtered_data():
return (df
.filter(pl.col("cyl") == int(input.cyl()))
.select(["mpg", "cyl", "hp"]))

app = App(app_ui, server)

R in Production, r-in-production.org, is a new book that will help you put R into production, coupled with (in the near future) new tools to make the process less painful. I'm working on this with @thomasp85.com , @gaborcsardi.bsky.social, and @hfrick.bsky.social.
