About

Maintained by Barret SchloerkeCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

Server-side plumbing for the 'ui.tsx' pattern in 'Shiny': the user interface is defined in a client 'React' (https://react.dev/) bundle, and the 'Shiny' server contains only reactive computation. Provides page builders that discover and serve the client bundle, a render function that publishes any JSON-serializable value to the client, and custom messages to 'React' components. Ships no user interface components, so the app author owns the whole front end. The 'React' runtime and the client hooks are bundled, so no JavaScript build step is required to get started.

Changes in 0.1.0

Initial CRAN release. shinyreact is the server-side plumbing for the ui.tsx pattern: the UI is a React client you own, and the Shiny server contains only reactive computation. It ships no UI components.
Dependencies of traditional Shiny outputs hosted inside a React tree are discovered automatically and pushed to the client after each flush, so the ShinyOutput component works with zero configuration.
Bookmark restore values reach the client through the #shinyreact-config script tag, and the client asserts the wire-protocol major version at boot.
page_react() serves www/ui.js (and www/ui.css, if present) as the whole page, with no HTML file required. page_react_html() serves a complete index.html that you own, page_bare() builds a page with no Bootstrap, and page_react_dep() wraps an app's own bundle as an htmlDependency() versioned by its mtime.

reactive_output() publishes any JSON-serializable value to the client's useShinyOutputValue() hook, with no UI placeholder.
send_message() sends a custom message to the client's useShinyMessageHandler() hook, namespaced to the current module.
shinyreact.default and shinyreact.asis input handlers give R and Python the same view of the JSON a useShinyInput() hook sends: records stay lists, [] stays list(), and nested arrays keep their shape.
wire_tap() reads the websocket payloads a shinytest2 AppDriver recorded, so tests can assert the exact inputs, outputs, and messages that crossed the wire.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("shinyreact", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("posit-dev/shinyreact")

Development version from posit-dev/shinyreact. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-shinyreact

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-shinyreact

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-shinyreact

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
