Portable Shiny app deployment for restricted Windows environments

ShareBridge

Package and distribute Shiny apps to Windows users who have no admin rights, no R installation, and no Shiny Server — just a SharePoint sync.

What is ShareBridge?

ShareBridge is a local deployment framework for packaging Shiny apps into a single self-contained folder that end users can run by double-clicking a file. It is designed for teams that work inside restricted Windows environments where:

• Users do not have admin rights
• Installing R or RStudio on every machine is impractical
• Shiny Server or Posit Connect is not available
• Distribution happens through SharePoint or OneDrive

ShareBridge handles everything: bundling your app code, detecting and installing all package dependencies, copying a stripped portable R, and generating a clean launcher that opens the app in a friendly browser URL like http://sharebridge-myapp.localhost:3670.

Features

📦

Zero admin rights required

Bundles R and all packages inside the deployment folder. Users need nothing pre-installed.

🖥️

Visual Publisher UI

A Shiny-based publisher interface with live build progress, package detection, and saved profiles.

🔍

Automatic dependency detection

Scans your app code for library(), require(), and pkg:: calls. Falls back to regex if renv is not available.

📡

SharePoint & OneDrive distribution

Place the output folder in SharePoint. Users sync it and double-click LaunchApp.hta — nothing else to do.

🌐

Friendly local URLs

Apps open at a human-readable address like sharebridge-myapp.localhost:3670 instead of a raw port number.

📴

Offline repo support

Optionally build a local CRAN mirror inside the deployment so packages install without internet access.

🔬

Health check & test launch

After every build, ShareBridge checks that all required files and packages are present, then lets you test-launch with one click.

💾

Build profiles

Save your publisher settings as named profiles. Reload them in one click for repeatable builds across versions.

Requirements

Side	Requirement
Publisher machine	Windows, R ≥ 4.0, packages: shiny, processx, jsonlite
End user machine	Windows, SharePoint/OneDrive sync (no R, no admin rights needed when portable R is bundled)

---

Quick install

ShareBridge is not a CRAN package — it is a framework folder. To get started:

1. Clone or download the repository
2. Open PublishApp.hta to launch the Publisher UI
3. Point it at your Shiny app and click Build deployment
