Introduction
Shinylive for R enables you to run Shiny applications directly in your web browser—without the need for a traditional Shiny server. By leveraging WebAssembly (WASM) through webR, Shinylive converts your Shiny apps into static web pages that still provide full interactivity. This breakthrough allows you to deploy interactive R apps on any static hosting platform, making sharing and collaboration easier than ever.
What is Shinylive?
Shinylive is an R package that simplifies the process of converting Shiny applications for browser-based execution. Its core functionality includes:
Exporting Shiny Apps:
Converts your Shiny app (e.g., yourapp.R
) into a set of static files (HTML, JavaScript, CSS, and WASM) that run entirely in the browser.Asset Management:
Automatically downloads and caches the necessary Shinylive web assets, ensuring that your app uses the appropriate versions of libraries for WASM-based execution.Serverless Interactivity:
Allows your Shiny app to run without a dedicated server by handling reactive updates and interactivity client-side.
Key Components
Shinylive consists of several interdependent parts:
Shinylive Web Assets:
A library of HTML, CSS, JavaScript, and WASM files that enable Shiny to run in the browser.The
{shinylive}
R Package:
Helps you export your local Shiny application into a directory suitable for static hosting. It also manages the download and caching of web assets.Shinylive Quarto Extension:
Allows you to embed Shinylive applications directly into Quarto documents, making it simple to create interactive, serverless content.(For Python) The shinylive Python Package:
Provides similar functionality for Shiny applications written in Python.
Benefits of Using Shinylive
Serverless Deployment:
Run interactive Shiny apps without a Shiny server. This means you can host your apps on static services like GitHub Pages or Netlify.Simplified Configuration:

R package automates asset management and deployment, reducing the complexity of configuring WASM environments.Enhanced Portability:
Your Shiny app becomes a collection of static files, which can be easily shared or deployed across different platforms.Immediate Interactivity:
Even though the app is served statically, interactivity remains intact, allowing for dynamic, reactive user experiences.
Use Cases
Shinylive is ideal for:
- Educational Content:
Embedding interactive Shiny apps in blog posts or e-learning modules. - Portfolio Projects:
Showcasing Shiny applications on personal websites or GitHub Pages. - Prototyping:
Quickly sharing Shiny prototypes without investing in a dedicated server.
