Running the Brainy Demo

The Brainy interactive demo showcases the library's features in a web browser. Follow these steps to run it:

Prerequisites

Make sure you have Node.js installed (version 23.11.0 or higher)
Ensure the project is built (npm run build:all)

Running the Demo

Option 1: Using the npm script (recommended)

Run the following command from the project root:

npm run demo

This will start an HTTP server and automatically open the demo in your default browser.

Option 2: Manual setup

Start an HTTP server in the project root:

npx http-server

Open your browser and navigate to: http://localhost:8080/demo/index.html

Troubleshooting

If you see the error "Could not load Brainy library. Please ensure the project is built and served over HTTP", check the following:

Make sure you've built the project with npm run build:all
Ensure you're accessing the demo through HTTP (not by opening the file directly)
Check your browser's console for additional error messages

If issues persist, try clearing your browser cache or using a private/incognito window.

Build Process

The Brainy library uses a two-step build process:

npm run build - Compiles TypeScript files to JavaScript (used for Node.js environments)
npm run build:browser - Creates a browser-compatible bundle using Rollup

You can run both steps together with:

npm run build:all

The browser bundle is created from src/unified.ts, which provides environment detection and adapts to browser, Node.js, or serverless environments. This unified approach ensures that the library works correctly across all environments.
