From 52a43d51d4e57e2562be819739d2d8a5d3584550 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Tue, 5 Aug 2025 16:09:30 -0700 Subject: [PATCH] refactor: simplify build system and improve model loading flexibility - Remove Rollup bundling in favor of direct TypeScript compilation - Move from bundled models to dynamic model loading with configurable paths - Add Docker deployment examples and documentation - Implement robust model loader with fallback mechanisms - Update storage adapters for better cross-environment compatibility - Add comprehensive tests for model loading and package installation - Simplify package.json scripts and remove complex build configurations - Clean up deprecated demo files and old bundling scripts BREAKING CHANGE: Models are no longer bundled with the package. They are now loaded dynamically from CDN or custom paths. --- .github/workflows/deploy-demo.yml | 11 +- .gitignore | 1 + README.md | 266 +- demo/CNAME | 1 - demo/brainy-angular-demo/README.md | 59 - demo/index.html | 5361 ----------------- demo/test-browser-worker.html | 104 -

Interactive Brainy Explorer

-

This interactive demo guides you through Brainy's features step by step, from basic operations to advanced - capabilities.

- - -
-

Step 1: Getting Started with Brainy

-

Let's start by initializing the database and exploring basic operations.

- -
- - - - - -
- -
- Database not initialized. Click "Initialize Database" to start. -
- -
-
- -
-
-
- Database visualization will appear here after initialization -
-
-
-
- - -
-

Step 2: Semantic Search

-

Search your data using vector embeddings for semantic understanding.

- - -
-
-
-
- - - -
- -
- - - -
-
-
- -
-
- -
-
- - -
-
-
- -

- Try searching for topics in the sample data like "machine learning", "AI ethics", "computer vision", "robotics", "quantum computing", - "cybersecurity", or specific concepts like "large language models", "federated learning", "explainable AI", "climate science", etc. -

- -
-
- Search results will appear here... -
-
- -
-
- - - -
-
-
- Search results visualization -
-
-
-
- - -
-

Step 3: Adding Entities (Nouns)

-

Now that your database is initialized, let's add some entities (nouns) to it.

- -
- - -
- -
- - -
- -
- - -
- -
- - -
- -
- - -
- -
- - -
- -
- Entity operations will appear here... -
-
- - -
-

Step 4: Creating Relationships (Verbs)

-

Connect your entities with meaningful relationships to build a knowledge graph.

- -
- - - -
- -
- - -
- -
- - -
- -
- - -
- -
- - -
-
- - -
-

Step 5: Advanced Features

-

Explore Brainy's advanced capabilities for more complex use cases.

- -
-
-

๐Ÿ” Vector Search

-

Explore how HNSW makes semantic search fast and efficient.

- -
- -

Step 6: Command Line Interface

-

Try Brainy's CLI commands for scripting and automation.

- -
-
-
- brainy$ - -
-
-
- -
- - - - - -
- -
- Common Commands:
- brainy init - Initialize a new database
- brainy add <data> - Add data to the database
- brainy search <query> - Search for entities
- brainy relate <from> <to> - Create relationships
- brainy status - Show database status
- brainy help - Show all commands -
-
-
- - -
-

๐Ÿ Quick Start

- -
-
-

Node.js Environment

- 
-import { BrainyData, NounType, VerbType } from '@soulcraft/brainy'
-
-// Create and initialize the database
-const db = new BrainyData()
-await db.init()
-
-// Add data (automatically converted to vectors)
-const catId = await db.add("Cats are independent pets", {
-    noun: NounType.Thing,
-    category: 'animal'
-})
-
-const dogId = await db.add("Dogs are loyal companions", {
-    noun: NounType.Thing,
-    category: 'animal'
-})
-
-// Search for similar items
-const results = await db.searchText("feline pets", 2)
-console.log(results)
-// Returns items similar to "feline pets" with similarity scores
-
-// Add a relationship between items
-await db.addVerb(catId, dogId, {
-    verb: VerbType.RelatedTo,
-    description: 'Both are common household pets'
-})
-
-
- -
-

Browser Environment

-

Brainy uses a unified build that automatically adapts to your environment:

- -

Option 1: Standard Import

- 
-// Standard import - automatically adapts to any environment
-import { BrainyData, NounType, VerbType } from '@soulcraft/brainy'
-
-// Use the same API as in Node.js
-const db = new BrainyData()
-await db.init()
-// ...
-
- -

Option 2: Using a script tag in HTML

- 
-<script type="module">
-  // Use local files instead of CDN
-  // For GitHub Pages, use relative path: './dist/unified.js'
-  // For local development, use absolute path: '/dist/unified.js'
-  // This import is replaced by the dynamic import below
-
-  // Or minified version
-  // import { BrainyData, NounType, VerbType } from '/dist/unified.min.js'
-
-  const db = new BrainyData()
-  await db.init()
-  // ...
-</script>
-
-

Modern bundlers like Webpack, Rollup and Vite will automatically use the unified build which adapts to any - environment.
