Beacon Code

1. Problem Statement

When you are already building complex applications with routing, state, and components, you often find that the code is hard to scale to larger projects, test, or adapt to other tasks. You’re not alone — at this level, many feel the need for deeper architecture understanding, development process automation, and code preparation for real-world scenarios.

2. Solution

Beacon Code is a set of materials that helps build a solid foundation for large web applications in pure JavaScript. Here you study architectural patterns, task automation, basic testing, TypeScript fundamentals (as an optional step), web workers, and complete one large comprehensive project with a full development cycle.

3. What's Inside

• Module 1: Architecture of Large Applications — Layer separation (presentation, business logic, data), Clean Architecture adapted for frontend, dependencies & injection, feature-based modules.
• Module 2: TypeScript Basics for JavaScript Developers — Typing variables/functions/interfaces, generics, union/intersection types, gradually adding types to existing JS code.
• Module 3: Automation & Tooling — Simple build setup (ESBuild/Parcel), package.json scripts, pre-commit hooks (husky + lint-staged), basic ESLint + Prettier config.
• Module 4: Testing in Pure JS — Unit tests with Jest-like approach (manual assert), integration tests for components/router, mocking functions & API calls.
• Module 5: Web Workers & Offline Capabilities — Web Worker for heavy computations, Service Worker basics (static file caching), IndexedDB for large local data storage.
• Module 6: Large Comprehensive Project — One big example developed throughout the plan: • Task Management System (Trello-like tool):
  • Multiple boards, lists, cards with drag-and-drop (Pointer Events or HTML Drag & Drop API);
  • Authorization & multi-user simulation (localStorage);
  • Real-time updates (simulation via setInterval + shared state);
  • Filters, sorting, search, tags, deadlines, attachments (simulation);
  • Board export/import to JSON;
  • Dark/light theme with persistence;
  • Full modular structure, typed code (optional TS), tests for key parts.
• Module 7: Deployment & Production Readiness — Static hosting deploy, environment variables, basic optimization (code splitting, tree shaking), error monitoring (console.error + custom logger).

4. Who is this for?

✅ Suitable if you...

• are already building SPA-like apps with routing and state;
• want to understand how large frontend projects are architected;
• are ready to add typing, testing, and automation;
• want to complete one large, structured project from start to deploy.

❌ Not suitable if you...

• have not yet worked with components and client-side routing (better Horizon Code);
• already constantly work with React/Next.js/Vue/Nuxt and are looking for specialization in those stacks.
