Architects modern, type-safe TypeScript applications with clean layered structure, ESM defaults, runtime validation, and zero-debt practices.

Modern TypeScript Architecture provides opinionated guidelines and scaffolding patterns for building robust TypeScript projects using Bun or Node 22+. It enforces strict type safety, ESM-native configurations, Zod schema validation, and a strict three-layer architecture (lib, services, adapters) with a 200-line file limit. It also integrates unified LLM proxying via LiteLLM and mandates aggressive dead code removal to prevent technical debt.

Key Features

01ESM-native configuration optimized for Bun and modern Node.js runtimes
02Strict type safety and boundary validation using Zod schemas
03263 GitHub stars
04Clean three-tier layered architecture separating core utilities, business logic, and adapters
05LiteLLM proxy integration for unified multi-provider AI model switching
06Zero backwards compatibility policy to eliminate dead code and maintenance overhead

Use Cases

01Refactoring monolithic TypeScript codebases into modular, maintainable layers
02Scaffolding greenfield backend or full-stack TypeScript projects
03Setting up standardized AI-powered TypeScript apps using LiteLLM
