Modern TypeScript project architecture guide for 2025. Use when creating new TS projects, setting up configurations, or designing project structure. Covers tech stack selection, layered architecture, and best practices.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TypeScript Project Architecture ## Core Principles - **Type safety first** — Strict mode, no `any`, Zod for runtime validation - **ESM native** — ES Modules by default, Node 22+ / Bun - **Layered architecture** — Separate lib/services/adapters - **200-line limit** — No file exceeds 200 lines (see elegant-architecture skill) - **Test reality** — Vitest/Bun test, minimal mocks - **No backwards compatibility** — Delete, don't deprecate. Change directly, no shims - **LiteLLM for LLM APIs** — Use LiteLLM proxy for all LLM integrations, unless specific SDK required ## Gotchas - Bun, Zod, directory layout and LiteLLM choices are activation observations, not proof of task success. Check valid inputs, invalid inputs, state changes and the actual error contract. - A template can pass service tests and still fail `typecheck`; the maintained template's `noUnusedLocals` caught an unused configuration helper in the October 2026 case. Run both. - `latest` dependency declarations do not pin a reproduced run. Keep the generated lockfile with its evidence and record actual installed versions. Don't claim another runtime passed. …

How to install
mdr add majiayu000/spellbook/typescript-project@sha256:1437727c9f0a5ad3The line at the top of this page pins the label git:20261007.31bf196, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
