# Greenfield TypeScript Stack Opinionated defaults for a new TypeScript service in 2026. Time-stamped: these reflect today's tools and will go stale — adapt them. For a non-trivial new project, run megapowers:brainstorming and megapowers:writing-plans first (if installed) — this skill supplies the stack, not the process. ## Toolchain (pin these) - **pnpm** — package manager (fast, strict, content-addressed store, a real lockfile). Commit `pnpm-lock.yaml`. - **TypeScript, strict** — `"strict": true` plus `"noUncheckedIndexedAccess": true`, `"exactOptionalPropertyTypes": true`, `"noImplicitOverride": true`. Types are a correctness tool; CI fails on a type error (`tsc --noEmit`). - **vitest** — tests (fast, TS-native, ESM-first). - **Biome** (lint + format in one) *or* eslint + prettier — pick one and commit its config. Biome is the fewer-moving-parts default. - **zod** — runtime validation at the boundaries; infer static types from schemas (`z.infer`) so the validator and the type never drift. - Target **ESM** (`"type": "module"`) and a current Node LTS. ## Web: Hono (or Fastify) Hono for a small, fast, edge-portable service; Fastify when you want its plugin ecosystem. Validate every request body/query with zod and derive the handler's types from the schema. ### Middleware order Middleware wraps in the order registered: the **first** registered is the **outermost** (runs first inbound, last outbound). So register the **logger first** so it sees every request —
