name	typescript-7
description	Use TypeScript 7 (native Go compiler / tsgo) for typecheck and CI in this monorepo. Trigger when: TypeScript 7, tsgo, native-preview, tsc7, parallel checkers, side-by-side with TypeScript 6 API, eslint peer typescript, or migrating typecheck off tsc6.

TypeScript 7 (native) — OpenClaw / Logan

What TS 7 is

• Native Go port of the TypeScript compiler and language tooling (Project Corsa).
• Typical 8–12× full-build speedups vs TypeScript 6; lower memory.
• No stable programmatic API in 7.0 (expected in 7.1). Tools that import "typescript" (eslint, Volar, Next.js plugin, etc.) still need TypeScript 6 side-by-side.

Official: Announcing TypeScript 7.0

This repo’s layout (authoritative)

Package	Role
typescript (currently 6.x)	JS API for eslint / programmatic tools
@typescript/native-preview	TS 7 tsgo binary (nightly/dev builds)
scripts/run-tsgo.mjs	Policy wrapper: locks, sparse guards, local heavy-check
pnpm tsgo:core / tsgo:all / …	Project-scoped typecheck entrypoints

Prefer node scripts/run-tsgo.mjs … or pnpm tsgo:* over raw npx tsc for monorepo typecheck.

When implementing features

1. Write normal TypeScript — language surface is TS 6-compatible; do not rely on 7.0-only type-level UTF-16 quirks without checking.
