tmu 9e5522c131 🚚 Home test helpers behind #test-utils/*
src/util/__tests__/ holds shared test helpers, reached from anywhere
in the source tree as `#test-utils/<name>.ts` through
package.json#imports. A bare `~/…` is not a valid imports key — Node
requires `#` — and a direction-free specifier keeps
import/no-relative-parent-imports from ever firing. The `__tests__`
folder name is the pattern tsconfig.build.json already excludes, so
helpers can never ship. Lint scoping: import/no-nodejs-modules off for
the folder (the probe spawns a language server) and
typescript/promise-function-async off to match its promise-returning
style. The LSP probe moves in from scripts/; a smoke test pins the
specifier's resolution and typing without starting a server.

tiny-pattern-ts

Pattern matching for TypeScript/ESM environments (F#-style, not regex).

Description

tiny-pattern-ts brings F#-style pattern matching to TypeScript. Patterns are ordinary objects whose matches method is a TypeScript type guard, so narrowing composes the way any other guard does. It is deliberately not a regex engine and not a macro: there is no transpiler and no DSL to learn, and the type-level contract is the feature — see development/library.md for the design decisions and the known limitations.

Requirements

  • Node.js >= 26 (engines field; pinned via .node-version).
  • TypeScript >= 5.0 to consume the published declarations. The emitted .d.ts use const type parameters (TS 5.0) and keep their relative .ts specifiers; both resolve on TS >= 5.0 in node10 / node16 / nodenext / bundler.
  • The package is ESM-only (no CommonJS shim).
