ts transformer mangle notes

SPEC — ts-transformer-properties-rename

This document specifies the behavior of the transformer so it can be re-implemented (e.g. on top of ts-morph) without re-deriving the rules from the test fixtures. It is a behavioral spec, not an architectural one — it says what must happen for any given input, not how the current implementation does it.

The reference implementation lives in src/transformer.ts, src/exports-symbol-tree.ts, and src/typescript-helpers.ts. The fixtures under tests/test-cases/ are the ground truth — anything below that disagrees with a fixture is wrong.

Advanced example for manually managing subscriptions in an async-safe way using hooks
import React, { useMemo } from "react";
import useSubscription from "./useSubscription";
// In this example, "source" is an event dispatcher (e.g. an HTMLInputElement)
// but it could be anything that emits an event and has a readable current value.
function Example({ source }) {
// In order to avoid removing and re-adding subscriptions each time this hook is called,
// the parameters passed to this hook should be memoized.
