macOS ships bash 3.2 (no wait -n): poll with kill -0 instead. npm spawns vite as a grandchild, so cleanup now recurses pgrep -P to reap the whole subtree — Ctrl-C frees both :8000 and :5173 cleanly. Verified clean-checkout -> dev.sh -> empty self-migrated Postgres -> /healthz 200, and trap teardown. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Local bring-up for ecomm (SD-0001 PUC-10). From a clean checkout this:
|
|
# 1. starts the dev Postgres container and waits for it to be healthy (owns its
|
|
# lifecycle — Docker is the one prerequisite, docs/BOOTSTRAP.md);
|
|
# 2. ensures the backend venv + deps and the frontend node_modules;
|
|
# 3. runs the FastAPI backend (:8000, self-migrating an empty DB) and the Vite dev
|
|
# server (:5173, proxying /api -> :8000) together.
|
|
# Ctrl-C stops both processes; the container keeps running (stop it with
|
|
# `docker compose down`, or `docker compose down -v` to reset to empty).
