160-160: nanoid upgrade looks good

Switching to nanoid@3.3.11 is the correct move given the import updates elsewhere, and there are no API-level breaking changes between 3.3.x patch releases.

Confirm webpack-dev-server v5 side-effects

webpack-dev-server@5.2.2 introduces breaking changes around the dev-middleware API (now adopted in webpackDevServer.config.js). Verify that the scripts/start.js logic that spawns the server doesn’t rely on any removed v4 fields (e.g. devServer.options).

Run to grep for now-removed API usages:

No legacy devServer API usage found in scripts/start.js

All checks confirm that we don’t rely on any removed v4 fields:

• devServer.options is not referenced anywhere in the repo.
• In app/client/scripts/start.js, only devServer.startCallback(...) and devServer.stop() are used—both supported in v5.
• There are no spawn-based invocations of the old CLI.

No further changes required.

Possible non-existent versions – double-check esbuild & vite pins

esbuild is pinned to ^0.25.1 and Storybook bumps vite to ^6.2.7. Those versions do not exist on the public npm registry at the time of writing (latest esbuild ≈ 0.21.x, vite ≈ 5.x). Yarn will fail to resolve them, blocking CI.

---

🏁 Script executed:

#!/usr/bin/env bash
# Sanity-check that the requested versions are published.
for pkg in esbuild@0.25.1 vite@6.2.7; do
  if npm view "$pkg" version >/dev/null 2>&1; then
    echo "✅ $pkg exists"
  else
    echo "❌ $pkg NOT FOUND"
  fi
done

All pinned versions are valid

Quick sanity check confirms that both esbuild@0.25.1 and vite@6.2.7 are published on npm, so CI resolution won’t be blocked.

8-14: Tiny import tweak LGTM

Switching to named import { nanoid } matches the v3 ESM build – no functional impact.

4-5: Consistent nanoid import – all good

Import style now aligns with package upgrade; nothing else to flag.

92-106: server option mapping is correct

Elegant IIFE gets the job done; matches WDS v5 contract for "http" | "https" | {type,options}". Good catch on forwarding custom cert options.
