Walkthrough

Converts frontend build configuration from CommonJS to ES module syntax and adds the vite-tsconfig-paths plugin as a development dependency to support TypeScript path resolution in Vite.

Poem

🐰 From CommonJS paths to modules so bright,
ESM syntax shines in the light,
TypeScript paths hop along with delight,
Vite config dances—a build-time flight!
Bundled with care, all feels just right.

⚠️ Potential issue | 🟠 Major

vite-tsconfig-paths@^6.1.1 is incompatible with vite@^4.5.0 and is unused.

Two concerns on this new dependency:

  1. Peer-dependency mismatch. vite-tsconfig-paths v6 requires Vite ≥ 5.0.0 (see the v6 release notes: "Vite >= 5.0.0 is now the minimum supported version."). This project still declares "vite": "^4.5.0" on line 60, so installs will emit peer warnings and the plugin is not guaranteed to work at runtime. Either upgrade Vite or pin vite-tsconfig-paths to a v4.x release compatible with Vite 4.

  2. Dead dependency. The plugin is never imported in frontend/vite.config.ts; the @ alias there is still resolved manually via resolve(__dirname, './src'). If the PR's "Fixed Vite alias resolution" goal was to adopt tsconfig paths, the plugin needs to be wired up; otherwise this dep should be removed.

🔧 If the intent is to use tsconfig paths, wire it up in vite.config.ts
 import react from '@vitejs/plugin-react-swc'
 import { dirname, resolve } from 'path'
 import { fileURLToPath } from 'url'
 import { defineConfig } from 'vite'
+import tsconfigPaths from 'vite-tsconfig-paths'

 const __filename = fileURLToPath(import.meta.url)
 const __dirname = dirname(__filename)

 export default defineConfig({
-  plugins: [react()],
+  plugins: [react(), tsconfigPaths()],
   resolve: {
     alias: {
       '@': resolve(__dirname, './src'),
     },
   },
 })

Note: with tsconfigPaths() handling @/* from tsconfig.json, the manual resolve.alias entry becomes redundant and can be removed.

#!/bin/bash
# Confirm the plugin is never actually imported anywhere in the frontend.
rg -nP "vite-tsconfig-paths|tsconfigPaths" -C2

# Confirm the peer-dep range declared by vite-tsconfig-paths@6.1.1.
npm view vite-tsconfig-paths@6.1.1 peerDependencies engines
# And the latest v4.x release that supports Vite 4.

⚠️ Potential issue | 🟡 Minor

Broken JSDoc type annotation — use block-comment form.

// @type {import('tailwindcss').Config} is not a valid JSDoc annotation; TypeScript/editors only recognize the /** ... */ block form, so type checking and intellisense on this config object are silently lost. This was likely an accidental edit during the ESM migration.

🔧 Proposed fix
-// `@type` {import('tailwindcss').Config}
+/** `@type` {import('tailwindcss').Config} */
 export default {
