server.js (1)

1-1: Clarify the entrypoint; avoid duplicate servers

There’s already a backend/server.js in the repo; this top-level server.js only logs and may confuse deploy/start scripts. Either remove it or delegate to the real server file.

Apply if you intend this to bootstrap the backend:

- console.log("Node is working!");
+ // Delegate to the real backend server
+ require("./backend/server");

backend/config/db.js (1)

10-13: Don’t exit the process inside a library helper

process.exit(1) here will kill tests and dev watchers. Let the caller decide how to handle failures.

-  } catch (err) {
-    console.error(err.message);
-    process.exit(1);
-  }
+  } catch (err) {
+    console.error('MongoDB connection error:', err);
+    throw err;
+  }

github-tracker-auth/package.json (1)

12-18: Trim unused deps or wire them up

This package doesn’t use passport or express-session. Remove them or implement session-based flows here.

github-tracker-auth/index.js (4)

23-24: Return 201 for successful registration

Created is the more appropriate status.

-  res.json({ message: "User registered successfully 🚀" });
+  res.status(201).json({ message: "User registered successfully 🚀" });

---

41-48: Harden Authorization header parsing

Be strict about the Bearer scheme to avoid accidental parsing of malformed headers.

 app.get("/profile", (req, res) => {
   const authHeader = req.headers["authorization"];
   if (!authHeader) return res.status(401).json({ message: "No token provided" });
 
-  const token = authHeader.split(" ")[1];
+  if (!/^Bearer\s+/i.test(authHeader)) {
+    return res.status(401).json({ message: "Invalid auth scheme" });
+  }
+  const token = authHeader.split(" ")[1];
   jwt.verify(token, process.env.JWT_SECRET, (err, decoded) => {
     if (err) return res.status(403).json({ message: "Invalid token" });

---

54-54: Avoid fixed port; export app for tests

Prevents port collisions and makes the app importable.

-app.listen(3000, () => console.log("Server is running 🚀"));
+const PORT = process.env.PORT || 3000;
+if (require.main === module) {
+  app.listen(PORT, () => console.log(`Auth server listening on ${PORT} 🚀`));
+}
+module.exports = app;

---

8-8: Confirm this in-memory store is dev-only

users = [] is ephemeral; ensure the main app doesn’t depend on this service in production.

backend/routes/auth.js (1)

18-29: Add brute-force protection on login

Add basic rate limiting on /login (and optionally /signup) to mitigate credential stuffing.

Example (outside this file’s hunk):

// near router creation
const rateLimit = require('express-rate-limit');
const loginLimiter = rateLimit({ windowMs: 15 * 60 * 1000, max: 20, standardHeaders: true, legacyHeaders: false });
router.post('/login', loginLimiter, /* existing handler */);

💡 Knowledge Base configuration:

• MCP integration is disabled by default for public repositories
• Jira integration is disabled by default for public repositories
• Linear integration is disabled by default for public repositories

You can enable these sources in your CodeRabbit configuration.

client/vite.config.js (1)

5-7: Dev DX: add proxy to backend for cookie-based auth (withCredentials).

Proxying /api to your backend avoids CORS pain and forwards cookies during dev.

-import { defineConfig } from 'vite'
+import { defineConfig, loadEnv } from 'vite'
 import react from '@vitejs/plugin-react'
 
 // https://vite.dev/config/
-export default defineConfig({
-  plugins: [react()],
-})
+export default defineConfig(({ mode }) => {
+  const env = loadEnv(mode, process.cwd(), '');
+  return {
+    plugins: [react()],
+    server: {
+      proxy: {
+        '/api': {
+          target: env.VITE_BACKEND_URL || 'http://localhost:3000',
+          changeOrigin: true,
+          secure: false,
+        }
+      }
+    }
+  }
+})

client/.gitignore (1)

15-24: Ignore env files to avoid leaking secrets.

Add typical Vite env patterns; keep .env.example tracked.

 # Editor directories and files
 .vscode/*
 !.vscode/extensions.json
 .idea
 .DS_Store
 *.suo
 *.ntvs*
 *.njsproj
 *.sln
 *.sw?
+#
+# Env files
+.env
+.env.local
+.env.development.local
+.env.test.local
+.env.production.local
+.env.*.local
+!.env.example

client/package.json (1)

12-28: Toolchain compatibility confirmed.
• @vitejs/plugin-react v5.x (latest 5.0.2) peer-depends on Vite ^4.2.0 || ^5.0.0 || ^6.0.0 || ^7.0.0, so Vite 7 is supported.
• react-router-dom 7.8.2 peer-depends on React >=18 and React-DOM >=18, so React 19/React-DOM 19 satisfy it.

Consider pinning Node for consistent ESM/Vite support (optional):

   "type": "module",
+  "engines": {
+    "node": ">=18.18.0"
+  },

middleware/auth.js (1)

1-13: Unify response shape (message vs msg) and status codes.

Elsewhere you use message. Align for consistency.

 export function ensureAuthenticated(req, res, next) {
   if (req.isAuthenticated()) {
     return next();
   }
-  res.status(401).json({ msg: 'You must be logged in to access this route' });
+  res.status(401).json({ message: 'You must be logged in to access this route' });
 }
 
 export function forwardAuthenticated(req, res, next) {
   if (!req.isAuthenticated()) {
     return next();
   }
-  res.status(403).json({ msg: 'You are already logged in' });
+  res.status(403).json({ message: 'You are already logged in' });
 }

src/Signup.jsx (1)

5-29: Duplicate Signup implementations (TSX vs JSX) risk divergence.

There’s also src/pages/Signup/Signup.tsx using username/email/password and different API shape. Keep one source of truth.

Would you like me to generate a migration diff to consolidate on the TSX page and remove this JSX file?

server.js (2)

38-41: Remove deprecated Mongoose options (v6+).

useNewUrlParser and useUnifiedTopology are defaults and can be dropped.

---

21-27: Behind a reverse proxy, set trust proxy for secure cookies.

Apply:

 const app = express();
+if (process.env.NODE_ENV === 'production') app.set('trust proxy', 1);

src/dashboard.jsx (1)

5-5: Prop usage nit: 'user' isn’t referenced.

Remove or use it to personalize the message.

src/Routes/auth.js (2)

23-26: Handle duplicate key errors from MongoDB

Guard against race conditions when two signups use the same username.

Apply:

-  } catch (err) {
-    res.status(500).json({ error: err.message });
-  }
+  } catch (err) {
+    if (err?.code === 11000) {
+      return res.status(400).json({ message: 'Username already exists' });
+    }
+    res.status(500).json({ message: 'Error creating user' });
+  }

---

10-20: Add basic input validation

Enforce username format and password strength (length/min classes), ideally via express-validator/Joi, before hashing/saving.

client/src/main.jsx (1)

6-10: Guard against missing #root

Avoid runtime errors if the root element is absent.

Apply:

-createRoot(document.getElementById('root')).render(
+const rootEl = document.getElementById('root');
+if (!rootEl) throw new Error('#root not found');
+createRoot(rootEl).render(

src/login.jsx (1)

5-19: Duplicate Login implementations exist (this and src/pages/Login/Login.tsx)

Keep one source of truth to avoid drift.

client/eslint.config.js (1)

11-15: Replace deprecated React Hooks preset and include React/a11y configs

• Swap
  reactHooks.configs['recommended-latest'] → reactHooks.configs.recommended
  (recommended-latest is deprecated as of v5.2.0; the flat-config recommended is now the default) (npmjs.com, app.semanticdiff.com)
• Add React and a11y shareable configs to the extends array:
  react.configs.flat.recommended and jsxA11y.flatConfigs.recommended (app.unpkg.com, github.com)

server/server.js (1)

8-8: Consider removing redundant body-parser dependency.

Express 4.16+ includes built-in JSON and URL-encoded body parsing. The body-parser package is redundant and can be replaced with express.json() and express.urlencoded().

-import bodyParser from 'body-parser';

-app.use(bodyParser.json());
-app.use(bodyParser.urlencoded({ extended: true }));
+app.use(express.json());
+app.use(express.urlencoded({ extended: true }));

package.json (1)

14-14: Remove redundant body-parser dependency.

The body-parser package is redundant since Express 4.16+ includes built-in JSON and URL-encoded parsing middleware.

-    "body-parser": "^1.20.2",
