trackerscript.js

+  const transactionType = type.value || 'transaction';
+  showNotification(`${transactionType.charAt(0).toUpperCase() + transactionType.slice(1)} added successfully!`, 'success');


The success notification is attempting to use type.value after the form fields have been cleared on line 318. This will always result in an empty string being passed to the notification function, causing the message to be "Transaction added successfully!" instead of the intended "Income added successfully!" or "Expense added successfully!". Store the type.value in a variable before clearing the form fields.

trackerscript.js

+          <button class="goal-delete" onclick="deleteGoal(${index})">
+            <i class="fas fa-trash"></i>
+          </button>


The inline onclick handler uses deleteGoal with an index parameter. If the goals array is modified (e.g., a goal is deleted) while the user is viewing the goals, the indices will shift but the rendered HTML won't update immediately. This can cause the wrong goal to be deleted. Use event delegation or store the goal ID instead of the index for safer deletion.

+          <button class="goal-delete" onclick="deleteGoal(${index})">

+          <div class="progress-text">
+            <span>₹${goal.current.toFixed(2)} / ₹${goal.amount.toFixed(2)}</span>
+            <span>${progress.toFixed(1)}%</span>
+          </div>
+        </div>
+        <div class="goal-details">

+            <span>${daysRemaining > 0 ? `${daysRemaining} days left` : 'Deadline passed'}</span>

+          </div>
+        </div>
+        ${goal.description ? `<p class="goal-description">${goal.description}</p>` : ''}


The goal.title and goal.description are directly interpolated into HTML without sanitization. This creates a Cross-Site Scripting (XSS) vulnerability. If a user enters HTML or JavaScript code in the title or description, it will be executed when the goals are displayed. Use textContent or sanitize the input before rendering.

trackerscript.js

+
+    const title = document.getElementById('goal-title').value;
+    const amount = parseFloat(document.getElementById('goal-amount').value);
+    const current = parseFloat(document.getElementById('goal-current').value) || 0;
+    const deadline = document.getElementById('goal-deadline').value;
+    const description = document.getElementById('goal-description').value;
+
+    if (!title || !amount || !deadline) {
+      showNotification('Please fill in all required fields', 'error');
+      return;
+    }


The goal validation only checks for presence of required fields but doesn't validate the values. The amount and current values should be checked to ensure they're positive numbers, and the deadline should be validated to ensure it's a valid date (and ideally in the future). Additionally, there's no maximum length validation for title and description which could lead to display issues.

Suggested change

const title = document.getElementById('goal-title').value;

const amount = parseFloat(document.getElementById('goal-amount').value);

const current = parseFloat(document.getElementById('goal-current').value) || 0;

const deadline = document.getElementById('goal-deadline').value;

const description = document.getElementById('goal-description').value;

if (!title || !amount || !deadline) {

showNotification('Please fill in all required fields', 'error');

return;

}

const MAX_TITLE_LENGTH = 100;

const MAX_DESCRIPTION_LENGTH = 1000;

const rawTitle = document.getElementById('goal-title').value;

const rawAmount = document.getElementById('goal-amount').value;

const rawCurrent = document.getElementById('goal-current').value;

const rawDeadline = document.getElementById('goal-deadline').value;

const rawDescription = document.getElementById('goal-description').value;

const title = rawTitle.trim();

const amount = parseFloat(rawAmount);

const current = rawCurrent === '' ? 0 : parseFloat(rawCurrent);

const deadline = rawDeadline.trim();

const description = rawDescription.trim();

// Basic required field validation

if (!title || !deadline) {

showNotification('Please fill in all required fields', 'error');

return;

}

// Numeric validation for amount and current

if (Number.isNaN(amount) || amount <= 0) {

showNotification('Goal amount must be a positive number', 'error');

return;

}

if (Number.isNaN(current) || current < 0) {

showNotification('Current savings must be a number greater than or equal to 0', 'error');

return;

}

if (current > amount) {

showNotification('Current savings cannot exceed the goal amount', 'error');

return;

}

// Deadline validation: valid date and in the future

const deadlineDate = new Date(deadline);

if (Number.isNaN(deadlineDate.getTime())) {

showNotification('Please enter a valid deadline date', 'error');

return;

}

// Consider the entire deadline day as valid

const endOfDeadlineDay = new Date(deadlineDate.getTime());

endOfDeadlineDay.setHours(23, 59, 59, 999);

const now = new Date();

if (endOfDeadlineDay <= now) {

showNotification('Deadline must be a future date', 'error');

return;

}

// Length validation for title and description

if (title.length > MAX_TITLE_LENGTH) {

showNotification(`Title must be at most ${MAX_TITLE_LENGTH} characters`, 'error');

return;

}

if (description.length > MAX_DESCRIPTION_LENGTH) {

showNotification(`Description must be at most ${MAX_DESCRIPTION_LENGTH} characters`, 'error');

return;

}

trackerscript.js

+    link.href = URL.createObjectURL(blob);
+    link.download = `expenseflow-backup-${new Date().toISOString().split('T')[0]}.json`;
+    link.click();


The export data functionality doesn't clean up the created object URL after the download is triggered. This can lead to memory leaks, especially if users export data multiple times in a session. Add URL.revokeObjectURL(link.href) after triggering the click, or use a timeout to clean it up.

Suggested change

link.href = URL.createObjectURL(blob);

link.download = `expenseflow-backup-${new Date().toISOString().split('T')[0]}.json`;

link.click();

const objectUrl = URL.createObjectURL(blob);

link.href = objectUrl;

link.download = `expenseflow-backup-${new Date().toISOString().split('T')[0]}.json`;

link.click();

URL.revokeObjectURL(objectUrl);

expensetracker.css

+  font-size: 0.95rem;
+  letter-spacing: 0.3px;
  padding: 0.5rem 1rem;
  border-radius: 0.5rem;
  transition: all 0.3s ease;
  position: relative;
+  text-transform: uppercase;
+  font-size: 0.85rem;


The font-size property is defined twice for .nav-link (lines 124 and 131), with different values (0.95rem and 0.85rem). The second declaration will override the first, making line 124 redundant. Remove the duplicate font-size declaration on line 124.

trackerscript.js

+      setTimeout(() => updateAnalytics(), 100);
+    }
+
+    // Update goals if navigating to goals section
+    if (sectionId === 'goals') {
+      setTimeout(() => displayGoals(), 100);


The showSection function uses setTimeout with a hardcoded 100ms delay to update analytics and goals. This arbitrary delay can lead to race conditions or unnecessary waiting. Consider using a callback or Promise-based approach, or call these functions directly since they should be safe to execute immediately.

Suggested change

setTimeout(() => updateAnalytics(), 100);

}

// Update goals if navigating to goals section

if (sectionId === 'goals') {

setTimeout(() => displayGoals(), 100);

updateAnalytics();

}

// Update goals if navigating to goals section

if (sectionId === 'goals') {

displayGoals();

trackerscript.js

+    // Get the base path for service worker registration
+    const basePath = window.location.pathname.split('/').slice(0, -1).join('/') || '.';
+    const swPath = basePath === '.' ? './sw.js' : `${basePath}/sw.js`;
+
+    navigator.serviceWorker.register(swPath, { scope: basePath === '.' ? './' : basePath })


The service worker registration scope configuration may cause issues. When basePath is not '.', you're setting the scope to the base path directory but registering at ${basePath}/sw.js. This is unnecessarily complex and could fail if the page is accessed at different URL depths. Consider using a simpler approach with relative paths only (e.g., always use './sw.js' with scope './') since the manifest.json already uses relative paths.

trackerscript.js

+  // Hook into transaction updates to refresh analytics
+  const originalUpdateLocalStorage = updateLocalStorage;
+  updateLocalStorage = function() {
+    originalUpdateLocalStorage();
+    if (document.getElementById('analytics') && document.getElementById('analytics').classList.contains('active')) {
+      updateAnalytics();
+    }
+  };


The function is reassigning the global updateLocalStorage function by wrapping the original. This is a fragile pattern that could cause issues if updateLocalStorage is called before DOMContentLoaded fires, or if other code also tries to wrap this function. Consider using event dispatching or a callback system instead of function wrapping.

Suggested change

// Hook into transaction updates to refresh analytics

const originalUpdateLocalStorage = updateLocalStorage;

updateLocalStorage = function() {

originalUpdateLocalStorage();

if (document.getElementById('analytics') && document.getElementById('analytics').classList.contains('active')) {

updateAnalytics();

}

};

// Observe transaction list changes to refresh analytics

if (typeof MutationObserver !== 'undefined' && list) {

const analyticsObserver = new MutationObserver(() => {

const analyticsSection = document.getElementById('analytics');

if (analyticsSection && analyticsSection.classList.contains('active')) {

updateAnalytics();

}

});

analyticsObserver.observe(list, { childList: true, subtree: false });

}

  'https://fonts.googleapis.com/css2?family=Inter:wght@300;400;500;600;700&display=swap',


The urlsToCache array includes a Google Fonts URL but the HTML file now loads three different font families (Poppins, Space Grotesk, and Inter). The cached fonts URL only includes Inter, which means the other fonts won't be cached and will fail to load when offline. Update the cached URL to match the one in index.html.
