Browser API Migration Status for Edge Extension

✅ Migration Complete!

All Edge extension files have been successfully migrated:

APIs Wrapped (10 total)

• storage, tabs, runtime, contextMenus, alarms, action, commands, identity, notifications, scripting

Files Updated (25+)

• All lib/ files (storage, sync, config, ads, api)
• All popup/modules/ files (storage, theming, user-engagement, settings, editor, notes, onboarding-tooltips)
• Main files (popup.js, background.js, content.js)
• HTML files (onboarding.html)

Browser-Specific Updates

• ✅ All chrome.* API calls → browserAPI.*
• ✅ All chrome:// URLs → edge:// URLs (Edge-specific)
• ✅ Keyboard shortcuts link → edge://extensions/shortcuts
• ✅ Error messages updated for Edge

Ready for Testing

Load extension-edge/ in Edge at edge://extensions/ (enable Developer mode)

Remaining Files to Update

The Edge extension uses the same chrome.* namespace as Chrome, but the browserAPI wrapper provides:

• Promise-based API for consistency with Firefox
• Future-proofing for any Edge-specific differences
• Unified codebase across all three browsers

All files have been successfully migrated to use browserAPI.* instead of chrome.*.

Migration Pattern

All Chrome API calls should be replaced following this pattern:

Storage API

// Before
await chrome.storage.local.get(['key'])
await chrome.storage.local.set({ key: value })
await chrome.storage.local.remove(['key'])

// After
await browserAPI.storage.local.get(['key'])
await browserAPI.storage.local.set({ key: value })
await browserAPI.storage.local.remove(['key'])

Tabs API

// Before
chrome.tabs.create({ url })
chrome.tabs.query(queryInfo)

// After
await browserAPI.tabs.create({ url })
await browserAPI.tabs.query(queryInfo)

Runtime API

// Before
chrome.runtime.sendMessage(message)
chrome.runtime.getURL(path)

// After
await browserAPI.runtime.sendMessage(message)
browserAPI.runtime.getURL(path)

Edge-Specific Notes

• Edge uses Manifest V3 like Chrome (no need to convert to MV2)
• Edge uses chrome.* namespace, not browser.*
• The browserAPI wrapper is primarily for:
  • Promise-based consistency
  • Future Edge-specific compatibility handling
  • Unified codebase with Firefox version
• Edge has excellent Chrome extension compatibility

Testing Checklist

After completing the migration, test the following:

• Extension loads without errors in Edge
• Storage operations work correctly (save, load, delete notes)
• Sync functionality works with Supabase
• Context menus appear and function correctly
• Popup opens and displays notes
• Background script handles alarms and messages
• Content script communicates with background script
• Theme settings persist across sessions
• Premium features work correctly
• User engagement prompts display correctly
• Edge-specific features (if any) work correctly

Implementation Priority

Since Edge is very similar to Chrome, the migration can follow the same pattern as Firefox but with less urgency. The main benefits are:

1. Promise-based API for cleaner async/await code
2. Unified codebase across all three browsers
3. Future-proofing for any Edge-specific changes
