Localization Support for Extension #5
Conversation
WalkthroughThis pull request introduces localization support for a YouTube summarization extension by adding new JSON files for English and Turkish localization. It modifies several JavaScript files to utilize these localization strings, enhancing user interface elements and error handling. The manifest file is updated to reference localized messages for the extension's name and description. Additionally, HTML and JavaScript files are adjusted to support dynamic language selection and notifications, ensuring a more user-friendly experience for speakers of multiple languages. Changes

177-177: Simplify conditional using optional chainingYou can simplify the condition by using optional chaining, which makes the code more concise and readable:

224-224: Consider removing console.log statements in productionThe
console.logstatements used for debugging may not be necessary in the production environment and could clutter the console.Consider removing or commenting out these statements:
// Line 224 -console.log(chrome.i18n.getMessage("summarizeButtonClicked")); // Line 260 -console.log(chrome.i18n.getMessage("summarizeButtonClicked"));Also applies to: 260-260
193-195: Use more robust selectors for YouTube elementsThe DOM selector used to find the subscribe button is very specific and may break if YouTube updates their layout:
const subscribeBtnDiv = document.querySelector("#subscribe-button > ytd-button-renderer > yt-button-shape > a > yt-touch-feedback-shape > div");Consider using a more resilient selector. For example, selecting by ID or using a query that is less likely to change:
const subscribeBtnDiv = document.querySelector("#subscribe-button");Or use feature detection methods to ensure the button is accurately selected regardless of DOM changes.
3-3: EnhancegetVideoIdFromUrlto handle different URL formatsThe current implementation only extracts the video ID from URLs with a
vparameter, but YouTube videos can have different URL formats, such ashttps://youtu.be/VIDEO_ID.Consider enhancing the function to handle various YouTube URL formats:
function getVideoIdFromUrl(url) { const urlObj = new URL(url); let videoId = urlObj.searchParams.get('v'); if (!videoId && urlObj.hostname === 'youtu.be') { videoId = urlObj.pathname.slice(1); } return videoId; }src/popup.html (1)
3-3: Update thelangattribute to match the default localeThe
langattribute is set to'tr', but the default locale in your manifest is'en'. This can affect accessibility tools and search engines.Consider setting the
langattribute to'en'or dynamically updating it based on the user's selected language:-<html lang="tr"> +<html lang="en">Or use JavaScript to set it dynamically:
<html id="html-root">// In your popup.js document.getElementById('html-root').setAttribute('lang', chrome.i18n.getUILanguage());src/popup.js (3)
8-12: Add error handling for storage operationsWhile the implementation is correct, it would be beneficial to handle potential storage errors.
chrome.storage.sync.get(['preferredLanguage'], (result) => { + if (chrome.runtime.lastError) { + console.error(chrome.i18n.getMessage("storageError"), chrome.runtime.lastError); + return; + } if (result.preferredLanguage) { languageSelect.value = result.preferredLanguage; } });
15-23: Add error handling for storage operationsSimilar to the previous section, add error handling for the storage operation.
chrome.storage.sync.set({ preferredLanguage: selectedLanguage }, () => { + if (chrome.runtime.lastError) { + console.error(chrome.i18n.getMessage("storageError"), chrome.runtime.lastError); + return; + } console.log(chrome.i18n.getMessage("languageSavedConsoleLog"), selectedLanguage); showNotification(chrome.i18n.getMessage("languageSavedNotification")); });
57-67: Use optional chaining for safer accessThe code can be improved using optional chaining as suggested by the static analysis.
-if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) { +if (window.matchMedia?.('(prefers-color-scheme: dark)')?.matches) { document.body.classList.add('dark-mode'); }src/_locales/en/messages.json (1)
1-83: Consider adding placeholders for dynamic contentSeveral error messages might need to include dynamic content (e.g., error details). Consider using Chrome i18n placeholders.
Example for
unexpectedError:"unexpectedError": { - "message": "An unexpected error occurred:" + "message": "An unexpected error occurred: $ERROR$", + "placeholders": { + "error": { + "content": "$1" + } + } }src/_locales/tr/messages.json (1)
56-76: Consider adding RTL support for error messagesTurkish text might need RTL (Right-to-Left) support in some contexts. Consider adding
dir="auto"in the HTML elements where these error messages are displayed.

2-2: LGTM! Verify i18n implementation completeness
The manifest changes correctly implement Chrome extension i18n support by:
- Adding the required
default_localefield - Using proper message reference format for name and description
Let's verify the i18n implementation is complete:

✅ Verification successful
i18n implementation is complete and correctly structured
The verification confirms that:
- Required locale structure exists with both English (en) and Turkish (tr) translations
- Both referenced message keys (
extensionNameandextensionDescription) are properly defined in both language files

The following scripts were executed for the analysis:

1-83: Verify translation completeness and consistency
The Turkish translations look good, but let's ensure completeness and consistency with the English locale.
✅ Verification successful
Let me try a different approach to verify the translations.
Turkish translations are complete and consistent with English locale
The verification shows that:
- All message keys from English locale are present in Turkish locale
- Both files have identical set of 27 keys
- No empty messages were found in Turkish translations

Use localization key for the error message
The error message is still hardcoded, breaking localization support.

14-106: Extract common styles to reduce duplicationThe modal dialog implementation has duplicate styling code for buttons. Consider extracting common styles into a helper function.

'#555' : '#f0f0f0', color: isDarkMode ? 'white' : 'black', border: isDarkMode ?

3-4: LGTM! Robust URL parsing and proper localization implementation
The changes improve code reliability by:
- Using the URL API for parsing instead of manual string manipulation
- Properly implementing localization with a fallback mechanism
Also applies to: 8-10
155-163:
Parameterize the server URL for different environments
The hardcoded localhost URL needs to be configurable for different environments.
191-263: 🛠️ Refactor suggestion
Extract summarize button creation logic to reduce duplication
The button creation and styling code is duplicated between the primary and fallback paths.
