4-14: LGTM! Consider extracting to a constants file if reused.The MIME type mapping is comprehensive and well-structured, covering all common image formats with their correct MIME types.
If these MIME types are used elsewhere in the codebase, consider extracting them to a separate constants file for better maintainability and reusability.

16-77: Consider adding error handling for image processing.While the new image type detection is an improvement, consider adding error handling for scenarios like:
- Invalid image URLs
- Network issues when fetching remote images
- Unsupported image formats
This could involve:
- Adding try-catch blocks around image processing
- Logging errors for debugging
- Providing fallback behavior for failed cases

🛠️ Refactor suggestion
Improve enclosure object creation.
Several improvements can be made to this section:
- The hard-coded length (15026) should be replaced with actual file size
- Base URL concatenation is duplicated
Consider this improvement:
+ const fullUrl = `${base}${post.cover}`;
const enclosure = {
- "@url": `${base}${post.cover}`,
+ "@url": fullUrl,
"@length": 15026, // Dummy value, replace with actual size if available
- "@type": getMimeType(`${base}${post.cover}`) // Pass the full URL to getMimeType
+ "@type": getMimeType(fullUrl)
};Would you like help implementing a function to determine the actual file size of the images? This could involve:
- Using
fs.statSyncfor local files - Making an HTTP HEAD request for remote files

Add missing 'path' module import.
The function uses path.extname() but the path module is not imported.
Add this import at the top of the file:
const fs = require('fs')
const json2xml = require('jgexml/json2xml')
+const path = require('path')Committable suggestion skipped: line range outside the PR's diff.

💡 Codebase verification
Missing path module import and validation needed in getMimeType function
- The
pathmodule is used but not imported inscripts/build-rss.js - The function lacks input validation for null/undefined URLs
- The function is used only internally for RSS feed generation with controlled inputs
- Test coverage is required as per jest.config.js settings
Recommended changes:
- Add
const path = require('path')at the top of the file - Add input validation:
function getMimeType(url) {
if (!url || typeof url !== 'string') return 'application/octet-stream';
const ext = path.extname(url).toLowerCase();
return MIME_TYPES[ext] || 'application/octet-stream';
}- Create test file at
tests/build-rss.test.jscovering:- Valid image URLs with different extensions
- Invalid/empty URLs
- URLs without extensions
- URLs with unknown extensions
🔗 Analysis chain
Add input validation and tests for getMimeType function.
The function needs defensive programming and test coverage:
- URL parameter should be validated
- Function is not covered by tests according to codecov
Would you like me to help with:
- Adding input validation to handle null/undefined URLs?
- Creating unit tests for various scenarios (valid URLs, invalid extensions, null inputs)?
Let's verify the current usage patterns:
Let me gather more context about the usage and implementation to provide a comprehensive verification.
Let me check the test configuration and examine if there are any existing test utilities that could be helpful for testing the getMimeType function.

Improved the image type detection logic in the build-rss.js file by adding a new function to get the image's MIME type from its url rather than going over each if-checks improving the maintainability and readability of the code
