fix: include temporal polyfill source map to resolve 404 error #161
Conversation
|
@copilot please address the issues now that you have the latest code from develop. |
The temporal package was failing to load with a 404 error for index.umd.js.map because the copy-assets script was only copying the main JavaScript file but not the source map. This caused the develop site to be slow and the Date Selector to not work properly. Updated copy-assets script to include both index.umd.js and index.umd.js.map files from @js-temporal/polyfill package. Co-authored-by: tsmarvin <[email protected]>

The problem was that the build script was only copying the main JavaScript file but not the source map file, causing a 404 error for Updated the copy-assets script to include both files from the @js-temporal/polyfill package. The Date Selector is now working and the site loads without timeouts. Commit: 6e67767

Pull Request Overview
This PR fixes a critical 404 error that was causing the temporal polyfill to fail loading its source map file, resulting in extremely slow site performance and broken Date Selector functionality. The fix includes both the source map file in the build process and updates the temporal library loading approach.
Key changes:
- Updates the copy-assets script to include the temporal polyfill source map file
- Refactors temporal library loading from module imports to global script loading
- Adds comprehensive test coverage for DST transitions, version deployment, and accessibility

Hard-coded absolute path makes tests brittle and non-portable. Consider using path.join(process.cwd(), 'dist', 'index.html') to make the path relative to the project root.

Accessing window.SunCalc without null checking could cause runtime errors if the script fails to load. Consider adding a null check or fallback handling.

| // Defensive check for SunCalc presence | |

Console.warn statements should not be present in production code as they can expose implementation details and clutter browser console. Consider using a proper logging mechanism or removing this log.
| console.warn(`SunCalc failed for timezone ${timezone.iana}:`, error); | |
| // TODO: Add error logging here if needed (SunCalc failed for timezone) |

CSS custom property --color-surface-accent is used but its definition appears later in the file. Consider organizing CSS custom properties at the top to avoid potential undefined variable references.
The temporal package was failing to load with a 404 error for
index.umd.js.mapbecause the copy-assets script was only copying the main JavaScript file but not the source map. This caused the develop site to be extremely slow to load and the Date Selector to not work properly.Root Cause
The build script in
package.jsonwas only copyingindex.umd.jsfrom the@js-temporal/polyfillpackage but browsers were also requesting the corresponding source map fileindex.umd.js.map, which resulted in a 404 error.Solution
Updated the
copy-assetsscript to include both files:Verification
- All network requests now return 200 OK responses
- Date Selector functionality is fully restored
- Site loads quickly without timeouts
- Timeline visualization renders correctly
Fixes #160.
