31-31: LGTM! Consider documenting the cache time parameter.The addition of a 24-hour cache time is a good default for static assets, especially when combined with ETag validation. This will help improve performance for ESP32-served content.
Consider adding a comment in the README about the new
--cachetimeparameter and its impact on browser caching behavior.

57-59: Verify compatibility with the updated dependencies.The dependency updates look reasonable, with synchronized updates for the TypeScript ESLint packages.
Please verify that the build and tests pass with these updates:
✅ Verification successful
Dependencies are properly synchronized and follow semver guidelines
The package-lock.json is in sync with all three dependency updates, and the TypeScript ESLint packages are correctly updated to the same version. These minor and patch updates should maintain backward compatibility.

1-29: Document the default cache time value.The script uses a 24-hour (86400 seconds) cache time across all commands. This should be documented to explain the choice of this default value.
Consider adding a comment at the top of the file:
+# Default cache time is set to 24 hours (86400 seconds) +# This provides a good balance between caching benefits and content freshnessAdditionally, consider making the commands DRY-er by extracting common parameters into variables:

7-7: Enhance the changelog entry with more details.While the entry correctly describes the new feature, it could be more helpful with additional details.
Consider expanding the changelog entry:
-- Using the cachetime command line option, you can set whether the browser can cache pages. Together with the ETag switch, you can replace the default no-cache response with a max-age=xy response. +- Added `--cachetime` command line option to control browser caching behavior: + - Default: no-cache (when option is not provided) + - Example: `--cachetime=86400` sets Cache-Control: max-age=86400 (24 hours) + - Works in conjunction with ETag for optimal caching strategyREADME.md (2)

Update @sveltejs/vite-plugin-svelte to latest version for Vite 6 compatibility
The current version (5.0.3) of @sveltejs/vite-plugin-svelte needs to be upgraded as Vite 6 requires a newer version of this plugin. Other Vite-related dependencies are compatible:
- vite-plugin-tailwind-purgecss: Already supports Vite 6
- @sveltejs/vite-plugin-svelte: Needs upgrade to latest version

🛠️ Refactor suggestion
Add validation for the cachetime parameter.
The cachetime parameter should be validated to ensure it's a non-negative value and within reasonable bounds for max-age cache control.
Consider updating the type definition to include validation:
- cachetime: number;
+ cachetime: {
+ type: (value: number) => number;
+ description: 'max-age cache time in seconds';
+ defaultValue: 0;
+ validate: (value: number) => {
+ if (value < 0) throw new Error('Cache time cannot be negative');
+ if (value > 31536000) throw new Error('Cache time cannot exceed 1 year (31536000 seconds)');
+ return value;
+ }
+ };Committable suggestion skipped: line range outside the PR's diff.
