Conversation
Moves expensive operations (Date creation, string parsing, toLowerCase mapping) out of the renderPDFs loop and into a one-time prepareSearchIndex step run on data load. Also updates filtering logic to use early returns. Co-authored-by: MrAlokTech <107493955+MrAlokTech@users.noreply.github.com>

💡 What: Added
prepareSearchIndexto pre-calculate_searchStr,_formattedDate, and_isNewduring data load. RefactoredrenderPDFsto use early returns and the pre-calculated search string. UpdatedcreatePDFCardto consume the pre-calculated variables.🎯 Why: Instantiating Date objects and calling
.toLowerCase()on multiple string fields during every keystroke and filter iteration caused excessive CPU overhead and sluggish search performance, especially aspdfDatabasegrows.📊 Impact: Significantly reduces CPU operations during the search filter loop by checking pre-compiled lowercase strings instead of repeatedly recomputing them. Prevents redundant Date object instantiations and formatting during rendering.
🔬 Measurement: Verified using a Playwright script by injecting mock data and asserting that cards are successfully filtered by the pre-calculated
_searchStrwhen the user types in the search input. Tested frontend and confirmed zero visual or functional regressions.PR created automatically by Jules for task 1123171547595540183 started by @MrAlokTech
