Conversation
Implement `prepareSearchIndex` to pre-calculate lowercased search strings and format upload dates exactly once during initial data load. This eliminates the need to perform these computationally expensive operations on the fly within the `renderPDFs` search filter loop and `createPDFCard` component instantiation. * 💡 What: Added `prepareSearchIndex` to pre-calculate derived fields. * 🎯 Why: Recomputing `.toLowerCase()` strings and `new Date()` multiple times per keystroke blocks the main thread. * 📊 Impact: O(1) attribute access vs O(N) string processing per item per keystroke. * 🔬 Measurement: Observe lower CPU overhead via Chrome DevTools during rapid search typing.

⚡ Bolt: Add pre-calculated search indexing for faster rendering
💡 What: Added
prepareSearchIndexto compute derived runtime fields (_searchStr,_formattedDate,_isNew) exactly once when the database loads. Removed repeatedtoLowerCase()andnew Date()instantiation from the.filterloop and thecreatePDFCardfunction.🎯 Why: Previously, searching required performing multiple
.toLowerCase()string conversions and concatenations for every PDF item on every keystroke. Additionally, dates were being instantiated and formatted dynamically every time a card was rendered. This blocked the main thread and caused perceivable lag during typing on slower devices or large datasets.📊 Impact: Reduces per-item processing cost from multi-step string manipulation to a single O(1) string inclusion check (
includes()), improving filtering speeds significantly. Reduces DOM rendering overhead by accessing static pre-formatted strings rather than instantiating new Date objects per card.🔬 Measurement: Verify by typing rapidly in the search bar and observing lower main-thread blocking time in Chrome DevTools Performance tab, leading to a smoother frame rate.
