perf: v0.2.0 — event-based waitForLoad, fast ensureAlive, JPEG screenshots, page info caching
5 performance optimizations (14-36% faster end-to-end, output quality unchanged):
- fast ensureAlive(): WS state check instead of CDP roundtrip (96% faster per-call)
- event-based waitForLoad(): CDP load events instead of 300ms polling (99.5% faster for loaded tabs)
- JPEG screenshot support: 29-49% smaller files, faster CDP transfer
- page info caching: 1s TTL eliminates redundant evaluateJS calls
- parallel domain enables: Promise.all instead of sequential await in switchTab()
Benchmark: 3622ms vs 4243ms baseline on 3-tab navigation + screenshot task.

Uses WebSocket state check + 30s TTL. 96% faster per-call setup. +- **Performance: event-based `waitForLoad()`** — replaces `readyState` polling (300ms interval) with CDP `Page.loadEventFired` / `frameStoppedLoading` event draining (50ms interval). Detects already-loaded pages in ~1ms (99.5% faster). +- **Performance: JPEG screenshot support** — `captureScreenshot()` accepts `format` (png/jpeg) and `quality` (1-100). JPEG q80 is 29-49% smaller than PNG for complex pages, speeding up CDP transfer and reducing LLM context cost. +- **Performance: page info caching** — `getPageInfo()` caches results for 1 second, eliminating redundant `evaluateJS` CDP roundtrips on back-to-back calls. +- **Performance: parallel domain enables** — `switchTab()` enables Page/DOM/Runtime/Network domains via `Promise.all` instead of sequential await. +- **Tools: `browser_screenshot`** now accepts `format` (png/jpeg) and `quality` parameters. +- **Tools: `browser_wait_for_load`** now uses `daemon.waitForLoad()` (event-based) instead of polling. + ## [0.1.0] - 2026-05-02 ### Added |
