Talkat JSConf EU 2019 · 2019-06-01..06-02· [web-performance, security]

Shows concrete headers and outcomes: sets HSTS preload to force HTTPS (explains why .dev is HTTPS‑only), uses CSP report-only to find and then block unwanted third‑party scripts, cites that only 6% of crawled sites use CSP, compares Brotli level 11 vs gzip level 6 and recommends lowering Brotli level for speed, explains Accept-CH client hints to serve WebP or sized images, and warns to use link preload with no‑push to avoid cache duplication.
