  1. Great intro by @michaljanaszek to tracking pre-defined (like First Contentful Paint) as well as custom metrics (a search widget becoming interactive) with headless @googlechrome, aka. Puppeteer. Also teaches how to do network and CPU emulation and deal with Service Workers. 👏 x.com/MartinSchierle/status/1009779333848797184
