About xfun
Yihui's utility grab-bag is quietly growing a web server and a headless browser.
xfun is the shared utility layer under knitr, rmarkdown, bookdown and litedown, and its recent releases cluster in three places: the record() function that captures code output for litedown, a local app-serving stack built on R's internal httpd, and a headless-browser toolkit. Version 0.58 replaced direct httpd routing with a proxy and added serve_dir() and random_port(); 0.55 added browser_print() and 0.60 added browser_dom(), which runs JavaScript on a page and returns the rendered DOM.
