I’m completely infatuated with watch commands and live reloading. It’s like magic. Here are a couple quick commands that I’ve been using with Jekyll:
For Jekyll:
jekyll serve --incremental --host localhost --config _config.yml,_config_dev.yml
And for BrowserSync:
browser-sync start --files "assets/css/*.css" --proxy "localhost:4000" --files "./**/*.md" --reloadDelay "2000" --no-notify"
