BrowserSync custom host domain + snippet options

browsersync.js

  const browserSync = require('browser-sync').create();
  const port = process.env.PORT || 8080;
  const customDomain = environment.DEV_DOMAIN ? `${environment.DEV_DOMAIN}` : 'localhost';
  browserSync.init('**/*.css', {
    logPrefix: 'Showroom:',
    proxy: `localhost:${port}`,
    open: false,
    host: customDomain,
    port: 3000,
    ghostMode: false, /* don't mirror interactions in other browsers */
    snippetOptions: {
      rule: {
        match: /<\/body>/i,
        fn: (snippet) => snippet,
      },
    },
  });

still works :)
