const gulp = require('gulp'); const browserSync = require('browser-sync').create(); gulp.task('serve', function(){ browserSync.init({ //proxy: "http://your_site" proxy: { target: "http://your_site" }, open: "external", host: "your_site", port: 3000 }); browserSync.watch("**/*.*").on("change", browserSync.reload); });
