let rename = require("gulp-rename");
var sourcemaps = require('gulp-sourcemaps');
let uglify = require('gulp-uglify-es').default;
 
gulp.task("uglify", function () {
    return gulp.src("lib/bundle.js")
        .pipe(rename("bundle.min.js"))
        .pipe(sourcemaps.init())
        .pipe(uglify())
        .pipe(sourcemaps.write()) // Inline source maps.
        // For external source map file:
        //.pipe(sourcemaps.write("./maps")) // In this case: lib/maps/bundle.min.js.map
        .pipe(gulp.dest("lib/"));
});
