5function es(){
6  return gulp.src('./src/index.js')
7    .pipe(gulpTerser({}, terser.minify))
8    .pipe(gulp.dest('./build'));
9}
10
11exports.default = es;

Use sourcemaps

You can use sourcemaps like this:

1const gulp = require('gulp');
2const sourcemaps = require('gulp-sourcemaps');
3const terser = require('gulp-terser');
4
5function es(){
6  return gulp.src('./src/**/*.js')
7    .pipe(sourcemaps.init())
8    .pipe(terser())
9    .pipe(sourcemaps.write('./'))
10    .pipe(gulp.dest('./build'));
11}
