An example of how to print out the names of files streamed by gulp. Sometimes useful for debugging purposes.

gulpfile.js

import gulp from 'gulp';
import { Transform } from 'node:stream';

gulp.task('build', () => {
  return gulp
    .src('src/**/*.js')
    .pipe(
      new Transform({
        objectMode: true,
        transform(file, encoding, callback) {
          console.log('FILE:', file.path);
          callback(null, file);
        },
      })
    )
    .pipe(gulp.dest('dist'));
});
