babel output filename option

Question

What is the babel option to rename output transpiled file.

With babel-cli it is -o

babel script.js -o script.transpiled.js

Is there a corresponding babel option that can be used with gulp-babel ?

Answer 1

As filename is handled for you by gulp-babel, you might want to use gulp-rename as an additional pipe

var rename = require('gulp-rename');

gulp.task('default', () =>
    gulp.src('script.js')
        .pipe(babel({
            presets: ['@babel/env']
        }))
        .pipe(rename(function(path) {
          path.basename = 'script.transpiled';
          path.extname = '.js';
        }))
        .pipe(gulp.dest('dist'))
);
