Converting es6 script to JS using gulp

I am trying to convert the ES6 code to simple JS, using babel in gulp. Running the below code I am getting [Error in Plugin "gulp-babel"] with Message: [Plugin/Preset files are not allowed to export objects, only functions.]

  var gulp = require('gulp');
  var babel = require('gulp-babel');
  gulp.task('scripts',function(){
      return gulp.src(['src/scripts/app.js'])
      .pipe(babel({presets:['es2015']}))
      .pipe(gulp.dest('build/scripts/'))
  });

src/scripts/app.js

const hello = (name) => {
    return `hello ${name}`; 
};

Guiding me to convert the ES6 code to vanilla JS would be most appreciated.

Solution

  • You're probably using Babel 7, and your preset is not compatible with it. You should install and use { presets: ["@babel/preset-env"] }.
