    Usage

    var gulp = require('gulp');
    var babel = require('gulp-babel');
     
    gulp.task('default', function () {
        return gulp.src('src/app.js')
            .pipe(babel())
            .pipe(gulp.dest('dist'));
    });

    API

    babel([options])

    options

    See the babel options, except for sourceMap and filename which is handled for you.

    Source Maps

    Use gulp-sourcemaps like this:

    var gulp = require('gulp');
    var sourcemaps = require('gulp-sourcemaps');
    var babel = require('gulp-babel');
    var concat = require('gulp-concat');
     
    gulp.task('default', function () {
        return gulp.src('src/**/*.js')
            .pipe(sourcemaps.init())
            .pipe(babel())
            .pipe(concat('all.js'))
            .pipe(sourcemaps.write('.'))
            .pipe(gulp.dest('dist'));
    });

    Babel Metadata

    Files in the stream are annotated with a babel property, which contains the metadata from babel.transform().

    Example

    var gulp = require('gulp');
    var babel = require('gulp-babel');
    var through = require('through2');
     
    function logFileHelpers() {
        return through.obj(function (file, enc, cb) {
            console.log(file.babel.usedHelpers);
            cb(null, file);
        });
    }
     
    gulp.task('default', function () {
        return gulp.src('src/**/*.js')
            .pipe(babel())
            .pipe(logFileHelpers);
    })

    Runtime

    If you are attempting to use features such as generators, you will need to pass { optional: ['runtime'] } to include the babel runtime. Otherwise you will receive the error: regeneratorRuntime is not defined.

    var gulp = require('gulp');
    var babel = require('gulp-babel');
     
    gulp.task('default', function () {
        return gulp.src('src/app.js')
            .pipe(babel({ optional: ['runtime'] }))
            .pipe(gulp.dest('dist'));
    });
