API

traceur([options])

See the Traceur options.

options

modules

Type: string
Default: commonjs
Values: See traceur modules option

By default, gulp-traceur treats all files as modules. This allows use of the export, module and import syntax. In this way the transformer can be used to compile ES2015 for AMD or Node.js environments.

traceur.RUNTIME_PATH

Absolute path to the Traceur runtime.js file.

Source Maps

Use gulp-sourcemaps like this:

const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');
const traceur = require('gulp-traceur');
const concat = require('gulp-concat');

gulp.task('default', () =>
	gulp.src('src/*.js')
		.pipe(sourcemaps.init())
		.pipe(traceur())
		.pipe(concat('all.js'))
		.pipe(sourcemaps.write('.'))
		.pipe(gulp.dest('dist'))
);
