Error: The variable $traceurRuntime has not been defined in the AngularJS application

Currently, I am utilizing [gulp-traceur][1] to convert es6 to js within my angularjs application (version 1.x). However, when attempting to compile a for loop, an error occurs:

ReferenceError: $traceurRuntime is not defined

It appears that I may need to inject $traceurRuntime into my controller or another component. Is there anyone who can provide assistance with this issue?

Answer №1

$traceurRuntime is a special object that resides in the global scope and is not considered an Angular injectable. This object is brought into existence by including the traceur runtime script file (traceur-runtime.js) within your application. It's important to ensure that you incorporate the traceur.RUNTIME_PATH so that the gulp task can locate it effortlessly during compilation and include it accordingly.

If your gulpfile resembles the following:

// gulpfile.js
var traceur = require('gulp-traceur');

// ...

gulp.task('build', function() {
  return gulp.src([
    traceur.RUNTIME_PATH, // <-- don't forget this addition
    'src/**/*.*'
  ])
  .pipe(traceur({ /* configuration for traceur */ })
  .pipe(gulp.dest('/dist'));
});
