Unexpected token ILLEGAL with @inject

Question

I'm using gulp-jshint and receiving this message with a javascript file. The file is a simple service class in my Aurelia app. Here is the code:

import {inject} from 'aurelia-framework';
import {MyService} from './app/service/MyService';

/* jshint ignore:start */
@inject(MyService)
/* jshint ignore:end */
export class App {

    constructor(MyService) {
        this.message = MyService.message;
    }

}

Here is my gulp task (gulp-jshint is getting loaded using gulp-load-plugins):

gulp.task('vet', function() {
    return gulp.src(config.alljs)
        .pipe($.if(args.verbose, $.print()))
        .pipe($.jscs())
        .pipe($.jshint())
        .pipe($.jscsStylish.combineWithHintResults())
        .pipe($.jshint.reporter('jshint-stylish', {verbose: true}))
        .pipe($.jshint.reporter('fail'));
});

I have "esversion": 6 in my .jshintrc

This is the result of running gulp vet (in both Powershell and cmd)

The Aurelia app works just fine. JSHint is ignoring the @inject within VSCode also, no problem there. For some reason, though, gulp-jshint won't let it go. I've deleted and retyped the line after searching and finding a lot of issues with non-printable characters. I've tried switching the jshint ignore to // jshint ignore:line syntax. Still nothing.

Is there something I'm missing?

Answer 1

JSHint does not support decorators ("@whatever") yet, so esversion: 6 will not affect this issue.

The policy of JSHint is to support features that are Stage 2 of standardization process, which is not the case yet for decorators.

Not sure why your "ignore" directive is failing, though. Maybe try the single-line ignore directive? @inject(MyService)// jshint ignore:line

Edit: Ignoring a single line doesn't work for me either. Sorry, this answer probably won't be helpful. :-(
