javascript - How do I run gulp eslint continuously and automatically while fixing files -- how to set up watch -

i trying eslint gulp. have set task this:

            gulp.task('lint', function () {                 return gulp.src([             'components/myjs.js'                                   ])                     // eslint() attaches lint output eslint property                      // of file object can used other modules.                      .pipe(eslint())                     // eslint.format() outputs lint results console.                      // alternatively use eslint.formateach() (see docs).                      .pipe(eslint.format())                     // have process exit error code (1) on                      // lint error, return stream , pipe failonerror last.                      .pipe(eslint.failonerror());             }); 

when run gulp lint tells me lot of errors. trying fix them 1 one. have re-run gulp lint manually give me updated report. how set automatically re-run every time update 'components/myjs.js'?

just add watch task:

gulp.task('watch', function() {   gulp.watch('components/myjs.js', ['lint']); }); 

this way gulp track changes on 'components/myjs.js' , execute 'lint' task on change
